Hello,
I am working on a Hydrogen fuel cell car project that requires me to have an emergency shutoff switch on the outside of my vehicle. The problem is that the Fuel cell has a button that need to be depressed for 5 seconds to turn off. I need to figure out how i can use a momentary switch o the outside of the vehicle so that it can be pressed once and once hit activate the off circuit for the 5 seconds necessary to shut down the fuel cell.
