ABSTRACT:
An electrical receptacle having at least one plug-receiving receptacle socket comprising a two-piece housing having contact fingers which are spring biased against a center post of the housing by a coil spring. The coil spring is interposed between the ends of a flexible shunt member which electrically interconnects the contact finger with the bus-bar member, the bus-bar member having suitable wire-connecting screws. Thus, the load force on the contact fingers prevents accidental removal of a typical two-prong electrical plug when positioned in the receptacle socket.
