Cortron Keyboards -- US Navy Shock Test

[Hypersphere]

Has anyone here heard of Cortron keyboards? They apparently pass the "shock test" of the US Navy:

Their site also shows a Cortron aboard the International Space Station. I wonder what switches are used in these things?

There are always a few on eBay, the most rugged varieties are typically priced too high for my taste. You can get some in the $40 - $60 range if you keep an eye out.

HaaTa can tell you more about the switches they've used.
