The term was Bi furcated - having two parallel contacts increases contact  
reliability significantly.  Particularly important in telephone  switches

LM Ericsson, Sweden (the old  telephone manufacturer) had a patent many 
years ago regarding double contacts  in relays. They showed that the 
reliability of a relay was major increased  when you had two relay contacts in 
parallel. I believe you still find a term  for this, just can't remember what.
