<p>The locking cylinder is firmly mounted on the switch shaft, while the armature locking levers are pivotally mounted outside the shaft. The levers alternately engage two recesses in the locking cylinder, being moved by springs in one direction and in the other one by shifting sections of the key lower edge. Between the key lower edge and the movement transmission shanks of the levers (57, 60) is provided a transversely slidable and pivotable intermediate element (68) whose upper edge has a mirror counter shape of the irregular shape of the key edge.</p> |
