  • Non-contact auxiliary switch and electric power apparatus incorporating same
    Patent number: 7034644
    Abstract: 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.
