  1. Dave Rongey says:

    Hi Dan,
    Yes. Two 3way dimmers may be wired to control a set of lights. Depending on the brand of switches you select, the switches will be wired as a Master and Slave configuration, or the conventional dual 3way switch configuration.
    Thanks for sharing your dimmer switch project with us,
    Dave

  2. Dan Rubin says:

    I am wiring my basement to have a 3way dimmer switch. Can I use two 3 way dimmer switches to control the same set of lights?

    Hi Dave,
    Just installed Qty 10 dimmable LEDs in my kitchen GU10s 4W, Now my wife wants me to dim them and I have looked at LED dimmers on the net. I see you need to replace the second two way switch with a slave, but the slave only has two wires? How does my existing wiring correspond with that ie Red common or live, Blue = L1 and Yellow = L2

    Many thanks
    Alex
