ABSTRACT:
An electrical switch includes a rocker-type actuator adapted to be pivoted between first and second positions within a housing in order to close and open switch contacts. The actuator carries a latch which normally engages the housing to prevent the actuator from being pivoted to its switch-closed position. By pulling on the latch and then lifting on the actuator, the actuator may be pivoted to its switch-closed position; the two-step operation protecting against accidental actuation of the switch. The actuator may be returned to its switch-open position by a simple single motion thereby enabling rapid opening of the switch under emergency conditions. In one embodiment, the latch cannot be moved to an unlatched position and the switch cannot be actuated unless an authorized person with a key connects the key detachably to the latch.
