I have to turn on the light if any of the switch is on and I have to turn off the light if any of the switch is turned off

I have to turn on the light if any of the switch is on and I have to turn off the light if any of the switch is turned off.

Your stated requirements are contradictory. If one switch is on and the other is off then, according to your requirement:

  • "Turn on the light if any of the switch is on." So the light is on.
  • "Turn off the light if any of the switch is turned off." So the light is off.

You need to make up your mind.

If you want a two-way lighting system then you use two changeover switches.

The circuit of Figure 1 is probably what you want but not what you asked for.
