Cruise control switch on clutch pedal

So I'm about to hook up launch control on my MS3 system. I was going to use the neutral safety switch but it is at the very end of the clutch pedal which isn't really ideal for flat shifting as I don't want to have to push the pedal that far. So I was eyeballing the cruise cancel switch as it is at the top of the pedal throw. The thing is, Megasquirt uses ground to enable launch control. So I would need that switch to turn ground on when the pedal is pressed and off when released. Does anyone know if pushing the pedal completes the circuit or kills it? I would pull the switch and see but it is raining its ass off out there so I figure I can gather a little intel first then tackle it.
