3. Wiring the Three-Way Switches
Now, focus on wiring your three-way switches. The configuration is slightly more detailed here:
-
At Switch One:
- Connect the hot wire (black) from the power source to the common terminal (usually marked as COM).
- Connect the traveler wires (typically red and black wires), which will run to the second switch, to the traveler terminals.
-
At Switch Two:
- Connect the travelers coming from the first switch to the traveler terminals of the second switch.
- From the common terminal of the second switch, run a wire back to the light fixture (this is often referred to as the switch leg).
Example Wiring Diagram
| Switch 1 | Switch 2 | Light Fixture |
|---|---|---|
| COM (Hot wire from power) | COM (Wire going to light) | Black (Hot wire from Switch 2) |
| Traveler 1 (Black wire to Switch 2) | Traveler 1 (Wire from Switch 1) | White (Neutral wire) |
| Traveler 2 (Red wire to Switch 2) | Traveler 2 (Wire from Switch 1) | Grounds joined |
When wiring, ensure all connections are securely twisted together and capped with wire nuts.
4. Finalizing the Connections
With all the wiring in place, now you can:
- Mount the switches back into their junction boxes.
- Secure the light fixture into its box, ensuring all wiring is safely tucked away.
- Replace any faceplates and screws.
5. Testing Your Work
Once everything is in place, it’s time to restore power to the circuit by switching the circuit breaker back on.
- Testing the switches: Flip each switch to ensure that both can successfully turn the light on and off. If only one works, double-check your connections, particularly at the switches.
Troubleshooting Common Issues
Occasionally, you may run into issues as you complete your project. Here are some common problems and their solutions:
Light Doesn’t Turn On
If the light doesn’t illuminate:
- Verify that the power is on at the circuit breaker.
- Check that connections are securely tightened and that wires haven’t slipped off.
Only One Switch Works
For instances where only one switch controls the light:
- Confirm that traveler wires are connected correctly between both switches.
- Ensure that the common terminals are properly connected at each switch.
