Non-tactile membrane switch
The buttons of the non-tactile membrane switch are not embossed or printed only with ink on the button frame. The realization of the function lies in the combination of the power-on point on the panel or the power-on point of the upper circuit and the power-on point of the lower circuit to form a line conduction. The main difference from the tactile membrane switch is that when the button of the graphic overlay is pressed, there will be no obvious sound and no tactile feedback is provided. The main way to judge the realization of the function is whether there is an optical change in the LED or LCD window. You can also use LED backlight technology to determine whether the function is realized by judging whether the button or font is lit.
Working Principle of flat membrane switch
The basic working principle of the membrane switch is as follows: When the membrane panel is not pressed, the membrane switch is in a normal state, with its upper and lower contacts in a disconnected state, and the isolation layer isolates the upper and lower circuits; when the panel is pressed, the contacts of the upper circuit deform downward, It coincides with the lower line and makes the line conductive.The conductive line sends a signal to the external connection instrument (substrate) to realize its corresponding function; when the finger is released, the upper circuit contact rebounds back and the circuit is disconnected. The loop triggers a signal.

Waterproof membrane switch factory construction
Membrane switches are two main structures
- Raised structure:
The switch button is slightly raised, slightly higher than the panel, forming a 3D membrane switch. The convex is helpful to stimulate the operator’s sensitive touch, to help the operator accurately determine the position of the button, and to improve the recognition speed. The convex membrane switch can be designed into a variety, improving the decorative effect of the product and achieving a perfect appearance.
- Flat structure:
A flat structure was common in the initial stage of the membrane switch. The buttons on the membrane switch simply use color to express position, shape, and size. The accuracy of the operation can only be identified by the operator’s vision, and there is no appropriate feedback information to indicate whether the fingers press the effective range of the switch to make it work, thus affecting the confidence of the whole machine monitoring and control, and the speed of operation as well.
Membrane Switch Metal Dome Tactile Type
waterproof membrane switch supplier Materials Selection PC/PET
Membrane Switch and Tacitle Panel
Membrane panel is a type of HMI, in which the structure is generally PET, PC as the base material, DT, Nitto, or 3M as the adhesive material to assemble them. A membrane switch and panel is a kind of HMI with more prominent performance and lower prices.
The membrane touch panel is the operating system on many electronic controllers, medical accessories, and agricultural products, and it is also the first interface. Color matching and design are particularly important. Fortunately, as one of the most professional membrane switch manufacturers, Shanyo’s engineers and designers are very good at this type of membrane control panel. At the same time, we will strictly review whether the customer’s drawings and ideas can be realized.
Membrane Keyboard Switch Materials Selection PC/PET
1. Panel material:
Ils sont généralement divisés en deux catégories : PC (polycarbonate) et PET (polyester).
There are bright and matte surfaces (fine sand, medium sand, coarse sand) Commonly used thicknesses are 0.125, 0.175, 0.25mm. Special treatment includes HP series (such as HP40, HP60 and HP92S, etc.) Advantages of PC material: good ink adhesion. Disadvantages of PC material: poor corrosion resistance, difficult to use in outdoor products. Generally, those with Windows use a glossy PC, and those without Window use a matte PC. Matte PC is scratch-resistant.
There are bright and matte surfaces:
Matte:
Autotype (thickness 0.15mm and 0.20mm) Kimoto (thickness 0.125mm and 0.188mm)
Bright side: Autotype (thickness is 0.18mm and 0.25mm) Izaya (thickness is 0.125mm and 0.188mm) The above PET is treated PET.Autotype PET has excellent adhesion to ink. Its material molecular structure has a combination of softness and rigidity and has a good appearance and dimensional stability.
Avantages des matériaux en PET : bonne résistance à la corrosion, résistance aux environnements difficiles, résistance à la flexion, bonne résistance à la température et bonne élasticité.
Disadvantages of PET materials: Compared with PC materials, the adhesion of ink is slightly worse.
Matte PET is scratch-resistant.
