Illustration of a domestic lighting circuit with two-way switches. This system allows a single light to be controlled from two locations, for example, from the top and bottom of a flight of stairs. The live wire (L) carries current to the light bulb at a high voltage when the circuit is complete. The neutral wire (N) carries current away from the light bulb. | |
