I have someone who installed a ceiling fan with light and I told them how to hook it up but they want to work the light from the switch and have the ceiling fan going when the switch is off. I told them they would need 2 switches instead of one which powers the fan and light and can only be controlled by pulling the chains to turn them off or on.
How can they replace the single switch to a double switch-one to control the fan and on for the light?
