摘要： A sensor switch comprises a first sensor electrode and a second sensor electrode at least partially surrounding the first sensor electrode. An evaluation and control circuit is configured to generate a switch output signal if a first sensor electrode attenuation signal indicates a high attenuation, a second sensor electrode attenuation signal indicates a low attenuation and a cross coupling signal from the first to the second electrode indicates a low cross coupling.

摘要： A sensor switch with water suppression comprises a sensor electrode and a photodiode connected to an evaluation circuit. The evaluation circuit generates a capacitive sensor signal indicative of an electrically conductive object in the proximity of the sensor switch and an optical sensor signal indicative of an object impermeable to light in the proximity of the sensor switch. The capacitive sensor signal and the optical sensor signal are correlated to generate an output signal.

摘要： A sensor button includes at least one capacitive sensor electrode for detecting the presence of a hand and/or a finger in a capacitive detection space and at least one optical sensor for detecting at least one hand and/or finger gesture within a optical detection space. The optical detection space is at least partially more distant from the sensor button than the capacitive detection space. This al-lows to detect gestures by two independent detectors with a movement within or between spaces.
