How do 3 way switches 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).
