![]() ![]() Types of Wire Cable Used in 3-Pole Switches In essence, a 3-way switch is a toggle switch. However, they are not labeled “OFF” or “ON,” because they either allow or stop the electrical current based on the other switch position in the setup. Individual 3-way switches resemble single-pole switches. A 3-way switch setup will even work with a dimmer switch, as long as the dimmer switch is designed for 3-way wiring. That’s just one instance in which 3-way switches (also known as 3-pole switches) are handy: These switches allow users to turn on a centrally located light from different sides of a room, or from the upper and lower ends of a stairway. It’s no fun to come home late at night and stumble to the other side of a dark room looking for the light switch. ![]() ![]() RELATED: Buyer’s Guide: The Best Voltage Testers What is 3-way switch wiring?
