Claim Text:
1. An electromagnetic actuating apparatus comprising: a first armature arrangement which can be displaced in its axial direction between a rest position and an actuating position and is connected to a first actuating element, a first pole core which can be brought into a magnetic operative connection with the first armature arrangement, an axially oriented coil unit, which can be energized, for influencing a magnetic operative connection between the first pole core and the first armature arrangement, and a second armature arrangement which is connected to a second actuating element and can be displaced in its axial direction between a rest position and an actuating position, wherein a second pole core which can be brought into a magnetic operative connection with the second armature arrangement is provided, which second pole core is oriented axially with respect to the first pole core in order to influence its magnetic operative connection with the second armature arrangement by way of the coil unit, and a permanent magnet unit is provided, its magnet axis of which is oriented radially and is stationary in order to generate a magnetic operative connection both between the first pole core and the first armature arrangement and between the second pole core and the second armature arrangement, wherein a first spring element is provided which prestresses the first armature arrangement against the first pole core in the actuating direction, wherein a second spring element is provided which prestresses the second armature arrangement against the second pole core in the actuating direction.
