Q
A: A typical diagram shows a power source, two 3-way switches (each with a common terminal and two traveler terminals), and the light fixture. It also displays the wires connecting these components: the hot wire from the power source, the neutral wire (which typically connects directly to the light fixture and the switch box), and the traveler wires connecting the two 3-way switches. Each component is represented by a standardized symbol for clear understanding. The arrangement of these components and their connections illustrate how the switches operate together to control the light.
Q
A: The three terminals accommodate the hot wire from the power source (common terminal), and two traveler wires which carry the signal between the switches to control the light. These traveler wires allow both switches to operate independently, turning the light on or off from either location. The common terminal connects to the power source, providing power to the light through the traveler wires and the second switch. The configuration of these terminals is critical to the operation of a 3-way switching system.
Utilizing a 3-way light switch wiring diagram is crucial for correct installation, maintenance, and troubleshooting. Understanding the diagram allows for the correct connection of wires and ensures the light fixture functions as intended from both switch locations.
