Kontaktfeder für Hebelschalter.
Die Erfindung bezieht sich auf Hebelschalter, bei denen ein Kontaktmesser zwischen zwei gegeneinander strebende Schenkel einer hufeisenförmig gebogenen Kontaktfeder eingeschoben wird. In an sich bekannter Weise ist jener Teil der Kontaktfeder, mit welchem sie auf der Schaltergrundplatte aufliegt, nämlich die Auflagefläche der Feder, aus Festigkeitsrücksichten verstärkt.
Gegenstand der Erfindung bildet eine Kontaktfeder für einen solchen Hebelschalter, bei der die Auflagefläche in besonders zweckmässiger und einfacher Weise verstärkt ist. Erfindungsgemäss wird die Auflagefläche der Kontaktfeder durch drei Blechlappen verstärkt, von denen zwei an den Längsseiten der Auflagefläche neben den Federschenkeln, der dritte an der Schmalseite der Auflagefläche zwischen den Federschenkeln angeordnet ist. Die Lappen sind in an sich bekannter Weise nach der den Federschenkeln entgegengesetzten Seite der Auflagefläche umgefalzt.

Contact spring for lever switch.
The invention relates to lever switches in which a contact knife is inserted between two mutually striving legs of a contact spring bent in the shape of a horseshoe. In a manner known per se, that part of the contact spring with which it rests on the switch base plate, namely the contact surface of the spring, is reinforced for reasons of strength.
The subject of the invention is a contact spring for such a lever switch, in which the support surface is reinforced in a particularly expedient and simple manner. According to the invention, the contact surface of the contact spring is reinforced by three sheet metal tabs, two of which are arranged on the longitudinal sides of the contact surface next to the spring legs, and the third on the narrow side of the contact surface between the spring legs. The tabs are folded over in a manner known per se towards the side of the support surface opposite the spring legs.
