Abstract
A contact assembly for alternating current electrical receptacles is disclosed in which electricity is not applied to the pins of a mating electrical plug until the plug is inserted substantially entirely into the receptacle assembly. The wiper contacts which engage the pin when it is pushed into the receptacle are initially not connected to the electrical source. When the tip of the pins engage the bottom of the receptacle housing, it engages a separate contact assembly which makes electrical connection to the electrical source only after the pins are inserted almost entirely into the receptacle. The exposed portion of the pins of the electrical plug are therefore not energized until the plug is almost fully inserted, thus preventing inadvertent touching of the exposed pins and the resultant electrical shock.
