Abstract
A magnetic transformer switch which switches its primary flux path upon conduction in its secondary and the combination thereof with a fluorescent lamp in which the heater current is reduced upon lamp ignition by reason of the current in the heater winding in the secondary being reduced upon the primary flux path being switched. A unique construction minimizes both electromagnetic interference and induction losses.
