The contact material of relays plays a big part here.  Contacts that are 
designed to switch  microvolt
level signals, do not handle power  well.  Conversely,  power contacts  
can build up  oxides  which
prevent receive signals getting through.  Some have advocated passing a 
small DC current through
the contacts to keep them clean.
