Are you planning to install an illuminated switch for your home lighting system? Do you want to know how to wire a 3-way illuminated switch properly? In this article, we will guide you step-by-step on how to install a 3-way illuminated switch with a wiring diagram, tables, and FAQs. This guide is suitable for DIY enthusiasts and professional electricians alike.
What is a 3-Way Illuminated Switch?
A 3-way illuminated switch is a type of switch commonly used in residential electrical wiring. It allows you to turn on or off a light fixture from two different locations – such as a hallway or staircase. This switch has an illuminated toggle that glows in the dark, making it easy to find in low light conditions.
Before you start wiring a 3-way illuminated switch, you need to gather the necessary tools and materials:
| Tools | Materials |
|---|---|
| – Wire stripper | – 3-way illuminated switch |
| – Screwdriver | – Electrical tape |
| – Voltage tester | – Wire nuts |
| – Pliers | – Electrical wire |
Wiring a 3-Way Illuminated Switch
Step 1: Turn off the power supply to the circuit you are working on by switching off the breaker in the main electrical panel. Test the circuit with a voltage tester to ensure that there is no power flowing to the switch.
Step 2: Remove the cover plate of the existing switch box and unscrew the switch from the electrical box. Gently pull the switch out of the box and loosen the screws holding the wires in place.
Step 3: Identify the wires connected to the old switch – typically, there will be three wires – a black (hot), a white (neutral), and a red or black (traveler). Use a wire stripper to strip off the insulation from the ends of the wires.
Step 4: Connect the wires to the new 3-way illuminated switch. Follow the wiring diagram provided with the switch – typically, there will be four terminal screws – two brass screws (line and load), one black screw (common), and one green screw (ground).
Step 5: Connect the black (hot) wire to the common screw on the new switch. Connect the white (neutral) wire to the green screw. Connect the red or black (traveler) wire to the remaining brass screw.

FAQs
1. What is the purpose of the illuminated toggle on a 3-way switch?
The illuminated toggle on a 3-way switch allows you to locate the switch in low light conditions. It also serves as a visual indication of whether the light is on or off.
2. How do I know which wire is the hot wire?
The hot wire is typically black, but it can also be red or another color. You can use a voltage tester to confirm which wire is hot – it should read 120 volts.
3. Can I wire a 3-way switch with more than one light fixture?
Yes, you can wire a 3-way switch with multiple light fixtures. You will need to use a 4-way switch in conjunction with two 3-way switches to control the lights from three or more locations.
4. What is the difference between a 2-way and 3-way switch?
A 2-way switch allows you to control a light fixture from one location, while a 3-way switch allows you to control the same fixture from two different locations.
5. Do I need an electrician to install a 3-way illuminated switch?
No, you can install a 3-way illuminated switch yourself if you have basic electrical knowledge and the right tools. However, if you are unsure about any aspect of the installation process, it is always best to consult a licensed electrician.
Conclusion
Wiring a 3-way illuminated switch is a simple yet important task that can enhance the functionality and aesthetics of your home lighting system. By following the steps outlined in this guide, you can install a 3-way illuminated switch safely and efficiently.
