Pay close attention to the diagram to identify the specific terminals for the traveler wires on each switch. Accurate connection of these wires is crucial to the proper operation of the system. Failure to connect them correctly will result in a non-functioning circuit.
-
Connect the Switch Legs:
The switch legs are the wires that connect the switches to the light fixture. These wires complete the circuit and allow the light to turn on and off. The diagram indicates where to connect these wires to each switch. This process ensures the circuit is completed and enables the operation of the light fixture. Carefully follow the diagram, and ensure secure wire connections.
-
Connect to the Light Fixture:
Connect the switch legs to the light fixture. The connections will usually be labeled hot and neutral. Always double-check the connections before turning the power back on. Improper connections to the fixture may result in a faulty circuit or even damage to the fixture itself. Always use appropriate wire nuts to secure all connections.
