A traveller wire is one of two or four electrical wires used to power a multi-way lighting circuit. They are essential components of modern households, allowing a fixture to be controlled from multiple switches. In a three-way switch, two traveller wires connect to the two lighter-coloured brass screws on the switch, known as the traveller screws. These wires carry electrical current and are typically black or red, but can also be pink or violet. The easiest way to identify them is to double-check the wire colour. Alternatively, a multimeter can be used to test for resistance.

What You'll Learn
The wire colour can be checked to identify the traveller wire
In a three-way switch, the two traveller wires connect to the two lighter-coloured brass screws on the switch, also known as the traveller screws. In a four-way switch, there will be two sets of two traveller wires connected to four brass screws.
Another way to identify traveller wires is by using a multimeter to test for resistance. Set your device to resistance, often shown as the letter omega (Ω), and then measure the wires. The ones that read 0.00, or any number less than one, are the traveller wires, as there is no resistance.
It is important to note that any electrical work can be complicated and dangerous. Always shut the power off at the breaker before performing any work and consult a professional electrician if you are uncertain.

A multimeter can be used to test for resistance
To identify a traveller wire, you can use a multimeter to test for resistance. Traveller wires are hot wires that carry electrical current between the two switches in a multi-way switch. They are typically black or red, but can sometimes be pink or violet.
To test for resistance, first turn off the power to the circuit. Then, set your multimeter to resistance, which is often shown as the letter omega (Ω). Insert the black test lead into the COM jack and the red lead into the VΩ jack. Connect the test leads across the component being tested, ensuring good contact between the test leads and the circuit.
By measuring the resistance, you can determine the resistance between the two probes of the multimeter. If the multimeter displays 0.00 or any number less than one, it indicates that there is no resistance (good continuity), and the wire is a traveller wire.
It is important to note that measuring resistance with a multimeter can be done on an analogue or digital multimeter. Analogue multimeters require additional steps, such as zeroing" the meter by connecting the two probes together to create a short circuit before taking measurements. Digital multimeters provide a direct reading of the resistance measurement and are generally faster and easier to use.
Additionally, it is advisable to measure resistance when components are not connected in a circuit. Measuring resistance in a circuit can lead to inaccurate readings due to the influence of other components. Remember to ensure that any capacitors in the circuit are discharged before taking measurements.
By following these steps and guidelines, you can effectively use a multimeter to test for resistance and identify traveller wires in a multi-way switch.

The traveller wire is interchangeable with the terminal screws
The traveller wire is one of two or four electrical wires used to power a multi-way lighting circuit. It is interchangeable with the terminal screws.
In a three-way switch, the traveller wire connects to the light fixture, turning it on. Flipping the other switch sends electricity through the other traveller wire to the light fixture. Flipping the opposite switch again breaks the circuit, shutting the fixture off.
In a three-way configuration, two traveller wires connect to the two lighter-coloured brass screws on the switch (known as the traveller screws). These screws offer two different paths for power to move from one switch to the other. The traveller screws are interchangeable with the terminal wires.
In a four-way switch configuration, there will be two sets of two traveller wires connected to four brass screws. Two of these wires are for incoming power, and two of them are for outgoing power. The traveller wires are interchangeable with the terminal wires.
The traveller wire is a hot wire, meaning it carries an electrical current. It is typically black or red, but can also be covered in sheaths more closely resembling pink or violet colours.

The traveller wire is hot and carries electrical current
Traveler wires are found in multi-way light switches. They carry electrical current between the two switches in a multi-way switch. They are hot wires and are typically black or red, though they can also be pink or violet. They are essential components of a modern household.
The purpose of traveler wires in a three-way switch or multi-way circuit configuration is to allow a fixture to be controlled from multiple switches. When you flip one of the switches, it sends power through one of the traveler wires to the light fixture, turning it on. When you flip the other switch, it sends electricity through the other traveler wire to the light fixture. When you flip the opposite switch again, it breaks the circuit, shutting the fixture off.
In a three-way configuration, two traveler wires connect to the two lighter-colored brass screws on the switch (known as the traveler screws). These screws offer two different paths for power to move from one switch to the other. In a four-way switch configuration, there will be two sets of two traveler wires connected to four brass screws.

When you measure the wires, the ones that read 0.00 (or any number less than one) are the traveler wires, as there is no resistance (aka good continuity).

The traveller wire is connected to the light fixture
The traveller wire is an essential component of a modern household. It is one of two or four electrical wires used to power a multi-way lighting circuit. It allows a fixture to be controlled from multiple switches. When you flip one of the switches, it sends power through one of the traveller wires to the light fixture, turning it on.
In a three-way switch, the traveller wire is connected to the light fixture by first being attached to one of the two lighter-coloured brass screws on the switch (known as the traveller screws). These screws offer two different paths for power to move from one switch to the other. The traveller wire then carries the electrical current from one switch to the other.
In a four-way switch, there will be two sets of two traveller wires connected to four brass screws. Two of these wires are for incoming power, and the other two are for outgoing power. The traveller wires are typically black or red, but they can also be covered in sheaths that make them look more pink or violet.
To identify the traveller wires, you can double-check the wire colour or use a multimeter to test for resistance.

A 3-way switch has three terminal screws plus a ground screw. Two of the terminals are a light colour and are called travellers. The single dark-coloured screw is known as the common terminal. The ground screw is usually green.
Before disconnecting any wires on the old switch, find the wire attached to the common screw terminal and label it with a piece of tape. Then, you can disconnect all three wires from the switch, as well as the ground wire.
