Die Erfindung betrifft Unterbrecherkontakte fur elektrische Stromkreise.The invention relates to break contacts for electrical circuits.

Zweck ist die Unterbrechung des Stroaflusses in elektrischen Stromkreisen.The purpose is to interrupt the flow of electric stroa Circuits.

Ee ist bekannt, daß Unterbrecherkontakte in elektrischen Strom« kreisen zur Unterbrechung des Stromflueses verwendet werden. So zum Beispiel in Sehaltern, Klingeln„ Summern, Zerhaekern; in Priaärstromkreisen von Zündsystemen für Verbrennungsmotoren usw.It is known that breaker contacts in electrical current « circuits can be used to interrupt the current flow. For example in Sehaltern, Bell "Buzz, Zerhaekern; in Primary circuits of ignition systems for internal combustion engines, etc.

Bei schnellem Wechsel von öffnen und Schließen der Unterbrecher« kontakte tritt durch Stromfluß und Lichtbogen eine Erwärmung derselben ein«. Heist steigert sich diese Erwärmung bis sum Schmelzpunkt, sodaß Material von der einen Kontaktflache auf die andere wandert. Das Ergebnis ist dann, daß ein Kontakt eine Vertiefung aufweist und der Gegenkontakt einen Höcker. Damit ist keine einwandfreie Unterbrechung mehr gewährleistet; der Zeitpunkt der Unterbrechung wird während des Abhebens verschoben und führt bei elektromagnetisch bewirkter Abhebung der Unterbrecherkontakte voneinander - in Zerhaekern, Sommern, Klingeln uew· - zu Frequenz= Veränderungen. Bei mechanisch zwangsläufig erfolgender Öffnung 4er Unterbrecherkontakte, zum Beispiel in Zündsysteraen von Verbrennungsmotoren tritt eine Veränderung des Zünd. Zeitpunktes ein« Dies hat eine Laufuoruhe des Motors und somit einen Leistungen Abfall zur Folge.With a quick change from opening and closing the breaker « contacts heat up through the flow of current and arcing «. Heist increases this warming to sum Melting point, so that material migrates from one contact surface to the other. The result is that a contact is a Has recess and the mating contact has a hump. This means that a faultless interruption is no longer guaranteed; point of time the interruption is postponed and leads during the take-off in the case of electromagnetically caused separation of the breaker contacts from one another - in Zerhaekern, summers, ringing etc. - to frequency = Changes. In the case of mechanically inevitable opening 4 break contacts, for example in ignition systems from Internal combustion engines experience a change in ignition. Point in time a «This has a quiet running of the engine and thus a performance Waste.

Der Erfindung liegt die Ausgabe zugrunde, die Anfälligkeit von Vaterbrecherkontakten in Bereich des Verschleißes und der frühen Beschädigung au unterbinden, die Betriebssicherheit der Systeme in tenen Unterbrecherkontakte verwendet werden zu erhöhen, und die Seitepanne von einer Wartung bis zur nächsten zu verlangern.The invention is based on the issue, the susceptibility of Prevent father breaker contacts in the area of wear and tear and early damage, the operational safety of the systems in tens breaker contacts are used to increase, and the Extending the page breakdown from one maintenance to the next.

Diese Aufgabe wird Erfindungsgemäß d&äurch gelöst, daß die Unterbrecherkontakte mit Rillen versehen werden, die bein Offnen undAccording to the invention, this object is achieved in that the Breaker contacts are provided with grooves that open and
