<p>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.</p> |
