Abstract: A circuit configuration for a capacitive touch switch contains at least one sensor circuit with a capacitive sensor element which changes its capacitance value when touched, and an evaluation circuit which is supplied with an output signal from the sensor circuit in order to determine whether the capacitive sensor element is actuated or not. The at least one sensor circuit has a capacitance which is connected in parallel with the capacitive sensor element, and a capacitance/frequency converter which is connected to the parallel circuit containing the capacitance and the capacitive sensor element and generates, at its output, a frequency signal whose frequency depends on the total capacitance of the parallel circuit containing the capacitance and the capacitive sensor element. The evaluation circuit may thus use a significant change in the frequency of the output signal from the sensor circuit to deduce, in a simple manner, that the capacitive sensor element has been touched.

Abstract: In order to enable an electrical appliance, in particular for a domestic appliance, an economically produced control panel for different models of the appliance is provided. The control panel has a sensor film forming a switch panel with a plurality of individual switch zones. Each of the switch zones can be selected independently of each other. A specific selection of the switch zones is activated depending on what devices are fitted in the electrical appliance. In addition, the sensor film is assigned an externally accessible keypad having a plurality of individual visually identified button zones assigned to each of the activated switch zones. The sensor film is in particular a film having a printed piezo-layer from which the individual switch zones are formed.
