  • Low current solution for illuminated switches using DC operated LEDs
    Patent number: 8853963
    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.
    Type: Grant
    Filed: August 30, 2012
    Date of Patent: October 7, 2014
    Assignee: Hubbell Incorporated
    Inventors: Stephen M. Liscinsky, Gregg R. Schelmetic
