Are you tired of walking up and down the stairs to turn off the lights? Do you want to control your lighting from different locations in your home? If so, installing a three-way switch may be the solution you’ve been looking for. In this article, we’ll walk you through the process of wiring a three-way switch where the power is at the switch.
First, let’s define what a three-way switch is. A three-way switch allows you to control a single fixture or set of fixtures from two different locations. This is achieved by having two switches that are wired together, allowing you to turn the lights on or off from either location.
Before getting started, it’s important to turn off the power at the circuit breaker. Once you’ve done that, you can begin wiring the switches. The first step is to identify which wires are which. You should have three wires: a black “hot” wire, a white neutral wire, and a bare copper ground wire.
The black wire is the “hot” wire that carries the electricity. It should be connected to the common terminal on one of the switches. The white wire is the neutral wire and should be connected to the silver screw on each switch. The bare copper wire is the ground wire and should be connected to the green screw on each switch.
Next, you’ll need to connect the traveler wires. These are the wires that allow the switches to communicate with each other. You should have two traveler wires, which can be any color other than black, white, or green. These wires should be connected to the brass screws on each switch.
Once you’ve connected all the wires, you can turn the power back on and test your switches. If everything is wired correctly, you should be able to turn the lights on or off from either location.
It’s important to note that if you’re not comfortable working with electricity, you should hire a licensed electrician to do the installation for you. Working with electricity can be dangerous, and it’s always better to be safe than sorry.
In conclusion, wiring a three-way switch where the power is at the switch is a relatively simple process. By following the steps outlined in this article, you can have your switches up and running in no time. Just remember to turn off the power before getting started, and if you’re not comfortable working with electricity, don’t hesitate to call a professional.

The Basics of Three-Way Switches
A three-way switch has three terminals: one common and two traveler terminals. The common terminal is usually the black screw, while the traveler terminals are either brass or silver. When the switch is in the up position, the common terminal is connected to one traveler terminal, and when the switch is in the down position, the common terminal is connected to the other traveler terminal.
Power at the Switch
The three-way switch wiring diagram with power at the switch means that the power supply comes into the switch box first. The following steps will guide you on how to wire a three-way switch with power at the switch:
Step 1: Turn Off Power Supply
Before doing any electrical work, always turn off the power supply to the circuit you will be working on. This can be done by flipping the circuit breaker or removing the fuse from the panel.
Step 2: Remove Existing Switch
If there is an existing switch, remove it from the switch box by unscrewing the mounting screws and pulling it out. Be careful not to touch any wires inside the box.
Step 3: Install New Switch
Install the new three-way switch in the box by attaching it to the mounting screws. Make sure the common terminal is on the bottom and the traveler terminals are on top.
Step 4: Connect Ground Wires
Connect the ground wire from the switch to the ground wire in the box. This is usually a bare copper wire or a green wire.
Step 5: Connect Neutral Wires
Connect the white neutral wire from the power supply to the white neutral wire in the box. The neutral wire is usually marked with a black or red stripe.
Step 6: Connect Hot Wire to Common Terminal
Connect the black hot wire from the power supply to the common terminal on the switch. This is usually the black screw.
Step 7: Connect Traveler Wires
Connect one traveler wire to each of the remaining terminals on the switch. It doesn't matter which traveler wire goes where.
Step 8: Replace Switch Cover
Replace the switch cover and turn the power supply back on. Test the switch to make sure it is working properly.
The Bottom Line
