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:

appliance

The control panel can be made with different circuits:

  • Fully membrane keypad (electrical circuit is made on film)
  • FPC keypad
  • Rigid PCB keyboard
The junction of the PCB with external blocks is mounted by means of a flat cable or flexible wires.
