How To Wire A Three Way Switch With Multiple Lights

How to wire 2 way light switch in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches.

How to wire a three way switch with multiple lights. Either way complete these five steps for 3 way light switch wiring. 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. Turn off the correct circuit at your electrical panel. Wiring a 3 way switch isn t that difficult.

Option 1 is for power into the first switch wire to the lights and lastly wire from the light to the other switch. It s likely you ll also need to replace the existing switch box with a larger one to accommodate the extra wires for the 3 way switch. Add an electrical box for the second 3 way switch in the basement. Connect the black wire to the black wire on the light the white wire to the white one on the light and the bare one to the ground wire or the ground screw.

Here the source is at the first switch sw1 and 3 wire cable runs from there to the first light l1. This option actually requires you to run two romex lines between the lights. If you want to add a fixture you ll need an extra cable in the box that goes to that fixture. Connect one wire to the first switch in the box and the second wire to the other switch and connect the black wire from each of the lights to the other terminal on its respective switch.

Two 2 wire cables c3 and c4 run between the fixtures and a 3 wire cable c2 runs from the second fixture f2 to the second 3 way switch sw2. First run a 2 wire cable from the wall power to the black screw on 1 of the switches. 3 way switch multiple lights between switches below i ve shown two variations of wiring multiple lights between 3 way switches. To wire a 3 way light switch you ll need 2 3 way light switches 2 2 wire non metallic cables 1 3 wire non metallic cable and 2 6 inch grounding wires.

The answer to how it works is to have an extra hot wire that runs between the two switch boxes. In other words a 3 way switch is made up of one light that s controlled by two separate switches. This first step will eventually send power directly to the light fixture. Wire nut the neutral white wires together.

The most important rationale is that there are several ways that a three way switch can be wired. The white or neutral wires bypass the switch so the one coming from the power source and the one from the light get spliced and capped in the box.
