ABSTRACT:
A device for sensing the position of a contact carrier of a contact includes a housing, a sensor supported by the housing and a latch that is movable by the contact carrier. The latch has a latch member located in proximity to the sensor and that is generally non-reflective. The sensor is configured to sense a presence or an absence of the latch member at one particular location depending upon the position of the contact carrier. A method of sensing position of a contact carrier of a contact module is also presented.
