Electric switch with arc chute, radially converging arc splitter plates, and movable and stationary arc runners

摘要

A contactor for switching electric current has a stationary contact and a movable contact which when driven by a solenoid moves into and away from abutment with the stationary contact. An arc chute includes a plurality of splitter plates which extend radially from a center point in a geometric arc around the stationary contact on a side that is opposite to the movable contact. A curved arc runner is connected to the stationary contact to guide an electrical arc travelling between the stationary contact and each of the splitter plates. An elongated arc runner is connected to the movable contact to guide the electrical arc between the movable contact and splitter plates at the ends of the geometric arc.
