Characteristics of membrane when making Membrane Switch panel Thin film is important for both thin film switches and thin film panels. In the production, each material is carefully selected. Only in this way can we produce high-quality Membrane Switch and membrane panels. When selecting materials, we pay special attention to films, which can be seen from the name. So, what characteristics or advantages should the film have when making the film switch and film panel? Now let's understand. Characteristics of membrane when making Membrane Switch panel 1. Good weather resistance: the panel layer is the surface layer of the Membrane Switch exposed to the natural environment. The panel material shall be able to avoid deformation, cracking, aging and discoloration under certain natural environmental conditions. 2. Good dimensional stability: theMembrane Switch is required to make the membrane of the panel, and there is no obvious change in the dimension within a certain temperature range (generally - 40 ℃ ~ 55 ℃). 3. Elastic requirements: the panel layer is required to be thin and have certain resilience. At the same time, the elastic deformation of the Membrane Switch should be small, which can be judged by the elongation of the material. Generally speaking, the elongation is large, the elastic deformation is also large, and the elastic performance is poor. 4. Good appearance: it means that the film surface of the panel is flat and consistent in luster, without mechanical damage, scratches, inclusions, color spots and other surface defects. 5. Good chemical resistance: the panel layer may touch different chemicals, but it should have certain resistance to most common chemicals, such as alcohols, ethers and mineral oils. The above is about the characteristics of thin film when making thin film switch and thin film panel. Only with these characteristics can we produce high-quality thin film switch. If you need thin film switch and thin film panel, you can contact us.

What are the differences between membrane switch and touch switch Due to the breakthrough in technical materials, membrane switches have made great progress in the markets of waterproof, insurance and reliable performance. Also because of its convenient installation and the decline of profit, membrane switch has gradually begun to replace the application field without touch switch. What about the difference between membrane switch and touch switch? Let's explain it to you. The volume of light touch switch is small, which is a standard part. The measurement and related parameters must be standardized by the joint enterprise, and there are many colors; The membrane switch can be customized according to the owner's requirements, with unique size, appearance and color. It is more convenient and sensitive to use. The membrane switch has good hardness, open structure and waterproof structure, and has better adaptability to conditions. The cost and price of touch switch are lower than planned, and there is no large price adjustment due to the stability of raw materials in the market; Compared with the membrane switch, the price is high and the volume is large, which is greatly affected by the price of raw materials. Both the light touch switch and the membrane switch belong to functional switches. When the light touch switch is used, the switch can be turned on by quietly pressing the switch button. When the hand is released, the switch can be turned off. Its internal structure is realized by the force bouncing of metal shrapnel. Membrane switch is a key with its own leading line. Generally, the top layer is a panel with words or patterns composed of materials such as pet or PC, the lower layer is a thermally conductive line, the central layer is a double-sided adhesive made of PET data that imitates the switching mode and plays an isolation role, and the bottom part is generally the contact and receiving line on PET material. When pressing the key position on the surface layer with the finger, the key contact shall be in position contact with the contact on the upper layer to form a DC connection. The rise of membrane switch is quite professional. In fact, the simple one is the panel type button. This name is relatively familiar. The control panels of many facilities use membrane switches, which are widely used in the fields of electronic communication, electronic measurement instruments, light industry, medical facilities, public cars, light industry, intelligent toys, household appliances and so on. Membrane switch is a multi-layer structure (three-dimensional) type (non locking) key switch composed of insulating data layer with definite inertia. It integrates the functions of keys, instruction parts, instrument panel and so on. Membrane switch has the characteristics of beautiful appearance, long service life, simple structure, convenient installation, good hand feeling and small occupied area. It is widely used in all walks of life, from household appliances to high-tech products. It has gradually replaced some light touch switches in the market and is holding a great share in the market. The basic task principle of the film is as follows: when the back plate is not pressed, the film switch is in the general form, its upper and lower contacts are disconnected, and the isolation layer acts as an isolation for the upper and lower lines. When the membrane plate is pressed, the contact of the upper channel deforms downward and reconnects with the lower route to make the route conductive. The conductive route gives signals to the internal connecting instruments, so as to complete its echoing performance. When the finger is grasped, the upper path contact pops up and returns, the path is cut off, and the circuit triggers a one-degree signal.

