1N4007 Diode

2200µF Electrolytic Capacitor

BC547B NPN Transistor

When the switch in the _ _ circuit is on ths circuit is on and charge Capacitor is on ths circuit is on and works when we stop switch works the voltage an Capacitor is turn on the transistor the delay time of the circuit is the capacitor valuo and Sorry for my English language
