How To Repair A Three Way Switch
How to Troubleshoot a 3 Fashion Switch? Do We Know....
Practice y'all take a big room that requires several switches? Or do you only love having more 1 switch for convenience? Whether it is the former or the latter, y'all will be needing a three-manner switch. This is a minor simply handy wall device that will make life easier for you.
What is a 3-Mode Switch?
A three-way switch is a lot similar your regular switches except that they come in pairs. Why? It's considering the purpose of a 3-style switch is for you to be able to turn on or off your lights and ceiling fixtures from two different places. This ways that if you tin plow on a light on one end of the room, you lot can also turn them off on the other cease. This is why yous don't run into any on/off labels on the actual switch.
A three-way switch also has a bulkier body due to its screw terminals. It has a total of three terminals and a footing spiral. Two of its spiral terminals are continued to the other switch with wires. These are called traveller wires. The other screw terminal is usually connected to the ceiling or lite fixture.
When to Troubleshoot a 3-Way Switch
When exercise yous demand to troubleshoot a iii-style switch? You don't have to troubleshoot a three-style switch all the fourth dimension. In fact, you don't even have to do this regularly as this isn't a software that needs updating and troubleshooting. However, there are times when your switches go lacking.
A common case when you need to troubleshoot is when the switches aren't working. Of course, this presupposes that your light seedling is in skilful status. If information technology is and the switches are non turning the lights on or off, then you have to troubleshoot. You may also notice simply one of the switches is faulty.
Some other instance is when the wires are not properly connected. Although you lot won't know this unless yous're an electrician, a non-functioning switch tin can be brought about by wrong wiring.
How to Troubleshoot a Three-Way Switch
How exercise you lot fix a faulty 3-fashion switch and so? While you're keen on fixing your three-way switch, yous still need to be sure what the problem is. Is it a defective switch, or is it bad wiring?
Fixing a Lacking Switch
To know if it's a defective switch, y'all need to test both switches. Follow these steps to know which one.
1. Toggle the first switch. Plough the light on.
2. Toggle the 2d switch. If you can plough the light on and off with this switch, this ways that the switch is working. Hither's a tip - a defective switch will not be able to control a light that is already on. Get out this 2d switch with the light turned on.
three. Now go back to the first switch. Turn information technology on and off. It works, then the trouble is not a lacking switch. Otherwise, that is the defective one.
Replacing a Defective Switch
When it comes to 3-manner switches, it is highly recommended that you supplant the two switches at the same time. The reason backside this is that when ane switch is broken, how much longer will the other ane last? Since both of them were installed at the same time, so the other volition most likely fail any time presently.
- First, turn off the power on the circuit breaker.
- Go to the iii switches and remove them.
- When you are able to access the wires, make certain that they are not touching or are close to each other. If you don't have an electrical background, you might get confused with the wires. To chop-chop place each wire, you tin mark them or add an identifier so that adjacent time, yous won't get confused likewise.
- Turn the power back on in the excursion breaker.
- You lot need to use a continuity tester for this part. Using this tool, check for ground on each wire. The ground wire is likewise called a "hot" or "alive" wire since this is where the electricity flows. For a three-manner switch, there should only be one live wire, and that is the common wire. If you found the live wire on one switch, there shouldn't be another live wire on the other switch.
- When yous find the live wire, go back to the circuit billow to turn the power off.
- Install a new switch to the terminal with the live wire. Connect the alive wire to the common terminal. Then, connect the traveller wires to the other two terminals. Close the new switch with all the wires inside.
- At present become to the 2nd switch and then accept off the old switch.
- Await for the common wire past touching one of the probes of the continuity tester to the wires. At that place should be a beep in one of those wires. The wire that beeps or registers a resistance is the mutual wire.
- Similar to what you did to the first concluding, connect the common wire to the common terminal. Then, connect the other traveller wires to their corresponding terminals.
- Adhere the new switch to the wall with all the wires inside.
Tips on Troubleshooting a Three-Way Switch
At first, troubleshooting a three-way switch seems similar a daunting task. For people who have no idea about electric wires and are uncomfortable with doing so, information technology's all-time to call a professional person.

Another tip is to mark the wires. This is easily overlooked by people since it'southward not that hard to identify a alive wire. However, y'all need to practise this not just now but also for your future troubleshooting tasks. Even if you don't marker the other wires, never forget to label the mutual wire. A coloured tape volition suffice.
And that'south how you troubleshoot a three-way switch. It's not that complicated, but you accept to be extremely careful.