Line materials:
Le PET présente une bonne isolation et une bonne résistance à la chaleur, une résistance mécanique élevée, une transparence, une résistance particulière à la flexion et une grande élasticité. Par conséquent, le PET est un matériau idéal pour la fabrication de circuits de commutateurs à membrane.
- Generally, untreated PET is used;
- L'épaisseur est de 0,075, 0,1, 0,125 mm.
- It is generally appropriate to choose 0.125mm. If it is too thick, the response will be slow and the switch sensitivity will be poor. If it is too thin, it will have insufficient elasticity and will not be conducive to the plug-in of the lead wire end.
Key piece (isolation layer) material:
Generally 0.1, 0.15, 0.20, and 0.25mm thick double-sided tape.
The thickness of the key sheet depends on the size and shape of the key, which is directly related to the operating pressure of the membrane switch and the sensitivity and reliability of the switch. Therefore, the size of the keyhole should be consistent with the size of the key pattern. When the size of the keyhole is larger, the thickness of the keysheet will also increase.
Membrane Push Button Switches Material Used In The Circuit Layer
Membrane Key Switch Material Used In The Circuit Layer
The base material of the circuit should be polyester(polyethylene phthalate) Film (Polyester referred to as PET).
It has good insulation and heat resistance, high mechanical strength, transparency, and airtightness, especially folding resistance and high elasticity.
Membrane Switch China Thickness of The Plastic
The thickness of the plastic substrate is 0.25mm or below and is called a membrane. It is mainly used as the panel layer of the membrane switch. Various indicative patterns and text are printed on the back to indicate the operation area of the corresponding key switch. Depending on the size of the button, the material is thick, the touch force is increased, and the response is slow; the material is too thin, the feel is poor when touched, and the rebound is not obvious. Thickness above 0.25mm is called a plate, which is not suitable for three-dimensional key forming. It can be used as an indicative sign panel in the keyless operation area, and can also be used as a lining for membrane switches to increase its hardness.
Custom Membrane Switch Circuit Ventilation Slot
- For the key sheet, in addition to punching the key sheet hole, it is also necessary to process the air guide groove, that is, the ventilation groove. The function of the ventilation groove is to conduct the air sealed in the membrane switch.
- The design of the ventilation slot is not arbitrary. It should be based on the relationship between adjacent key positions and the amount of air absorbed by the keyhole to determine the direction of the shunt. This way, we can better use aerodynamic force to force the relevant key positions to reliably separate. The ventilation slot is generally 2mm wide, and there are no less than 3 keyholes connected to the ventilation slots. 4-6 key connections have better effect. If the number of keys is less than 3, the key ventilation slot must be ventilated to the outside. It is ventilated to the outside and the buttons feel good to the touch.
The ventilation slot is generally 2mm wide, and there are no less than 3 keyholes connected to the ventilation slots, and 4-6 key connections provide better results. If the number of keys is less than 3, the key ventilation slot must be ventilated to the outside. It is ventilated to the outside and the buttons feel good to the touch. - La largeur minimale des lignes est de 0,3 mm, généralement de 0,8 à 1,0 mm.
- Le tracé de la ligne doit généralement se situer à moins de 2 mm d'un côté de la forme de la ligne.
- La forme du circuit est généralement 0,5 mm plus petite d'un côté que la forme du panneau (facile à assembler).
- La zone des doigts du fil conducteur doit être recouverte de pâte d'argent et de pâte de carbone.
La pâte de carbone est une pâte conductrice non métallique qui ne se combine pas avec l'oxygène de l'air et peut protéger la pâte d'argent sous-jacente de l'oxydation. Le carbone présente également une grande résistance à l'usure, ce qui est pratique pour brancher et débrancher les fils et les bornes de connexion.
Wholesale Membrane Switch Company Inks
It is divided into conductive ink, insulating ink, matte ink, and color ink.
- Conductive ink: silver paste, carbon paste, and silver-carbon mixed paste ;
- Insulating ink: plays an insulating role and is generally used for jumper insulation and entire surface insulation;
- Matting ink: window matting, panel matting;
- Colored ink: Due to different materials, the inks used are also different, including inks for PC materials and inks for PET materials.
