Conductive rubber keypads

Conductive rubber keypads is compression-molded silicone rubber actuators with or without a conductor on the bottom of each key; and offer an alternative look and feel to more common polyester or polycarbonate overlays. They, too, are always used in conjunction with a printed circuit board or flexible circuit. It is the flexible circuit or PCB that provides the circuitry traces while the rubber keypad acts as the overlay and shorting pad.
