<p>This control comprises a pivotable actuating lever 6 whose ends forms a lug 20 for actuating the electric circuit of the latch and a heel 18 cooperative with a linkage for mechanically controlling the latch. A barrel 14 actuated by a key carries a locking cam 32 which, on one hand, actuates a bistable relay of the general electric supply circuit, and, on the other hand, forms an abutment 34 for stopping the pivoting of the lever 6. This cam may be shifted by means of the key so as to retract the abutment 34 and enable the lever to pivot until the linkage is brought into action for mechanically opening the latch.</p> |
