Difference between 2 way and 3 way switch

 There are several key differences between a two-way switch and a three-way switch. Here are six of the most important differences:

S.NO.	2- WAY SWITCH	3- WAY SWITCH
1.	A two-way switch has two terminals	A three-way switch has three terminals.
2.	A two-way switch is used to control a light or other electrical device from two different locations.	A three-way switch is used to control a light or other electrical device from three different locations.
3.	A two-way switch is typically used in a circuit with two wires.	A three-way switch is typically used in a circuit with three wires.
4.	A two-way switch is typically wired so that it can be operated from either end of the circuit.	A three-way switch is wired so that it can be operated from either end of the circuit as well as from a central location.
5.	A two-way switch has two different positions, "on" and "off."	A three-way switch has three different positions, "on," "off," and "intermediate."
6.	A two-way switch is simpler and less expensive than a three-way switch, which is why it is often used in residential and commercial buildings.	A three-way switch can provide more flexibility and control over the lighting in a space, which is why it is often used in larger or more complex electrical systems.
