Abstract
An improved switch for entering a key code includes a plurality of moving contact members all molded together into a single membrane. Each of the moving contact members moves within a hole in a housing. The housing is connected to a base with a snap connection. A circuit board and the membrane are sandwiched between the base and housing. A sealing lip on the membrane is deformed against the housing to provide a water tight seal around the circumference of the housing. Wires extend from the circuit board through holes in the base, and grommets surround the wire sealing the holes. LED's are provided on the circuit board to backlight the moving contact members.
