The electrical source is at the first 3 way switch and the hot wire connects to the common there. The circuit neutral is spliced at each switch box through to the light fixture using the white wire.

How are two 3 way switches connected to each other?

Two 3-way switches are connected to each other via traveler wires, only one of which is hot in any given switch setting combination. The 4-way switch connects in the middle of the two travelers. Each 3-way switch has a common terminal and two traveler terminals. [4] Master Electrician Expert Interview. 16 August 2021.

Where does the hot wire connect to the 3 way switch?

How do you wire a 4 way switch?

4 Way Switch Wiring with Four Switches Here two 4 way and two 3 way switches are used to control lights from four different locations. The two 4-ways are located between the two 3-ways and the traveler wires run from SW1 to T1 on the first 4-way. T2 from that switch is wired to T1 on the second 4way and T2 connects to the travelers on SW2.

How do you install a 3 way light on a light switch?

In order for the light to work properly, you have to install both wires (red and black) from the first 3-way switch on the brass screws (or terminals) and the same colored wires (red and black) from the second 3-way switch – on the dark (or black) screws (or terminals).

What color are the wires on a 4 way switch?

The wires that are in your white cable (that connects the switches) are color-coded. The terminals (or screws) of the switch are color-coded as well. There could be more 4-way switches involved, but in this setup, we will connect one 4-way switch in between two 3-way switches.

How do you test a 4 way switch on a refrigerator?

To test a 4 way switch, connect one probe to one traveler terminal in a pair and the other probe to one traveler terminal in the other pair.
