A motor vehicle control device having a switch-on and switch-off function for an electrical load to be controlled by the motor vehicle control device, the motor vehicle control device comprising:
- an electronic switching element configured to be disposed in a supply voltage path of the electrical load;
- and
- a control unit for controlling the electronic switching element, wherein the control unit is configured to provide a control signal for switching the electronic switching element based on an input signal, and wherein the control unit comprises a resistor connected to the supply voltage path and a current control means connected in series therewith for generating a predefinable voltage difference at the resistor as the control signal for the electronic switching element.
