Three-way switches can be wired in a number of different ways depending on where they are located relative to the light fixture in the circuit cable runs.
How does a 3 wire switch work. The goal is to place two switches at separate locations which control the exact same device. Hook the black wire to the bottom terminal on the switch. For example they can be arranged so that the feed cable runs to the first three-way switch then to the light fixture box then to the second three-way switch.
A three-way switch is fundamentally different in its operation from a regular two-way switch. White denotes neutral a current carrying wire that is bonded to ground in the circuit breaker panel. And if you flip either.

This 3 way switch wiring diagram shows how to wire the switches and the light when the power is coming to the light switch. With these diagrams below it will take the guess work out of wiring. This is where the travelers are connected.
Replace any regular switches with the 3-way switches. The black and white wires are insulated while a bare third wire acts as the grounding wire for the circuit. If the switch is down then terminals 2 and 3 are connected.
Another dead giveaway of a three-way switch is the absence of On and Off markings. How to wire a 3-way light switch and connect two 3-way switches to an existing or a new light fixture is a DIY project most homeowners can do on their own. This cable consists of an outer plastic sheath white in this picture with three wires inside.
The typical 3-Way switch wiring has two screw terminals at one end of the switch. The source is at the SW1 where the hot is connected to the common terminal and the neutral spliced through to the neutral on the outlet. A 3-way switch will not have the words on or off written on it.
You must completely forget about the notion of a switch being a simple openclosed circuit and look at the diagram of the circuitry of this modern alternative. Push the switch into the box and secure it with screws at the top and bottom. There is the pin which connects to the load we are going to power.
You can also see that if you flip either switch the light will turn on. Assume that with the switch up terminals 1 and 3 are connected as shown above. There is the pin which receives the power.
Turn on the power and test the switch. A loose or broken wire could explain why the switch doesnt work. When the switch is off the connection between these two wires is broken and the fixture gets no electricity.

This is known as the common screw and its usually black instead of brass or silver. A quick look at how to wire a 3 way switch commonly used inside vehicles project boxes and so onIm planning to use this switch in an upcoming video and f. Common practice in wiring a multiswitch circuit is to use two-conductor black and white cable from panel to the first switch and then three-conductor black red white cable between pairs of switches.
In this diagram the incoming hot wire attaches to the first switchs common dark-colored terminal. This might seem intimidating but it does not have to be. Traveler wire terminals - These are located on each side of the switch towards the top of the switch.
The two hot wires of three-wire cable connect to a pair of brass-colored traveler terminals on each switch. When disconnecting the wires mark the wire on the black or dark colored screw as common. Before you start installing take a look at your new 3-way switch to identify all of the terminals that you will be connecting wires to.

If the wires are stabbed into the back of the switch insert a small flat head into the slot above the wire to release. Below are the 3 pins that form electrical connection with a circuit each described with their function in the circuit. Pick the diagram that is most like the scenario you are in and see if you can wire your switch.
Now these are the 3 pins which establish electrical connection to the circuit we are wiring the rocket switch to. The opposite end of the switch has one screw terminal which may be a different color as seen here in this photo.

Take a closer look at a 3 way switch wiring diagram. You can see if you trace through the wires and the switches that in the previous figure the light is off. A three-way switch is designed to work in tandem with another three-way switch to allow you to control a fixture from two different locations.
