If you are planning to install a 4-way switch wiring diagram for multiple lights, then you’ve landed in the right place. This article provides an in-depth guide on wiring a 4-way switch with multiple lights, step by step. Four-way switches give you the ability to control a single light or a set of lights from three or more locations.
What are 4-Way Switches?
Four-way switches are electrical switches used to control one or more lights from three or more locations. They are wired together in a circuit and work in conjunction with two-way switches to control lights from more than two locations. A four-way switch has four terminals or poles, with two pairs of traveler wires connected to them.
The wiring of 4-way switches can be complicated, but this article will explain it in a simple and easy-to-understand way. Below we’ve provided examples of 4-way switch wiring diagrams for multiple lights.
Wiring Diagram for 4-Way Switch with Multiple Lights

The above diagram shows a sample 4-way switch wiring diagram with multiple lights. In this setup, the power source comes in through the first switch, travels through the wires to the second switch, and then to the third switch. From there, wires run to a set of lights.
Each switch controls the power flow to the lights, so when one is off, the others still function. If any switch is turned off, the power is cut off from the lights, and they turn off.
Four-Way Switch Wiring Instructions
Step 1: Turn Off the Power
Before you begin wiring, you must turn off the power to the circuit that you will be working on. This will ensure that you do not get electrocuted, injured, or damage any of the wiring in the circuit.
You can turn off the power at the circuit breaker or fuse box, or you can simply turn off the light switch that controls the circuit you will be working on. Once you have turned off the power, use a voltage tester to verify that the power is off at the circuit.
Step 2: Install the First 3-Way Switch
The first switch in a 4-way switch wiring diagram is a three-way switch. This switch has three terminal screws, including one common screw and two traveler screws. The common screw is usually black, and the traveler screws are usually brass or silver-colored.
To install the first 3-way switch:
- Remove the cover plate and screws from the electrical box and pull out the switch.
- Attach the black wire from the power source to the common screw on the switch. This is usually the darker colored screw.
- Attach the white neutral wire to the silver-colored screw on the switch.
- Attach the two traveler wires to the two brass-colored screws on the switch.
- Screw the switch back into the electrical box and reattach the cover plate.
Step 3: Install the Second 3-Way Switch
The second switch in the circuit is also a three-way switch, and it is wired in a similar way to the first switch. To install the second 3-way switch:
- Remove the cover plate and screws from the electrical box and pull out the switch.
- Attach the black wire to the common screw on the switch.
- Attach the two traveler wires to the two brass-colored screws on the switch.
- Screw the switch back into the electrical box and reattach the cover plate.
Step 4: Install the First Four-Way Switch
The first four-way switch is wired differently than the three-way switches. It has four terminal screws, with two pairs of traveler wires attached to them. To install the first four-way switch:
- Remove the cover plate and screws from the electrical box and pull out the switch.
- Attach one pair of traveler wires to one set of screws on the switch.
- Attach the other pair of traveler wires to the other set of screws on the switch.
- Screw the switch back into the electrical box and reattach the cover plate.
Step 5: Install the Second Four-Way Switch
The second four-way switch is wired in the same way as the first one. To install the second four-way switch:
- Remove the cover plate and screws from the electrical box and pull out the switch.
- Attach one pair of traveler wires to one set of screws on the switch.
- Attach the other pair of traveler wires to the other set of screws on the switch.
- Screw the switch back into the electrical box and reattach the cover plate.
Step 6: Install the Final 3-Way Switch
The final switch in the circuit is a three-way switch, and it is wired in the same way as the first and second switches. To install the final 3-way switch:
- Remove the cover plate and screws from the electrical box and pull out the switch.
- Attach the black wire from the lights to the common screw on the switch.
- Attach the white neutral wire to the silver-colored screw on the switch.
- Attach the two traveler wires to the two brass-colored screws on the switch.
- Screw the switch back into the electrical box and reattach the cover plate.
FAQs
What is a 4-way switch?
A 4-way switch is an electrical switch used to control one or more lights from three or more locations. It is wired together in a circuit and works in conjunction with two-way switches to control lights from more than two locations.
How many lights can a 4-way switch control?
A 4-way switch can control multiple lights as long as they are wired in parallel. In a parallel circuit, each light is connected to the power supply independently, so turning off one light does not affect the others.
How do I wire a 4-way switch with multiple lights?
To wire a 4-way switch with multiple lights, you will need to install two 3-way switches and two 4-way switches in the circuit. The 3-way switches control the power flow to the 4-way switches, which in turn control the lights. Refer to the wiring diagram and follow the steps outlined in this article to wire the switches correctly.
Can I use a 4-way switch to control a ceiling fan?
A 4-way switch is not typically used to control a ceiling fan. Ceiling fans usually require a different type of switch with a speed control function. However, if you want to control a ceiling fan from multiple locations, you can use a combination of 3-way switches and a 4-way switch to wire the circuit.
Can I wire a 4-way switch myself?
Wiring a 4-way switch can be complicated, and it is best to hire a licensed electrician to do the job. However, if you are comfortable working with electricity and have some electrical knowledge, you can wire a 4-way switch yourself. Just make sure to turn off the power to the circuit before you begin, and follow the wiring diagram and instructions carefully.
Conclusion
Installing a 4-way switch wiring diagram for multiple lights is a bit challenging, but with this article’s help, you can do it without any problem. Following the steps outlined here will help you install the switches correctly and safely. Remember to turn off the power to the circuit before doing any wiring and to double-check your work before turning the power back on.
