 		 #111975 - not for my use

Kai Klaas said:

Why are you so focused on using a relay for the swicthing? A relay would only consume additional supply current, while the MOSFET or constant current source would not waste anything relevant.


not for my use.
I think its intended to be given to a customer for a lamp load application.
so, just checking for its life after inrush is being controlled.
