Four Way Dimmer Switch Wiring Diagram

By | March 3, 2022



Four-way dimmer switches are an incredibly useful addition to any lighting system and provide a great way to serve both your practical and aesthetic needs. A four-way dimmer switch wiring diagram explains how to wire the switches so that you can adjust the lighting in your home from multiple locations.

These dimmer switches are especially useful when there is more than one switch controlling a single light fixture. For example, if you have a hallway light controlled by a switch at both ends, the four-way switch wiring will allow you to dim the light from either end. This is especially convenient for late night tasks such as reading since you don’t need to traverse the whole hallway to adjust the lighting.

The wiring diagrams required are simple, even for those unfamiliar with basic electrical wiring. In the most basic setup, two three-way switches are wired between a power source and the light fixture. Each switch has three terminals: a common terminal, a pair of traveler terminals, and an on/off terminal. The four-way switch is connected between the two three-way switches, with the two traveler terminals of the four-way switches linked together. This configuration allows the light level to be adjusted from either of the two switches.

Perhaps best of all, you don’t need to be an electrical expert to install a four-way switch. With just a few tools and some basic knowledge of wiring, you can easily install a new four-way dimmer switch in your home and start enjoying greater control over your lighting.

Using a four-way dimmer switch wiring diagram, you can easily and safely bring the convenience of adjustable lighting into your home. Get started today and experience the difference a few switches can make in your lighting environment!
