Well, it is actually dumb stupid. They are a simple rod with a T-Head on the front. When the engine is on fire, the lamps in the hangle lit up (usually) red. Then you cut the engine, close the fuel and if the fire does not go out you pull the handle.It will come out about aninch or two. But once it is pulled forward th actual switch behind it is opened. It can not be then pulled back into place to warn you that that engine is actually out of comission. If the fire goes out, the lamp in the handle goes dark.
In commercial areoplanes we have stuff like agent 1 discharge, and agent 2 discharge, rotate the handle, use supplementary switched, etc. depending on the type and manufacturer.
But this is a fighter jet. We like to keep things nice and simple :joystick:
Pull the rod, and then that will CLOSE the fire extinguish switch once it is FULLY out. (or just put in a momentary OFF switch behind the (usually square) bar, and be happy :D
