Abstract
An actuator means for an electrical switch concealed in a housing and operated by a handle externally mounted to the cover thereof, whereby, upon closing the cover, the actuator automatically moves in a rectilinear direction to locate the toggle operating lever of the switch and rotatably moves the externally viewed handle to preposition it to indicate the energization state of the switch. Alternatively, the actuator permits operation of the switch by rotating the externally accessible handle. This invention is especially suited to circuit breaker switches contained in explosion-proof or hazardous location-rated enclosures.
