Description

Die Erfindung bezieht sich auf einen Installationsschalter, der hauptsächlich für Lichtinstallationen bestimmt ist und bei dem die Schalterachse aus Isoliermaterial besteht.
Die bisher verwendeten Schalter hatten den großen Nachteil, daß die zwischen den festen Kontakten und den Schleifkontakten auftretenden Abreißfunken ein Anfressen der Kontakte bewirkten, wodurch die Lebensdauer der Schalter beträchlich herabgesetzt wurde.
The invention relates to an installation switch which is mainly intended for light installations and in which the switch axis is made of insulating material.
The switches used hitherto had the major disadvantage that the tear-off sparks occurring between the fixed contacts and the sliding contacts caused the contacts to be pitted, which considerably reduced the service life of the switches.

Dieser Übelstand wird gemäß der Erfindung dadurch vermieden, daß man an den festen Kontakten, mit denen S-förmige doppelte Schleifkontakte zusammenwirken, Schnappfedem anbringt, zwischen denen zwei zusätzliche auf der Achse befestigte Kontaktbügel verstellt werden können.This drawback is avoided according to the invention in that one of the fixed Contacts with which S-shaped double sliding contacts interact, snap springs attaches, between which two additional contact brackets attached to the axis are adjusted can be.

In der Zeichnung ist ein Ausführungsbeispiel eines Schalters gemäß der Erfindung dargestellt. Es zeigen Abb. χ den Unterteil des Schalters von oben, Abb. 2 den Handgriff, Abb. 3 die Gesamtanordnung in schaubildlicher Darstellung, teilweise geschnitten.In the drawing, an embodiment of a switch according to the invention is shown. Fig. Χ shows the lower part of the switch from above, Fig. 2 the handle, Fig. 3 shows the overall arrangement in a diagrammatic representation, partially in section.

An dem isolierten Gehäuse 1 sitzen die festen Kontakte 3. Die isolierte Achse 2 ist mit einem radialen symmetrischen Schlitz4 versehen, der die Achse von oben bis zum Sitz des S-förmigen Federkontaktes 5 durchsetzt und in den dieser eingesetzt ist.The fixed contacts 3 are seated on the insulated housing 1. The insulated axis 2 is with provided with a radial symmetrical slot4 that runs the axis from the top to the seat of the S-shaped spring contact 5 penetrated and in which this is inserted.

Der Handgriff 6 (Abb. 2) ist mit einer exzentrischen Rast 6' versehen, in die eine auf der Achse angebrachte Sperrfeder 8 eingreift. Diese dient zur Übertragung der drehenden Bewegung des Griffs in der einen Drehrichtung, während sie bei einer Drehung des Griffs in der anderen Richtung über die Rast 6' hinweggleitet, so daß die Schalterachse nicht mitgenommen wird.The handle 6 (Fig. 2) is provided with an eccentric detent 6 'into which one on the Axle attached locking spring 8 engages. This is used to transmit the rotating movement of the handle in one direction of rotation, while one rotation of the handle in the other direction slides over the detent 6 'so that the switch axis is not entrained will.

An den festen Kontakten 3 sind parallel zueinander laufende Schnappfedern 7 befestigt, die mit ihrem freien Ende in das Gehäuse des Schalters eingreifen. Zwischen diesen Federn sind zwei auf der Achse 2 befestigte zusätzliche Kontaktbügel 9 angebracht, die bei geöffnetem Schalter die in Abb. 1 gezeigte Lage einnehmen und bei geschlossenem Schalter die in Abb. 3 gezeigte Lage.Snap springs 7 running parallel to one another are attached to the fixed contacts 3, which engage with their free end in the housing of the switch. Between these feathers are two attached to the axis 2 additional contact clip 9 attached, which at take the position shown in Fig. 1 with the switch open and with the switch closed the position shown in Fig. 3.

Das Öffnen und Schließen des Stromes wird somit gewissermaßen durch die Kontaktbügel 9 und die Federn 7 bewirkt, während der S-förmige Schleifkontakt 5 die Abreißfunken aufnimmt, so daß die eigentliche Schaltvorrichtung von diesen nicht angefressen wird.The opening and closing of the current is thus to a certain extent controlled by the contact clip 9 and the springs 7 causes, while the S-shaped sliding contact 5 picks up the tear-off sparks, so that the actual switching device is not eaten by these.
