ABSTRACT:
A tamper-resistant electrical receptacle disclosed herein includes a cover assembly having at least one pair of apertures, a cover, and at least one slider that rests in the cover behind one pair of the apertures. The slider is held in a first position where it covers both apertures such that an object is blocked from entrance in either aperture and, thereby, blocked from accessing either receptacle terminal formed in the base assembly connected to the cover assembly. This first position is maintained until prongs are substantially inserted simultaneously into the apertures causing the slider to move into a second position where the prongs are enabled to pass through the apertures, engaging the receptacle terminals. After the prongs are removed from the receptacle terminals, the slider automatically retracts to the first position. When only one aperture is probed by an object, however, the slider remains confined in the first position.
