4 Way Switch Circuits

Can any number of light circuits be placed between the switches on a 4 way circuit as long as it does not exceed the capacity of the circuit?

For example: A light between the first 3 way switch and four way switch and then 3 lights between the four way switch and second 3 way switch?

Thanks, Steve

Placing lights between the switches makes the wiring more complicated. It is easier to wire them from one end of the switches. Doing it the other way requires additional conductors in the cables.


Answers based on the National Electrical Code. Local amendments may apply. Check with your local building officials.

Maybe, If you are just talking about location the answer is yes, if you mean to connect the lights in between the switches the answer is no.

What you are describing can be done but it will require four wire cable for parts of the circuit. It is not the standard way to do it.

Wiring a multiple location circuit in deivance to standard or common practice could lead to people getting hurt. Just make a junction at the existing light and run the circuit to the new location..

I dont understand why you would want to "put a light between switches"
"Do it right the first time and avoid duplication of effort"

Your AHJ/Inspectors ALWAYS have the final say on ANY electrical code issue.
If in doubt, contact a licensed, experienced, reputable electrician to perform the work.

I understand now. The lights need to be at the end of the circuit.

Thank you for the clarification.

Let's imagine that you are all ready to begin installing your 3 way or 4 way switch setup with lights between the switches here and there.

Start by stringing just enough wires to operate one light preferably at one end or the other end of the light sequence physically. Then add two wire cable from that light to the remaining lights. Hint: It is best to run 3 wire cable non-stop between the switch boxes. Wire the first light from one of the 3 way switches in a 4 way setup (not the 4 way switch)


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
