What type of switch is used to control lights from two different locations?

• A. Single-pole switch
• B. Double-pole switch
• C. Three-way switch
• D. Four-way switch

Answer: (C)

The use of a three-way switch is essential in controlling lights from two different locations. This configuration allows for the operation of a single light fixture from two separate switches, providing convenience and versatility in layout and design, especially in larger spaces like hallways or staircases. Three-way switches are designed with three terminals, which allows for the adjustment of the circuit path depending on the position of the switches. When one switch is toggled, it alters the flow of electricity through the circuit, which in turn can turn the light on or off, regardless of the state of the other switch. This functionality is particularly useful in locations where it is desirable to control lighting without having to go all the way to a single switch point. In contrast, single-pole switches can only control a fixture from one location, double-pole switches are designed for controlling devices that require two circuits, and four-way switches are used in conjunction with three-way switches to allow control of a single fixture from more than two locations. Therefore, the specific functionality of the three-way switch makes it the correct choice for controlling lights from two different locations.
