    摘要: The auxiliary switch includes a non-contact sensor, such as a Hall effect device, that is switched by the condition of a magnetic field. The magnetic field condition is effected by a movable contact indicator that moves between open and closed positions with the separable contacts of the electric power apparatus. A magnet may be attached to the movable contact indicator, or the movable contact indicator can be magnetized to form the magnet. Alternatively, the moving contact indicator can intercept or not intercept a magnetic field produced by a fixed magnet spaced from the sensor. The Hall effect device may be mounted on the outside of the nonmagnetically permeable housing of the electric power apparatus, or inside if there is sufficient room. In either case, no mechanical coupling is required for the sensor.

    摘要: A circuit breaker includes a housing having an opening, separable contacts within the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a generally transparent operating handle having a portion protruding through the opening of the housing. An auxiliary switch associated with the operating mechanism provides a first normally closed output when the separable contacts are open and a second normally open output when the separable contacts are closed. A first LED indicator cooperates with the first output, is proximate the operating handle and is illuminated when the separable contacts are open. A second LED indicator cooperates with the second output, is proximate the operating handle and is illuminated when the separable contacts are closed. One of the first and second LED indicators illuminates the operating handle.

    摘要: A circuit breaker includes a case, separable contacts having a fixed contact and a movable contact, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a closed position, an open position, an operating handle for moving the operating mechanism between the open and closed positions, a movable contact arm carrying the movable contact, a linkage having a first end and a second end, and a snap lever. The second end of the linkage is pivotally mounted to the movable contact arm. The snap lever holds the linkage in the open position of the operating mechanism and releases the linkage as the operating handle moves from the open position toward the closed position of the operating mechanism, in order to snap close the separable contacts.
