  • Patent number: 7265747
    Abstract: An operating element can be used to operate or control a household appliance, for example a cook top heating element. A seven-segment display is arranged beneath a cover in the region of a contact surface. A light source and a light receiver are arranged inside respectively of four LED elements of the seven-segment display in two channel-type openings oriented towards the contact surface. The insertion of the light source and receiver into the openings enables the contact surface to the positioned directly above the display and shields the light receiver from scattered light. Placement of a finger on the contact surface results in light from the light source to be reflected and detected by the light receiver, and thus effect control of the household appliance.
