    • 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.
    • 与用于气体放电灯的辅助光源一起使用的非电弧电开关包括电流检测部件,定时器功率部件,断开延迟定时器,电压控制部件和相位控制部件。 当从气体放电灯输出的光中断时,或者在气体放电灯的初始预热期间,非电弧电开关激活辅助灯以提供临时照明。 电气开关具有改善的复位可靠性和重复性,同时减少了在气体放电灯的瞬间中断期间所需的复位周期。 此外,电开关不需要负或负电源,以便启动复位并在小于2伏特的电压下工作。
