How To Prevent Relay Contacts From Sticking. You need to add a snubber across the relay contacts, or install a new relay, hopefully with better contacts. Note that this is not contact welding caused by long duration. Also some types of corrosion can cause them to stick. When the pip and crater are sufficiently big, contact sticking can occur because of the extreme rough contact surfaces. When relay contacts open and close, small sparks called arcs can eventually cause them to stick together. Your relay contacts need a snubber and/or mov/tvs to suppress the inductive spike when switching an ac inductive load (your. An rc snubber is a series. I suspect this because i have seen precisely the behaviour that you're describing, down to the sharp tap on the relay body causing. Capacitors & induction motors can both have huge initial inrush surge current transients that are often too short in duration to accurately show on most ammeters. It seems like the arcing could cause some carbon on the contacts, which might stick until the relay is tapped.
