kopfes 1 des Klebstiftes oder nur unter ihrem Teil ausgebildet werden.
Die Beeinflussung des magnetischen Flusses durch die erfindungsgemässe Ausführung der elektromagnetsehen Schalteinrichtung mit Klebstift ist für die Praxis vernachlässigbar. Ein bedeutender Vorteil dieser
Ausführungbestehtdarin, dass der Klebstift mittels Spritzgussverfahren aus Plastikmaterial hergestellt werden kann, was sonst aus presstechnischen Gründen in den Stärken von 0, 1 mm und weniger überhaupt nicht durchführbar ist. Die Erfindung ermöglicht somit eine einfache und verlässliche Möglichkeit der Erzeugung, die im Falle des Spritzgussverfahrens halbautomatisch oder auch vollautomatisch vor sich gehen kann.
PATENTANSPRÜCHE :
1. Elektromagnetische Schalteinrichtung, insbesondere Relais, Wähler od. dgl., mit zwei durch einen Luftspalt getrennten, gegenseitig beweglichen Organen, z. B. Relaisanker und Magnetkern bzw. Polschuh, in deren Arbeitsstellung der Restluftspalt durch den verbreiterten Wirkkopf eines aus unmagnetischem, vorzugsweise Kunststoff-Material gefertigtem in einem der Organe befestigtem Klebstiftes definiert ist, dadurch gekennzeichnet, dass wenigstens in einem der Organe (2,3, 4) eine Ausnehmung zur Aufnahme des Wirkkopfes (1) des Klebstiftes in einer solchen Tiefe (II in Fig. 1, IV in Fig. 2) ausgearbeitet ist, dass der Wirkkopf (1) aus dieser Ausnehmung in der für die Bemessung des Restluftspaltes erforderlichen Höhe (I) herausragt.

head 1 of the glue stick or only under its part.
The influencing of the magnetic flux by the embodiment according to the invention of the electromagnetic switching device with glue stick is negligible in practice. A major benefit of this
The design consists in the fact that the glue stick can be manufactured from plastic material by means of an injection molding process, which otherwise cannot be carried out at all in thicknesses of 0.1 mm and less for press-related reasons. The invention thus enables a simple and reliable possibility of production which, in the case of the injection molding process, can take place semi-automatically or also fully automatically.
PATENT CLAIMS:
1. Electromagnetic switching device, in particular relays, selectors or the like. With two mutually movable organs separated by an air gap, eg. B. relay armature and magnetic core or pole piece, in the working position of which the remaining air gap is defined by the widened active head of a glue stick made of non-magnetic, preferably plastic material, fixed in one of the organs, characterized in that at least one of the organs (2,3, 4) a recess for receiving the knitting head (1) of the glue stick at such a depth (II in Fig. 1, IV in Fig. 2) is worked out that the knitting head (1) from this recess in the required for dimensioning the remaining air gap Height (I) protrudes.
