The wiring for a 3-way switch setup, enabling control of a single light fixture from two different locations. The power source feeds into one switch and connects via a 2-wire cable to the fixture, while a 3-wire cable connects the two switches. The red and black wires act as "traveler" wires, allowing the switches to alternate control. The white wire is re-marked as "hot" to denote it’s carrying power, deviating from its usual neutral role. The common screw, typically copper or black, connects the hot wire on each switch. Ground wires (not shown) should be attached for safety at each box. This setup is ideal for large rooms, stairways, or hallways where multiple entry points require switch control.

A 3-way switch wiring configuration for controlling multiple lights between two switches. The setup allows for control of the lights from two separate locations. The power source connects to one of the 3-way switches, and the electrical circuit runs through the lights to the other 3-way switch. It uses 3-wire Romex with ground (labeled 12-3) to connect the switches and fixtures, with traveler wires linking the switches. Black tape on some white wires indicates they are used as hot wires rather than neutrals. This configuration is common in hallways or large rooms where lights need to be controlled from multiple points for convenience.
