    Abstract: A high voltage disconnect switch in which the hinged member pivotally supporting the switch blade is composed of aluminum alloy, the sleeve for rotating the blade is composed of copper alloy with copper alloy conductors on opposite sides of the contact surface of the sleeve, and the circuit through the switch passing through the sleeve and conductors rather than through the hinged member.

    Abstract: 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.
