of the iron core illustrated in fig1 and 2 the first iron core 21 has an associated first coil 23 the second iron core 22 has an associated second coil 24 the first coil 23 and the second coil 24 are arranged on free limbs of the iron cores the double linear magnetic drive 20 has an armature 25 to which a yoke 26 is attached centrally the armature 25 is in a linear extended form and at its ends has a first permanent magnet 27 and a second permanent magnet 28 the first iron core 21 the first coil 23 and the first permanent magnet 27 interact in the same way as the second iron core 22 the second coil 24 and the second permanent magnet 28 as described above with reference to fig1 and 2 the mirror image configuration with respect to its axis of symmetry 29 as well as the shape of the armature 25 mean that both the first coil 23 and the second coil 24 can be used for movement of the armature 25 from a first limit position to a second limit position and vice versa in the same way as described with reference to fig1 and fig2 the yoke 26 in each case acts as a bridge for a gap in the first.
