Wiring 2 way light switch junction box. This 3 way light switch wiring diagram shows how to do the light switch wiring and the light when the power is coming to the light fixture. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2 way switch and a black wire from the other screw on the 2 way switch going to the load light ceiling fan etc. The essence of the wiring configuration is for one hot feed wire entering the switch box to be split so that it feeds both switches which in turn feed hot wires in cables that lead out to two separate light fixtures. In the above 3 way switch wiring diagram at each switch the black wire gets connected to the copper or black screw. 3 gang intermediate light switch.
