Diagram Of Wiring A 3 Way Switch. Red and blue wires link traveler terminals of both switches. The two wire line cable goes into one switch box and the two wire load cable goes into the other switch box.
The electricity source is connected to the 3 way switch first. Whichever way you prefer wiring a 3 way light switch is easy when you follow our 3 way switch wiring diagram. 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.
The black hot wire connects to the far right switchs common terminal.
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. All three switches are connected together by a three core and earth control cable. Leviton 3 way switch diagram wiring diagram is the graphical representation of a complicated electric circuit. Black for live or hot wire.
