Dear Singh,

As you advised, I have connected PNP transistor and see the below changes observed

1)LED is glowing when the power is ON

2)LED getting off after few seconds and getting ON automatically even I do not press switch

3)While pressing the switch also, the LED is glowing and gets off after few minutes

Since it is getting ON and OFF automatically (even if I don't press switch), I have connecetd Diode between pin 11 and 1 (instead of 2 and 11), Now the LED is getting ON while I power ON but after few seconds it gets off and it is getting ON while I press switch and gets off after a period. Now the problem I face is , while power on first time, the LED gets ON for few seconds.

Please advise, what to do….Is it right, if I connect diode between pins 11 and 1?

Regards,

Shine
