Sorry for the confusion.  It is a mechanical switch on the pedal arm 
not a pressure switch on the master cylinder.  The mechanical switches 
on the pedal are pretty much industry standard now.  Much faster acting 
and more reliable.  They are a normally open switch that closes with 
the slightest movement of the pedal if adjusted properly.    The 
uninstalled ones are actually self adjusting during assembly.  Install 
it, depress the pedal, and it has a ratcheting feature built in that 
sets the switch to that particular car's tolerance stack up of parts.  
Pretty neat switches.
