Description
Die vorliegende Erfindung bezieht sich auf einen Schalter, in welchem der Kontakt in bekannter Weise durch Metallkugeln hergestellt wird. Erfindungsgemäß sind die Kugeln in Vertiefungen des Sockels, die sich gegenüber der unteren Stirnseite der Schaltscheibe befinden, starr gelagert, und die entsprechenden Vertiefungen der Schaltscheibe sind durch Rinnen, die in der Drehrichtung ansteigen, miteinander verbunden. The present invention relates to a switch in which the contact is known Way is made by metal balls. According to the invention, the balls are in recesses of the base that are opposite to the are located on the lower face of the switching disk, rigidly mounted, and the corresponding depressions of the switching disc are connected to one another by grooves that rise in the direction of rotation.
Die Metallkugeln g befinden sich in den Kugellagern e (Abb. ι und 2), welche in dem Sockel des Schalters, der aus Porzellan oder einer anderen Isoliermasse besteht, mittels Schraubenmuttern h befestigt sind. Diese Schraubenmuttern h dienen gleichzeitig zur Befestigung der Stromzuleitungsdrähte. In der Schaltscheibe d (Abb. 1 und 4), die ebenfalls aus Isoliermasse hergestellt ist, befinden sich vierThe metal balls g are in the ball bearings e (Fig. Ι and 2), which are fastened in the base of the switch, which is made of porcelain or some other insulating material, by means of screw nuts h. These nuts h also serve to fasten the power supply wires. In the switching disk d (Fig. 1 and 4), which is also made of insulating compound, there are four
ao Vertiefungen 0, in welche die Kugeln bis zur Hälfte hineinpassen. Die vier Vertiefungen 0 der Schaltscheibe sind durch Kanäle m verbunden. Diese Kanäle sind von Vertiefung zu Vertiefung steigend angeordnet. Je nachdem der Schalter als Aus-, Wechsel- oder Serienschalter gebraucht wird, werden zwei oder drei Vertiefungen 0 durch Nieten f (Abb. 1) und die Kontaktbrücke χ (Abb. 5) miteinander verbunden. Die Schaltscheibe d hat in der Mitte ein unrundes Loch n, durch welches der Bolzen ζ (Abb. 1) hindurchgeht; dieser trägt im oberen Teil den Schaltergriff a. ao wells 0, into which the balls fit halfway. The four recesses 0 of the switching disk are connected by channels m . These channels are arranged rising from recess to recess. Depending on whether the switch is used as an off, changeover or series switch, two or three recesses 0 are connected to one another by rivets f (Fig. 1) and the contact bridge χ (Fig. 5). The switching disk d has a non-circular hole n in the middle, through which the bolt ζ (Fig. 1) passes; this carries the switch handle a in the upper part.
Die Wirkungsweise des Schalters ist folgende : Durch Drehen des Schaltergriffs α wird die Schaltscheibe d' nach rechts gedrängt, gleitet durch die steigend angeordneten Kanäle m über die Metallkugeln g nach oben (Abb. 3) und wird durch die Druckfeder c beim Erreichen der nächsten Vertiefungen nach unten gedrückt. Ein Linksdrehen des Schalters ist durch die einseitig ansteigenden Kanäle m ausgeschlossen.The mode of operation of the switch is as follows: By turning the switch handle α , the switching disk d 'is pushed to the right, slides through the ascending channels m over the metal balls g upwards (Fig. 3) and is activated by the compression spring c when it reaches the next indentations pressed down. Turning the switch to the left is prevented by the channels m rising on one side.
Zur Befestigung des Schalters dienen die Öffnungen i (Abb. 2). The openings i (Fig. 2) are used to fasten the switch.
Bei größeren, sogenannten [Kraftschaltern kann eine mehrfache Kugellagerung angeordnet werden.In the case of larger, so-called power switches, multiple ball bearings can be arranged will.
