1. A circuit configuration for a starter motor for starting an internal combustion engine in a motor vehicle, comprising:
a current limiting device to limit a starting current of the starter motor; and a bridging device for bridging the current limiting device; wherein the bridging device includes a switching relay and a resistor, wherein an internal resistance of the switching relay coil and the resistor form a voltage divider for a voltage dropping across the starter motor, and wherein the bridging device is positively control able by the voltage dropping across the starter motor in such a way that the current limiting device is bridged beginning at a certain rotational speed.
