Abstract
A current limiting power switch has a monolithic stationary conductor with a conductor section that mounts fixed contacts that engage moving contacts on moving contact fingers to form a reverse current loop with the contacts closed. A terminal section projects transversely from one end of the conductor section and an arc runner section extends from the other end. The tapered arc runner has a generally laterally centered tapered area that gathers the arcs and urges them along a raised rib on the arc runner to an arc chute. A reinforcing rib running from the back of the conductor and arc runner sections to the terminal section resists distortion of the monolithic stationary conductor by the high temperatures and closing and electromagnetic forces during interruption.
