ok well  they say nothing is ever easy...I have hit another problem;

testing the  circuit with an LED works fine, but when I hook up my
actual 12v valve, it  must be causing interference or something because
pressing fire and the  circuit switches on, and stays on indefinitely,
hence the valve stays  open.

its either causing the circuit to continually re-trip, or  shorting it
somewhere causing a constant "on"

anyone have any ideas  how I might filter this?


what about the current draw? for a LED it's nothing, but a valve  might be 
too much, what about putting a relay in between and see how that  works?
