Light Switch Replacement in Milwaukee, WI

Easy job for a handy do-it-yourselfer: Light-Switch Replacement



We get it – even the simplest of electrical problems to the lay man can be confusing and potentially scary to deal with. You may not want to attempt a repair on your own for fear of shocking yourself, or doing it completely wrong and making a small situation worse.

While a light switch replacement is a fairly easy job for the do-it-yourselfers at home, we understand that you may want one of our superheroes to come out and do it for you.

But, if you are feeling bold today or know a handy man that can take care of the job for you, we will provide you with some steps to follow to make for a successful installation.

How to replace a light switch in seven easy steps

  1. Turn off the power at the main circuit breaker.
  2. Unscrew and remove the switch plate, then use a voltage tester to ensure the circuit is dead (don’t want any accidents!)
  3. Unscrew the switch from the electrical box and pull it out with the wires still attached: Look for the black wire (incoming hot wire), a return wire that will be any color but green, and sometimes a grounding wire (green or bare copper). Don’t worry about the other wires you may see in the box.
  4. Look at your old and new switches, and find the corresponding locations for the electrical screw connectors: Because the power is off, you can unscrew and connect one wire at a time to save yourself any confusion.
  5. Attach the the first wire you unscrew to the same-colored screw on the new switch as it was on the old:  In case you don’t know how to connect a wire to the terminal, first strip off about 1/2 inch of insulation using a wire stripper and twist the end into a clockwise loop with pliers. Don’t wrap it more than 3/4 of the way around the terminal screw. Then, hook the wire clockwise around the screw and tighten the screw.
  6. Push the new, wired switch back into the electrical box and screw it in place.
  7. Screw on the switch plate, turn on the power, and test.
