Wiring A 3 Way Switch Diagram For Two Lights. Connect live or a hot wire to the common or black terminal of the first switch. This is the new method to make a 2 way switching connection as it is slightly different from the two wire control method.
In this light switch wiring diagram the power feed joins the circuit via the light fixture where a two wire cable c2 runs from the light to the first 3 way switch sw1 and a 3 wire cable c3 joins the two switches. Red and blue wires link traveler terminals of both switches. 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.
Two lights between 3 way switches with the power feed via one of the 2 lights one switch diagram switches 2 lights line in through two lights.
In this diagram power enters the fixture box. Usually the third wire passes the middle intermediate switch but is joined in a separate terminal block. Use black and red wires to connect traveler or brass colored terminals of the first switch and the second switch. 3 way switch wiring diagram line to light fixture in another configuration the power supply enters the fixture first goes into one switch and finally terminates at the other switch closing the circuit.
