What color wires go on a 3-way switch?

Figure A: 3-Way Switch Wire Diagram — Power to Light Fixture The black hot wire connects to the far right switch's common terminal. Red and blue wires link traveler terminals of both switches. The red wire, which is connected to the first switch's common terminal, leads back to the fixture.

Does it matter what wire goes where on a light switch?

What color wire goes where on a light switch? Because the switch terminals are interchangeable, it doesn't matter which wire you put on each. The key factor is that there's only one wire on each.

How does a 3 way lighting circuit work?

"3-way" is the electrician's designation for a single pole double throw (SPDT) switch. The switches must create a complete circuit for current to flow and the bulb to light. When both switches are up, the circuit is complete (top right). When both switches are down, the circuit is complete (bottom right).

Does the red wire connect to black or white?
