Connect to the First Switch:
Connect the power source’s hot wire to the common terminal of one of the 3-way switches. This is the starting point of the circuit. Use appropriate symbols for wires (solid lines) and clearly label them as “hot,” “neutral,” and “traveler.” This step lays the foundation for the entire system. A clear connection ensures the power source correctly feeds into the switching mechanism.
-
Connect the Traveler Wires:
Show the traveler wires connecting the two switches. These wires carry the signal between the switches. Label these wires as “traveler 1” and “traveler 2.” This is the crucial step that differentiates a 3-way switch from a simple single-pole switch. The accurate representation of the traveler wires ensures proper functionality of the system.
-
Connect to the Light Fixture:
Connect the common terminal of the second switch to the light fixture. Show the hot and neutral connections to the fixture. The correct connection of the neutral wire is crucial for safety and proper operation. This completes the electrical circuit, allowing the light to be controlled from both switches. The complete circuit is essential for understanding the switch’s functionality.
