Three-way switches are exclusively used in pairs, is this statement true or false?

The statement that three-way switches are exclusively used in pairs is true. Three-way switches are designed to control a single light or a group of lights from two different locations. When you want to achieve this functionality, you must use two three-way switches working together in a circuit. Each switch allows the user to turn the light on or off from either location, creating a convenient lighting solution in hallways, staircases, or large rooms.

While another type of switch can be used in conjunction with three-way switches for specific configurations, the fundamental operation requires two three-way switches to complete the circuit for controlling the light source. Therefore, this confirms the statement that three-way switches are typically used exclusively in pairs for their intended purpose.
