PCT No. PCT/DE96/02316 Sec. 371 Date Jun. 11, 1998 Sec. 102(e) Date Jun. 11, 1998 PCT Filed Dec. 2, 1996 PCT Pub. No. WO97/22985 PCT Pub. Date Jun. 26, 1997A device in which a triggered switching device (1), for example a contactor, may be maintained in its ON position even if the power supply is interrupted. The invention includes a mechanical locking system having a pawl (11), which is held in a bearing (12). When the switching device (1) is triggered, the pawl (11) engages under the loading of spring force in a recess (5) in a contact carrier (4). It is possible via an unlocking device (7) to actuate an angle lever (16) which pivots the pawl (11) and releases the contact carrier (4). Unlocking can also be performed by hand via an ON-OFF indicator (23) of a second contact carrier (8). The bearing (12) may be shape-coded to ensure that it is installed properly oriented in the openings (13, 14) of the side walls (3, 6) of the switching device (1) and the locking device (7).
