ABSTRACT:
A circuit including a switching regulator and a pair of pulse transformers for selectively starting and operating a pair of arc discharge lamps. The lamps are arranged to be connected in parallel across the regulator output, and in order to operate one lamp at a time, the circuit is provided with low-voltage switching means for selecting the lamp to be started and operated. This switching means, in the form of a ganged switch, includes a switch portion for completing an enable circuit from the regulator controller for enabling the regulator and a pulse generator, and a second switch portion for steering pulses from the generator to the pulse transformer associated with the lamp selected for operation.
