I recently killed my UDB after not heeding the warnings about putting them
on mechanical switches.
Instead of just replacing the fuse with another fuse, we found it a better
solution to replace the fuse with a 10ohm, 1/4A resistor. No more fuses to
blow and it seems to work fine on mechanical keyboard switches now. (It was
"better" in my case since we didn't have any fuses of the original type to
replace it with.)
