Membrane keypads
User-friendly control panels that can be used in various areas of application. These panels have a long useful life and are reliable.
Metagra-Industry also offers you various solutions with regard to design:
- flat keys, polydome, metaldome
- round, flat or edge embossing
- incorporated LEDs: with or without embossing on the front
- design of the front in accordance with your concept and our possibilities
- connector
- mounted on support plate
Switching occurs by means of printed contacts or metal domes ( gilt mechanical switch elements of various sizes and switching actuation force).
Only high-quality polyesters are used as the basic material both for the front and for the circuit. The membrane circuit is protected against oxidation: the printing is finished with special silver, carbon and insulation. An additional protective layer of carbon is applied at the connection and the switch elements.
Shielding can also be integrated.
Special applications:
- protective film
- keyboards in combination with PCBs
- Plastic fiber (LED driven) backlighting
