ABSTRACT:
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.
