HELLO SIR,
I WANT TO GET ONLY 6V OUTPUT. I WANT TO SWITCH ON SOME DC DEVICES.I DONT WANT TO TO FIX THIS CIRCUIT TO APPLIANCES.CAN YOU TELL WHERE TO CONNECT DC DEVICES.

THANKS

HI Raghu! I understand your problem. It happens only when you turn on and off your circuit very fast. It happens because the capacitor contains some charge stored even you turn off and it takes sometime to discharge completely. So, if it is large delay when switching the circuit, the problem cannot be seen.

this circuit is working fine but i have a small problem with this circuit..i have connected a ac motor as a load to the circuit and it is working perfectly ..but my problem is .. the circuit toggles state as soon as it is switched on .. i.e., if the motor is in running state when the power is switched off.. once the power resumes the motor will be in stop .. and vice versa.. i want the motor to be in off state irrespective of its state before it loses power…..

Hi Arifuddin Sheik a nice blog. Your circuit 2 is quite simple. you have explained about the above circuit also nicely. yes NE555 is added for positive fail safe switching. your idea of using delay with acapacitor without the use of NE555 is also good. keep it up. thanks for your comments. readers can visit his blog on the following address. useful informations.

i have posted similar circuit which can be used to control home appliances. But it does not need the 555 timer. Using 100uF across the TSOP output is just enough to create a 1 sec delay. I have also designed TV Remote circuit which can control 8 devices using single receiver by using 1-8 remote keys. Check out my blog
