ABSTRACT:
An electrical rotary switch having a housing formed of an electrically insulative material and including a plurality of fixed electrically conductive contacts therein. A rotatable contact is arranged to be rotated into a plurality of positions and includes electrically conductive means to electrically interconnect selected ones of the fixed contacts depending upon the rotational position of the contactor. A detent mechanism is located in the housing and comprises a generally planar, frame-like plate formed of a resilient material and having an opposed pair of elongated arms extending generally parallel to each other and interconnected adjacent their respective ends by cantilever arms. The cantilever arms form tapering cam surfaces which are adapted to engage diametrically opposed recesses in the rotatable contactor to establish the various rotational positions of the rotatable contactor. The decent plate is located within a recess in the housing. The housing also includes plurality of electrically conductive insulation displacement connectors electrically connected to the fixed contacts. At least one break-away block is provided in the housing and adjacent the insulation displacement connectors. The block is arranged to be displaced by a force provided thereto to cause it to break away from the housing to move into a position carrying the electrically conductive wires into the insulation displacement connectors so that electrical continuity is established therebetween. Both the block and the housing include recess portions which cooperate with each other to provide passages through which the electrical wires extend into the housing once connection is effected.
