Membrane keypads
Membrane keypads are low-power sensitive element. They are perfectly fit as control elements for microprocessor electronics. Membrane keypads can be based on a printed circuit board or on a polyester film.
Advantages of membrane keypads:
- thin, easy to clean
- dust-, moisture- and oil-proof
- sealed
- attractive appearance
- possibility to use various designs and colors
- low price
- Keypads with raised buttons
- Tactile keypads
- Keypads with FPC / Connector
- Membrane keypads with LED backlight
- Faceplates and overlays
appliance
The control panel can be made with different circuits:
- Fully membrane keypad (electrical circuit is made on film)
- FPC keypad
- Rigid PCB keyboard
