Answer Posted / greg gertsch
It has been my understanding; Dry contacts when open do not
transfer any voltage or currant to the load side.
wet contacts have voltage on the load side but no currant
flow. Such as when a varistor is used as a bridge allowing
line voltage to cross over to the load side which minimizes
the arcing on contact points
