3 Way Switch Electrical Wiring Diagrams. When you employ your finger or perhaps stick to the circuit with your eyes it may be easy to mistrace the circuit. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wire nut.
The power source also connects the terminal main three way switch and means that you need to have it spliced with a 3 way switch with the wire cable and that you will see the way that there is a neutral terminal with the light. When you employ your finger or perhaps stick to the circuit with your eyes it may be easy to mistrace the circuit. By correctly connecting two of these switches together toggling either switch changes the state of the load from off to on or vice.
Green for ground terminal.
At each switch in the above 3 way switch wiring diagram the black wire gets connected to the common copper or black screw. When wiring a 3 way switch circuit all we want to do is to control the black wire hot wire to turn on and off the load from 2 different locations. Both of the three way switching diagrams can be extended to four five or even more switches. Black live or hot wire green ground wire white neutral or common wire red terminal wire two 3 way switches.
