  • the invention generally relates to a switch and / or turntable with at least one control knob, which is displaceable relative to a control panel surrounding the aperture of an operating position in a lowered position and vice versa.
  • This type of switch or turntable is used regularly in motor vehicles with the aim of fulfilling the so-called Kopf Stammtschkriterium. Accordingly, it is only permissible for the control knob to project from the surrounding bezel, trim, dashboard, or system panel of a motor vehicle by a legal maximum distance measure to minimize the risk of injury in the event of a head impact. In order nevertheless to enable convenient operability and easy gripping of the operating head, it is known to support the control knob in a yielding manner or to make it deformable. Furthermore, the aforementioned, slidably mounted control knobs are known, which latch in the operating position and reach the sinking position at the head impact by breaking a predetermined breaking point.
