3 Way Switch Explained – How to Wire (2) 3-Way Electrical Switches to Control a Single Light Fixture




This video provides a practical understanding of how a single pole double throw switch (3-way switch) works. I also provide instructions on how to wire three-way switches. When wired correctly, (2) 3-way switches can be used to control a single light fixture, outlet, or ceiling fan. By toggling power over the transport wires, current can be provided in both switch positions on a single pole double throw switch (3 way switch). I’ll be adding a 4way electrical switch to this circuit in the coming weeks. Adding a double pole, double throw switch to this circuit will allow the ability to control a single light fixture with 3 switches.
