Mark Donovan, of HomeAdditionPlus.com walks you through the
process of replacing your own pull chain light switch lampholder in this
video.
Pull strings on pull chain light switch lampholders inevitably
break, even when you treat them with care. When the inevitable occurs, it is
easier and cheaper to replace the entire pull chain light switch lampholder
than it is to attempt to fix the pull string itself.
Warning: When working with electricity use extreme
caution to avoid the risk of electrical shock. Make sure you confirm all
power to the light switch lampholder is off prior to replacing it.
