Can anyone point me to a source for small/flat (low-profile) jumpers,
like the ones used on hard drive controllers?

Thanks,
  Bill

Nope... those are 6mm high.  I want something around 2mm or less.  And the
matching pins.

Something closer to these

but not nearly so pricey.

Do these need to be user-changed, or are these something set once during
manufacturing.  If the latter, you can use solder jumpers.

I started experimenting with this idea a few years ago, and think I've got
the size and shape figured out pretty well now.  The jumper is a disk of
copper split up the middle with a gap and soldermask over the gap.  With the
right size disk and gap, it's very easy to switch the jumper between open
and closed with a soldering iron.  After putting a medium glob of solder on
the two pads, a swipe with the soldering iron one way bridges the gap and
the other way opens it.

I have attached the Eagle script for this jumper package exported from my
connectors library.
