Hi Don,

When I acquired an SB-220 a few years ago, it has several burned 
contacts.  After looking unsuccessfully for a replacement at a reasonable 
cost, I went the repair route.

At a hamfest, I found some switches with nice gold plated contacts for 
about a dollar per switch.  I drilled out the rivits holding the 
contacts, and fitted them to the damaged switch (I replaced them in 
pairs--one on each side of the wafer).  To hold the new contacts in 
place, I cut a piece of thick copper wire, and inserted it through the 
rivit holes and through the switch wafer.  I then soldered the contacts 
into place against the shaft of the copper wire.

Obviously, this is delecate work; but if you're so inclined, you can make 
the switch as good as new.

Good luck,
Dan - W4TQ
