ABSTRACT:
Upper and lower flexible blades carry normally closed contacts that are opened by upward movement of the upper blade responsive to snapping of a bimetal disc. The disc is reset by a pushbutton movable from a rest position to a depressed reset position. In its reset position, part of the reset button extends past the upper blade into engagement with the lower blade for moving and holding the lower contact away from the upper contact to prevent reclosing of the contacts until the pushbutton is moved back toward its rest position.
