Capacitive proximity switch

2012 
A touch and visually high-quality position-sensitive capacitive proximity switch (11) has a with electrodes sectors (18) deposited ceramic disc, which is preferably around the bottom (13) of a drawn one piece in the ceramic injection molding process shallow pot (12) is. Defined surface structures of the operating surface (14) on the axially accessible from the outside pot base (13) serve, in particular tactile, by illuminated regions of the pot bottom (13) of an optical user guidance. in the pot (12) is surrounded easy turned back from the electrode sections (18), this sensor circuit (16) by an electrical conductor (27) for discharging electrostatic charges, which is preferably designed in the radial installation area across as an elastic buffer.