Membrane Switch Dome Type
Shanyo can provide various types of custom membrane switches embossed keys, as shown in the picture below.
The default is circular relief (1st from left). If you need other types, please indicate it in the remarks or drawings when custom.
Membrane Switch with Metal Dome Key
This type of membrane switch uses a metal dome as the upper circuit layer of the switch. By pressing the key, the metal dome central point will connect the lower circuit, and then trigger with a signal. Metal dome is usually made of stainless steel, which is flexible and can be pressed more than one million times.The keys of the metal shrapnel have a good button tactile and provide good tactile feedback to the operator. Shanyo uses a stainless steel cross dome and is available in specifications of 8.4mm, 10mm, 12mm, 14mm, and 16mm. The metal dome size of 10mm – 12mm is generally recommended, which is more suitable for the actual finger press.
Membrane Switch with LED
This type of membrane switch can be installed with LEDs inside. When the corresponding button is pressed, the LED will light up and be used only as the operating area of the switch. The LED light is welded on the circuit under the membrane switch to assemble it as a whole. The LED light window is often bumped. This type of product is mainly used for the function keyboard of the industrial control equipment of the man-machine interface. Shanyo this product can be welded with LED lights of various colors according to customer needs.
Flat Membrane switch
Neither the upper circuit silver pad nor the circuit layer is embossed. The entire panel layer is flat, the keys are insensitive to touch, and the service life of the keys is more than 2,000,000 times. It can be used as a functional membrane switch for industrial control equipment and household appliances.
Membrane Switch with Electrostatic Shield
Membrane switch with an Electrostatic Shield is seated up electrostatic protection components (ESD) inside the device, The main principle is to use electromagnetic shielding to shield space from electromagnetic interference, thereby reducing and eliminating electromagnetic interference from space. Generally, it is used in fields and products that have high requirements for electromagnetic interference EMI and EMC, such as laboratory equipment, scientific research equipment, and military products. The membrane switch used in the above will use a shielded electrostatic membrane switch, which has complicated art and high cost, and it is especially suitable for products with requirements for anti-electromagnetic interference performance and low-cost requirements. Features:It has anti-static protection for product devices Reduce the damage of static electricity of surrounding devices
Interrupteur à membrane étanche
The waterproof membrane switch can be used in rainy or humid environments with a waterproof and moisture proof effect. Shanyo’s unique waterproof technology with 3M300LSE adhesive, the waterproof grade can reach IP67. This product is more used in the kitchen medical, and outdoor devices.
Plug-in-Card Membrane Switch
Plug-in-Card membrane switch, It will design a colorless transparent window in the graphic overlay, If the bottom of the graphic overlay is isolated, then it is ok to plug in the cards from the card slots on the edge side. The membrane switch is the main body, the cards can be designed in various ways, and the cards can be replaced according to actual use, which can be more flexibly used. This type of membrane switch is mainly suitable for supermarket electronic weighing devices.
In this kind, the Membrane switches can be used repeatedly. Only the graphics and text of the card need to be changed. Shanyo designs key content, color, effect, etc. according to customer needs, The Plug-in-Card Membrane Switch can only change the design of the cards in the future, it can be used more widely.
Membrane Switch with Die-pressing Key
This type of membrane switch uses silver paste as the upper circuit layer of the switch. By pressing, the center of the silver paste point is connected to the lower circuit to achieve conduction and trigger signals. Through “molding”, the silver paste plate of the upper circuit button is pressed into a certain dome shape with a mold, and a certain elasticity is generated, so that when the button is pressed, it can rebound and the circuit can be opened or closed.
It’s also noticeable enough to feel like the switch is off. The bumps of silver paste require the use of molds, especially for batch orders. Customized bump molds can greatly improve production efficiency and product quality stability.
The stamped silver pad can be designed from 5mm to 11mm, and the recommended size is 8mm to 10mm. The button size will be more suitable for finger pressing.
