Abstract
A locking device includes a housing, a plunger slidably supported in the housing for displacement in a first direction between two end positions and an electromagnet disposed in the housing and having a solenoid and an armature displaceable in a second direction by the force of a magnetic field generated upon energization of the solenoid and a coupling arrangement for operatively connecting the armature with the plunger for affecting the position of the plunger dependent upon the position of the armature. The coupling arrangement comprises a switch-over device which has two stable end positions and which is force-transmittingly connected to the plunger.
