Abstract
Apparatus for starting and operating a discharge lamp includes a starter device having a normally-closed (N/C) switch including a pair of contacts each connected to a bimetal with the bimetals having opposite flexure deviations. Circuitry is provided for coupling one bimetal to a ballast and also to a discharge lamp whereby short-circuit current flows through both bimetals to open the switch and initiate conductivity of a discharge lamp and through one bimetal to maintain the switch operational and continue lamp conductivity.
