A crank arm of an auxiliary rotary switch in a circuit breaker changes electrical connections of contacts in the auxiliary rotary switch when the crank-arm is rotated about its axis. An auxiliary switch actuator decouples abrupt forces from being applied to the crank arm resulting from closing main contacts of the circuit breaker. In response to the main contacts starting to close, the crank arm is set into rotation by motion of a connection-state link that is coupled to the main contacts. The rotation of the crank arm continues up to a point at which the rotation is stopped, while the connection-state link continues its motion without being connected to the crank arm. In this manner, the connection-state link is decoupled from the crank arm, to relieve the crank arm from receiving the abrupt forces conducted by the connection-state link resulting from the main circuit breaker contacts closing.
