Disregard this thread. my question's obsolete

what it does: the button opens the hatch, then the timer waits 3 seconds and the hatch closes

it does precisely what i want it to do, but i don't understand why it works

wouldn't the signal follow A (the arrows i drew), opening the door, and then follow B, activating the timer, and then the timer shuts off after it counts to 3, and that's that? doesn't the signal die there? why does it interact with the door again shutting it, i don't have any wiring going to the door's direction to tell it to shut at the end of the signal's path

EDIT: turns out the button in A automatically shuts off after a couple seconds, that's why this worked. the timer had nothing to do with it. i don't know how to delete the thread so i changed the title
