Through repeated use, pull chains used as switches on light fixtures inevitably break, leaving the light in either the "on" or "off" position. Rather than attempting to fix the pull chain itself, it is actually easier to replace the entire unit. As with any home wiring project involving electricity, safety is the most important factor. Take extra precautions to be sure the power is off to the light fixture before replacing the switch.
