ABSTRACT:
An auxiliary switch operator for a circuit breaker operates auxiliary contacts between open and closed positions. The auxiliary switch operator includes a hub which is biased to follow a pole shaft of the circuit breaker and follow the pole shaft when it rotates in a first direction to close separable contacts of the circuit breaker. A first spring mechanism biases the hub to follow the pole shaft when the pole shaft rotates in the first direction. When the pole shaft rotates in the first direction, an arm of the hub engages a rotatable shaft to drive an operating lever and operate the auxiliary contacts to the closed position. When the pole shaft rotates in the second direction, another arm of the hub recharges the first spring mechanism. A second spring mechanism biases the rotatable shaft and the operating lever toward a position corresponding to the open position of the auxiliary contacts when the pole shaft rotates in the second direction.
