Abstract
A starter switch for a fluorescent lamp including a microswitch actuated by an electrically heated bi-metallic expansion element. A second bi-metallic element is provided to compensate for changes in ambient temperature, thus rendering the initial switch adjustments independent of surrounding temperature changes. The elements are selected to provide a desired filament heating delay for the lamp prior to ignition switching, and to recycle after a predetermined time in the event of non-ignition.
