Abstract

A shorting switch (2) includes a vacuum switch (4) having fixed and movable contact assemblies (8, 10) and a driven member (26). A spring cover tube (38) and bushing (36) mount the driven member (26) for linear movement along a path substantially parallel to a longitudinal axis of the movable contact assembly (10). The driven member (26) moves the movable contact assembly (10) between open and closed circuit positions. A compression spring (40) has a compressed state and a released state, which moves the driven member (26) and movable contact assembly (10) to the closed circuit position. A release bolt (32) has an opening (68) therein and is coupled to the driven member (26) to normally maintain the compression spring (40) in the compressed state. A charge (60) is disposed in the opening of the release bolt (32) and is actuated to fracture the release bolt and release the compression spring (40) to the released state. First and second terminals (16, 22) are respectively electrically interconnected with the fixed and movable contact assemblies (8, 10).
