3 Way Switch Wiring Diagram: More Than One Light

This diagram shows connections when the power comes into the first switch, on to the second switch and then on to two or more lights switched by the 3-way circuit.

Note that this configuration is easiest to do when utilizing the first method of 3-way circuits discussed previously in our ‘Wiring a Basic 3-Way Switch’ article or diagram.

    Can you please show me a wiring diagram for a three way switch with the power coming to the first switch and then three lights and
    a three way switch at the end.

    thank you!!

    Why do you keep showing 2 switches there is only one switch and 4 lights. It is very confusing to the person trying to do this. STOP IT!!!!!

    It was wrong when I bought the house, now it is right. You rock!

    Ok, I think this is the diagram I want but just to be sure.  You’re showing two lights …. I have six lights.  Just keep extending the tap to the additional lights.

    I have a sourse to 1st 3-way switch, then 3 lights and finally another 3-way switch.  The problem:  I have a 14-3 wire running from the 1st switch, to each light and to final switch.  Anyway to make this happen?

    • Dave

      No you would need a 4 wire running between the two 3 way switches in this type of circuit.if you only had one lite in between the two 3 ways it would be possible,but with more than one you need a forth wire.

  • Dave

    here is one on this site

    not sure what you really have but did you look at this diagram, sounds like what you need from your discribtion
