Abstract: A circuit breaker with an electrical insulator slide interposable between two generally convex contacts thereof and a rocker button rotatably trap mounted on a protrusion extending from the inside wall of the case which interacts wtih pivot points at one end of the slide to translate the rocking motion of the button into a linear motion displacement of the slide. The slide includes generally parallel elongate spaced apart standoff protrusions adapted to maintain the operating electrical contact surface of the movable contact withdrawn from contact with the slide when in the tripped position and during a resetting of the circuit breaker. The slide also includes a contoured portion adapted to generally mate with curved portions of but be visually distinguishable from the rocker button to present a readily discernable indication that the circuit breaker is in the tripped condition.

Abstract: A bimetallic circuit breaker with an electrical insulating slide interposed between the contacts thereof in the contacts open position in which the terminals, the bimetallic element, the insulator slide, the button (connected to the slide) and the spring biasing the button and the slide to the contacts open position of the circuit breaker are all carried by an insulator frame so that they may all be preassembled together and inserted into the housing for the circuit as one sub-assembly.
