Operating device with at least one pressure switch

摘要

The device has a piezoelectric film (24) connected with a carrier element (20) by an adhesive layer (22). The piezoelectric film is provided with a sensor field (23) corresponding to a push-button switch. A cover layer (26) is turned towards a user side, and is connected with the piezoelectric film by another adhesive layer. A fastening element (30) fastens the device to a control panel. A printed circuit board (28) is completely inserted into a recess of the carrier element.
