Abstract

Der elektrische Schalter (2) ist insbesondere für Haushaltsgeräte vorgesehen und weist eine Kontaktfeder (4) sowie ein auf die Kontaktfeder (4) einwirkendes Schaltelement (14), beispielsweise einen Drehknopf, auf. Der Kontaktfeder (4) ist ein Gegenkontakt (12) zugeordnet, welcher auf einer Leiterplatte (8) aufgebracht ist und eine Carbonschicht aufweist. Durch die Carbonbeschichtung ist eine hohe mechanische Beständigkeit bei vergleichsweise geringen Kosten erzielt.

Figure imgaf001
The electrical switch (2) is provided in particular for household appliances and has a contact spring (4) and a switching element (14) acting on the contact spring (4), for example a rotary knob. The contact spring (4) is associated with a mating contact (12), which is applied to a printed circuit board (8) and has a carbon layer. The carbon coating achieves high mechanical resistance at comparatively low cost.
