A control unit (1) for switching and controlling functions (6) of household appliances has a continuous control surface (2) with operational areas (3) and a printed film (5). Several piezosensors (4) are arranged on a back of a plate forming the control surface (2), connected firmly and rigidly to the plate. The piezosensors (4) can be located in a film packet (9), for example, through which the piezosensors (4) are electrically connected to a processor (12). Through an offset arrangement of the piezosensors (4) in a matrix pattern direct illumination or back lighting of the printed film (5) can be achieved, thereby improving an operator's visual recognition while permitting accurate recognition of a function by the processor (12). An input filter (15) prevents operator error due to unintentional actuation of the control unit.

[ The invention claimed is:] [1.] A control unit for switching and controlling household appliances, particularly for use with large household appliances, said control unit including:a plate that is stable in form and having a control surface without perforations formed thereon for being touched, said control surface including operational areas associated with functions to be activated by said control unit;separate individual pressure-sensitive sensors firmly coupled to the plate for generating simultaneous electrical signals in response to pressure being applied at a pressure point on the control surface, relative intensities of the respective signals, each depending upon a location of the sensor which created the signal relative to the pressure point on said control surface;a processor coupled to the sensors for receiving and evaluating the signals and for determining a location of the pressure point on the control surface in relationship to the operational areas and thereby determining a function to be carried out by the control unit.