Classification of Membrane Switch 1. Flat non tactile type: long service life, but no tactile; 2. Film convex tactile type: Membrane Switch has good tactile feeling, but its service life is relatively short; 3. Convex frame non tactile type: beautiful appearance, strong three-dimensional feeling, but no tactile feeling; 4. Convex frame tactile type: beautiful appearance, strong three-dimensional feeling and tactile feeling; 5. Convex touch type of surface plate:Membrane Switch. (a) Type: when the design is not appropriate, Membrane Switch is easy to have two sections, but the surface plate is damaged and the electrical performance also exists; (b) Type: there is no two-stage phenomenon, and there are few structural layers, which is more economical. If the surface plate is damaged, the electrical performance will not exist; 6. Metal shrapnel type: (a) Type: it is the most basic and commonly used structure. The shrapnel not only plays the role of touch, but also plays the role of wiring; (b) Type: complex structure. It is used when there are many and dense shrapnel and there is no jumper. The shrapnel is placed on the upper and lower lines, the conductive surfaces of the upper and lower lines are upward, and the upper line needs punching. When this structure is conductive, the four feet of the shrapnel are not in the same plane with the center point, and there are "two sections" The situation occurred. At the same time, the shrapnel is often in the strong state of excessive anti concave. Over time, the shrapnel will not rebound, so it is not recommended to use; (c) Type: the shrapnel is placed on the upper line and only plays the role of touch. The upper line conductive faces down and the lower line conductive faces up. There are "two sections", which is not recommended; (d) Type (b): the shrapnel is placed on the lower line, and the upper and lower lines are wired. The shrapnel not only plays the role of touch, but also plays the role of connecting the upper and lower lines. It is used in the situation where there are many shrapnel, dense and there is no jumper. The structure is simpler than type (b). During the design, pay attention to the line routing, and avoid the four legs of shrapnel to ensure no short circuit.Membrane Switch. 7. Luminous body type: the primer mold must be opened; (a) The LED line is on the same layer as the lower line: the structure is simple, but if the selected LED lamp is high, the LED lamp will jack up the panel. At this time, the LED window on the panel should be convex, or the thickness of the surface adhesive layer should be thickened to make its thickness greater than that of the LED lamp; (b) The LED line is different from the lower line: the structure is complex, but the LED window does not have to be convex, but the upper area of the LED lamp must be hollowed out to prevent light from passing through the LED lamp hole. Note: at this time, it is necessary to avoid routing around the LED light hole when routing the line. 8. Folding type: This type can avoid jumpers, and there is no need to fill holes, so that the conductive surface can be downward. The disadvantage of this structure is that Membrane Switch it is easy to fold in half and the line is easy to break. 9. Waterproof type of inner and outer frames: The outer frame is a closed frame without wiring, which protects the inner frame and prevents moisture from entering the casing from the outlet groove.Membrane Switch

Effect of PET film on Membrane Switch 1. What is a Membrane Switch. Membrane Switch, also known as light touch keyboard, is a plane multi-layer integrated sealing structure and an open key panel. The sign display is sealed with the lining plate, which is a new electronic component integrating light, machine and electricity. It is a fundamental change in the appearance and structure of electronic products. It can replace the buttons of traditional discrete components, so that the operating system can complete the work of the operating system more reliably. 2. What is the structure of Membrane Switch. The board is the "coat" of the whole membrane switch, and its main function is to play the role of sign and button. The upper and lower circuits are not only the electrical components of the Membrane Switch, but also the "shutdown" and "key" of the switch, but its performance directly affects the performance of the switching device. This method is formed by coating a layer of conductive material on the film. The upper and lower circuits are responsible for the two impact characteristics required to close the Membrane Switch. The thickness is usually 0.05-0.175mm, usually 0.125mmpet. What are the advantages of Membrane Switch? 1. The electronic component integrating switch function and decoration function is a new man-machine dialogue interface. The connection mode between the switch circuit and the whole machine can be completed by welding or plugging. 2. The main type of Membrane Switch is a membrane switch panel, which is a plastic membrane panel with hard or flexible printed circuit board as the matrix, installed between the hand feeling and the hand feeling, and then covered with color decorative patterns. 3. Membrane Switch is waterproof. Dust proof. Oil proof. Resistant to harmful gas erosion. Stable and reliable performance. Light weight, small volume and long service life. It is easy to assemble and connect, the panel is cleaned and not easy to be damaged, and the panel is not easy to be damaged, rich in color and beautiful. The use of film switch makes your product more contemporary.

