A circuit arrangement, which includes a switched-mode power supply energized by a source and which is controlled by a control circuit. The switched-mode power supply supplies the control circuit with energy during operation. The circuit also comprising a starter circuit for applying a supply current to the control circuit when the arrangement is put into operation. A particularly simple and inexpensive construction is obtained in that the starter circuit comprises a capacitive voltage divider which is fed directly by the source and is provided with a tapping wherefrom the supply current is derived via a rectifier element.
