How to Wire a Light Controlled by Two Switches



One of the most common wiring projects in a home is wiring a light controlled by two switches. Being able to control a light from two switches allows for more convenience and flexibility in how the light is used. In this article, we'll show you how to wire a light switch so that it is controlled by two switches and discuss the pros and cons of this setup.

Installing lights is an easy DIY project and usually just requires basic tools. However, the wiring and installation may differ based on local laws and regulations. Make sure to check and understand those before you start. Afterward, the setup is simple and straightforward.

Getting Started



Before you start wiring a light controlled by two switches, first you will need to gather the necessary supplies. Depending on the type of switches you have, you may need additional materials as well. These generally include:


  • wall switches

  • light fixture

  • electrical box

  • wire cutters

  • stimulator

  • electrical tape

  • wire nuts



Once you have all your supplies, you can go ahead and begin the wiring process. Before you do, you should also review a wiring diagram for a light controlled by two switches. This will help you to better understand how the wiring should be done.

Connecting the Wires



Begin by connecting the wires that will go to the switches. For this connection, use two wires, one of them going from the box to the switch, and the other from the switch to the light. Cut the wires in such a way that each one has enough length to reach its destination. Then, using the wire nuts, twist the cables together with the switches securely. Finally, secure the connections with electrical tape.

Next, connect the remaining wires to the switches and to the light fixture. First you will need to identify the terminals on the switches. On most types of switches, they will be labeled “common” and “traveler.” Once you have identified the terminals, connect the wire to the traveler terminal on each of the two switches, and then the wire to the common terminal. Also connect the remaining two wires to the light fixture.

Final Steps



At this point, you should run a test to make sure the wiring is correct. Again, refer to the wiring diagram to understand how to do this. If everything looks correct, then you are ready to install the switches and the light fixture.
Install the switches in the wall boxes, making sure to securely close the covers. Then, screw the light fixture in place. Finally, plug in the lamps and turn on the power.

Conclusion



Wiring a light controlled by two switches is a simple task that can add convenience and make your home much more functional. Once everything is wired and installed, you can rest assured that you have done it properly and that the lights will turn on and off without any issues. By following the steps applied above, you can wire your next home project successfully.
