How To Wire A 4 Way Switch With 2 Lights

Some 4 way switches may have the in and out pairs opposite each other rather than top and bottom.

How to wire a 4 way switch with 2 lights. This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following. How to wire 2 way light switch in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches. Connect the black wire from the power supply to the white wire of the cable connected to the switch. How to wire a 2 way lighting circuit in this video i show how to wire a light that can be turned on and off with two different switches.

The white wire is marked with black at each splice to identify it as hot. The white or neutral wires bypass the switch so the one coming from the power source and the one from the light get spliced and capped in the box. At sw1 this marked white wire is spliced to the marked white running to the 4 way switch and at the 4 way it is spliced again to the marked white wire running directly to the common terminal on sw2. I have a diagram for this light switch wiring method on my 3 way switch page.

See tables 314 16 a b. Two cubic inches are required by the national electrical code for each 14 wire. Connect the black wire from the switch to the black wire from the first light and the black wire coming from the second light. A two wire cable c2 is run from the light to the first switch sw1 and a 3 wire cable runs between all the switches.

This white wire is wrapped with black tape to mark it as hot. There are two methods of making 2 way switching connection one is 2 wire control and another is 3 wire control. At sw1 it s spliced to the white wire running to the 4 way switch box where it s spliced to the white wire running to common terminal on sw2. I use simple elect.

I did not include grounding conductors on the 4 way switch wiring diagrams in order to keep them simple. The source neutral wire is connected directly to the light fixture and the hot is spliced to the white cable wire running to sw1. With 2 lights it is spliced with the white wire running to the switches. Run your cable from the first light to the second light.

Wrap a piece of black electrical tape around each end of this white wire to indicate that it is a hot wire rather than a neutral wire.
