- the yoke 20 is shaped to form a space parallel to the longitudinal extension of the coil 17.18 runs.
- the yoke 20 is designed as a bent sheet metal, that on the facing away from the connection to the core 1 End has an end face 25 which with the flange 24 of the Coil body 17 is approximately aligned.
- the gap is the disc-shaped permanent magnet 21 with a first 27 and a second pole face 28 and the flux plate 22 housed, the yoke on the first pole face 27 20 with its surface facing the coil 17, 18 and on the the second pole face 28 the flux plate 22 abuts.
- the permanent magnet 21 forms with the yoke 20 and the flux plate 22 as Pole shoes a horseshoe-shaped magnet system, which by the Flußblech 22 formed leg at its end an edge surface 29 has.
- the holder of the yoke 20, the permanent magnet 21 and the flow plate 22 takes place in a plastic carrier 39.
- the end of the protruding from the flange 24 of the bobbin 17 Kerns 19 is widened in a cone shape, thereby increasing the size Contact surface 30 for creating a hinged anchor 31 (FIG 4) created is.
- can also be used as core 19 Use a rivet at one end of enlarged contact surface 30.
- the hinged anchor 31 has a plate-shaped area 32 a contact surface 33 on which one with the contact slide 14 engaging web 34 connects (see FIG 4).
- the hinged anchor 31 has a first stamp 35 (see FIG. 5) for contact with the edge surface 29 of the flow plate 22 and with a second embossing 36 for abutment on the end face 25 of the yoke 20 provided with the currentless coil 18, i.e.
- the hinged anchor 31 is on the narrow sides in the area the first embossing 35 with recesses 37 (see FIG 4).
- the contact surface 30 on the core 19 and the edge surface 29 on the flow plate 22 are preferably aligned with one another (see FIG. 1).
- the End face 25 on the yoke 20 for the installation of the hinged anchor 31 coil 18 through which no current flows is opposite the imaginary one Connection line between the contact surface 30 and the Edge surface 29 of the flux plate 22 is set back in the direction of the coil 18.
- the hinged armature 31 With coil 18 carrying current, i.e. in the ON position of the Switching device according to FIG 1, the hinged armature 31 is in a row the magnetic force of the coil 18 with its contact surface 33 the contact surface 30 of the core 19 and is still above its embossing 35 through the edge surface 29 of the flow plate 22 held. In this position there is between the others Embossing 36 of the hinged anchor 31 and the end face 25 of the Yokes 20 a space.
- the hinged anchor 31 In the OFF position of the switching device 2, in which the hinged anchor 31 exclusively held by the magnetic force of the permanent magnet 20,21,22 is, the hinged anchor 31 tilts through the embossing 35 formed edge, the contact surfaces 30,33 from each other be separated and the hinged anchor 31 with its through the further embossing 36 formed oblique surface to the End face 25 of the yoke 20 creates.
- the hinged anchor 31 works here as a lever that moves the contact slide 14.
- the electromagnetic switching device described is a for the PCB mounting suitable mini contactor, its drive is supported by a permanent magnet.
- a permanent magnet In addition to the in 1,2 shown monostable version is also a bistable Execution possible in which the two stable Switch positions can be achieved by reversing the coil current are.
- the structure is particularly cheap Position of the permanent magnet marked in the iron circle, which at the same time also allows a compact design.
- the difference to other known magnet systems can in the present Bracket of the hinged anchor dispensed with an anchor pressure spring will.
