Wiring Diagram 3 Way Light Switch 2 Lights. I have two switches in my kitchen, one on each side, that each turn on two lights at the same time. Then you had this hallway with two ceiling lights.
A three-way switch is built and wired a Refer to the illustrations below for doing the rough-in wiring for each of these situations. In this wiring connection we use two way switches in which we have three terminals, in these terminals one is common and two for connection. we can use it for many connection using different connection methods. The white wire of the cable wiring is marked with black electrical tape, and is going to the switch.
The power source is via one of the light fixtures.
Then you had this hallway with two ceiling lights.
When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to. Three-way light switches control a light from two locations, such as from both ends of a staircase or hallway. How Three-Way Switches Work. by Marshall Brain.
