How to Wire a 2 Way Switch

In our daily life, we use two-way switches, but most people don’t know about the 2-way switch wiring, for that, I am gonna write about this switch wiring with a complete diagram. Most people think that in electric wiring we use 2-way switches only for stair circuits, but they are wrong because the uses of 2-way switches in electrical technology are so many. We use it in the Washing machine, We use it for two electric supplies etc.
