We used an Ontrak USB Relay box in a recent exhibit... their somewhat 
mind-numbing product page is here:

http://www.ontrak.net/products.htm

We're using it exclusively in the opposite direction -- we wanted the 
computer to control switches, not switches to control the computer! 
-- so I can't vouch for it as an input device.  It works fine for our 
needs, though.

Ontrak also doesn't advertise MacOS compatibility (although I'm sure 
a competent hacker could get it working); I'm happy to see that 
Lath's suggestion does.
