Description

Es sind Schalter bekannt, bei denen als Druckelement eine am Rande eingespannte gewölbte Platte von kreisförmiger Gestalt vorgesehen ist.There are switches known in which the pressure element is a clamped at the edge domed plate of circular shape is provided.

Gemäß der Erfindung ist der Rand der Blechplatte derart umgebördelt, daß die Umbördelung seitlich aus dem Gehäuse heraus ragt. Durch seitlichen Druck auf den umgebördelten Rand wird die Platte wieder in ihreAccording to the invention, the edge of the sheet metal plate is flanged in such a way that the flanging protrudes laterally from the housing. By lateral pressure on the flanged Edge will put the plate back in its

ίο Ausgangslage zurückgebracht, nachdem sie durch einen zentralen Druck zum Durchschnappen gebracht worden ist. Um die Spannungsdifferenz zwischen der oberen und unteren Stellung des Bleches ausgleichen zu können, ist ihr Rand in regelmäßigen Abständen durch Einschnitte in Zungen zerlegt. Des weiteren kann das Blech, um die Spannung zu erhöhen,, mit einer Isolierkunstharzmasse überzogen sein.ίο brought back to starting position after they has been made to snap through by a central pressure. To determine the voltage difference between the top and To be able to compensate for the lower position of the sheet, its edge at regular intervals cut into tongues by incisions. Furthermore, the sheet metal to increase the tension increase ,, be coated with an insulating synthetic resin compound.

In der Zeichnung ist der Schalter in zwei Abbildungen dargestellt, und zwar zeigt Abb. 1 einen Grundriß und Abb. 2 einen Querschnitt desselben.In the drawing, the switch is shown in two images, namely Fig. 1 a plan view and Fig. 2 a cross section of the same.

Es bedeutet: α den Schaltersockel, b das Blech bzw. den Blechrand, b1 die zu drückende Mitte des Bleches, c und c1 sind die Kontaktstücke, d ist eine Öffnung in der Schalterkappe, e sind die Schlitze im Blechrand.It means: α the switch base, b the sheet metal or sheet edge, b 1 the center of the sheet to be pressed, c and c 1 are the contact pieces, d is an opening in the switch cap, e are the slots in the sheet metal edge.

Die Bedienungsweise ist folgende:The operation is as follows:

Man drückt beim Einschalten auf die Mitte b1 des Bleches und bringt dadurch die Kontakte c und c1 in Berührung, schließt also den Stromkreis. Drückt man dann in Pfeilrichtung auf den Rand δ des Bleches, so bewegt sich das Blech mit dem Kontakte wieder nach oben, und der Stromkreis ist unterbrochen.When switching on, one presses on the middle b 1 of the sheet metal and thereby brings the contacts c and c 1 into contact, thus closing the circuit. If you then press the edge δ of the sheet in the direction of the arrow, the sheet with the contacts moves upwards again and the circuit is interrupted.
