Replace a Light Switch - Great Lakes Ace Hardware Store

There are 3 important steps to replace a light switch:

  1. Make sure the power is turned off to the circuit on which you are working. Use a voltage meter or non-contact voltage tester to verify there is no power to the switch or outlet.
  2. Unscrew old light switch from electrical cover and remove wires one at a time and mark to insure proper placement on new switch. A single pole switch controls one light from one switch. A three- way switch controls one light from two switches, for example the top and bottom of a flight of stairs.
  3. Insert wires in back or switch or wrap clockwise around the correct screws. When wires have been connected to new switch wrap contacts with electrical tape if using screws.
