Control an electrical load from two different places

Control an electrical load from two different places

In our daily life applications often we need to control (on/off) electrical loads(like light bulbs, fans etc). I am giving you an example, suppose you are going from second floor to third floor. There is an electrical bulb for lighting the steps. When you are on the steps you need light but when you reach to the third floor then you need to switch off it. You switched on it when you were in second floor. So here you need one more switch to make the bulb off in third floor.

So, here you need to control the bulb from two different places.

What you need?

Two SPDT switches (single pole double throttle), wires, a load(take a LED),

The circuit I have maid-

Now toggle two switch and enjoy.
