Abstract:
A switch circuit utilizes an LED for illumination. A diode is connected in parallel with the LED but in opposite orientation, with the LED anode connected to the diode cathode, and the LED cathode connected to the diode anode, to permit discharging of a power supply capacitor of a ballast of a lamp such as a compact fluorescent light (CFL) bulb. Undesirable flickering of the CFL are then avoided.
