Classification: CPC H  F | IPC H

Claim 0:
1. An electromagnetic actuator (10) comprising energizable stationary spool elements (1) having a stationary core area (2) assigned thereto, an anchor unit (3) which is moveable relative to the spool elements (1) and the core area (2) and has permanent magnet elements (4) and a pestle (5),
the anchor unit (3) being moveable along a longitudinal movement axis (L) into at least two actuating positions (A,B), and
the actuator (10) comprising retaining elements (7) which are spaced apart from the core area, are permanent-magnetically flux-conductive and are formed in such a manner-that, in a third actuating position (C) between the first and second actuating position (A,B) for interacting with the permanent magnet elements (4) of the anchor unit (3), the anchor unit (3) is retained in the third actuating position (C) between the first and second actuating position (A,B) and/or exerts a predefined force potential towards the actuating partner, and wherein the pestle (5) is disposed on one end of the anchor unit (3) and has a free end section (5a) for engaging in an actuating partner comprising a guide groove (11a, 11b) of a cam shaft (11).
