Patent attributes
A locking device for an electric switch is disclosed which is movably guided in a withdrawable rack via an actuating shaft wherein the electric switch is placed in a preferred position, in particular in a disconnected position. In at least one embodiment, the locking device is movable from a release position in which the switch is displaceable in the withdrawable rack to a locking position in which the locking device blocks the switch displacement in a predetermined direction and the actuating shaft is actuated via an actuating crank. In order to safe the switch locking in the preferred position thereof, the locking device is movable to the locking position when the actuating crank actuation is blocked, only. The withdrawable rack, provided with the inventive locking device for the electric switch displaceable in the withdrawable rack via the actuating shaft, is also disclosed.
