Sparking-with slider as fan regulator
I have implemented the Capsense slider as a fan regulator; while doing that I have used capacitors to control the fans speed.
The problem I am facing is While 1st 3 (1=C1, 2=C2, 3=C1||C2) stages work fine (no spark in relay); but @ final stage when no capacitor is implemented there is a Spark inside the relay employed to run the fan @ max. speed.
Why would it happen? what should I do to correct it? Do I need to add another small Capacitor in parallel to final stage as the load driven is Inductive?
Thanks & Regards-
