I am very new in electronics.
I worried about that if there is actual switch then why MOSFET acts as a switch in curcuits.
Forgive me for stupid question.

In cases where electronic logic circuit switching takes place, then it is often more efficient to do this with a semiconductor device, rather than a physical contact of some kind..
The final application and nature of design decides it.

Semiconductor devices can switch faster than mechanical switches, don't have contacts that can bounce, and don't wear out mechanically.

MOSFETs can be used as more than switches.
