Abstract
A control circuit arrangement for controlling the after-running of an operating device in a motor vehicle is described, with which after shutting off the ignition the operating device is provided with voltage for a certain time interval by an associated voltage regulator and a switching means including a transistor. The shut off of the voltage provided to the operating device occurs by changing the input potential of the voltage regulator. Otherwise without the arrangement of the invention an external or internal relay is needed to switch off the voltage. In various embodiment the potential change at the control input of the voltage regulator can be controlled by electronic hardware devices or by a microprocessor under the control of software.
