4-way switches are a convenient lighting solution that allow you to have control from multiple locations, such as the top and bottom of a stairway, or from both ends of a long hallway. In this article, we will discuss the wiring diagram for a 4 way switch setup with the light in the middle.
What is a 4-Way Switch?
A 4-way switch is a type of switch used in conjunction with two 3-way switches to control a light from multiple locations. Unlike a traditional switch, which has only two states (on or off), a 4-way switch has three states (on, off, or in between). This allows you to control the light from either of the two 3-way switches, regardless of the position of the other 3-way switch.
How Does a 4-Way Switch Work?
A 4-way switch works by interrupting the hot wire that runs between the two 3-way switches. When the switch is in the on position, the hot wire is connected to the common terminal of the switch. When the switch is in the off position, the hot wire is interrupted, cutting power to the light.
When a 4-way switch is in the in-between position, it allows the hot wire to pass through the switch without interruption, allowing the light to be controlled by the other 3-way switch.
Why Use a 4-Way Switch?
4-way switches are a convenient solution for controlling a light from multiple locations, especially in larger rooms or areas with multiple entry points. They allow you to turn the light on or off from any of the two 3-way switches, no matter which switch was used to turn the light on or off initially.

As with any electrical wiring, it is important to turn off the power at the breaker box before starting any work on the wiring. Additionally, it is important to have a good understanding of basic electrical concepts and to follow all safety guidelines when working with electricity.
Step-by-Step Instructions for Wiring a 4-Way Switch with the Light in the Middle
Step 1: Gather Your Tools and Materials
Before beginning any electrical work, make sure you have all necessary tools and materials, including:
- Wire stripper
- Needle nose pliers
- Electrical tape
- 4-way switch
- 2 3-way switches
- 14/3 electrical wire
- Wire connectors
Step 2: Turn Off the Power
Make sure the power is turned off at the breaker box before starting any electrical work. This will help prevent injury or damage to equipment.
Step 3: Connect the 3-Way Switches
Begin by connecting the two 3-way switches using 14/3 electrical wire. The black wire should be connected to the common terminal on each switch, while the red and white wires should be connected to the traveler terminals.
Step 4: Connect the 4-Way Switch
Next, connect the 4-way switch using 14/3 electrical wire. The black and red wires should be connected to the two traveler terminals on the switch, while the white wire should be capped off with a wire connector.
Step 5: Connect the Light Fixture
Finally, connect the light fixture using 14/2 electrical wire. The black wire should be connected to the hot wire coming from the 3-way switch, while the white wire should be connected to the neutral wire. The ground wire should be connected to the ground wire from the power source.
FAQ
Can I Use a 4-Way Switch with More Than Two 3-Way Switches?
Yes, you can use a 4-way switch with more than two 3-way switches to control a light from multiple locations. However, the wiring diagram will vary depending on the number and location of the switches.
What is the Difference Between a 3-Way Switch and a 4-Way Switch?
A 3-way switch is a switch that allows you to control a light from two locations. A 4-way switch is used in conjunction with two 3-way switches to control a light from three or more locations.
Can I Use a 4-Way Switch with a Dimmer Switch?
Yes, you can use a 4-way switch with a dimmer switch to control a light from multiple locations. However, you will need to make sure that the dimmer switch is compatible with the type of light bulb you are using.
What is the Best Way to Troubleshoot a 4-Way Switch?
If you are experiencing problems with your 4-way switch setup, the best way to troubleshoot the problem is to start by checking the wiring connections. Make sure all wires are properly connected and that there are no loose connections or wires touching each other. Additionally, you may want to check the bulbs and switches to make sure they are functioning properly.
Do I Need to Hire an Electrician to Install a 4-Way Switch?
If you have experience working with electrical wiring and have a good understanding of basic electrical concepts, you may be able to install a 4-way switch yourself. However, if you are unsure about any aspect of the installation process, it is always best to hire a professional electrician to ensure that the job is done safely and correctly.
