  • the coil is also fixed in the housing.
  • the construction of the bridge 40 has to be adapted to the design of the DC drive, for which an example in FIG. 15 is shown in an exploded view.
  • the coil 70 which is equipped with a winding, permanent magnet and a central rod armature, is formed in the coil holder with connections as a compact component, see FIG. 15.
  • the bridge for mounting the coil is 70 in the area of the lower cross member with a wider projection 401. The projections required for the attachment of the armature of the AC drive on the upper cross member of the bridge 40, see FIGS.
  • FIG. 8 A variant of the coil anchoring or the anchoring of the coil holder 72 of the coil 70 in the carrier module 30 is shown in part in FIG. Instead of the plug-in feet 724a, b, c of the coil according to FIG. 8 for AC drive, the feet of the coil holder 72 are hook-shaped curved inwards, see the hook-shaped feet 724e, 724d. These hook-shaped feet of the coil former 72 then reach through the recesses 309 of the base 340 of the base trough of the carrier module and snap behind projections 341, 342 in the bottom wall in the region of the openings or recesses 309, which are designed as latching cams.
  • the coil 70 inserted into the carrier module 30 together with the magnetic body 60 is then inserted into the lower housing part 10 during final assembly, as shown in FIG. 14a.
  • the final fixing and fixing of the coil 70 with respect to the carrier 30 then takes place when the hook-shaped feet 724e, 724d rest on corresponding projections 141, 140 formed on the bottom of the lower housing part 10 between the two housing parts, as described above, the coil 70 is then clamped and fixed in the housing.
  • the configuration of the coil holder in the carrier module and in the housing of the switching drive, shown in part in FIG. 12, has, for example, four hook-shaped feet on the underside of the coil body, which are each formed in pairs on opposite sides of the coil body. It is also possible to arrange two hook-shaped feet on one side and a hook-shaped foot centrally on the other side. Since the coil former is injection molded from a suitable thermoplastic, the hook-shaped feet are sufficiently resiliently flexible so that they can snap behind the projections 341, 342 when inserted into the carrier module.