How to test the quality of Membrane Switch At present, the goods used in society are products that pass inspection, quality and safety and do less harm to human body. Only in this way can they be accepted by consumers and popular in society. Without inspection standards, products are difficult to circulate in the society and realize value; For the sake of safety, high quality testing standards are very necessary. Membrane switch has a wide range of applications and can be seen in major equipment. Its detection can not be relaxed, otherwise it will have a significant impact. Only genuine Membrane Switch can be reflected in the use process, and still be strong at the time of inspection. The general process of Membrane Switch detection cannot be relaxed, otherwise it will cause great harm to human body. The following steps are required to check whether the quality of the film switch is qualified: there shall be no obvious difference in the color of the same batch of products, and the color printing layer shall have sufficient covering power, subject to the color and structure below which can not be seen by the reflected light; When printing the transparent ink layer, the two-color overlapping part shall not exceed 1mm, and the color deviation caused thereby is allowed; The edges of printed characters and color blocks are not clear, no more than 0.15mm. The size of the Membrane Switch shall comply with the provisions in Table 1. The parallelism and perpendicularity of two adjacent sides of the membrane switch shall comply with the provisions. The center distance between adjacent conductors at the end of the lead strip is generally 2.54mm. This is the basic detection standard, among which there are more complex detection standards. No matter what the high-quality Membrane Switch detection standard is, it is to enable the qualified membrane switch to be applied, so that it can produce the best effect in the process of use, and reduce the occurrence of major bad things due to poor quality.

Membrane switch has played an important role in the electronic industry since its birth, but it is limited to some components and can not complete the whole process of component processing, but it has made a contribution to improving the appearance and decoration of electronic products. So what is the role of membrane switches in the electronic industry? Membrane switch is an independent electronic industrial product integrated with screen printing technology. It can not only decorate the appearance of instrument panel, but also have the function of complete operating components. From this point of view, it can be said that it integrates decoration and function. It can be said that it is the product of the development of screen printing technology, but also promotes the development of printing technology to a certain extent. In the operating system of electronic products with Membrane Switch in the past, it may be limited by the appearance of commercial products because of its large size and single function, and it is difficult to meet the needs of multi-function, miniaturization, intensive and intelligent development of electronic products. Therefore, a new generation of switching element Membrane Switch came into being, Its birth not only provided timely help for the development of electronic industry, but also loved by the electronic industry. At that time, it had many names: Membrane Switch, touch switch, touch button, electronic panel, etc. The Membrane Switch and membrane switch keyboard are named because of their material characteristics. Their overall sealing structure is generally composed of three or more layers of membranes, which integrates keys, switches, panel function symbols, reading display window, indicator light window, on-off interconnect, switch circuit outgoing line and characters to be marked on the conventional panel Symbols and decorative contents form components of an electronic operating system.

