  • Light - Light - Switch Wiring Question

    What is correct for wiring in this sequence?

    Light - Light - Switch

    I found the following diagram:

    Wiring a light switch where two lights are operated by one switch is demonstrated in this detailed wiring diagram.


    But, I don't need the two wires going out to the right for two more receptacles. If that is the case, do I need 12/3 wire between the lights?

    Thank you in advance.

    If supply power is coming into one of the lights first, then yes, you need to install 12/3 between the lights in order to be controlled by one switch. The switch is being wired in a switch loop fashion so the white wire is actually a hot wire and not a neutral wire. You'll need to mark it as so by coloring it at both ends using a black magic marker.

    Here's another link that'll show you how to install this type of circuit.

      Thank you. As you suggested, I would like to have the power go to one of the lights first to minimize the number of wires in the switch box. I have looked all over the internet for all of this information but had not found dan's page.

        Is there a switch box already in use that has wires going into it? If there is then you'd only be adding a 12/2-g cable to wire it switch=light=light.

        By wiring the switch as a switch loop instead just be aware that you will never be able to tap power from this switch as there will be no neutral wire available.

          For these lights, I am adding a new switch box to my kitchen. However, I appreciate the warning about not being able to tap power from this switch in the future. I did not think of that ramification.

          Thank you for all of your help.
