Control device for an electrical appliance
First Claim
1. A control device for an electrical appliance, said control device having a control element with a control element underside having a first surface area and a second surface area, said control element being constructed for resting in movable and removable manner with said control element underside on a mounting surface having a planar mounting surface top side by means of a retaining force, wherein said control element underside in said first surface area is constructed corresponding to said planar mounting surface top side for a stable position of said control element in a tilt-stable basic position, said retaining force assisting said basic position, said first surface area being surrounded by said second surface area having a convexity diverging from a course of said first surface area and retreating from said mounting surface top side in such a way that said control element is tiltable away from said basic position in case of engagement towards said mounting surface into a tilted position, detection means being provided for detecting said position of said control element in said basic position or in said tilted position and for triggering a control function.

Abstract
An operator control device for an electric heating apparatus comprises a control element, which rotatably and removably rests on a mounting surface and is held by a magnetic retaining force. The control element has a bottom side facing the mounting surface while the mounting surface has a planar top side facing the control element. The bottom side is embodied in a flat manner in a first sub-area to keep the control element in a stable basic position, an effect that is supported by the magnetic retaining force. Said first sub-area is surrounded by an adjacent second sub-area that encompasses a receding curvature such that the control element can be tilted from the basic position while the contact to the mounting surface is maintained. Detection sensors are provided for detecting the position of the control element in the basic position or another position in order to trigger a control function.