Main characteristics of Membrane Switch 1. Small and light: the weight of general membrane switch ranges from a few grams to tens of grams, which is very easy to carry and disassemble; 2. Beautiful: modern perfect silk screen printing technology and perfect design can make any pattern you need; 3. Sealing: using unique technology, the membrane switch can have the functions of waterproof, oil, pollution and electrostatic interference; 4. Excellent conductivity: the circuit of the switch can be printed with carbon paste, silver paste, copper platinum, etc., and the conductive layer can be folded at will; Moreover, the resistance can be controlled at any resistance you want, and the membrane switch made by using unique technology can even accept more than 100000 V high-voltage electric shock without damaging its function; 5. Low cost: the price of some membrane switches is even only a few cents. Compared with such a multifunctional electronic original device product, the price of Membrane Switch advantage is not comparable to that of other similar products. 6. Long service life: because the materials used in the membrane switch have good insulation, heat resistance, folding resistance and high resilience; In addition, the patterns are printed on the back, so that the silk screen patterns will not be damaged; Therefore, the service life of Membrane Switch can generally reach more than three years.

Matters needing attention in transportation of Membrane Switch Membrane switches have certain precautions during production, transportation and storage. Only in this way can the normal use of membrane switches be guaranteed. Then, what should we pay attention to? 1. Pay special attention to the outlet of the membrane switch when packing and placing it. Make sure that the outlet direction of the membrane switch is above. 2. For membrane switches with visible windows, be careful not to bend the membrane switch due to force when taking and storing, otherwise there will be unrecoverable creases, which will cause damage to the Membrane Switch. 3. A layer of bubble film needs to be laid on the membrane switch in order to perform key reduction work for the pressing of the membrane switch, so that it will not cause damage to the keys and should be stored. 4. There will be a layer of transparent film on the front and back of the Membrane Switch to protect a flash window of the membrane switch. Do not tear off this layer of film when in use. 5. When taking the Electroluminescent Lighting Membrane Switch, be extra careful to avoid scratching. After taking it, the rest should be placed neatly and restored to its original state. 6. When the number of Light Emitting Diodes Membrane Switch is relatively large, when packing the box, pay attention to the switch panel not to lay flat, but to stand upright, so as to effectively prevent the membrane switch buttons from being damaged under heavy pressure for a long time. The above are the precautions during the sealing and transportation of the membrane switch. What are the precautions for the storage of the membrane switch? When the membrane switch is stored and placed, it must be dust-proof and moisture-proof to ensure that there are no strong acids, strong alkalis or other corrosive gases and substances in the storage environment. At the same time, we must do a good job of preventing pests. These are some precautions for membrane switches, I hope it can be helpful to you.

The application of Pressure Measurement Sensor in the field of mechanical automation is very important. When Industry 4.0 is widely popularized, the use of force sensors is becoming more and more widespread. The China FSR Pressure Sensor is actually a device that converts the quality signal into a measurable electrical signal output. The actual working environment of the China FPC Pressure Sensor should be considered when selecting the sensor. This is very important for the correct selection of the load cell. It is related to the normal operation of the sensor, its safety and service life, and the reliability and safety of the entire weighing instrument. sex. Resistance strain gauge load cell is mainly composed of elastomer, resistance strain gauge and compensation circuit. The elastic body is the force-receiving element of the load cell, which is made of high-quality alloy steel or high-quality aluminum. The resistance strain gauge is made by corroding metal foil into a grid shape, and the four resistance strain gauges are glued to the elastic body in the structure of electric bridge. In the absence of force, the resistance values of the four resistors of the bridge are equal, the bridge is in a balanced state, and the output is zero. When the elastic body is deformed by force, the resistance strain gauge also deforms along with it. In the process of bending of the elastic body under force, two strain gauges are stretched, the metal wire becomes longer, and the resistance value increases; the other two pieces are pressed, the resistance value decreases. This causes the original balanced bridge to be unbalanced, and a voltage difference is generated at both ends of the bridge. This voltage difference is proportional to the force of the elastic body. By detecting this voltage difference, you can get the gravity of the sensor. After the voltage signal is detected by the meter and then calculated, the corresponding weight value can be obtained. In the basic concepts and evaluation methods of the main technical indicators of the load cell, there are qualitative differences between the new and the old national standards. There are several styles such as S type, cantilever type, spoke type, plate ring type, bellows type, bridge type, column cylinder type and so on. The load cell is divided into four-wire system and six-wire system. The difference is that the six-wire sensor has two more feedback wires (SEN+ and SEN-). These two wires are used for compensation. When the distance between the modules is far, the two wires will be compensated to make the measurement result more accurate. The output signal of the China Force Pressure Sensor is generally 2.0mv/v, and some output 3.0mv/v. The specific output signal calculation method of the load cell is: For example, the model PLD204L4-20-50Kg, the sensitivity is 2.000mv/v. The power supply voltage is DC10V. When the loaded weight is a rated load of 50Kg, the output signal is 2.000mv/v times 10V times 1=20mv, and when the loaded weight is 25KG, it outputs 10mv. In the automated electrical system, the signal of the load cell is generally collected by the PLC or the acquisition card. The PLC and the acquisition card collect the standard analog signal, so when using the selected load sensor, it is necessary to select the transmitter BSQ-RM to output the simulation. The display control instrument PH50-A can be selected to realize the control communication function.

