Safety Suggestions and Tips
Turn off power
Do not nick wires with knife
Make sure wire nut completely covers wires
Level of difficulty
Unscrew cover plate
Cut the power to the light that the switch you are replacing controls. This
is normally done at the "breaker box." Turn the light on and then throw the
breaker that controls the light. The light should go off. If not, throw other
breakers until it does. Remove the face plate from the switch. The plate
is normally held on with two small screws.
Remove old switch
Next remove the switch from the box. Carefully remove the screws at the top
and bottom. Pull the switch from the box by holding the top and bottom of the
switch. When the switch is clear of the box, test the wires for current.
Twist wires together
Remove the wires from the old switch and twist them
onto the existing wires (Dimmer switches almost always have wires coming
Secure wire nuts firmly
You will need two small wire nuts to finish
attaching the existing wires to the switch. Make sure that there is no
exposed wire below the wire nut. Fold the wires down and gently push the switch
back into the box. Screw the switch into place and turn the breaker back on.
Test the switch and replace the faceplate.
