Abstract
A device for manually turning-on at least one circuit-breaker from the front panel of a cabinet includes at least one sleeve having a front end and a rear end. The sleeve extends through an aperture in the front panel and is movable between a backward position, in which the front end of the sleeve projects slightly from the front panel, and a forward position, in which the front end of the sleeve projects away from the front panel. A spring is compressed to push the sleeve from the forward position to the backward position. A rod is operably connected to the sleeve so as to be displaced following the forward movement of the sleeve and to remain in its position uneffected by the backward movement of the sleeve. A linking bar is provided to interconnect the rod and a switch member of the circuit-breaker, and the linking bar is adjustably connected to the rod so that the backward position of the sleeve correlates with the turned-off position of the circuit-breaker and the forward position of the sleeve correlates with the turned-on position of the circuit-breaker.
