OPERATING UNIT FOR ELECTRICAL APPLIANCES
First Claim
1. An operating plate for operation of a household appliance, comprising an electrically conductive plate with at least one operating element arranged at or in the plate,wherein the operating element comprises at least one first electrode and at least one second electrode,wherein the at least one second electrode constitutes a coupling capacitance with ground,wherein the at least one first electrode is capacitively couplable with the electric conductive plate,wherein operation of the operating element is capacitively transmitted to a receiving device, andwherein a load of the receiving device corresponds to the ground-coupling capacitance of the at least one second electrode.

Abstract
The invention relates to an operating unit for operation of household appliances, especially for operation of a hob or a washing machine. In this connection, operating elements are arranged on an electrically conductive operating plate, by which they are capacitively coupled with a receiving device that is located in or at the household appliance. Transmission of the operation of the operating elements to the receiving device takes place by detection a load change in the receiving device, the load change being caused by the operating elements.
