The socket is used with a three way bulb containing 2 separate elements that are energized separately and then together as the switch knob is turned for varying degrees of light. To construct this setup we need 2-two way switches, here common terminal on one switch is connected with phase line and another switch common terminal connected to the lamp load, always prefer switch connection in the Phase line. The source neutral is spliced in the switch box with the white cable wire running to the neutral on the receptacle. For choosing wire color for your circuit, see later in this page.. In this arrangement, the connecting tab between the hot terminals remains intact. This will allow you to connect the first light as you described above, and to run this additional light from the same switch by utilizing the red conductor in the 3-wire as the “switched” conductor, and the black wire as the continuous hot wire. As I have already mentioned in the introduction paragraph, a two way switch is very useful in staircase lighting as you can turn on the light just before you start to climb the stairs and once you reach upstairs, you can turn off the light simply by toggling the switch placed near the top of the staircase. how to run two lights from one switch electrical online i know that if i was to run a light switch to only one light i would connect the black wire from the switch … One is an older method, which is not often used now-a-days an… Lastly, the combo switch can be used to control the built in receptacle itself, allowing it to function as a switched outlet.
