The present disclosure is a touch-sensitive input detector having an operating unit with an input surface; a support; a fastener for mounting the operating unit to the support in a vibration direction so as to be displaceable from a resting position and elastically restorable; and an actuator for stimulating the operating unit to vibrate in the direction of vibration for a haptic feedback; wherein the fastener for attaching the operating unit includes leaf spring elements, which each form a first section for attaching to the support and a second section for attaching to the operating unit, and an intermediate middle section, so that the operating unit is mounted on the support in an elastically vibratable manner, and which are arranged at a distance from each other by the middle section, wherein at least one section from first section and second section is attached by a form-fit seat, such as overmolding.

A switching device for detecting a voltage interruption at a control unit in a motor vehicle, with a nonvolatile memory for storage of calibration data for an actuator that can be adjusted by the control unit and a drive unit. The control unit is supplied with an internal voltage through a voltage regulator and a bistable multivibrator is connected ahead of the voltage regulator in the external voltage supply of the control unit, and, whereby a microcomputer is connected with the multivibrator and is integrated in the control unit.

The invention concerns a motor controller for a motor with a feedback potentiometer, preferably for central air valve actuation. In the field of climate control, for example for utility vehicles and motor vehicles, the air ducts in heating, air conditioning and/or ventilation systems have valves to control the flow of air or water. These valves are adjusted either mechanically, e.g. by Bowden cables or flexible shafts, or using motors. It is proposed that a continuous rotation potentiometer be employed as a feedback potentiometer and specially designed control electronics be used to control a motor with the continuous rotation potentiometer. In the control electronics for the motor controller, an angular difference between an adjusted control potentiometer and the motor feedback potentiometer is determined in order to determine therefrom the shortest adjustment path to the chosen setpoint position for the motor when the angular difference is greater than 180 degrees.
