Abstract
An electrical receptacle is provided with a shutter mechanism to block spurious insertion of a foreign object through one of the receptacle slots short of the receptacle power circuit contacts. This mechanism includes either one or two slides supported for movement between closed-latched and open positions. Access to the contacts requires the slides first be unlatched by a blade penetrating one receptacle slot and then cammed to open positions by another blade penetrating the other receptacle slot, as occurs incident to the insertion of a standard electrical plug into the receptacle.
