  • a shaft of the control pole 36 carrying the coil 35 lies in the plane of the holding pole 34. Only the upper part of the control pole 36 is bent, so that it mentioned the opposite of the holding poles 34 occupies a laterally offset position.

  • laterally offset arrangement of the control poles 36 eliminates the air gaps between the poles 34, 36 mentioned in connection with FIG. 4. Since the control poles 36 continue to overlap with the holding poles 34 in the region of the intermediate spaces 37, they can cross over to the poles 34 , 36 facing feet 30 of the selection Boards 16 bumpless and without falling into air gaps, over which the surfaces of the poles 34, 36 lie flush in one plane.
  • the arrangement of the magnetic pattern selection means 32, 33 is such that when, after a corresponding switching operation, electrical current flows through the coils 35, the polarity of the control pole 36 is opposite to the polarity of the adjacent holding pole sections and the effect of the holding poles 34 in Area of the control pole. In this case, the control foot 30 is no longer held by the holding poles 34 when the intermediate space 37 overflows, so that the selection board 16 can now be moved freely. As a result, the spring 22 can move the selection board 16 in FIG.
  • control poles 36 are bent and are thereby laterally offset from the holding poles 34.
  • the arrangement is reversed: there the holding poles 34 are in the region of the intermediate spaces 37 cranked, and the control poles 36 are thereby Free space created laterally offset to the sections of the holding poles 34 delimiting the interstices 37. Furthermore, the control poles 36 in turn overlap the end sections of the holding poles 34 which delimit the interstices 37.
  • the holding and control poles 34 and 36 may have a mask 38 (Fig. 2), e.g. made of plastic or other non-magnetic material, which surrounds the poles 34, 36 of the adjacent tracks at the top and - in particular the control poles 36 - keeps them at a predetermined, fixed distance.

  • FIG. 7 which corresponds to the embodiment according to FIG. 6 with respect to the straight design of the control poles 36, these control poles 36 lie on the inner sides of the tracks formed by the holding poles 34 or between these tracks.
  • the shafts of the control poles 36 are not cranked, but are formed in a straight line in the same way as in the embodiments according to FIGS. 6 and 7.
  • FIGS. 10 and 11 show an embodiment of the control pole 36, in which this pole has two shanks 41, 42 which are designed as parallel legs and each carry a coil 35.
  • the magnetic force of the control pole 36 can be increased accordingly by using two coils.
  • FIG. 11, which is a plan view in the direction of arrow B in FIG. 10, shows how the control pole 36 provided with two coils 35 is arranged in the space between cranked end sections of holding poles 34. It is furthermore possible to arrange a control pole 36 provided with two coils 35 according to FIG. 10, similar to that in FIGS. 6 and 7, to the side of non-cranked holding poles 34.
