Three Way Switch Wiring Diagram Power At Light. Step by step instructions on how to wire a switched outlet. The hot source is spliced to the white wire which should be marked as being hot with black tap and run through to the common terminal of sw1 and from here the hot from the light is spliced through to the common terminal of the second 3 way switch sw2.
The black hot wire connects to the far right switch s common terminal. 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. 3 way switch wire diagram power to light fixture in this diagram power enters the fixture box.
Red and blue wires link traveler terminals of both switches.
A three way switch is built and wired a little differently than a conventional single pole light switch. Red and blue wires link traveler terminals of both switches. 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. These diagrams illustrate how to wire a pair of three way light switches in three different situations.
