This image illustrates a two-way staircase switch wiring diagram, commonly used to control a single light from two different locations, such as the top and bottom of a staircase.
How It Works:
- The Live (L) wire from the 220V AC power supply is connected to the Common (COM) terminal of the first two-way switch.
- Two traveler wires (L1 and L2) connect the corresponding terminals of the first switch to the second switch.
- The Common (COM) terminal of the second switch is connected to the light bulb.
- The Neutral (N) wire is connected directly from the power source to the light bulb.
Operation:
- Flipping either switch changes the electrical path between the traveler wires.
- If the circuit is completed, the light turns ON.
- If the circuit is interrupted, the light turns OFF.
- This allows the same light to be controlled independently from two separate switch locations.
Typical Applications:
- Staircases
- Hallways
- Long corridors
- Bedrooms with two entrances
- Large rooms requiring multiple control points
