Delay timer transistor circuit diagram - 230 AC delay off timer circuit

This is a very simple delay timer single transistor 230v circuit. One time press the bush button this timer circuit off after little time. you can change capacitor value and you can adjust timer off time.
This is 230 AC circuit, Dangers of electricity, Electric shock and burns from live wire contact. be careful.

Super bro..

Thanks

bro, can I make a switch using an NPN transistor, but without using a relay box like that. because only for my ne555 pwm activation and deactivation. can I put this npn transistor on the pin nno 1 of the ne555 which serves as the ground of the ic.

yes you can. what is the power consumption of your load. I think better to use IRF 44 FET Transistor
