When it comes to wiring a 4 way switch with dimmer, it can be a bit confusing. However, with the right instructions and diagram, you can easily install and wire the switch without any difficulty. In this article, we will guide you through the process and provide you with a detailed wiring diagram for your convenience.
What is a 4 Way Switch?
A 4 way switch is a type of switch that is used to control a light or a set of lights from multiple locations. They are commonly used in stairways, hallways, or large rooms where it is necessary to control the lighting from more than two locations. A 4 way switch has four terminals or poles, and it allows you to turn the light on or off from any of the four locations.
How Does a 4 Way Switch Work?
Unlike a standard switch, a 4 way switch does not have an on/off position. Instead, it has two positions that allow the electricity to flow through the circuit in either direction. This means that when one switch is in the up position, the other switch can be in the up or down position, and this will not affect the flow of electricity.
To turn the light on, you will need to have at least one switch in the up position, and to turn the light off, all switches must be in the down position. This means that you can turn the light on or off from any of the four locations.
What is a Dimmer Switch?
A dimmer switch is a type of switch that allows you to adjust the brightness of the light. They are commonly used in living rooms, dining rooms, and bedrooms to create a cozy and comfortable atmosphere. A dimmer switch has a knob or a slider that allows you to adjust the brightness of the light according to your preference.
How Does a Dimmer Switch Work?
A dimmer switch works by adjusting the voltage that is supplied to the light. When you turn the knob or the slider to the right, the voltage is increased, and the light becomes brighter. When you turn the knob or the slider to the left, the voltage is decreased, and the light becomes dimmer.
How to Wire a 4 Way Switch with Dimmer?
Now that you understand what a 4 way switch and a dimmer switch are, let’s take a look at how to wire them together.
Step 1: Turn off the power to the circuit at the breaker box.
Step 2: Remove the existing switch or switches that control the light.
Step 3: Identify the common terminal on each switch. It is usually labeled with a black screw or a brass-colored screw.
Step 4: Connect the common terminal of the first switch to the power source. This is usually the black or red wire.
Step 5: Connect the common terminal of the second switch to the light fixture. This is usually the black or red wire.
Step 6: Connect the travelers of the first switch to the travelers of the second switch using a 3-wire cable.
Step 7: Connect the common terminal of the third switch to the travelers that are coming from the first switch.
Step 8: Connect the common terminal of the fourth switch to the travelers that are coming from the second switch.
Step 9: Connect the travelers of the third switch to the travelers of the fourth switch using a 3-wire cable.
Step 10: Connect the common terminal of the dimmer switch to the common terminal of the third switch.
Step 11: Connect the travelers of the dimmer switch to the travelers of the fourth switch.
Step 12: Install the switches back into the boxes and turn on the power.

FAQ
What is the difference between a 3 way switch and a 4 way switch?
A 3 way switch is a switch that is used to control a light or set of lights from two locations, while a 4 way switch is used to control a light or set of lights from three or more locations.
How do I know which wire is the common wire?
The common wire is usually the black or red wire, and it is connected to the common terminal of the switch. It is usually labeled with a black screw or a brass-colored screw.
Can I use a dimmer switch with any type of light bulb?
No, not all light bulbs are compatible with dimmer switches. You need to use a dimmable light bulb that is compatible with your dimmer switch. Check the packaging or consult with the manufacturer to ensure compatibility.
Is it difficult to install a 4 way switch with dimmer?
No, it is not difficult to install a 4 way switch with dimmer as long as you follow the instructions carefully and have some basic knowledge of electrical wiring. However, if you are not comfortable working with electricity, it is best to hire a professional electrician to do the job for you.
Do I need any special tools to install a 4 way switch with dimmer?
You will need a few basic tools such as a screwdriver, pliers, wire stripper, and wire nuts to install a 4 way switch with dimmer. You may also need a voltage tester to ensure that the power is off before you begin working on the switch.
