The Complete Guide: The Common Wire On A 3-Way Switch
In electrical wiring, a 3-way switch is a type of switch that can be used to control a light or other electrical device from two different locations. Each 3-way switch has three terminals: one common terminal and two traveler terminals. The common terminal is typically identified by a black or red wire, while the traveler terminals are typically identified by white or blue wires.
The common wire on a 3-way switch is the terminal that is connected to the power source. When the switch is in the "on" position, the common terminal is connected to one of the traveler terminals, which in turn completes the circuit and allows electricity to flow to the light or other electrical device. When the switch is in the "off" position, the common terminal is not connected to either of the traveler terminals, which breaks the circuit and stops the flow of electricity.
3-way switches are commonly used in hallways, stairwells, and other areas where it is desirable to be able to control a light or other electrical device from multiple locations.
