Abstract

Die Erfindung betrifft einen beleuchtbaren Drehknopf (1). Der Drehknopf (1) weist eine drehbar angeordnete Handhabe (2), eine mit der Handhabe (2) fest verbundene und mit dieser drehbare erste Trägerplatte (10), eine feststehende zweite Trägerplatte (6), Schleifer (16, 17) zur Herstellung einer elektrischen Verbindung zwischen den Trägerplatten (6, 8) und eine elektrische Lichtquelle (11) auf. Erfindungsgemäß ist die elektrische Lichtquelle (11) auf der ersten Trägerplatte (10) angeordnet und wird über die Schleifer (16, 17) mit einer Betriebsspannung versorgt. Mit einer einzigen Lichtquelle (11) wird somit eine gleichmäßige Beleuchtung einer Markierung oder eines Symbols der Handhabe (2) unabhängig von der Position der Handhabe (2) erreicht.

The invention relates to an illuminated knob (1). The rotary knob (1) has a rotatably arranged handle (2), a first support plate (10) fixedly connected to the handle (2) and rotatable with it, a fixed second support plate (6), grinder (16, 17) for producing a electrical connection between the carrier plates (6, 8) and an electrical light source (11). According to the invention, the electrical light source (11) is arranged on the first carrier plate (10) and is supplied with an operating voltage via the grinders (16, 17). Uniform lighting of a marking or a symbol of the handle (2) is thus achieved with a single light source (11) regardless of the position of the handle (2).
