摘要： A non-removable handle tie is connected to a pair of push-push type circuit breakers arranged in back-to-back relationship. The handle tie includes a central finger engageable portion and oppositely extending offset sections entered into cavities of the circuit breakers through rear openings into the cavities. Both the stamped metal and molded plastic constructions for the handle tie are loosely connected to the circuit breaker handles to permit tilting of the handle tie when both handles are not in corresponding positions, yet this connection permits simultaneous manual operation of both circuit breakers. In the molded resilient construction of the handle tie the unit is formed so as to experience controlled bending when the handles are not in corresponding positions. However, when the handle tie is depressed for manual operation, the handle tie exhibits rigidity in transmitting operating forces.

摘要： A multipole heavy duty manually or remote control operated switch is constructed of individual pole units stacked side-byside. Each pole unit includes first and second molded insulating members joined side to side to form a housing having a chamber, and both stationay contacts and an arc chute are within said chamber. A so-called four-bar linkage connects the switch arms to a bail connected to a common operating mechanism. When the switch is open, the movable contact ends of the switch arms extend beyond the confines of the pole unit housings to provide a positive visual indication that the switch is open. Each switch arm is constructed of two abutting sheet metal members having oppositely extending formations providing contact areas and an area for making a mechanical connection to the operating bail.

摘要： A circuit breaker having a pair of spaced insulated stationary contacts engageable by a pair of movable contacts mounted to a conducting bridge on a movable contact arm is provided with common means defining main and auxiliary pivot axes for the contact arm. The main axis is transverse to the arm and provides a center about which the movable contacts pivot as they separate from the stationary contacts. The auxiliary axis is parallel to the longitudinal axis of the arm and provides a center for limited pivoting of the arm to obtain automatic seating of the movable contacts on the stationary contacts.
