How to Add a Wall Switch to a Ceiling Fixture

Turn Off Power

  • Turn off power at the circuit breaker panel box. Use a voltage tester to ensure power is off at the outlet. 
  • Plan a cable path that crosses as few studs or joists as possible. You may have to cut an access hole to run cable through framing with a fish tape.

Run Cable to the Switch Box

If your project requires cutting drywall, use a pencil to mark the location of the hole (check for studs with a stud finder) and score the paper surface with a utility knife. Cut along the inside of the knife cut with a drywall saw. The resulting hole will be free of ragged edges. You can also cut drywall with a spiral cutting tool or a saber saw.

Add nailing plates wherever you bore holes in the framing. Cut a hole for a remodel switch box and pull cable through. Strip the wires as needed.

Connect the Ground Wire

  • Ground the fixture by connecting it to a grounding wire. 
  • This wire should lead to a neutral bar in the service panel. From the service panel, heavy-gauge copper grounding wire should run to one or a combination of the following: Cold water pipe, grounding rods driven at least 10 feet in the ground or a metal plate sink in a footing.

Remove the black wire from the fixture lead, splice it to the new white wire to the switch and mark it black. Splice the new black wire to the fixture’s black lead.

Attach both wires to terminals and mark the white wire black. Restore power to the circuit and test. If necessary, repair the access hole in drywall.
