Are you planning to install a three way switch in your house? It might seem daunting, but it’s actually a simple task if you have the correct wiring diagram. Not only will you be able to control the same light from two different locations, but you’ll also reduce the number of wires you need to run. In this article, we’ll provide you with an easy-to-follow wiring diagram for a three way switch so that you can do it yourself!
What is a Three Way Switch?
Before we dive into the wiring diagram, let’s first understand what a three way switch is. A three way switch is a type of switch that controls a light fixture from two different locations. This is useful for large rooms, hallways, or staircases where you need to turn on/off the light from both ends.
A three way switch has three terminals – one common terminal and two traveler terminals. The common terminal is usually black, while the traveler terminals are usually brass or copper-colored.
What You’ll Need
Before starting the installation process, make sure you have the following tools and materials:
| Tools | Materials |
|---|---|
| screwdriver | three way switch |
| wire stripper | electrical tape |
| needle-nose pliers | wire connectors |
| flashlight | 14/3 electrical wire |
Step-by-Step Wiring Diagram
Step 1: Turn Off the Power
Before you start any electrical work, it’s important to turn off the power at the breaker box. Use a voltage tester to ensure that the power is off.
Step 2: Remove the Old Switch
After turning off the power, remove the old switch from the wall. You’ll need to remove the cover plate and the screws that hold the switch in place.
Step 3: Connect the Wires
Connect the black wire from the electrical panel to the common terminal of the three way switch. The black wire from the light fixture goes to one of the traveler terminals, and the red wire from the light fixture goes to the other traveler terminal. Use wire connectors to secure the wires. If you have a ground wire, connect it to the green screw on the switch.
Step 4: Install the Switches
Once you’ve connected the wires, install the switches in the wall. Make sure you align them properly and tighten the screws. Install the cover plate.
Step 5: Test the Switches
After installation, turn the power back on and test the switches. You should be able to control the light from both locations.
