In my dining room, I currently have a switch configuration that functions as follows:

  • Switch 1: when toggled, turns light on/off
  • Switch 2: when toggled, turns Switch 1 on/off

Can I have 2 dimmers or 1? If so, would I use 3-way or 1-way? Currently, both switches have 4 wires running to them, each.

Note: House was built in 2013.

  • By four wires, do you mean black, red, white, and bare, or black, red, blue, white, and bare?

Lutron makes 3 way switches for this set up that allow dimming. I just installed one set in my basement. One dimmer will be the base and the other talks to it. Here is what I have - Lutron Dimmer Set. With 4 wires running everywhere you should be set to install these.

    I am finding that as a STEP 0 to my dimmer installation, I need to resolve the problem of my switch configuration. My research has led me to the conclusion that my initial 3-way switch configuration was wrong.

  • That is a different question then. You asked how to add dimmers for a switch that controls another. Just ask another question for your current issue. We would just need to know where power is coming for the two switches.

  • When I initially asked the question, I didn't know that my original configuration wasn't a best practice and in most cases a mistake.
