Keypad construction with a PCB
By using a direct combination of keypad fields with PCBs, a supporting plate can easily be dispensed with. In this case, the thickness of the PCB material (FR4 etc.) is selected so as to ensure that the stability is comparable with that of a metal supporting plate. Threaded bolts can be fitted, and openings or relief milling are possible. The decor layer is then fitted to the front in the same way as a conventional keypad. Using this method results in considerable savings for our customers.
