Demonstration of Ups operation

This circuit is just a simple demonstration of how an uninterruptible power source works.

Since batteries that can be charged aren't available in EC... I've used actual DC voltage source instead.

Also rectifier and inverter blocks and static switches are avoided for simplicity by using actual DC source as main line power

In normal conditions the green LED indicates that the critical load (lamp here) is receiving power from the main line.
Flip the switch which would resemble a power outage as the main line would be cut off.
The critical load would be supplied power from the "battery" without any delay (well,theoretically)
The red led would indicate the user  that the load is running on battery voltage.

Okay im totally new at this but I am a natural at all… I have a serious question with boards.. Why all the unnecessary twists and turns ???

Unnecessary? There are other ways eg bjt's but component count is low.

@ghettocowboy Because engineers want to butt fuck your brain and make shit more complicated than needs to be

Wait, are you talking about PCBs that you find in electronics (like home stereos, computers, AM/FM cassette decks and such)?..
