How to Identify a Multi-Way Switch

A multi-way circuit is where two or more light switches control the same light or set of lights. If there are two switches controlling the same light, they are both 3-way switches. Here is how to identify a 3-way switch.

Identifying

A 3-way multi-way switch typically has four screw terminals:

• Ground (often green)
• Common (typically black, different from the Traveler terminals)
• Traveler (typically gold and the same color as the other traveler)
• Traveler (typically gold and the same color as the other traveler)

Look for markings on the switch or the terminal color to help determine which terminal is which.

NOTE: Terminal color or style may vary. 

Labeling

Before Installing NOON, you will need to label the wires connected to the existing 3-way switch. The Line wire is connected to the Common terminal and T1 and T2 to the Traveler terminals.
