In a normal switch, the terminals are called “common” and “traveler.” The common terminal is where the power is sourced, and the traveler terminal allows power to flow through the switch to the light fixture. However, in a 3-way switch, there is an additional terminal called the “3-way” terminal. This terminal is used to regulate the power flow between the two 3-way switches.
Special Wire Requirements For Installation
To properly wire a Leviton 3-way switch, you will need a special wire known as “3-wire cable with ground”. This wire includes an extra red insulated wire, which plays a crucial role in establishing the connections between the switches and the light fixture.
The additional red insulated wire is essential for creating a three-wire circuit, which is necessary for the 3-way switch system to function properly. When selecting the wire, it is important to consider the appropriate wire gauge to ensure it can handle the electrical current required by the light fixture.

Terminal Connections In The “Up” Position
When a Leviton 3-way switch is in the “up” position, terminals 1 and 3 are connected, while terminal 2 is disconnected. This configuration allows the flow of power from the power source through the first switch and on to the second switch. When the switch is in the “up” position, it effectively completes the circuit, illuminating the light fixture.
It is important to properly tighten the terminal screws to ensure a secure connection. Loose connections can lead to flickering lights or electrical hazards. Double-checking the terminal connections in the “up” position is a critical step in the wiring process.
- Tightening terminal screws is important for a secure connection
- Loose connections can cause flickering lights or electrical hazards
“Properly tightening the terminal screws and double-checking the connections in the ‘up’ position are critical steps in the wiring process.”
Terminal Connections In The “Down” Position
Conversely, when a Leviton 3-way switch is in the “down” position, terminals 2 and 3 are connected, while terminal 1 is disconnected. This configuration breaks the circuit between the switches, effectively turning off the light fixture. By alternating between the “up” and “down” positions of the switches, users can easily control the illumination of the light from multiple locations.
Similar to the “up” position, securely tightening the terminal screws is essential to avoid any potential hazards. A thorough inspection of the terminal connections in the “down” position is vital to ensure a successful installation.

Frequently Asked Questions
How a 3 way switch is wired?
A three-way switch is wired by using a three-wire cable that connects the left switch to the right switch. The three wires in the cable include a red wire, a black wire, and a white wire. The white wire functions as the ground and the red and black wires carry the output from the terminals in the left switch. From the right switch, a standard sheathed cable is used to connect to the light fixture, allowing the electrical current to flow and illuminate the light as desired.
What is a 3-way switch with 3 terminals?
A three-way switch with three terminals is a type of electrical switch used to control a single light fixture from multiple locations. The switch has three screw terminals, one of which is the common terminal, distinguishable by its darker color. The other two terminals, typically referred to as the traveler terminals, are of the same color. By properly connecting the wires to these terminals, the three-way switch allows for the light to be turned on or off from any of the connected locations, providing flexibility and convenience in lighting control.
How do you wire a 3-way switch for a single?
To wire a 3-way switch for a single pole setup, start by disconnecting one of the traveler wires from the switch. Then, connect the remaining traveler wire to the common terminal along with the hot wire. This configuration ensures that the switch functions as a single pole, allowing you to control the light or device connected to it from a single location. Keep in mind that if the traveler wires are connected to the two traveler terminals instead of the common and one traveler terminal, the switch will not work as a single pole.
1. What are the necessary steps and precautions to follow when wiring a Leviton 3-way switch?
When wiring a Leviton 3-way switch, there are a few necessary steps and precautions to follow. First, turn off the power to the circuit at the main breaker panel to ensure your safety. Next, identify the wiring of the existing switch and note the positions of the wires, particularly the common wire which is usually a darker-colored screw terminal.
To wire the new Leviton 3-way switch, connect the common wire to the dark-colored screw terminal on the new switch.
