When it comes to controlling the lighting in a room from multiple locations, a 4-way switch is often used. This type of switch allows you to turn the lights on or off from three or more locations, giving you flexibility and convenience in your home. Understanding the wiring diagram of a 4-way switch is essential for proper installation and operation.
Before diving into the wiring diagram, it is important to understand the basic concept of a 4-way switch. Unlike a traditional single-pole switch, a 4-way switch has four terminals instead of two. This allows for multiple switches to control the same set of lights, creating a more versatile lighting setup.

Wiring Diagram Of A 4 Way Switch
The wiring diagram of a 4-way switch consists of two 3-way switches and one 4-way switch to control a light fixture from three or more locations. The key to understanding the diagram is to identify the common terminal on each switch, which is typically labeled as “COM.” The travelers are the other two terminals on the switch, which are used to connect to the other switches in the circuit.
To wire a 4-way switch, you will need to connect the common terminal of the first 3-way switch to the common terminal of the 4-way switch using a black wire. The travelers from the first 3-way switch should be connected to the travelers of the 4-way switch using two red wires. Finally, the common terminal of the second 3-way switch should be connected to the common terminal of the 4-way switch using a black wire, and the travelers from the second 3-way switch should be connected to the remaining terminals on the 4-way switch using two red wires.
It is important to follow the wiring diagram carefully and double-check all connections to ensure a safe and functioning 4-way switch setup. If you are unsure about your wiring abilities, it is always best to consult a professional electrician for assistance.
Overall, understanding the wiring diagram of a 4-way switch is crucial for creating a versatile and convenient lighting control system in your home. By following the correct wiring procedures and consulting with a professional if needed, you can ensure a safe and efficient installation of a 4-way switch.
