Automatically switching OFF AC power supply:
i require a circuit that can automatically switch off AC power supply after time period of about 20 sec. ( switched ON manually; circuit has to switch OFF automatically
 

do you want the circuit to hod its state (or latch on ) after the on delay?
if yes then this is the circuit.

else
you can attach a flip flop to the o/p
