...wearing full body armor did it! Or it could have been done quickly by
someone with strong will like Glorfindel. Recall that Faramir is able to
withstand it better than Boromir. So it stands to reason that very brief
contact might not have hurt them. After all, the hobbits have been able
to hold onto it without immediately becoming possessed. The Ring seems to
affect each individual differently, and some are better able to handle it than
others.
Elrond did very deliberately avoid contact with it, but he has a longstanding
history with the Ring! The Elven ringbearers might be more vulnerable as
Galadriel's temptation and Gandalf's fear of it
suggest.
