Abstract
A control device for an electric hob has a control element placed on a support. Circular ring segmental surfaces are provided as signal generators beneath the support. On the top side and underside, the control element has numerous electrically interconnected, circular ring segmental surfaces, the lower surfaces being above the signal generators during rotation. The application of a finger to a contact surface on the control element top side is directly coupled to a sensor surface on the control element underside and can be capacitively detected by a directly facing signal generator and evaluated as a corresponding control function by a control device.
