ABSTRACT:
A shielded contact slide switch is disclosed having two plastic dielectric parts, one of which parts houses the fixed electrical contacts, and the other of which parts moves relative to it and houses the bridging contact. Mating surfaces of the two parts are designed to seal off the contacts from environmental effects, and the actuator is defined on the movable part and has projecting portions to overlie a cavity or recess in the fixed part housing the fixed contacts regardless of switch position. The movable part also has projecting ears extending laterally into the side walls of the fixed part to restrict the sliding part to movement as dictated by the relative locations for the fixed and movable bridging contact. A spring return single pole double throw switch is disclosed but in place of the return spring another pole might be provided.
