A led is to be switched off.

A simple circuit is used to switch the led on/off with 9 v.

After the led is first switched on, the switch remains activated/
closed.

However, the led should turn off after a fixed time (even though the
switch remains activated/closed), without being turned on again.


That makes little reals sense to my mind but is perfectly technically
acheievable.

Why not use a momentary switch ?

You never heard of a ONE_SHOT ?

I have, ONE SHOT is all it takes to get you all
baffled.!
