ABSTRACT:
A multi-contact rotary switch in which arcuate cam lobes on the planar faces of a rotatable disc-shaped cam rotor selectively engage a plurality of switch elements. Each switch element is attached to one of two switch blocks positioned adjacent to either cam rotor face. Slots in the switch blocks laterally confine the switch elements to preserve their alignment. A raised annular bearing on the cam rotor face maintains the position of the cam rotor relative to the switch blocks. Terminal extensions from the switch elements extend perpendicular to and away from the planar faces of the cam rotor.
