ABSTRACT:
An electrical power tap is provided with at least one shutter mechanism to block spurious insertion of a foreign object through one blade slot short of the power circuit contacts of an adjacent pair of plug receptacles. This mechanism includes a pair slides supported for independent movement between closed-latched and open positions. Access to the contacts of either power tap plug receptacle requires that its slide first be unlatched by a blade penetrating one slot and then cammed to the open position by another blade penetrating the other slot, as occurs incident to the insertion of a standard electrical plug.
