HMI device with capacitive touch screen and household appliance

摘要

The invention relates to an operating device which is galvanically isolated from a ground potential, with a capacitive touch screen and a household appliance. The operating device (101) comprises a capacitive touchscreen (102) and an electrode of a capacitor forming element (103) which is designed such that during operation of the operating device (101) results in a capacitive coupling to the ground potential such that the capacitive Touchscreen (102) is operable. Use, for example, for process control.
