By reading this article, you’ll not only gain practical knowledge but also understand the benefits of each approach, equipping you to make an informed decision​​.

When You Don’t Need an Electrician

Replacing a light switch is a relatively simple task that most people can do themselves. Here are the steps involved in replacing a light switch:

  1. Turn off the power: Before you start, turn off the power to the light switch at the main circuit breaker box. It’s a good idea to mark the breaker switch with tape to ensure no one else turns it back on while you’re working. Confirm that you’ve turned off power to the correct light switch at the breaker box by flipping the wall switch you’re changing on and off.
  2. Remove the wall plate: Remove the face-plate from the light switch by unscrewing the screws with a screwdriver until the plate comes away freely. Flip the light switch on and off to ensure no electricity is flowing through the switch.
  3. Determine voltage absence: Use a voltage tester to test if there is voltage at the contacts. Do not work on live circuits if you are not an experienced professional.
  4. Unscrew the light switch: Remove the light switch from the housing by unscrewing the screws at the top and bottom of the switch, using a screwdriver. Gently pull the light switch out of the housing.
  5. Compare the switches: Pull the old switch out from the box far enough that its connections can be clearly seen. Confirm that the new switch has all the same contacts (screws) as the old switch, with matching colors.
  6. Disconnect the switch: Take note of the existing wiring since the new switch will need to be wired in exactly the same configuration. Unscrew the screws on both sides of the the light switch until the wires may be unhooked. If necessary, these screws may be fully removed to prevent the straightening of the wire loops.
  7. Install the new switch: Unhook the wires from the screws. Begin connecting the wires to the new switch according to the wiring configuration of the original switch. Push the switch into the housing and begin reassembling.

Here is a list of tools and materials needed to replace a light switch:

  1. Screwdriver
  2. Electrical Tester/Voltage Detector
  3. Safety Glasses
  4. Utility Knife (Optional)
  5. Light Switch
  6. Wire Connectors (Optional)

To ensure safety while replacing a light switch, follow these tips:

  1. Always turn off the power before working on a light switch.
  2. Use a voltage tester to check for live wires before working on a light switch.
  3. Hire a qualified electrician to install or repair light switches if you have any doubts or questions about the connections or if your home’s wiring doesn’t appear compatible with the changes you’re making.

When You Might Need an Electrician

When it comes to replacing a light switch, there are some situations where it might be best to hire an electrician. For instance, if the wiring is complex or if you are replacing a switch in an older home, it is best to call in a professional.

Hiring an electrician has several benefits. First and foremost, it ensures that the work is done safely and correctly. Electricians have the necessary training and experience to handle electrical work, which can be dangerous if not done properly. They also have access to the latest equipment and tools, which can help them complete the job more efficiently.

According to a source, if the light switch has been showing signs of catching fire, then an electrician will need to be called. A sign of this would be black marks on the switch or around the area. Another time an electrician would need to be called is if the breaker keeps flipping or the switch is not working after replacement.

In addition, hiring an electrician can save you money in the long run. If you attempt to replace a light switch yourself and make a mistake, it could end up costing you more to fix the problem than it would have to hire an electrician in the first place.
