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spaced apart standoff protrusions adapted to maintain the operating electrical contact surface of the movable contact withdrawn from contact with the slide when in the tripped position and during a resetting of the circuit breaker.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.
