Two-way electrical switches control lights from more than one location. They are commonly found in hallway, where a light or several lights need switches at different parts of hallway. All you have to do is wiring the two-way switches at the locations you would like to have a switch. Then you have the convenience of different switches that turn on/off the same light.
