Abstract
An electromagnetic actuating apparatus having an electromagnetic actuating unit which can be operated in order to exert an actuating force for an elongated plunger unit, wherein the actuating unit is provided in a housing along its actuating direction. The actuator unit forms an engagement surface which is planar in places and can be moved axially in the actuating direction, at an engagement end facing the plunger unit, an end surface of the plunger unit on the engagement side interacts detachably with the engagement surface, and the plunger unit is seated by magnetic attraction with its end surface on the engagement side on the engagement surface of the actuator unit, wherein the plunger unit is preferably designed to be soft-magnetic and furthermore preferably composed of soft iron, in the area of the end surface.
