<p>The present invention provides a circuit breaker assembly having a base, cover, and switch handle adapted to withstand an external force applied to a lever of the switch handle. During normal operation the handle rotates on small-diameter pivots in elongated bearing slots. When the lever is inadvertently struck, such as when the circuit breaker is dropped on the lever, the pivots slide in the elongated bearing slots. The force is borne by large-diameter hubs which come into contact with mating bearing surfaces. Thus, the pivots are not shorn off during such incidents, which would damage the circuit breaker.</p> |
