'[EE] source for small/flat jumpers?'

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
