How To Wire A 4 Way Switch With 2 Lights

This white wire is wrapped with black tape to mark it as hot.

How to wire a 4 way switch with 2 lights. A two way switch has 3 terminals. The white wire is marked with black at each splice to identify it as hot. To switch from two locations you ll need 2 two way switches and wire them together in a particular way. With 2 lights it is spliced with the white wire running to the switches.

2 way switch circuit diagram how to wire a 2 way switch two way light switch two way switch 2 way light switch with power feed via switch two lights the power source enters the switch box sb1 where the neutral is spliced through to the light fixture f1 where it is spliced to the light lt1 and via cable c3 to the second light lt2. 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. As you will see most 4 way switch wiring is placed between the wiring of two 3 way switches therefore a 4way switch is installed with two 3way switches. This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following.

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. 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. The source neutral wire is connected directly to the light fixture and the hot is spliced to the white cable wire running to sw1. To illustrate the 4 way switch wiring switch boxes and fixture boxes are not shown but are obviously required for every application.

Some 4 way switches may have the in and out pairs opposite each other rather than top and bottom. There are two methods of making 2 way switching connection one is 2 wire control and another is 3 wire control. This is very useful in a number places particularly hallways and stairs. 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.

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.
