Wiring Diagram 4 Way Switch

A 4 way switch is a type of switch that controls the flow of electricity between two or more locations. It is commonly used in homes, offices, and other buildings to control lighting or other electronic devices. In this article, we will discuss the wiring diagram for a 4 way switch, including the materials needed, step-by-step instructions, and frequently asked questions.

Materials Needed

Before you start wiring the 4 way switch, it is important to gather all the necessary materials. Here is a list of materials you will need:

Materials Quantity
4 way switch 1
3 way switch 2
14/3 wire 1 roll (50 feet)
Wire nuts 4
Screwdriver 1
Drill with 1/2 inch bit 1

Make sure to have all these materials on hand before you start the wiring process.

Step-by-Step Instructions

Step 1: Turn off the Power

The first step is to turn off the power to the circuit you will be working on. This will prevent any accidents or injuries from occurring while you are working on the wiring.

Step 2: Prepare the Cables

Next, you will need to prepare the cables. Cut the 14/3 wire into three equal lengths, and strip about 1 inch of insulation from the ends of each wire.

Step 3: Install the First 3 Way Switch

Start by installing the first 3 way switch. This switch will control the light or device from one location. Connect the black wire from the 14/3 wire to the common terminal on the switch. Next, connect the red and white wires to the other two terminals on the switch.

Step 4: Install the Second 3 Way Switch

Next, install the second 3 way switch at the other location. Connect the black wire from the 14/3 wire to the common terminal on the switch. Connect the red and white wires to the other two terminals on the switch.

Step 5: Install the 4 Way Switch

Now it’s time to install the 4 way switch in the middle of the two 3 way switches. Connect the black wire from one of the 14/3 wires to one of the brass terminals on the switch. Connect the black wire from the other 14/3 wire to the other brass terminal. Connect the red and white wires to the two other terminals on the switch.

Step 6: Connect the Wires

Finally, connect the wires at each switch. Connect the white wires from each 14/3 wire together with a wire nut. Connect the ground wires together with a wire nut. Finally, connect the incoming and outgoing black wires to the common terminals on the 3 way switches with wire nuts.
