<p>A swivelling lever control that can be locked after being swiveled inwards and for closing switchboard cabinet doors has a trough set on the outer surface of a door, in which the driving device for the closure, such as gear drive, lever drive or locking shaft, is arranged. An actuating lever is articulated to the driving device so as to swivel out of the trough about an axis parallel to the supporting surface of the trough. A hook device on the actuating lever engages a back engagement surface of the trough when the actuating lever is swiveled in, thus retaining the actuating lever after it has been swiveled into the trough. The actuating lever projects at its free end beyond the trough and bears an unlocking device with an actuating surface for the hook device that can be actuated by a pressure acting away from the outer surface of the door.</p> |
