    摘要： An electrical switch having fixed contacts with which a movable contact is adapted to selectively engage as the switch is actuated. The movable contact is so constructed and so mounted in a recess in a carrier therefor that misalignment or tilting of the carrier will not significantly affect engagement between the contacts.

    摘要： In relays using conductive resilient contact pads formed of fine wire to decrease contact bounce and provide contact surface wiping, damage to the fine wires by contact arcing is obviated by provision of rigid auxiliary contact surfaces which open after the fine wire surfaces open in order to diver any arcing to the rigid auxiliary contact surfaces. Several spring-operated and several magnetically operated auxiliary contact arrangements are shown.

    摘要： A circuit breaker for metalclad switchgear use is provided using vacuum-interrupter elements in substitution of the usually provided magnetic and insulating plate structures, customarily employed. A resilient mounting for the interrupter elements is provided, together with massive end contact blocks for heat dissipation generated within the vacuum-interrupter elements. A pivoted operating lever, connected to the massive contact block secured to the moving contact of the vacuum-interrupter, is operated by a resilient connection to the insulating operating rod of the circuit breaker. Because of the reduced dimensions, the cubicle dimensions may be drastically reduced, if desired.
