Operating unit with capacitive touch screen and home appliance

The invention relates to an operating device that is electrically isolated from a ground potential, with a capacitive touch screen and a household appliance. The operating unit (101) comprises a capacitive touch screen (102) and an electrode of a capacitor-forming element (103) is formed such that a capacitive coupling to the ground potential results in operation of the operating device (101) such that the capacitive touchscreen (102) is operated. Using, for example, for process control.
