Yes sir I confirm requirements for my above mentioned post...Threshold is 40 -60 millivolt ac. and maximum voltage applied will be 18 V ac.However if circuit is a bit flexible for threshold setting to a some greater value for future it would be an added point.(max upto which it can be easily done ),but its just an added point..not requirement at this stage.
For current stage My requirements are final as i stated in my last post.
Lastly yes circuit current is within safe limits and supplied by neon and resistor..
Best Regards sir
@amad1
You almost confirmed...:) So...what will be the maximum threshold that you will ever need?

Around 70 volt ac? If possible keeping in view minimum threshold lso...But if it is possible at this stage...
If its difficult then we can work for 18Vac ....
Best regards sir
