摘要： An auxiliary interlock switch for a DC contactor has a reciprocable one-piece insulating contact carrier and plural bridging contacts interchangeably mounted thereon in alternative positions to provide different desired arrangements of normally open and normally closed contact sets with the stationary contact posts. The contact carrier has a return spring compressed within a spring-receiving cavity and elongated abutment-receiving apertures registering with opposite ends of said cavity through which an abutment member, that is releasably assembled to the contact carrier, may interchangeably freely extend to permit relative movement therebetween and against which one end of the return spring reacts to resiliently bias the contact carrier against reciprocation in one direction. The bridging contacts may be easily removed in the field and reassembled in desired contact configuration and are of resilient metal with bifurcated ends having "chisel" surfaces which provide high unit area contact pressure and plural points of engagement with each stationary contact post to thereby increase electrical reliability.

摘要： A circuit maker and breaker has a removable arc chute for interrupting an arc formed between the movable and stationary contacts. A pivotally movable interlock device is mounted in a cavity in the insulating base of the circuit maker and breaker in the region where the contact-carrying armature is movable into engagement with a magnetic yoke to close the movable contact of the circuit maker and breaker into engagement with the stationary contact. The pivotally movable interlock device includes a plug-like member which is movable into the path of movement of the contact-carrying armature to prevent closure of the armature if the arc chute is not properly positioned on or is absent from the circuit maker and breaker. The interlock device is actuated by a lever which is engaged by a surface on the arc chute as the arc chute is slid into proper position on the circuit maker and breaker, to thereby move the interlock device out of plugging or blocking relation to the armature. In the absence of the arc chute, or in case of improper positioning of the arc chute, the interlock device will move about its pivotal axis to interpose the interlocking plug member into the path of closing movement of the contact-carrying armature to prevent closing of the armature and thus to prevent closing of the movable contact relative to the stationary contact. In one embodiment of the invention, when the arc chute is absent or improperly positioned the interlocking plug member moves due to the force of gravity into the path of closing movement of the contact-carrying armature; while in another embodiment of the invention when the arc chute is absent or improperly positioned the stored energy of a biasing spring moves the interlocking plug member into the path of closing movement of the contact-carrying armature. In the second embodiment, the force of the spring member may be, but is not necessarily, supplemented by the force of gravity in moving the plug member into the path of closing movement of the contact-carrying armature.
