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