Die Löschwirkung einer derartigen Schaltereinrichtun- wird durch die Erfindun- weiter II ZD O'csteigert, indem bei dem Gegenstand der Erfindung von der bei Schaltern an sich 1)ekannten Doppelströmung über den Lichtbogen hinweg Gebrauch gemacht wird. Zu diesem Zweck besitzt erfindungsgemäß das bewegliche Pumpenglied außer dem dein ruhenden Kontakt zugelzehrten Piiii-ipeii.iusl,-iI') auch noch cinen 7weiten in entgegengesetzter Richtung verlaufenden, den Schaltstift umschließenden Ausströrnkanal, sa daß das Löschmittel den Lichtbogen nach beiden. Fußpunkten hin bespült. Die Einrichtung ge- stattet ein besonders rasches Entweichen der in der Umgebung des Lichtbogens entstehenden Gase und eine gründliche Reinigung der Lichtb,o,- "cnbalin, ohne ein Nachströmen von Ionen und Metalldämpfen von dem einen zum anderen Pol befürchten zu müssen.The extinguishing effect of such a switch device is increased by the invention II ZD O'c, in that the subject matter of the invention makes use of the double flow across the arc, which is known per se in switches 1). For this purpose, according to the invention, the movable pump element has, in addition to the piiii-ipeii.iusl, -iI '), which is closed to the resting contact, also a 7-wide discharge channel running in the opposite direction, surrounding the switching pin, so that the extinguishing agent discharges the arc after both. Washed down towards the foot points. The device allows a particularly rapid escape of the gases arising in the vicinity of the arc and a thorough cleaning of the lightb, o, - "cnbalin, without having to fear a flow of ions and metal vapors from one pole to the other.

In der Zeichnung ist ein Ausführungsbcispiel für den Erfindungsgegenstand dargestellt. In einem Schaltergehäuse i is.t an dem Bodendeckel 2 ein Kontakt 3 befestigt, mit dem der I#:.c>ntal,-tstift4 den Stromschluß herstellt. Der Kontaktstift -leitet durch eincil Pumpenzylindcr 5, der über einen festen K.o1-ben 6 bewegt wird. In dem Zylinder 5 ist oberhalb der Auslaßöffnung i i eine Zylinderwand7 eingebaut, die den Kontaktstift umhüllt und mit dem Kontaktstift einen Ringkanal bildet. Beim Ausschalten geht der Kontaktstift in die in der Zeichnunu angelb 1.1 deutete Lage, ohne die Pumpvoirichtung zu betätigen. Erst von dem Augenblick an, in dem der Kontaktstift 4 die beiden Auslaßöffnungen 8, 11 freigelegt hat, wird der Pumpenzylinder 5 durch den Bund 9 auf dein Kontaktstift mitgenommen, und das Löschmittel unispült den 1,icliti)Ol(#'011 Mit AvOi in entgegengesetzter Richtung verlaufenden und ZD ZD durch Pfeile dargestellten Tciis,(i-öiieli. Der obere, den Kontakt einhüllende Tuilstr1-)in ver-Mißt die Punipeinrichtung durch einzelne im Zylinderumfan.- \-erteilt angeordnete Üffnurtgen. 10. The drawing shows an exemplary embodiment for the subject matter of the invention. A contact 3 is attached to the base cover 2 in a switch housing i, with which the I #: c> ntal, -tpin4 establishes the current circuit. The contact pin-leads through a pump cylinder 5, which is moved over a fixed connector 6 . In the cylinder 5 , a cylinder wall 7 is installed above the outlet opening ii, which surrounds the contact pin and forms an annular channel with the contact pin. When switching off, the contact pin goes into the position indicated in the drawing 1.1, without actuating the pump device. Only from the moment when the contact pin 4 has exposed the two outlet openings 8, 11, the pump cylinder 5 is carried along by the collar 9 onto your contact pin, and the extinguishing agent unrinses the 1, icliti) oil (# '011 With AvOi in Tciis running in the opposite direction and ZD ZD represented by arrows, (i-öiieli. The upper Tuilstr1- enveloping the contact) in measures the Punip device by individual transitions arranged in the circumference of the cylinder .
