KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft einen elektrischen Starkstromschalter mit zwei fest gegeneinander gepreßten Kontakten, zwischen die beim Ausschalten zwecks Funkenlöschung eine isolierende Platte geschoben wird. Bei derartigen Schaltern können die Kontaktstellen im Laufe der Zeit mit Isolationsmasse, die von der zwischentretenden isolierenden Platte abgeschliffen wird, überzogen werden, wodurchThe present invention relates to an electrical power switch with two fixed against each other Pressed contacts, between which an insulating plate is pushed when switching off for the purpose of spark extinction. With such In the course of time, switches can protect the contact points with insulating material from the insulating plate between them is abraded, coated, whereby

ίο der Übergangswiderstand erhöht wird, oder es kann sich die Isolierplatte mit Staub überziehen, wodurch in der Ausschaltestellung eine leitende Brücke gebildet werden kann.ίο the contact resistance is increased, or it the insulating plate can become covered with dust, causing a conductive bridge can be formed.

Um dies zu vermeiden, wird gemäß der Erfindung die isolierende Platte so angeordnet, daß sie die Kontakte nicht unmittelbar, sondern mittels Ansätze an den Kontakten auseinanderdrückt und auch in der Äusschalt-Stellung die Kontaktflächen, zwischen denen sie liegt, nicht berührt. Die Ansätze können aus isolierendem Material gebildet und auch mit Rollen versehen sein, um die Reibung herabzumindern.To avoid this, according to the invention, the insulating plate is arranged so that it does not push the contacts apart directly, but by means of approaches to the contacts and also in the switch-off position the contact surfaces between which it lies does not touch. The approaches can Made of insulating material and also be provided with rollers to reduce friction to diminish.
