ABSTRACT:
A safety improvement in cover plates for electrical outlets. A cover plate for electrical outlets having sets of a spring-loaded sliding traverse plates which shift to open and close electrical wall outlets used in residential, commercial, and industrial locations. The sliding spring-loaded traverse plates being positioned between sets of tracks which are laterally parallel to outlet holes located in the cover plate, and each traverse plate having a hole which may be manually positioned to be in line with outlet holes located in the cover plate. When holes in the traverse plates and the cover plates are in line, the prongs of male terminals may be inserted into the female recepticle. When the male terminal is removed from the female recepticle, the traverse plates automatically spring into a closed positions thereby shielding the said female recepticle, which thereby prevents a child from being electricuted by sticking a small metal object into female electrical outlets.
