Mechanical Membrane Switch
Membrane Switch, also known as Touch-type Keyboard & Membrane Keyboard.

Membrane Keyboard is
a overall sealed structure by using plane multi-layer combination. Membrane Keypad is a kind of new electronic components with the technology of light, mechanic and electronics which seal together by the key switch, panel, marking, symbol display and liner.It is a set of key functions, indicating components, instrument panel,consisting of the panel, top circuit, isolation layer, floor circuit. When you press the membrane switch, the contact on the circuit downward deformation, contact with the floor circuit plate conduction; When releasing finger, the top circuit contacts bounce back, the circuit is disconnected, the circuit triggers a signal. 
Membrane Keyboard Panel is a kind of plastic which uses a rigid or flexible printed circuit board as the substrate, a feel or no touch keys on installation, and then covered with color printing decorative patterns.The switch circuit and the machine can be connected by welding or plug.

Membrane Switch with good waterproof, dustproof, anti-oil, anti-harmful gas erosion, stable and reliable performance, light weight, small size, long life, easy assembly and the panel can be washed without damage characters, rich colors, nice.
Membrane Switch is a change in the appearance of fundamental structure of electronics, it can replace the conventional discrete components of the keys , more reliable implementation of the task of the operating system.

There are three standard methods for illuminating Membrane Switch: Light Emitting Diodes(LE Ds), Opticals Fibers ,   and Electroluminescent Lamps   (EL) .

PVC: shiny side; stability for acid, alkali and salt at room temperature. Good wear resistance, self-extinguishing flame, muffler shock, electrical insulation. Thermal stability is poor. It is usually used in low common signs, panels.
PC: shiny side; high transmittance, low water absorption, good dimensional stability, bending, tensile, excellent compressive strength, heat resistance, cold resistance, electricity Insulation and good resistance to atmospheric aging. Poor chemical resistance, and fatigue resistance, easy to produce stress open crack,
PET: shiny side; good chemical resistance, insoluble in common organic solvents, not alkali resistance. Has excellent mechanical properties,electeical properties , rigidity, hardness and the largest thermoplastic strength and toughness, low water absorption, excellent wear resistance, friction resistance, high dimensional stability . Tensile strength can be comparable with the aluminum film, much higher than the PC, PVC. The PET has texture.It is more expensive. PET is the best substrate in producing membrane switching circuit . One of the textured PET is suitable for products which has higher requirement on products surface or have a liquid crystal display window.


It depends on the application requirement, a membrane switch can consist of as few as 4 layers, as many as many as layers.

1.the panel layer
2.the surface layer
3.the upper and lower control circuit
4.the folder layer
5.the back of the rubber layer
