Description

tier Teil des IsolierstolTkörpers 6, der das Schallglicd 8 und die Kegelfeder 9 trägt, mit einer gewindeartigen Kurvenbahn in Form einer nockenartigen Crliöhung da versehen, auf der da» Schaltglied gleiten kann.part of the animal IsolierstolTkörpers 6, which carries the Schallglicd 8 and the conical spring 9, provided with a thread-like cam track in the form of a cam-like Crliöhung there can slide on the as "switching element.

Fig. 3 zeigt das Schaltglied 8, das an seinem inneren Rand mit einer Ausnehmung 8 α versehen ist, die der Erhöhung 6 α des Teiles 6 entspricht. Wird also beim Einschalten nach dem Aufsetzen des Schaltgliedes 8 auf die Kontakte 2 und 3 der Schaltstößel 6, 7 in Richtung des Pfeiles weiterbewegt, so wandert das Schaltglied 8 auf dem schaftartigen Teil des Isolierstoffkörpers 6 entgegen der Wirkung der Feder 9 und wird dabei entsprechend der Kurvenbahn 6 α gedreht. Hierdurch wird eine zusätzliche Schabewirkung an den Kontaktstelle;» bewirkt, die ζ Beseitigung von störenden Ablagerungen d.enen kann Dies kann im Zusammenwirken mit der Aub dung der Oberflächen der Kontakte 2 und 3 als gtahn« Oberflächen geschehen oder aber auch unabhängig davon als alleinige Maßnahme.3 shows the switching element 8, which is provided with a recess 8 α on its inner edge, which corresponds to the elevation 6 α of the part 6. If so when switching on after placing the switching element 8 on the contacts 2 and 3 of the switching plunger 6, 7 is moved in the direction of the arrow, the switching element 8 migrates on the shaft-like part of the insulating body 6 against the action of the spring 9 and is in accordance with the Curved track 6 α rotated. This creates an additional scraping effect on the contact point; causes disruptive deposits to be removed. This can be done in conjunction with the formation of the surfaces of contacts 2 and 3 as smooth surfaces or, independently of this, as the sole measure.

Die gewindeartige Kurvenbahn kann auch einen anderen Aufbau zeigen, indem z. B. eine Vertiefung auf dem Isolierstoffkörper 6 und ein zapfenartigerThe thread-like curved path can also show a different structure by, for. B. a recess on the insulating body 6 and a pin-like
