Abstract:
A capacitive proximity switch includes an electrically conductive sensor area, which is covered by an electrically-insulating cover plate, as part of a capacitor having a capacitance which varies as a result of proximity. An associated evaluation circuit is provided, and an electrically-conducting body, via which the sensor area is connected to the evaluation circuit and which is arranged between the electrically-insulating cover plate and a mount disposed at a distance therefrom. A domestic appliance includes such a proximity switch. At least one electronic component of the evaluation circuit is arranged on the mount such that it protrudes into a cavity, which is surrounded by the electrically conductive body.
