The Perfect Guide to Three Way Toggle Switch Wiring Diagrams



Toggle switches are a widely used type of electrical switch and can be found in different kinds of home appliances and electronics. The three way toggle switch allows you to control different sets of lights, fans, extractors and other electrical systems from one central point. Even though toggle switches are simpler than many of their counterparts, it is still important to understand the wiring diagram of a three way toggle switch – otherwise, mayhem can ensue.



When wiring up a three way toggle switch, there are certain necessities that must be taken into account. Even though the process may seem daunting at first, the steps needed to be taken to make sure that it works properly are quite straightforward and easy to understand. In this article, we'll guide you through the process of wiring up a three way toggle switch and explain the required components and connections.



Components List



A successful setup of a three way toggle switch involves several pieces of equipment, many of which are relatively simple to install but need to be done correctly to ensure a successful result. To begin the process, you’ll need the following components:




  • Three way toggle switch

  • Non-metallic enclosure

  • Unit box

  • Four gauge wire

  • Wire nuts

  • Screwdriver



Wiring Setup



To begin the wiring of your three way toggle switch, remember to cut the power supply to the device so as to avoid electric shock. Once that is done, start by taking the Unit box and drilling a pilot hole into it. Secure it to the non-metallic enclosure with the screws. Take the four gauge wire and connect it to the Unit box, leaving enough slack to extend up to the switch. Finally, connect the three way toggle switch to the Unit box and secure it to the wall in the desired location.



Connecting the Wires and Final Tests



Once the unit box has been secured in its place, the wiring needs to be connected to the three way toggle switch. Start by taking the two wires connected to the first switch and connecting them to the two lower screws. Make sure that the black wire is connected to the screw on the left while the red wire is connected to the screw on the right. Repeat the same process for the second and third switches. Next, attach the ground wires together with the wire nuts before testing the device.



Once the wiring and connections have been worked through, it is time to finally test the device. Turn on the power and take each switch in turn to test its functionality. If everything is working correctly, your three way toggle switch is ready to be used. If there are any issues with its performance, double check to make sure all the wires are properly connected.



In Conclusion



Installing a three way toggle switch is quite a straightforward process, provided that all correct steps are taken and each switch is wired correctly. As long as the proper steps are followed and the components are chosen correctly, any electrician should be able to complete the job without too much of a problem. With this easy-to-follow guide to the wiring diagram of a three way toggle switch, you’re bound to find success.
