ABSTRACT:
A safety socket assembly comprising a non-conductive housing containing a conductive pair of prong sheaths each having a facing aperture on the inside portion thereof and one of the prong sheaths having a slidable contact thereon. A pair of electrical terminals are provided one of which is connectable with its corresponding prong sheath only by means of the slidable contact. A self-locking displaceable peg connected to the slidable contact is situated between the prong sheaths and is locked in position by locking means which extend into the apertures in the prong sheath. The prongs of a plug inserted into the prong sheaths release the locking means allowing the plug to move the peg and slidable contact backwardly until the contact comes into contact with its terminal thereby energizing the socket. Removal of the plug causes the peg and slidable contact to move forwardly to the locking position thereby de-energizing the socket.
