Wiring Diagram For Three Way Switch With Multiple Lights

Wiring diagram 3 way switch with light at the end in this diagram the electrical source is at the first switch and the light is located at the end of the circuit.

Wiring diagram for three way switch with multiple lights. In the ceiling light fixture electrical box one black wire from a 3 way switch gets connected to the black load wire on the light fixture. Wiring a 3 way switch with multiple lights in this circuit two light fixtures are shown but more can be added by duplicating the wiring arrangement between the fixtures for each additional light. Below i ve shown two variations of wiring multiple lights between 3 way switches. Option 2 is for power into the first switch but then wires run separately from the first switch to the lights and from the first switch to the second switch.

Here the source is at the first switch sw1 and 3 wire cable runs from there to the first light l1. Now discussing 3 way light switch wiring diagram as also discussed above the color codes of the wires as having three insulated conductors as black as hot red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires. In the above 3 way switch wiring diagram at each switch the black wire gets connected to the copper or black screw. This option actually requires you to run two romex lines between the lights.

3 way switch diagrams for multiple light fixtures. Three wire cable runs between the switches and 2 wire cable runs to the light.
