3 Way Switch Single Pole Wiring Diagram. A three-way switch is built and wired a little differently than a conventional single-pole light. It should also help in understanding the functions of each type of switch.
Typically, you wire the power source to the common on one switch and the fixture to the common on the other. These diagrams illustrate how to wire a pair of three-way light switches in three different situations. The three-way switch is a variation of the standard single-pole switch, which controls a light only from one location.
A three way switch is a single pole double throw switch.
Two three way switches can be connected to turn on/off a hallway light from either end of the hallway for example.
But with many switch and device arrangements. For the instructions below, we're assuming that you are converting an. Otherwise, this may confuse you a little.
