Visual indicator electrical plug-type surge protector and systems

A visual indicator electrical plug surge protector which comprises:

• (a) a molded polymeric plug body comprising a generally transparent polymer and a thin layer of said polymer extends over the outward surface of the varistor means;
• (b) the plug body having on one face a grounding prong and a pair of parallel male electrical prongs, the grounding prong and the electrical prongs adapted to be inserted into an electrical output plug;
• (c) the plug body having on an other face a female grounding plug inlet and pair of female electrical plug inlets in electrical communication with the respective male grounding prong and male plug prongs and adapted to receive therein an electrical plug from an electrical apparatus which apparatus is to be protected from electrical surges from the electrical outlet plug;
• and
• (d) a varistor means comprising a metal oxide varistor of a flat circular material which changes to a dark color on activation which is in electrical communication to act as a surge protector for electrical signals from the electrical outlet plug, the varistor means positioned slightly below the face of the transparent plug body which face extends upwardly so that the varistor means is easily visible when the surge protector plug is inserted into the electrical outlet plug and adapted to be activated and change to a dark color on the occurrence of an electrical surge whereby the user by visually observing the varistor means can determine if an electrical surge has occurred and can replace the said activated surge protector.
