    Three way dimmer switch for one of three switches: which switch?

    I know questions related to this have been asked before, but I am a bit more of a novice than others. So I need some more help than what I could find from other answers.

    I have a few lights controlled by three switches. I would like to install a dimmer. I do not need dimmers on all three switches. One dimmer on one switch will be fine. I have read that I can use a three-way dimmer switch to replace one of the switches. However, I believe it needs to be on only certain switches? I do not have any electrical diagrams of the house. My questions are:

    1) Can I use a three way dimmer for a light with three switches (one location only)?

    2) How do I know which switch to use?

    Thanks!

    1) Yes. If you want to keep the existing mechanical switches you can just replace one of the 3-ways. You will be able to dim from 1 location and have on/off control from the other two.

    2) If you have toggle-style you will want the Ariadni AYCL-153-xx. If you have decorator style (big paddle) you will want Diva DVCL-153.

    Dimmers and LEDs don't always get along. You can check the Lutron site lutron.com/led or the bulb manufacturer site to see if they are compatible.

    Your circuit has a 3-way switch on either end and a 4-way in the middle. Either of the above dimmers can replace either of the 3-way switches.

    Thank you for the response!

    How will I tell the 3 way switches from 4 way one? And does it have to be those specific dimmers? Or can it be any Lutron 3-way compatible dimmer?

    3-way switches have 3 terminals/screws - black, brass and brass. The stab-in terminals are connected to the screw inside the switch so they don't count as a separate terminal.

    4-way switches have 4 terminals/screws - typically 2 brass and 2 silver.
