description | An electric arc extinguishing mechanism (34) is provided for an electric current switching apparatus of the type having a pair of contacts which selectively engage to complete an electric circuit. The mechanism includes a plurality of splitter plates (40) located adjacent to the contacts and formed of electrically conductive material. Each splitter plate has a body of electrically conductive material, and a casing (44) with a pair of planar portions on opposite sides of the body and connected by the curved edge portion (50). The edge portion (50) is adjacent the contacts with the planar portions extending from the edge portion (50) in an open loop having a gap (56). Any arc introduced between adjacent splitter plates (40) moves around the open loop before being extinguished thereby not residing in one spot long enough to cause gross melting and associated erosion of the splitter plate. |
