The rocker cam spring is housed in a spring chamber longer than itself, allowing the rocker cam spring to float.

Abstract: 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. Under abnormal conditions that occur when the lever of the switch handle is inadvertently struck, such as when the circuit breaker is dropped on the lever of the switch handle, the pivots slide in the elongated bearing slots. The force is borne by large-diameter hubs which come in contact with mating bearing surfaces. Thus, the pivots are not shorn off during such incidents, which would damage the circuit breaker.

Abstract: A lever type switching assembly having a pair of generally U-shaped spring blade contact members disposed in oppositely spaced-parallel arrangement for alternate actuation by a common paddle lever frictionally contacting the contact members for effecting switching upon user movement of the lever in a clockwise direction. Each contact blade member has one end pivoted on a center contact for rocking motion to cause the U-shaped region and the opposite end of the blade member to make and break contact with side-contacts on opposite sides of the center contact. Overtravel of the paddle in one direction after actuation causes the contact blade member to break from the side contact and make contact with an auxiliary contact. A spring biased plunger on the paddle lever engages a detent surface on the base to give a tactiley discernible indication.

Abstract: A rocker type switch actuator for sequentially actuating plural switches upon rotation in either of opposite directions from a neutral position. The actuator has a springloaded plunger which engages a recess in the housing. The recess has a central depression for neutral position detention and steep ramps disposed spaced on either side of the neutral recess. The steep ramps provide first actuation position detent action against the plunger upon user movement of the rocker from the neutral position. The steep ramp requires a substantially/increased user applied actuation force to move the plunger beyond the initial actuation position; and, upon the plunger cresting the top of the steep ramp a sudden decrease in user applied force is tactilely discernible to provide an indication that the second switching position has been reached.
