Claims
- 1. A switching device comprising a housing defining therein a chamber, stationary contact means mounted in the chamber, movable contact means disposed in the chamber adapted to move into and out of engagement with the stationary contact means, actuation means extending from outside the housing into the chamber coupled to the movable contact means adapted to move the movable contact means, latching means disposed in the chamber adapted to maintain the stationary and movable contact means in engagement during preselected conditions, a cantilevered bimetallic current carrying assembly having one end fixedly supported in the housing and having a second distal end portion adapted to deflect upon being subjected to selected current conditions, the distal end portion of the bimetallic assembly operatively connected to a reaction surface of the latching means, the latching means including a latch surface operatively connected to the actuating means adapted to engage the reaction surface when the bimetallic assembly is at normal operating temperature upon actuation of the actuator means, a support member rockably mounted in the housing and mounting the reaction surface, a bracket being attached to the support member, the bracket having a portion spaced from the support member culminating in a free end, an ambient compensating strip of bimetallic material being cantilever mounted to the free end, the strip having a distal free end, a motion transfer member extending between the second distal end portion of the bimetallic current carrying assembly and the distal free end of the ambient compensating strip and being adapted to transfer motion therebetween, the bimetallic current carrying assembly being formed into a plurality of loops extending between the one end and the distal end portion and the distal end portion being disposed without additional fastening means in a block of electrically insulative high temperature resinous material to maintain the distal end portion of the loops aligned with one another so that upon being subjected to selected current conditions deflection of the distal end of the bimetallic assembly will cause the movable contact means to become unlatched.
- 2. A switching device according to claim 1 in which the said one end of the bimetallic current carrying assembly is disposed without additional fastening means in a block of electrically insulative high temperature resinous material.
