Good idea.
Simple but usefull....👍

If we want to change delay_duration, which one should replace.... resistor or capasitor?

Used a 2n3904 and switched it around to work right (is opposite than bc547). Used a 9v source and fucker blew its lid... thought 2n3904 handled bigger loads than bc... but your circuit is not right, i had to run wire from switch to pin connecting npn to relay..
