The invention relates to a circuit assembly for a motor vehicle. The circuit assembly comprises an electric motor. The electric motor comprises a control unit, wherein the control unit is designed to actuate the electric motor, in particular a stator of the electric motor, for rotating the rotor. According to the invention, the circuit assembly comprises a controllable switch with a control connection. The controllable switch is connected, in particular in a separable manner, on the input side to a battery potential of an on-board power supply system of the motor vehicle. The controllable switch is connected on the output side to the electric load, in particular the electric motor, preferably to the control unit of the electric motor.; The control unit has a control input for receiving an activation signal for activating the load, in particular in the case of an electric motor for rotating a rotor of the electric motor. The control unit is connected to the control connection of the controllable switch and des
