3 way light switch not working - IOT Wiring Diagram

Have you ever gone to flick a light switch and nothing happened? It’s such a mundane everyday activity that it’s easy to forget how powerful electricity is. Without it, we would be living in darkness and silence. That’s why when your three way light switch isn’t working, it can be very inconvenient.

Three way switches are used to control one light from two switch locations. Whether it’s a hallway, stairwell or any other area where you need to control lights from two different locations. Getting it repaired will require more than just a basic knowledge of electrical work. Start by testing the switch with a multimeter. Make sure that you switch between all three terminals and see if there is a steady voltage reading. If you get a steady voltage reading, then it is likely that your switch is fine.

However, if the switch does not have a steady voltage, then it’s likely that you have damaged wiring inside. In this case, it’s best to hire an electrician so they can assess the situation and make sure that the wiring is fixed properly. It’s important to remember that repairing damaged wiring should never be attempted without the proper protective gear and safety precautions. Electrical shock is no joke, and only a professional should do the job.

Overall, three way switches provide convenient ways to control lights from two locations. Unfortunately, when something goes wrong, repairing them can be difficult and potentially dangerous. Always make sure to get the help of a professional electrician if anything needs to be fixed.
