how to install three way switch - IOT Wiring Diagram

Installing a three-way switch can be an intimidating task for the average homeowner, but with the right instructions and supplies, even a novice can complete this project in just a few simple steps. A three-way switch allows you to control a light from two different locations within a room.

The first step in installing a three-way switch is to turn off the electrical current in the area where you will be working. This can be done by either turning off the main power switch in the breaker or unplugging the associated appliance. Once the power has been shut off, use a screwdriver to remove the existing wall plate cover and existing switch(s).

Next, carefully examine the wiring of the existing switch and identify the two wires that are connected to the switch. Next, attach the black (hot) wire from the new three-way switch to the terminal screws identified in step 1. Connect the remaining two wires, one from the incoming power source and the other from the light fixture, in an alternating pattern on the three-way switch’s terminals. Make sure all connections are securely fastened with wire caps. Lastly, install the new wall plate cover and turn the power back on.

You have now successfully installed your three-way switch. It is important to note that a professional electrician should be consulted if you encounter any issues while completing the project. With that said, a simple three-way switch installation can be a great way to save money and add a touch of convenience to your home.