The production process of membrane switch includes printing conductive circuit, printing panel layer picture product LOGO, packaging, sealing and other processes. Regardless of the type of switch, the most fundamental effect of the product is the effect of power-on and power-off. Together with this function, without affecting the basic function, we are constantly developing the multi-function of the switch. The Printed Circuit Board Membrane Switch is the most representative commodity in the switch profession. Compared with the button switch, the Pressure Touch Membrane Switches not only has the effect of turning off the power of the button switch, but also has the decoration function that other switch products do not have. The switch panel layer printed with silk screen technology selects specific inks and printing technology to cooperate with each other, so that the pictures printed on the panel layer have the characteristics of long-term non-discoloration and strong adsorption to the material itself. The service life of the Silver Flex Membrane Switches will vary according to the changes in the environment. The membrane switch produced from poly carbonate PC and PVC material can reach more than 5 million times from the point of view of the button, and the time of damage from the data point of view Usually 3-10 years. No matter from which aspect, it has materials that other switches (push button switches) cannot. Regardless of the production technology, the quality of the product, and the planned appearance, the most basic characteristics have been greatly improved.

Specification of membrane switches in the electrical industry: Membrane switch has a multi-layer structure of key switches. Because of its beautiful appearance, long life, simple structure and other characteristics, membrane switches are widely used in all walks of life. Such as Light Guide Film Membrane Switch and Electroluminescent Lighting Membrane Switch. From small home appliances to large high-tech products, they are inseparable from the control of membrane switches. Let Dongguan Nanhuang Industry Co., Ltd analyze the use of electrical membrane switches. Membrane switches are mainly composed of films, film glue, and various layers of circuit boards. The principle of electrical membrane switch: When the Flexible Membrane Switch layer of the electrical appliance is not pressed, the barrier layer has a barrier effect on the circuit of the membrane switch. When the mask layer is pressed, the upper circuit is pressed simultaneously and overlaps with the lower circuit, so that the circuit is turned on. The connected line gives signals to the external connection instrument (set by the customer) to complete its corresponding functions. Membrane switch operation request: The surface of the object to be installed is flat and rust-free, and it can be installed after cleaning.

