Abstract
A control mechanism for an electrical appliance comprises a deformable or elastic control panel, for example, embodied as a frame of an electric cooking hob. Several piezo sensor elements are arranged under the control panel. The piezo sensor elements are arranged on the rear side of a printed circuit board, the opposite front side of said printed circuit board being arranged or fastened to the underside of the control panel in a planar manner. By determining the difference of the signals of the sensor elements arranged next to each other, it is possible to accomplish an extremely good and safe evaluation of a location where a finger is placed with light pressure on the control panel.
