How to Wire a 4-Way Switch, Electrician Father Teaches His Son how to Wire his 1st, Thoughts?

Watch on YouTube

What happens here

The video begins by establishing the fundamental requirement for any 4-way switch setup: it necessitates the use of two 3-way switches, which act as the start and end points of the lighting circuit. The instructor then visually presents a 4-way switch, highlighting that it has additional terminals compared to a standard 3-way switch, indicating its role as an intermediary in more complex circuits. A wiring diagram illustrates the positions of the power source, two 3-way switches (Location 1 and Location 2), a 4-way switch (Middle), and the light fixture.

Goal: Recognize the roles and placement of 3-way and 4-way switches in a multi-location lighting circuit.

Tools and materials

  • 3-Way Switch — Serving as the beginning and end points for the multi-location lighting circuit
  • 4-Way Switch — Acting as an intermediary switch within a multi-location circuit, between the two 3-way switches
  • 4-Way Switch Wiring Diagram — Visualizing the circuit layout and component connections

You must use two, three-ways. [music] >> What does a four-way look like? >> A four-way looks just like that, but with another terminal. >> Correct. Now, let's think of this as we're going to make a sandwich. [music] Power is coming in on one side of that bun, and the light is coming out on the other side of the bun. What happens if we want to add another patty? We want to add another switch here. Let's assume that we've got a super long hallway.
