Abstract

The invention relates to capacitive control and display device (1) for a household device comprising a display window (2) with a touch-sensitive control surface (5), a display symbol (7) being mounted on the display window (2). The device also comprises a lighting element (11) for emitting light for lighting the display symbol (7) and a capacitive sensor electrode (9) as part of a touch capacitor, the sensor electrode being arranged at a distance from the control surface (5) so that the capacitance of the touch capacitor can be changed when the control surface is touched (5). The sensor electrode (9) is arranged on a printed circuit board (8), and an element (12) is arranged between the control surface (5) and the sensor electrode (9), the element consisting of an elastic and electrically-insulating material.
