🔧 Understanding 3-Way Switch Wiring Basics
A 3-way switch wiring diagram PDF helps control a single light fixture from two different switches. Unlike a standard single-pole switch, a 3-way switch system involves:
- Two 3-way switches
- A light fixture (or multiple lights)
- Traveler wires (connecting the switches)
- Common terminal connections
📌 Key Components in a 3-Way Switch System
| Component | Function |
|---|---|
| 3-Way Switches | Allow control from two locations. |
| Traveler Wires | Carry current between switches (usually brass-colored screws). |
| Common Terminal | Connects to the power source or light (black screw). |
| Neutral Wires | Complete the circuit (usually white). |
| Ground Wires | Ensure safety (green or bare copper). |
