how to fix a 4 way switch - IOT Wiring Diagram

Modern homes are often outfitted with helpful electrical switches, like four-way light switches. Four-way switches are handy because they allow you to control one light fixture from the switch in two different locations. Unfortunately, however, four-way switches can sometimes break or malfunction.

If you’ve got a broken four-way switch, don’t despair: the solution can be simple—and cheap! Before you resort to calling a professional electrician, try to assess the problem yourself. First, unplug all devices connected to the switch and turn off the power to the entire circuit. Once the power is off, you’ll be able to access the screws and wires behind the switch plate without fear of electrocution.

Inspect the existing wiring for any issues. If there’s a loose connection, tighten the wire nuts; if the wires are frayed, it may be necessary to replace them. You can also check to make sure the wires are correctly connected according to the diagram on the new switch. Remember that four-way switches are always connected together in a circuit so to connect the first switch to the second, you’ll need a three-way wire. If everything looks in order, all that’s left to do is install the new switch—which should be a breeze with the existing wiring already in place.

Replacing a four-way switch isn’t as daunting as it may seem. With a few basic tools and instructions, anyone can repair their own switch quickly and safely. So don’t hesitate to take on the task yourself; you’ll save money and get back on your way to enjoying the convenience of a four-way light switch in no time!
