Es gibt Schalter, deren Druckknöpfe nur in einem entsprechend großen Loch in der Schalterkappe Führung haben. In Abb. ι und 2 ist ein solcher Schalter dargestellt. Die Schalterkappe a, in welcher die Druckknöpfe b und c Führung haben, besteht meistens aus Porzellan o. dgl. Infolgedessen weichen selbst bei gleichmäßiger Massenfabrikation die Durchmesser der Führungslöcher voneinander ab. Es ergibt sich deshalb von selbst, daß die Druckknöpfe, je mehr Luf.t sie in diesen Löchern haben, um so schiefer stehen. Ein anderer Nachteil dieser Anordnung besteht darin, daß beim Abnehmen der Schalterkappe α von dem an der Wand befestigten Schaltersockel d die losen Druckknöpfe b und c zur Erde fallen.There are switches whose push buttons only have a guide in a correspondingly large hole in the switch cap. In Fig. Ι and 2 such a switch is shown. The switch cap a, in which the push buttons b and c have a guide, is mostly made of porcelain or the like. As a result, the diameters of the guide holes differ from one another even with uniform mass production. It therefore goes without saying that the more air they have in these holes, the more crooked the press studs are. Another disadvantage of this arrangement is that when the switch cap α is removed from the wall-mounted switch base d, the loose push buttons b and c fall to the ground.
Die geschilderten Nachteile werden durch die vorliegende Erfindung in Wegfall gebracht. Wie das in Abb. 3 und 4 dargestellteThe disadvantages outlined are eliminated by the present invention. Like the one shown in Figs. 3 and 4
Ausführungsbeispiel zeigt, erhalten die Ansätze der Knöpfe b und c im Innern der Schalterkappe α gut passende Führungen e und f, die mit Durchbrüchen oder Aussparungen g und h versehen sein können, in welchen sich der Hebelmechanismus des Schalters frei bewegen kann. Auf diese Weise erhalten die Knöpfe so lange Führungen, daß sie sich fast geradlinig bewegen.Embodiment shows, get the approaches of the buttons b and c inside the switch cap α well-fitting guides e and f, which can be provided with openings or recesses g and h in which the lever mechanism of the switch can move freely. In this way, the buttons are given so long guides that they move almost in a straight line.
ίο Um die Knöpfe gegen das Herausfallen zu sichern, werden an den freien Enden der Führungen e und f vorspringende Teile angebracht. Bei dem in Abb. 3 und 4 dargestellten Ausführungsbeispiel sind die vorspringenden Teile i und k Lappen eines aus Isoliermaterial hergestellten, an einer Stelle offenen Ringes I, welcher sich gegen die Innenwandung der Schalterkappe α legt. Die beiden zusammenstoßenden Enden des Ringes / sind als Wulste m und η ausgebildet, wodurch ein gutes Festsitzen des Ringes I in der Schalterkappe α gewährleistet wird.ίο To prevent the buttons from falling out, protruding parts are attached to the free ends of guides e and f. In the embodiment shown in Fig. 3 and 4, the projecting parts i and k are tabs of a ring I made of insulating material, open at one point, which lies against the inner wall of the switch cap α. The two abutting ends of the ring / are designed as beads m and η , whereby a good fit of the ring I in the switch cap α is guaranteed.
