ABSTRACT:
A rotary switch for use with electrical circuits and including a housing having a cavity therein for receiving a rotatable disc. The housing supports a plurality of spaced apart electrical terminals each independently connected to an electric circuit and also supports a plurality of opposed resilient contacts selectively engagable with the electrical terminals. The rotor includes opposed planar surfaces, one of the surfaces parallel to and adjacent the resilient contacts, the rotor surface supporting a plurality of cams projecting from the surface and functional upon rotation of the rotor to force selected ones of the resilient contacts into engagement with the terminals to provide an electrical bridge between pairs of the electrical terminals. The rotary switch rotor can include cam members on both of its opposite surfaces and the housings are constructed such that they can be stacked.
