Abstract:
A non-arcing electrical switch for use with an auxiliary light source for a gaseous discharge lamp includes a current sensing component, a timer power component, an off-delay timer, a voltage control component, and a phase control component. When the light output from the gaseous discharge lamp is interrupted, or during the initial warm up of the gaseous discharge lamp, the non-arcing electrical switch activates an auxiliary lamp to supply temporary illumination. The electrical switch has improved reset reliability and repeatability while decreasing the reset period required during momentary interruptions of the gaseous discharge lamp. Furthermore, the electrical switch requires no negative or minus power supply in order to initiate reset and operates at voltages of less than two volts.
