[this is copied from another post...to help field some Q&A]

am going to run a WOT switch for safety so the nitrous isnt activated at anything under full throttle.

now i had been debating between a push button activation or a window switch....but i dont think im understanding the window switch. i realize it creates a "window" for the juice to be used...ex. 3000-6000 rpms....BUT will the window switch automatically spray the nitrous from 3000-6000 or do you still have to push and hold the button? if so what is the use of a switch if you stil have to push the button?

also i heard you can program the window switch to activate at a certain gearing (auto car) but everything i have seen listed in the parts description doesnt mention anything about it.
