Carefully pull out the old switch but leave the wires connected for now. Once you are positive that power has been cut to this particular switch, unscrew the switch plate (most are secured with two small flathead screws), then unscrew the old switch from the wall (here, flat-head and Phillips-head screws are equally common). Sometimes breakers are mislabeled, so double-check before moving on to the next step. To be on the safe side, test the switch to make sure it no longer turns the light on.
That means going to the breaker box and switching off the breaker that controls the switch you intend to replace. Skipping this part or doing it incorrectly could be fatal.īefore you do anything else, ensure that no power is running along the circuit that you’ll be working on. It is vital to complete this first step correctly.
Wire on off switch update#
Tired of your almond-colored toggle light switches, and want to update them with more modern screwless wall plates and rocker switches? This is a simple job for a DIYer, given that you work carefully and follow basic safety protocols. The following steps will help you replace old switches with new ones to update their appearance and function. DIYers should not, however, try running new wiring themselves-that’s a job for an electrician. If you take the right precautions, replacing a light switch is generally safe and low-risk because you’re manipulating wires that have already been professionally installed. When it comes to home wiring, the best rule of thumb is that if you don’t feel comfortable working with electrical wiring, just don’t do it.

The following basic light switch wiring how-to outlines the steps to wiring a light switch, both for single-pole switches and 3-way switches. You just have to disconnect the wires from the existing switch and connect them-in the same manner-to the new switch. The good news is that you don’t need to know advanced circuitry in order to replace a light switch. Still others act as safety mechanisms to reduce the risk of electrical shock. Within the cables are wires designated to do different jobs: Some supply electricity to the switches while others carry the electricity back to the service panel.
All circuits start at the service panel and carry electricity through cables to switches and outlets and then back to the service panel. This panel is comprised of individual breakers that divert electricity to various circuits.
In a residential setting, electrical power comes into the home and is distributed via a service panel.
