ABSTRACT:
A rotary switch having a housing carrying a plurality of terminals which may be assembled within the housing in various combinations to give the switch different operating characteristics, with the terminals providing a circular array of spaced switch contacts arranged in a plane normal to the switch axis, has a rotary carrier mounting at least one disc contactor facing the array of contacts, the carrier being biased toward the plane of the contacts to urge the contactor into circuit closing relation with the contacts. A switch base snaps together with the terminal housing to enclose the carrier and an actuator, preferably in the form of a key lock tumbler plug, extends through the base and drivingly engages with the carrier to effect rotation of the contractor relative to the contacts and thereby operate the switch.
