Why is it called a 3-way switch?
Why is it called a 3-way switch? Circuits controlled by two (single pole, double throw) switches are called three-way by convention to distinguish them from circuits controlled by one (single pole, single throw) switch, which may be considered two-way (on, off).
What does a 3-way switch do in a circuit?
Three-way switches are commonly used to control a light fixture from two different locations. For example, a long hallway or stairway might use a pair of three-way switches at each end so that lights can be turned on when approaching one end of the hall or stairway, then shut off from the other end.
What is 2 way switch and 3-way switch?

What is 3 way and 4 way switch?
A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.
What is a four-way switch?
What is a 2 way switch used for?
What is a Two-way Switch? The two way (double-pole) switch is used to ON and OFF the light from two different locations and the switch is mostly used in the case of stairs, in rooms that have two entries. This type of switch is generally used in some home wiring systems and industrial applications.
