ABSTRACT:
A rapid start fluorescent lamp ballast with a secondary winding supplying lamp current and tertiary windings for supplying heater current, has a magnetic switch which senses current through the secondary winding and opens the heater current circuit after the lamp starts and draws operating current from the secondary winding. The current sensing magnetic switches shown are a slow acting relay with its coil in the secondary circuit and a magnetic reed switch physically disposed in the magnetic field of the secondary ballast winding.
