3 Light and 3 Switches Wiring Diagram is a simple construct of electricity with three switches, each controlling one of the three light bulbs respectively. This kind of circuit is widely applied at both residential and schooling places and in small offices. All the switches are in series with the respective bulbs, thus they can be operated separately. It makes fault finding easy, saves energy and maintenance is easy. This arrangement operates on phase-live wires in which they do pass through the switches and common neutral line returns. It would be perfect in situations which individually require control of each light-like a bedroom, hallway or classroom. The guide contains a plain schematic, a table of the input-output connections, and a description of the basic wiring formula to assist an average DIYer and an electrician.

| Switch No | Input (Live) | Output (To Bulb) | Connected Bulb | Output (To Neutral) |
|---|---|---|---|---|
| S1 | 230V | 230V | Bulb 1 (L1) | 0V (Neutral) |
| S2 | 230V | 230V | Bulb 2 (L2) | 0V (Neutral) |
| S3 | 230V | 230V | Bulb 3 (L3) | 0V (Neutral) |
