What is a 3-Way Switch?

A 3-way switch is a type of electrical switch that allows you to turn one or more lights on and off from multiple locations. This type of switch is commonly used in homes and offices to control lighting from two or more rooms. They are also used to control multiple lights from a single location, such as a stairway or hallway.

What You Need to Wire a 3-Way Switch for Two Lights

Before you get started, you’ll need to make sure that you have all the necessary materials. You’ll need the following items to complete your project:

  • Three-way switch
  • Wires
  • Wire cutter
  • Wire strippers
  • Screwdriver
  • Electrical tape
  • Two-light fixtures

Step 1: Turn off power

Before you start any wiring project, you must make sure that the power is turned off from the breaker box. This will ensure your safety and prevent any electrical shock or damage. Once you have verified that the power is off, you can proceed to the next step.

Step 2: Connect the Wires

Start by connecting the wires to the 3-way switch. The wires should be connected to the terminals marked “Common”, “Traveler”, and “Ground”. The Common terminal is usually the one labeled “COM”, while the Traveler terminals are usually labeled “T1” and “T2”. Once the wires are connected, you can move on to the next step.

Step 3: Attach Fixtures

Now you’ll need to attach the two light fixtures. Start by connecting the black wire to the black terminal on the light fixtures. Then attach the white wire to the white terminal. Finally, attach the green wire to the ground terminal. Once the fixtures are connected, you can move on to the next step.

Step 4: Install the 3-Way Switch

Now you’re ready to install the 3-way switch. You’ll need to attach the switch to the wall box using the screws provided. Once it’s securely attached, you can connect the wires to the terminals on the switch. Be sure to connect the Common wire to the Common terminal, and the Traveler wires to the Traveler terminals. Finally, connect the green wire to the ground terminal.

Step 5: Test the Wiring

Once you’ve finished the wiring, it’s time to test it. Turn the power back on and make sure that the lights turn on and off correctly when you switch the 3-way switch. If everything works correctly, you’ve successfully wired a 3-way switch for two lights.


Wiring a 3-way switch for two lights is a simple project that can be completed in a few hours. With the right materials and tools, and a little bit of patience, you can successfully complete your wiring project. Once you’ve completed the wiring, you’ll be able to control two light fixtures from two or more locations. Good luck!
