Dimmer switches have become increasingly popular over the years, as they allow for precise control of lighting levels in a room. In the past, dimmer switches were only available as basic on/off switches, but now we have 4 way dimmer switches that make controlling lights even easier. A 4 way dimmer switch can control a single light or multiple lights in a circuit. In this article, we will discuss the wiring diagram for a 4 way dimmer switch.
What is a 4 way dimmer switch?
A 4 way dimmer switch is a complex electrical switch that allows you to control a light from three or more locations. Unlike a 3 way switch that only allows you to control a light from two locations, a 4 way switch provides more options to control a light from multiple locations.
A 4 way switch works by using two 3 way switches and one 4 way switch. The 3 way switches are placed at either end of the circuit, and the 4 way switch is placed in the middle. When you flip any one of these switches, the light will turn on or off, depending on its current state.
How does a 4 way dimmer switch work?
A 4 way dimmer switch works in a similar way to a regular 4 way switch, but it includes a dimmer function. The dimmer function allows you to control the brightness of the light by turning a dial on the switch. This feature is especially useful if you have multiple lights in a room that you want to control separately.
The wiring for a 4 way dimmer switch is slightly more complex than for a regular 4 way switch. However, once you understand the basic principles, it becomes much easier to wire. Below is a diagram of a typical 4 way dimmer switch wiring diagram.

The wiring diagram for a 4 way dimmer switch is shown below:
First, you need to turn off power to the circuit. Then, remove the switch cover and unscrew the switch from its box. Next, connect the wires according to the diagram below:
Wiring instructions
Step 1: Connect the black wire from the power source to the common terminal (black screw) on the 3-way switch.
Step 2: Connect the red and white wires from the power source to the 4-way switch at the top and bottom brass-colored screws.
Step 3: Connect the black and red traveler wires on the 3-way switches to the brass-colored screws on the 4-way switch.
Step 4: Connect the red and black traveler wires from the other 3-way switch to the brass-colored screws on the 4-way switch.
Step 5: Connect the remaining white wire to the silver-colored screw on the 3-way switch, and the green (or bare copper) wire to the green screw on the switch.
After you have connected all the wires, screw the switches back into their boxes and replace the cover. Turn the power back on and test the switches to make sure they are working correctly.
FAQs
1. Can I use a 4 way dimmer switch with LED lights?
Yes, you can use a 4 way dimmer switch with LED lights, but you need to make sure that the switch is compatible with LED lights. Check the manufacturer’s instructions for information on compatibility.
2. Can I use a 4 way dimmer switch in a circuit with other switches?
Yes, you can use a 4 way dimmer switch in a circuit with other switches, but you need to make sure that the wiring is correct. Consult an electrician if you are unsure.
3. How do I troubleshoot a 4 way dimmer switch that is not working?
If your 4 way dimmer switch is not working, first make sure that the power is turned on and that the light bulbs are working properly. Check the wiring to make sure that all the connections are tight and secure. If you are still having problems, consult an electrician.
4. Can I install a 4 way dimmer switch myself?
Installing a 4 way dimmer switch requires some basic electrical knowledge and skills. If you are unsure about how to do it, consult an electrician.
5. Are there any safety precautions I should take when installing a 4 way dimmer switch?
Yes, always turn off the power to the circuit before working on it. Wear protective gear such as gloves and safety glasses, and make sure that the wiring is done correctly to avoid electrical shock or fire.
