Abstract

PURPOSE:To enable sure return of a shield plate by furnishing a resetting means for forced return of the shield plate interlocked with off-action of a handle. CONSTITUTION:Resetting after repair of shortcircuiting is made by felling a neutrally positioned handle 6 from the condition shown by assumed line to the off condition on the righthand. Turning of this handle 6 restitutes a tripping means 24 by a return spring 28 to put a latch 23 in latched state. Thereby off state is obtained. A resetting boss 68 of the handle 6 pushes the follower part 73 of a resetting means 71 so as to turn it counterclockwise. When the tripping means 24 is not restituted due to increase of the wear resistance caused by dirt or contact abrasion powder, which has intruded into the gap between a shield plate 9 and a guide 46, an actuating part 74 pushes the tripping means 24 to enable sure restitution.
