ABSTRACT:
A safety plate for electrical outlets includes a cover plate having apertures therein for receiving the prongs of an electrical plug. A pair of slidable panels also having apertures for the prongs of a plug, are mounted to the back of the cover plate, and are held in place by a back plate. The back plate has a pair of holes therethrough corresponding to the receptacles of an electrical wall outlet, so as to allow a close fit between the receptacles and the slidable panels. A spring biases the panels so as to misalign the panel apertures with the cover plate apertures, such that there is no direct opening between the cover plate apertures and the receptacle apertures. A tab projects from each slidable panel through an opening in the side of the cover plate, to allow the user to push each independent panel against the bias of the spring and align the panel apertures with the cover plate apertures, and thereby allow insertion of an electrical plug therethrough into the receptacle apertures. A gasket along the back perimeter of the cover plate seals any air leaks.
