ABSTRACT:
A safety electrical plug has two-part prongs. Each prong has a distal portion that is electrically insulated and a proximal portion that is conductive. Substantially full insertion of the plug into a receptacle is required to establish an electrical connection between the prongs and the receptacle contacts. This limits the chance of electric shocking by human or animal engagement of the exposed portions of the prongs subsequent to only partial insertion of the plug into the receptacle, and signals the partially-inserted condition when subsequent attempts to operate an electrical appliance connected to the plug fails. The conductive prong portions may be inserts in a nonconductive base, or be the entire proximal portions, which may optionally mount a strip of non-conductive material along their edges.
