ABSTRACT:
An improved circuit-breaker position-indicator is provided for a gas-type circuit-interrupter in which the circuit-breaker structure is enclosed within an outer pressurized casing at a different pressure than the gas pressure interiorly of the circuit-breaker itself. Improved means are provided for effecting manual movement of the circuit-breaker contacts by a hand-jack assembly, when desired. Visible safe indication of the correct circuit-breaker open and closed-circuit positions is obtained at all times for safe and dependable operation of the circuit-breaker.
