3 way circuit


I'd like to install Dimmer, Light, Light, Dimmer. I'm told it can't be done. Is that true?

If you wire it correctley and use the right dimmers, it will work.

3 way circuit


Why not? I have dimmers on three ways and four ways all over the place. What are you exactly trying to do?

3 way circuit


Is you search the internet for installing a dimmer switch on 3 way circuit several say you can only use one. The directions also say only one dimmer can be used on a 3 way circuit.

Can you help me with a diagram?

Here's what I'm trying to do:

12/2 power to dimmer to recessed light to 2nd recessed light to 2nd dimmer

you need three wires between the two switches for a three-way to work. Dimmer or not. Some dimmers can only be dimmed at one end. (low end type) but many can be dimmed at both ends.

You need "smarter" dimmers. They are more expensive, but will dim at both ends.

You can do dimmers on both ends with electronic style dimmers. Standard dimmers utilize a mechanical on/off switch which won't allow a second dimmer to function.

Not necessarily.

Some master/slave style dimmers require power at both ends and only one control wire between them.

You biggest problem is TWO lights between the dimmers. This requires four wires between the lights. Dimmers are wired the same as switches. If you want two dimmers you must buy the type that allows two dimmers to be on the same circuit.

If one dimmer is on full the other has full control range
if one dimmer is on half the other has control from zero up to half
if I understand your question correctly.

Power failure memory
Superior RFI suppression
Front accessible service switch (FASS) to disconnect load power
Electrostatic discharge tested
Precise color matching across all controls

**For multi-location dimming, use (1) Lutron MA-600 and the Lutron MA-R in place of your 3-way and 4-way switches.

Cannot be used with regular 3-way and 4-way switches
