Abstract
A control device for an electrical appliance has a control panel wherein a plurality of capacitive sensor elements for a capacitive proximity switch are arranged under the control panel and are arranged in a continuous row, in order to form an elongated slider for operation by application of a finger and drawing the finger over them. The sensor elements are all identical and have a rectangular shape, wherein they are each arranged with one of their first sides facing one another and with all of their sides parallel to one another. They are aligned in the same way with respect to the continuous row, wherein the first sides are rotated through an angle of between 46° and 75° to form the row along which the sensor elements are arranged.
