3-Way Switch Wiring Diagram
A 3-way switch wiring diagram is a schematic representation of the electrical connections needed to control a light from two different locations. The “power at light” variation of this diagram indicates that the power source is located at the light fixture itself, rather than at one of the switch locations.
To create a 3-way switch wiring diagram, power at light, follow these steps:
- Draw a horizontal line to represent the power source.
- Draw a vertical line from the power source to represent the light fixture.
- Draw two more vertical lines, one from each side of the light fixture, to represent the two switch locations.
- Connect the power source to one of the switch locations with a wire.
- Connect the other end of the wire to one of the terminals on the switch.
- Connect the other terminal on the switch to one of the terminals on the light fixture.
- Connect the remaining terminal on the light fixture to the other switch location with a wire.
- Connect the remaining terminal on each switch to the neutral wire.
Once the diagram is complete, it can be used to wire the 3-way switch circuit.

These key aspects provide a comprehensive overview of the 3-way switch wiring diagram, power at light. By understanding these aspects, you can safely and efficiently wire a 3-way switch circuit.
Power Source
In a 3-way switch wiring diagram, power at light, the power source is located at the light fixture itself, rather than at one of the switch locations. This is in contrast to a standard 3-way switch wiring diagram, in which the power source is located at one of the switch locations.
- Components: The main components of a 3-way switch wiring diagram, power at light, are the power source, the light fixture, the two switches, and the neutral wire.
- Examples: This type of wiring diagram is often used in situations where the light fixture is located in a difficult-to-reach location, such as a high ceiling or a closet. It can also be used in situations where it is desirable to have the power source located at the light fixture, such as when the light fixture is controlled by a dimmer switch.
- Implications: The location of the power source has several implications for the wiring of the circuit. For example, the length of the wires used to connect the switches to the light fixture will be shorter than in a standard 3-way switch wiring diagram.
Understanding the connection between the power source and the light fixture is crucial for properly wiring a 3-way switch circuit. By following the correct wiring diagram, you can ensure that the circuit is safe and functional.
Switch Locations
In a 3-way switch wiring diagram, power at light, the two switch locations are connected to the light fixture with wires. This is essential for completing the circuit and allowing the light to be controlled from both locations.
- Components: The main components of a 3-way switch wiring diagram, power at light, are the power source, the light fixture, the two switches, and the neutral wire.
- Circuit: The circuit is completed when the two switches are in the same position (both up or both down). When the switches are in opposite positions (one up and one down), the circuit is broken and the light is turned off.
- Control: The light can be controlled from either switch location, making it convenient to turn the light on or off from either location.
The connection between the switch locations and the light fixture is crucial for the proper functioning of the circuit. If the wires are not connected correctly, the light will not be able to be controlled from both locations.
Real-Life Examples: 3-way switch wiring diagrams, power at light, are commonly used in a variety of residential and commercial applications, including:
- Controlling lights from two different entrances to a room
- Controlling lights from the top and bottom of a staircase
