Before you begin anything with a three-way, Three way switch hook up must understand that in order for you to have a three-way circuit you must have three-way switches. They are not the same as a regular switch at all.

These are the extra ones....

And a four-way is very different again. You just need to overcome all those extra wires. Look at the diagram below. These are the extra ones. But wait, your 3-way switch has two extra screws. So basically, you just need to add those wires to those screws and both switches.

However on each 3-way switch, you have a black screw, this is the special one. On the power coming in from the panel, you would connect that black wire to the one black screw. And on the other switch, you would connect the black wire coming from the light to that black screw.

You connect all white wires together in each box. But of course, the light itself will need that white wire neutral to power up. All grounds are tied together and connected to each switch in the box it is in. Funny thing I was changing things on Three way switch hook up site the Three way switch hook up time you commented on this. They look good to me. I hope they are ok Three way switch hook up

This story features diagrams that...

Yes three ways switches on both ends. There are a few ways to wire a three way. Not just the way I show. Use the question section to where you can post pictures. In my garage, power comes into a junction box in the middle of the garage.

From that junction box a cable goes to the front of the garage where the switch is, another cable goes towards the back of the garage with several outlets daisy chained. These are what our shop lights plug into. The switch turns the outlets Three way switch hook up and off. I wanted to add a switch to the back of the garage where the door goes into the house so I can turn the lights on when i enter the garage from the house.

If I replace the current switch to a 3 way, I understand Three way switch hook up would need to connect the two 3 way switches with It makes sense to me how to wire the switch in the new location, but what about the switch in the old location—it does not have power coming in one way and going to a light.

Will I need to connect both black and both whites to the terminals the ones coming from the junction box and the ones going to the 2nd switch? Thank you so much for pointing that out. I have fixed that. Dominick — Thank you for the diagrams. In the top diagram — the diagram where the switches are labelled S1 and S2 — the wiring to the bulb is backwards.

For safety, the hot wire should always go to the tip of the bulb, and the neutral to the threads of the bulb. I bought the switch yesterday from Lowes. I will proceed with connecting my High to the dark screw, since you have seen this before.

Thank you for your response and video. That would really depend. And how old your switch is. I remember seeing some funky older switches before. My three way switch has the dark screw common across from a traveler and the other traveler Three way switch hook up the bottom of the switch where the common is in your illustration.

Three way switch hook up this a difference in brands of switches? Each light would just come off of each other. But watch this video.

Three way switch hook up Hi Dominick, How would I wire 2 lights to 2 3 way switches? Three way switch hook up have a light at the top of the stairs and a light at the bottom of the stairs. So i want to put a switch at Three way switch hook up bottom of the stairs and at the top of the stairs. A led as you know uses very little electric and just a little will give it some light.

First make sure you wired the light correctly. Meaning the hot is on the hot side. Try switching them around maybe. And make sure if you have a ground on the fixture Three way switch hook up it is connected. Dominick, I understand the basic wiring for a 3-way switch and your video helps to reinforce my understanding. My wife asked me to install new LED fixtures in the hallway. One is on a separate 2-way switch works fine and the other is connected to 3-way switches.

The power seems to be coming into the light and running into the switches. Would using 2 different switches matter? One is a reg switch on off and the other is a toggle.

Would this make it not work right? However watch my 3 way and 4 way switch videos. Dominick, my son thought he would help out in replacing the old fashioned up-down toggle on-off wall switches to the new fancy large fascia switches.

Here in lies the problem. He and his mom went and bought the wrong type switch. After burning up a few circuit breakers I put a stop to their effort as I was afraid they could have done worse.

When I went back to try and re-install the original switches till I get the correct ones, I noticed the wiring to be different and am Three way switch hook up to figure out the proper way of re-connecting the wires to the on-off switches. The circuit to the hallway uses 2 red wires and 1 black wire. The circuit to the staircase uses two red and two black wires.

In both circuits there are no white wires connected to any of the switches. Your help would be immensely appreciated. Great video and diagrams! Basically my problem at the moment…a wall was removed that had a 3 way switch on it, and the wire is in the attic now, but still attached to the other switch in the hall it controls light on fan, and single pole in same gang box controls fan.

The two switches in hallway were interconnected from a source receptacle. I would like to get power back to the switch from the attic…my question is this, if I jump into a existing box in attic and only have black and Three way switch hook up leads to connect to for power, what happens to my red wire going to the switch.

Yeah sure it makes sense. However it will stilled Three way switch hook up wire from the switches Three way switch hook up same way. But in this video I only show one of the ways to wire a 3 way. Enjoyed your video on the three way switch.

Where I am still confused is…. I mean, if there is the switch…then the light…. Need to know more. Where is the light? I enjoy your movies, and the way you explain things. However, take both switches out.

These are the extra ones....

What wires do you have in the other box? The black screw would be one for power and the other switch for power out to the light. Or this could be all done from one switch having just the 3 wire running to the other switch.

Wiring a 3-Way Switch

So lets say the wires you have in box one are all of them. Take the black wire from the other 3 way and connect that to the black wire to the light. And the wire from the light to the white from the power and the black from the power to the 3 way in the box Three way switch hook up all the wires.

Wondering what the difference would be when power source enters the middle switch. I understand the source and three wires using travelers as detailed in your video.

Wiring a 3 way switch

Now I have the two remaining wires from the cable going to the light. Where do I connect those? Do I connect the white with the Three way switch hook up whites?

Where would black be connected? Thanks for taking Three way switch hook up time to share your knowledge in an excellent video! Great videos, you give very good explanations in a simple manner easy to understand. These are the extra ones. But wait, your 3-way switch has two extra screws.

Three way switches have become extraordinarily popular because it adds convenience and ease to lighting in large rooms, hallways and staircases. For more flexibility, add a four way switch. Take your time, mark the wires rightly and you will not contrariwise be successful, you will interruption sane. The first thing you will need to determine is where the power is coming from and where the switches are positioned.

In this earliest example, the power is coming in to the first beat, flowing along to the b switch and ends at the light. The ground wire want always be attached in each box and flow right to the end fixture. This opportunity is very similar to choice 1 when wiring a 3 way switch.

Notice that there is a 3-conductor cable coming into the first box, then a 4-conductor cable going from left box to right box, then a 3-conductor cable going from the right box to the load. Now for wiring, lets assume you're looking at the switch just like it shows. The lower left screw is the common and gets the black wire from the source 3-cond.

The upper left screw gets the black wire from the right box 4-cond. The upper right screw gets the red wire from the right box 4-cond. The white wires tie together with a wire nut. The bare copper wires tie together with a wire nut.