1. Optical The principle of the optical Panel Rapair Membrane Switch is based on the principle of receiving and blocking the light source. The range of the panel is filled with the light source and the receiver to form a matrix. When the light is blocked, the position of the receiver that cannot receive the signal can be known, and then it can be determined. Precise location. The components of an optical touch panel include a glass substrate, an infrared emitting source, and an infrared receiver. The method of installation is to place the infrared transmitter on the left and lower sides of the glass panel, and install infrared receivers on the right and upper sides. When the infrared rays are blocked by a finger or contact, the information received by the receiver can be measured. The matrix position of the contact point. The advantage is that the surface is pure glass, which does not affect the light transmittance, has high reliability, scratch resistance, and good fire resistance, but the disadvantage is that it has poor waterproof and stain resistance. Generally used in the use of ATM, OA business machines, and medical equipment. 2. Sonic The sonic touch panel is composed of a transmitting transducer, a receiving transducer, a reflector and a controller. The composition and sensing principle of the sonic touch panel is to install a transmitting transducer, a reflecting plate, and a receiving transducer on the X and Y axes of the glass and on the opposite sides, plus a controller to form a sonic touch panel . The sensing action method first sends a 5MHz electronic signal from the controller to the transmission transducer, which is converted into ultrasonic waves by the transmission transducer, and is directly transmitted through the surface of the touch panel to the reflector array, which is on the opposite corner of the reflector. After receiving the ultrasonic wave, the sound wave is collected and sent to the receiving transducer to be converted into an electronic signal, and then transmitted to the controller to store the signal information in the normal state. When using a touch panel, touching the pointer will absorb ultrasonic waves and cause attenuation, so the signal when receiving is different from when it is not operating. The controller compares the attenuation before and after use and calculates the precise position. Its advantages are good fire resistance, waterproof, anti-fouling, and poor scratch resistance, suitable for large sizes, but high in price. Generally used in the use of Kiosk or automatic ticket vending machines. Galanz Microwave Oven Panel Membrane Switch 3. Capacitive The capacitive touch panel uses the capacitance change produced by the electrostatic combination between the arranged transparent electrodes and the human body to detect its coordinates from the induced current generated. The sensing principle uses voltage to act on the four corners of the screen's sensing area and form With a fixed electric field, when a finger touches the screen, the electric field can cause a current to be generated. The contact position can be calculated according to the ratio of the current to the four corners by the controller. However, the capacitive type must overcome the influence of noise generated by the pointer object due to static electricity, so it is more difficult to design the circuit and structure. When subjected to contact pressure, the position can be calculated according to the current ratio. 4. Resistive The resistive touch panel mainly consists of two upper and lower ITO conductive layers, spacers, and electrodes. It uses ITO glass as the substrate, and a layer of ITO is superimposed on Support Panels And Subpanels Membrane Switch Film, with Spacer supports scattered in the middle, so that the upper and lower plates will not be conductive due to the close proximity, and the edges are printed with silver electrodes to provide voltage. When in use, pressure is used to make the upper and lower electrodes conduct, and the controller detects the change in the panel voltage to calculate the contact point position for input. The advantage is that it is waterproof, antifouling, and cheap, but the disadvantage is that it has poor scratch resistance and fire resistance. Generally used in the use of small and medium-sized portable handheld devices.

The choice of the type of China 5MM Force Pressure Sensor mainly depends on the type of force measurement and the installation space, to ensure proper installation and safe and reliable force measurement. On the other hand, the manufacturer`s recommendations must be considered. For sensor manufacturers, it generally specifies the force of the sensor. Conditions, performance indicators, installation forms, structural forms, materials of elastomers, etc., such as aluminum alloy cantilever beam sensors are suitable for electronic price calculation scales, platform scales, case scales, etc., steel cantilever beam sensors are suitable for electronic belt scales, sorting scales, etc. Etc., steel bridge sensors are suitable for railway scales, truck scales, etc., and column sensors are suitable for truck scales, dynamic railway scales, and large-tonnage hopper scales. Force sensors are mainly used in various electronic weighing instruments, industrial control fields, online control, installation overload alarms, material testing machines and other fields, such as automobiles, medical treatments, robots, electronics, mechanical equipment, automation equipment, etc., such as: button feel test Instrument, hot and cold press pressure detection, robot hand grip and other small installation space force value detection areas. The China Force Pressure Sensor is actually a device that converts the quality signal into a measurable signal output device. The actual working environment of the sensor must first be considered when using the sensor. This is very important for the correct selection of the sensor. It is related to whether the sensor is normal. Work, its safety and service life, and even the reliability and safety of the entire weighing instrument. Under normal circumstances, high temperature environment causes problems such as melting of coating materials, opening of solder joints, and structural changes in the internal stress of the elastomer. Dust and humidity can cause short-circuit effects on the sensor. In a highly corrosive environment, it will cause sensor elastomers. Damaged or short-circuit phenomenon, electromagnetic field will produce interference to the sensor output, we must select the corresponding sensor to meet the necessary weighing requirements under the corresponding environmental factors.

