Abstract
An electromagnetic drive is described that exhibits two electromagnets (2, 3) situated opposite one another and an armature (10) between them that can be moved back and forth. The armature (10) is held in an intermediate position by elastic forces and brought into a terminal position by the power of the electromagnets (2, 3). The armature (10) is mounted using a torsion spring (6) and at least one drive together with its bearings forms a single structural unit.
