Abstract

An arrangement for the control of electrically controllable appliances, particularly electric cookers proposes for each cooking point an operating element magnetically held in contactless manner on the top or front of a plate, e.g. a glass ceramic plate. Below or behind the plate is located a magnet, which magnetically secures the operating element, which can in this position be rotated in contactless manner sensors are operated, which are used for changing the control of the cooking point. Both the control and the fixing of the operating element take place in contactless manner. The plate requires no openings, passages, depressions, etc. The operating elements can be removed on overcoming the magnetic holding force. This removal can be utilized for the complete disconnection of the cooker.
