Abstract
A non-contact auxiliary switch for a circuit breaker includes a target having first and second positions corresponding to open and closed positions of separable contacts. A non-contact sensor is responsive to the first and second positions of the target to generate first and second output signals. A movable slider member carries the target and is structured to slide within a holder inside the housing of the circuit breaker and to be coupled to and moved by an operating mechanism responsive to the open and closed positions of the separable contacts. This effects one of the first and second positions of the target when the separable contacts are closed and the other of the first and second positions of the target when the separable contacts are open.
