Abstract

Die Erfindung betrifft eine Kontaktfeder-Einheit (1) für elektrische Schaltfunktionen mit einer metallischen Kontaktplatine (2), die ein Basisteil (3) mit wenigstens einem einstückig mit diesem ausgebildeten Kontaktarm (5) aufweist, und einem elektrisch nichtleitenden Rahmenteil (7), in dem das Basisteil (3) der Kontaktplatine (2) fest aufgenommen ist. Um Verbiegungen und Beschädigungen der Kontaktarme (5) der Kontaktfeder-Einheiten (1) bei Verwendung als Schüttgut zu vermeiden, ist zumindest eine der Längsseiten (12) und das vordere Ende (9) des Kontaktarms (5) von wenigstens einem mit dem Rahmenteil (7) einstückig ausgebildeten Rahmenschenkel (8) umgeben, wobei das vordere Ende (9) des Kontaktarms (5) lösbar im Rahmenschenkel (8) arretierbar ist

Figure 00000001
The invention relates to a contact spring unit (1) for electrical switching functions with a metallic contact board (2), which has a base part (3) with at least one contact arm (5) formed integrally therewith, and an electrically non-conductive frame part (7), in which the base part (3) of the contact board (2) is firmly received. In order to avoid bending and damage to the contact arms (5) of the contact spring units (1) when used as bulk material, at least one of the long sides (12) and the front end (9) of the contact arm (5) is connected to at least one with the frame part ( 7) surrounded in one piece frame legs (8), the front end (9) of the contact arm (5) being releasably lockable in the frame leg (8)
