Abstract: A combination disconnect/reversing switch for use in explosive environments for isolating an electrical power source from a three-phase motor or for reversing the operation of a motor. The disconnect/reversing switch comprises a handle, mounting plate, front insulator plate, mounting flange, front contact holder, moveable contact holder, rear contact holder, and rear contact retainer. The handle actuates the moveable contact holder between open circuit, or load-grounded, (or reverse in the case of a reversing switch) and closed (or forward) positions. The moveable contact holder contains three electrically conductive pin members which engage corresponding electrical contacts on either the front contact holder, corresponding to the open (or reverse in the case of a reversing switch) position, or rear contact holder, corresponding to the closed (or forward) position.

Abstract: A multi-position contact for use in high voltage switchgear utilizes a multi-laminar electrical contact and a movable contact blade to maintain continuous electrical contact with a first circuit component and a switch blade assembly movable concomitantly with said movable contact blade for selective connection to second or third circuit components.

Abstract: A switch operating mechanism for a multi-position switch utilizes a stored energy member to store input energy applied to the mechanism and then release the stored energy to move an associated switch responsive to a predetermined input to the mechanism. A gradual application of force results in a rapid discharge of energy to move the switch.
