Membrane Keypads  Manufacturers, Traders, Suppliers

Features and Benefits of Membrane Switches:
1) Very thin and light can be assembled on many different materials surface, like plastic, metal, rubber etc.
2) The overlay material usually are PET and PC. They are easy clean and sterilized;
3) Waterproof and anti-UV for outdoor application, and also can use antifungal material for medical special application;
4) Multicolored (can be silk screen printed or digital printed graphic);
5) Economical and cost saving compared with touchscreen panels;
6) Can be customized to any shapes to fit into your design;
7) Low tool cost and short prototype manufacturing;
8) The circuit can be assembled with LEDs, resistors, capacitors, connector etc. electronic components;
9) Flexible and diverse types of keypad assemblies: assembled with rubber, PMMA/PC/SS Panel/Al Panel, PCB, FPC etc.
10) Can be friendly interface and also can be designed backlit to convenient of the night or dark environment using;
11) Flexible can be used one curved surface;
12) Low cost and long life of buttons, can be more than 1,0000,000 times;
