Abstract
A control device for an electrical cooking appliance having a case, a bowl and a heating element associated with the bowl. The control device includes a rotatable part mounted for rotation about an axis and supporting elements having indicia and/or arranged to control a power switch and/or to modify a position of a setting element for a temperature or pressure controller, and/or to act through a mechanism on a lock for a lid, a control button mounted for movement in translation parallel to the axis between a rest position, where it is at least approximately flush with an external face of the case, and a depressed position where it is at least partly retracted into the case, first camming surfaces on a surface of the rotatable part that is concentric with the axis, second camming surfaces on a surface of the button that is concentric with the axis and located to interact with the first camming surfaces to provoke a first rotation of the rotatable part during depression of the button from its rest position to its depressed position, third camming surfaces on a surface of the rotatable part that is concentric with the axis, the third camming surfaces being offset with respect to the f…
