Description
Die Erfindung bezieht sich auf elektrische Schalter mit zwei in Reihe liegenden Unterbrechungsstellen, von denen die eine früher als die andere öffnet.The invention relates to electrical switches with two interruption points in series, one of which opens earlier than the other.
Unterbrechungsstellen besitzen im allgemeinen aus hochwertigem Material bestehende Kontakte, um dadurch sehr hohe Schaltleistungen zu erzielen. Bei Schaltern mit zwei in Reihe liegenden und gleichzeitig öffnenden Unterbrechungsstellen sind alle Kontakte aus demselben wertvollen Material herzustellen, da an beiden Unterbrechungsstellen Lichtbogen auftreten und somit ein gleichmäßiger Kontaktabbrand gewährleistet ist.Break points generally have contacts made of high quality material in order to thereby to achieve very high switching capacities. For switches with two in series and at the same time opening interruption points, all contacts are to be made from the same valuable material, because arcs occur at both interruption points and thus an even contact erosion is guaranteed.
Bei dem obenerwähnten elektrischen Schalter mit zwei in Reihe liegenden Unterbrechungsstellen, von denen die eine früher als die andere öffnet, tritt der Lichtbogen nur an der früher öffnenden Unterbrechungsstelle auf.In the above-mentioned electrical switch with two interruption points in series, from where one opens earlier than the other, the arc occurs only at the point of interruption that opens earlier on.
Die Erfindung besteht nun darin, daß die früher öffnende Unterbrechungsstelle aus hochwertigerem Material bestehende Kontakte besitzt als die später öffnende Unterbrechungsstelle. Durch diese Maßnahme wird eine erhebliche Menge des hochwertigen Materials, z. B. Kupfer oder Silber, gespart, und dadurch werden die Kosten des Schalters herabgesetzt.The invention now consists in the fact that the interruption point which opened earlier is made of higher quality Material has existing contacts than the interruption point that opens later. By this measure a significant amount of the high quality material, e.g. B. copper or silver, saved, and thereby the cost of the switch is reduced.
In der Abb. 1 ist der Erfindungsgegenstand an einem Drehschalter undIn Fig. 1 the subject of the invention is a rotary switch and
in den Abb. 2 und 3 an einem Kippschalter veranschaulicht. illustrated in Figs. 2 and 3 on a toggle switch.
Der konzentrisch auf der Schalttrommel 1 angeordnete Verbindungskontakt 2 (Abb. 1) besitzt an seinen Enden angewinkelte und auf dem Zylindermantel der Trommel 1 aufliegende Kontaktlappen 3 und 4, wovon der Kontaktlappen 3, in Richtung des Trommelumfanges gesehen, kürzer ist als der ihm gegenüberliegende Lappen 4. Wird der Schalter in Richtung des Pfeiles A bewegt, so findet zwischen dem Lappen 3 und der Kontaktfeder 5 die Unterbrechung früher statt als zwischen dem Lappen 4 und der Kontaktfeder 6. Aus diesem Grunde bestehen somit der Lappen 3 und die Kontaktfeder 5 aus hochwertigerem Material als der Lappen 4 und die zugehörige Kontaktfeder 6. Auch beim Drehen des Schalters in entgegengesetzter Richtung findet die Unterbrechung zuerst zwischen dem Lappen 3 und der Kontaktfeder 5 statt.The connecting contact 2 (Fig. 1) arranged concentrically on the switching drum 1 has at its ends angled contact tabs 3 and 4 resting on the cylinder jacket of the drum 1, of which the contact tab 3, viewed in the direction of the drum circumference, is shorter than the tab opposite it 4. If the switch is moved in the direction of arrow A , the interruption between tab 3 and contact spring 5 takes place earlier than between tab 4 and contact spring 6. For this reason, tabs 3 and contact spring 5 are made of higher quality Material as the tab 4 and the associated contact spring 6. Even when the switch is turned in the opposite direction, the interruption first takes place between the tab 3 and the contact spring 5.
Bei dem Kippschalter nach den Abb. 2 und 3 besitzt das Schaltglied 7 den Verbindungskontakt 8, dem an einem Ende ein breiter Lappen 9 und am anderen Ende ein schmälerer Lappen 10 angewinkeltIn the toggle switch according to Figs. 2 and 3, the switching element 7 has the connecting contact 8, at one end a wide flap 9 and at the other end a narrower flap 10 angled

sind. Die Kontaktfedern 11 und 12 sind beide gleich breit.are. The contact springs 11 and 12 are both equally wide.
Beim Schwenken des Schaltgliedes 7 in Richtung des Pfeiles B findet die. Unterbrechung zunächst zwischen dem schmäleren Kontakt 10 und der zugehörigen Kontaktfeder 11 statt und zeitlich danach zwischen dem breiteren Kontakt 9 und der Kontaktfeder 12. Bei diesem Schalter bestehen somit der schmälere Kontakt 10 und die Kontaktfeder 11 aus hochwertigerem Material.When pivoting the switching element 7 in the direction of arrow B takes place. Interruption initially between the narrower contact 10 and the associated contact spring 11 instead of and temporally thereafter between the wider contact 9 and the contact spring 12. In this switch, the narrower contact 10 and the contact spring 11 are made of higher quality material.
