I suggested to Miroslav that an easy way to get this sort of value into EPICS would be to buy a cheap USB mouse and wire the switch across one of the mouse buttons.  I've put together a small example showing how to read from a USB mouse into an EPICS PV.   It's very basic, but it does seem to work.  If anyone's interested I will e-mail the support module and example application to try out.   
I've tested this only on OS X, but it should work on any system that supports libusb-1.0.
