In addition, the correct armature stroke ensures that the hi tsanke7 now strikes a friction-free passage of the auxiliary armature for one and the magnetic core 1, so that the armature / disturbed evasion possibility of the same is kept at the rest, while the main armature 4 still allows a slight passage of the actual armature . 50 carries out the rest of the movement until it also hits the. on impact and stopped by this is pivotable transversely to the longitudinal axis of the magnet core, the leaf spring 8 being formed by a lever mounted to a certain extent, so a position is deflected. In the de-excitation of the magnet formation of the invention before that the auxiliary armature in core 1 is released in the reverse order to the operation described above with respect to the central axis of the magnetic core 55 first the main asymmetrical arrangement that it is arranged with that of the armature 4 of the magnetic core 1, what is supported by the previously off-bearing point of the armature opposite half-steered leaf spring 4, and only then does the magnetic core work together. In this way, the auxiliary armature 7 is lifted from the magnetic core 1 in an extremely simple manner and only by using the known lever laws and together with the main armature 4, the effect can be increased not insignificantly after falling below a certain amount of the auxiliary armature, so sen armature stroke on the opening 9 on both sides over that the projecting leaf spring 8 which is basically aimed at by the invention strikes. Then return to the goal of increasing the tightening force in advantageous main anchor 4 and the auxiliary anchor 7 is supported together in ter way. their drawn rest position back.
