Abstract
An arrangement for controlling electrically controllable appliances, such as electric cookers, has at least one manually operable control element placed on an outside of a plate, e.g. a glass ceramic plate of an electric cooker, which is secured by a magnetic holding device in non-contacting magnetic manner on the plate. A sensor device determines the position and/or position change of the control element and an associated control device, in order to set different operating modes of the appliance. The control element is constructed as a sliding key automatically returning to a rest position and which is displaceable in at least one displacement direction along the plate. Such sliding keys can be operated in a particularly easy manner and are well adapted to an at least partial digital processing of the sensor signals to controlling signals.
