You use two three-way switches to control the light, and wire it up as shown below: In this diagram, a normal piece of wire comes from the fuse panel to the first three-way switch. Understanding how the circuit works satisfies See the second image. The three-way switch is a variation of the standard single-pole switch, which controls a light only from one location.
You use two three-way switches to control the light, and wire it up as shown below: In this diagram, a normal piece of wire comes from the fuse panel to the first three-way switch.
Three-way switches allow for controlling a light fixture from two separate locations, these are usually used at the top and bottom of a flight of stairs or at two different entrances to a room.
Controlling a light with three or more switches. I noticed a significant crack in one of my kitchen walls. Three-way wire(which includes red, black and white wires) runs from the switch on the left to the switch on the right, with.
