Abstract:
An actuation mechanism comprising: an electromagnetic drive (2, 3, 10) having two electromagnets (2, 3), whose pole surfaces are at least in part facing towards each other, and with an armature (10) that is movable back and forth between these pole surfaces, the armature (10) with deactivated magnets (2, 3) is brought by elastic force (6, 7) into an intermediate position and held there and on activation of one of the electromagnets (2, 3) is brought into a terminal position in the proximity of the pole surfaces of the respective electromagnet (2, 3), whereby the armature (10) is mounted using torsion springs (6, 7) which produce the elastic force at least in part, and acts upon a part (18) to be driven and incorporates at least one drive (2, 3, 10) together with a bearing into a structural unit, and said structural unit is fastened onto a component (20), which contains the part (18) to be driven, and a mounting or carrier element (1a), in particular a substantially closed case for accommodating several structural units, said mounting or carrier element (1a) is fastened onto the component (20).
