Wiring A Three Way Switch With Two Lights. 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. This option actually requires you to run two romex lines between the 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. The ground wire is pigtailed with a wire connector at the switch boxes and the ceiling box. This diagram shows connections when the power comes into the first switch on to the second switch and then on to two or more lights switched by the 3 way circuit.
The black and red wires between sw1 and sw2 are connected to the traveler terminals.
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. Two lights between 3 way switches power via a switch shown below are two fixtures between 3 way switches. Either way complete these five steps for 3 way light switch wiring. Option 1 is for power into the first switch wire to the lights and lastly wire from the light to the other switch.
