1 way and 3 way dimmer switches

3 way dimmer switch has 2 red wires and 2 black wires and 1 way dimmer has 2 green wires and 2 black wires, one person at home depot told me it can be done to use 3 way for a 1 way switch !?
My question is "Can you use 3 way dimmer switch as a 1 way dimmer switch ?"

    Hi, thanks for the response. It's a long story I bought a lot of 5 dimmer switches on ebay its good deal for the price it is the same as those in this link

    I've googled alot and I've also seen alot of installation videos on youtube but none of them is tackling my issue wich is the red wires ? "What should I do with the red wires if I have only 2 green wires and 2 black wires coming from the single one way switch ?"
    If it can be done any help is appreciated, if not thanks anyway I'll use it only for a 3 way switch that I have buy a one way dimmer switches for the rest of switches.

    Thanks for all the comments and all the help, I was so happy with the results that instead of installing just 1 dimmer switch I end up installing 5 dimmer switches !!

    It's very nice and house look like a museum or movie theater or both, in short its worth it and I encourage everyone who has the money, time and patience to do it, but please follow the safety procedures first.

    Thank you.

Since a single pole, one way, switch only costs a dollar I personally would not do this but if you must:

Put the hot incoming wire on the dark colored screw, and the wire going to the switched device on the top right brass screw. It really doesn't matter, as the switch will work either way, you may just have to turn it over to have the "on" position up.

Good luck.

The answer to your question depends on the manufacturer and type of 3 way dimmer you are using... generally you can use a 3 way switch as a single pole switch, but whether or not this holds true with the dimmer you are using depends. Let me know what you are trying to acomplish and model numbers mfgs of what you have and I'll try and help

with a three way switch like this, you will have two traveller wires and a common wire. Look in the instructions for the switch or on the back of the device itself to see if there is a wire labeled "common" or "com". This common wire from the old switch hooks up to the common wire on the new switch. I did a bit of searching on the leviton 6602, but couldn't find anything specifically about the three way version (I would venture to guess, however, that the red wire on the old switch is the common). The common on one of the three way switches will always be a constant hot (or power) wire...the common on the other three way switch will be the "switch leg" or the wire that connects directly to the light. The two travellers go to the other two wires. Check the pamplet that came with the lutron device, it should show which wire is common and which are travellers.

I am replacing a two way switch with a two way Trimatron dimmer 6681 The dimmer has 1 black wire hot, 2 red wires and a ground (green) The box has 2 black, 1 red and 2 white What do you connect...

The best thing you can do in that situation is match the wire colors of the dimmer to the colors of the screw terminals on the switch you removed. Unfortunately, its too late for that - so here's my best guess: One of the black wires in the box will be coming from the same romex cable as the red wire. Take THAT black box wire and connect it to one of the red wires on the dimmer. Take the red box wire and connect it to the remaining red wire on the dimmer. Connect the black dimmer wire to the remaining black wire in the box. The two white connectors in the box get tied together - they don't get tied to the dimmer. And the ground (green) wire on the dimmer just connects to the bare ground connection in the box itself - or to the metal backbox - or cut it off and don't use it.

make sure your application is correct first,this switch is controlled from at least 2 locations,you cant put 2 dimmers on the same light,if you have taken the wires directly off the switch you will wire the white to the black of the dimmer and the 2 reds to each of the other wires,the white in this case is you pivot or constant hot,the other wires are the travelers

I am replacing an on-off switch, with the 90610-wv dimmer. The instructions says there should be 2 black wires, and possibly a green. The wire in the existing switch has 1 white 1 black, and a bare copper...

The important thing to remember is your switch has two wires.
Sometimes the colors vary a bit because of the specific circuit.
The green wire, when present, is a ground wire, and always connects to bare copper wire.

If your dimmer has two black wires, then connect dimmer-wires to either switch-wire
If the dimmer does not work, simply reverse the two wires.

If your dimmer has a red and black wire, then connect dimmer-black to switch-black, and dimmer-red to switch-white.
Again, if dimmer does not work, reverse the two wires.

Answer back if you have trouble, and I will help.

Ok the RED is Phase and the Black is Neutral... Green is Earth. you have an IN, Red wire, and an OUT Red wire, the rest just go color to color. So in the socket, one Red wire goes to one Red wire from the dimmer, the other Red wire in the socket, goes to the other Red from the dimmer, then Black to Black, and Green to Green. Be careful do NOT work on it live.

Trimatron 3 way push on off dimmer switch

One wire is the common and the other two are the travelers.The trick is to find which one is which.... If you can see into the electrical box check to see if one of the red wires and the black wire are from the same cable, if they are then more than likely those two wires are the travelers; you can also look at the other switch and see which two wires are on the brass colored screws, those would also be travelers. The common is usually the wire that is on the black colored screw. Once you figure out which wire is your common, I'm thinking that it is one of your red wires, you would attach that wire to the black wire on the dimmer and the other two wires to the 2 red wires on your dimmer.

Trying to hook up a dimmer switch it has a red black yellow and green wire the box has a black white and ground which wires get connected together?

For a single-pole installation:

1. Connect the 2 white wires together (one from the source and the other to/from the light fixture) - 2 wires
2. Connect the black wire from the source to the black wire on the dimmer switch - 2 wires
3. Connect the black wire to/from the light fixture to the red wire on the dimmer switch - 2 wires
4. Connect the ground wires - 3 wires