IP65 Waterproof Membrane Switch is a kind of switch that is resistant to environment. Anti-environment means being able to resist harsh external environment, such as dirt, temperature and moisture. Water is lethal to commodities, especially electronic commodities. This kind of lethality is like dripping water through rocks. If it can't block the harm caused by water, it will reduce the impact of water on the lifespan of commodities. Harsh Environment Membrane Switch is a kind of switch that is resistant to environment. Anti-environment means being able to resist harsh external environment, such as dirt, temperature and moisture. Water is lethal to commodities, especially electronic commodities. This kind of lethality is like dripping water through rocks. If it can't block the harm caused by water, it will reduce the impact of water on the lifespan of commodities. Membrane switch is not afraid of water, that is, it can reduce the impact of water on the life of the switch to a certain extent. In the face of strong water, the survival factor of the switch is related to its structure, manufacturing materials and manufacturing properties. Membrane key switch belongs to a kind of sealed structure, and the sealing property must prevent foreign impurities from invading to a certain extent. The materials of the switch manufacturing are all waterproof materials and are guaranteed brand materials, so they can still maintain even when exposed to a small amount of moisture. The original life span. Regarding the manufacturing nature of the switch, it is to change the traditional switch, so that the existing switch can play a greater effect in the whole product. As far as the membrane switch is concerned, it has many different functions from the usual switch, and it can also be used as a complete product. Appearance maintenance The whole product is protected from external hazards. The life span of the LED Backlighting Membrane Switch can be as high as 1 million times. There is no need to worry too much about the harm caused by external influences. Waterproof is only one of the main functions of the membrane switch.

Membrane switches are commonly used in some precision instruments and instruments with high requirements for appearance. This kind of switch has been widely used in many fields by virtue of its high-quality performance. It has many advantages at will, but the selection process is also very difficult for people who don't understand this kind of switch. The following selection techniques are hoped to be helpful to everyone. First of all, clarify the use environment of the switch. In fact, Harsh Environment Membrane Switch is a general term for a type of switch. There are many different types of switches in this type of switch, such as flat type, film convex touch and so on. Different types of switches have their own advantages and disadvantages, and their suitable use environments are also different. . In the actual selection, the application environment should be considered. Secondly, consider the switch price cost. In many fields, the switch is only a part of the device, but the price of the switch will affect the price of the entire device. If the price is too high, the cost of the device will be affected. Therefore, the price factor should not be ignored when choosing, but it must be considered in many ways and choose a switch with a higher cost performance. Such as Tactile Feedback Membrane Switch and Copper Flex Membrane Switches. As a membrane switch widely used in electrical appliances and precision instruments, you must pay attention to the above two points when choosing, so that you can ensure that you can choose products with high quality and high cost performance.

