How To Wire A 4 Way Switch With 2 Lights

Two way switch can be operated from any of the switch independently means whatever be the position of other switch on off you can control the light with other switch.

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. 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. Two cubic inches are required by the national electrical code for each 14 wire. Connect one wire to the first switch in the box and the second wire to the other switch and connect the black wire from each of the lights to the other terminal on its respective switch.

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. This white wire is wrapped with black tape to mark it as hot. The white wire is marked with black at each splice to identify it as hot. I use simple elect.

This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following. With 2 lights it is spliced with the white wire running to the switches. 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. Attach the black and white blue traveler wires entering the 4 way switch box to the in terminals often the top terminals on the 4 way switch black on the left top pole and white blue on the right top pole.

I have a diagram for this light switch wiring method on my 3 way switch page. Connect the black wire from the switch to the black wire from the first light and the black wire coming from the second light. The source neutral wire is connected directly to the light fixture and the hot is spliced to the white cable wire running to sw1. 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.

I did not include grounding conductors on the 4 way switch wiring diagrams in order to keep them simple. There are two methods of making 2 way switching connection one is 2 wire control and another is 3 wire control. See tables 314 16 a b. 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.

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.
