MSD window switch w/ 2 stages N2O

Instigator

POHO's finest Redneck!
can i use 1 MSD window switch for both stages or do i need 2 window switch's ?
thanks in advance!! scott
 
im using 1 for safety so if something breaks it dont free rev it on the N2O ,it will shut the N2O off at the rpm i set it at

the window switch is alot cheaper then a motor ....LOL

I use a timing tuner(ls1 parts) for the first stage and a window switch for the second. fuel injected cars don't like it when you hit the rev limiter(fuel cutoff) while spraying
 
both stages won't come on at the same time if you use the window switch to power the micro switch and a button before the relays. Dave
