A switch assembly for providing a push-pull, double pole, switch action has molded cylindrical first and second housing portions having first and second pairs of electrically isolated contact terminals fixedly mounted therein in electrical isolation and extending outwardly from the housing portions which are formed with a central aperture therethrough. A switch operating plunger having a cam located intermediate the ends of the plunger is positioned within the housing, the ends of the plunger extending outwardly through the central aperture of the housing portions. The plunger and cam are mounted for limited axial reciprocating movement within the housing portions between a first and second position. A resilient conductive bridge contactor is positioned within the housing and is movable by the cam on the plunger in a direction opposite the movement of the plunger to complete the electrical connection between the first pair of contacts when the plunger is in one position and to complete the electrical connection between the second pair of contacts when the plunger is in the second position. Means secure the housing portions together to provide a unitary housing. One embodiment of the bridge contactor is particularly adapted for miniaturization of the entire switch assembly. The plunger is rotatable within the housing. One end of the plunger is adapted for coupling to external rotary drive means.