The composition of gold and silver ink and how is it applied in the manufacture of film buttons? Like other inks, gold and silver inks are mainly composed of two parts: pigments and binders. Simply put, golden ink is blended with gold powder and gold blending oil, and silver ink is blended with aluminum powder and silver blending oil. 1. Pigment The pigment in golden ink is gold powder, which is actually a powder made of copper and zinc alloy. The content of zinc in gold powder is generally about 8% to 30%, among which the zinc content is between 8% and 12%. The color of gold ink is reddish, and it is customarily called red gold. The color of gold ink with zinc content between 20% and 30% is more blue. It is generally called cyan, which is between red gold and cyan gold. It is green, red and gold. In Itema membrane switch printing, 800 mesh gold powder is generally used for the deployment of gold ink, and the surface of the gold powder particles are mostly covered with surfactants, which can be well combined with the resin binder. Silver powder is actually aluminum powder, which is composed of 65% flake aluminum powder and 35% volatile hydrocarbon solvents. Adhseive To LSE Plastics Membrane Switch. Aluminum powder pigment has a small specific gravity and is easy to float in liquid. What is used in printing silver ink is the floating silver powder that has the ability to float in the binder. Silver ink generally uses 400-1000 mesh silver powder. If silver ink is printed on a large area, a lower mesh silver powder can be used. For example, 400 mesh silver powder is used to prepare silver ink ink, which has a higher metallic luster after printing. Printed Circuit Board Membrane Switch. 2, the link material The bonding material used in the gold and silver inks widely used in the printing of film key panels is a special ink-adjustable oil, generally called gold-adjusted oil or silver-adjusted oil, and the main components are oil, resin, and organic solvent. Supplementary materials. The binding material of printing ink should meet the following conditions: (1) The transparency must be high, and it cannot affect the hue of gold and silver ink. (2) It must have enough viscosity to combine well with gold or silver powder. (3) Gold or silver oil should also have quick-drying and fast-fixing properties to prevent the back of the gold ink or silver ink membrane switch panel from sticking to the back. (4) The acidity of gold or silver oil should be low, otherwise it will cause chemical reaction of gold powder or silver powder. 3. Additives Printed ESD Shielding Membrane Switch. In winter, adding a small amount of red dry oil to the gold ink can speed up the drying speed; adding a small amount of bright paste or transparent yellow to the metal can enhance the ink affinity and transfer ability of the gold ink; adding a small amount of bright paste to the gold ink can improve the drying speed While diluting the gold ink, it improves the brightness and viscosity, reduces the accumulation of gold ink and improves the fluidity. Adding stearic acid amide surfactant when adjusting the ink can make the gold powder fully wet, disperse and float in the binder. Reduce the phenomenon of paste and pile-up in the process of ink transfer. Gold ink and silver ink are widely used in the manufacture of membrane keys. They can effectively improve the product grade of membrane keys, enhance aesthetics, and improve artistic and decorative effects. Especially in consumer electronics and household appliances, gold ink and silver ink play an irreplaceable role.

The Light Emitting Diodes Membrane Switch sounds quite professional. In fact, the popular one is the panel button. The name is familiar. Many equipment control panels use membrane switches, which are widely used in electronic communication, electronic measurement instruments, industrial control, and medical equipment. , The automotive industry, smart toys, household appliances and other fields. Next, we will introduce the principles and characteristics of membrane switches and other related knowledge. Principle of light-emitting membrane switch The Fiber Optic Lighting Membrane Switch is a multi-layer structure (plane) type (non-locking) key switch composed of a certain elastic insulating material layer, and an integrated circuit. Buttons, indicating elements, instrument panel and other functions are integrated. The action of the Electroluminescent Lighting Membrane Switch is only realized by the vertical movement of the elastic membrane. Although the elastic membrane has undergone a million peristaltic movements, and the amplitude of the peristaltic movement is very small, only 0.1-0.3MM, and the material selection is reasonable, so the membrane material It can withstand a long life of more than one million times without deformation, which determines the durability of the membrane switch.

Many people don't know what a membrane switch is, or even if they know some, they think it is rare in daily life. In fact, the use of Tactile Feedback Membrane Switch has been closely related to our daily lives, and membrane switches have become one of the indispensable applications of smart phones. In order to facilitate everyone's knowledge and understanding of membrane switches, we will take you to learn about smart phones today, because this is common and very common. Smart phones do not have bumpy buttons. The second is touch buttons. This is the category of membrane switches. The application of Silicone Rubber Keypads Membrane Switches should be household appliances at most, because of its micro switch characteristics, small size and light weight. Many applications that we touch every day, such as TV buttons, DVD buttons, computer buttons, CD-ROM buttons, keyboard buttons, monitor buttons, lighting buttons, etc. Digital Resistive Touch Membrane Switch have a wide range of applications under normal circumstances. Not only can they meet the requirements of most membrane switch panels, but the high light transmittance of glossy PCs can also meet the requirements of liquid crystal display windows. Its hardness and the greatest strength among thermoplastics, low water absorption, wear resistance, friction resistance, and high dimensional stability. The tensile strength is also very good, much higher than PC and PVC. The reason for the low price is that the surface is difficult to process into a matte type, so the high price of textured PET is the most ideal material for making membrane switch circuits.
