Q&A for How to Add a Wall Switch to Light Fixture Controlled by a Chain

You will have to replace the existing fixture with one that includes a pull cord.

The new outlet may be in a different configuration from the old one. New outlets have a left side that has a wider slot than the right side. The wider (left) slot is the neutral (white), while the narrower (right) side is the hot wire (black). Generally the hot side has a brass screw and the neutral side has a silver screw. You'll need to reverse the wires on the back of the outlet.

Will it turn on if you remove and/or replace the new bulbs? If so, you just have a defective bulb. If not, there may be a short somewhere in the circuit. To diagnose this, remove the light switch and ensure all the connections are tight and not touching other wires or the electrical box. If the switch is okay, check the light fixture that all the wiring is attached securely and not touching other wires.

Not if you don't mind manually turning the light on and off directly at the fixture. Most people find it easier and more convenient if they can switch on a ceiling light fixture from a wall switch, especially at night.

Are you sure it is looped to an outlet, not another light fixture? Most homes are wired with the wall outlets on separate circuits from lighting. If this is the case, you can't add a switch without switching the outlet as well.

Turn off the light with the chain. Now you can turn the light on or off with the wall switch.
