    Well, you are not going to get momentary contact how you describe it needs to be without some other power. Either with caps or otherwise. There has to be some flow of power to make a switch open and close if you leave the trigger circuit closed.

    Oh, and by the way, the timer I put in my car is DC, but not made for a car. It's just a 12v dc Timer. C'mon man.

    What I don't Understand is if you put a selector or rotary switch on something to control ATX power and it doesn't snap back with a spring or something than what you'll be doing is going from | to / to turn it on, then back to | then / to turn it off. That doesn't make sense.

    To your first post: A typical ATX power supply has an always hot 3.3V line.

    Think about an on/off rotary switch on an old stereo. Turn it to the left and it's off. Turn it to the right and it's on. That's what I'm trying to replicate.

    Now that I think about it, I don't think this is going to work either. Let's say the computer is on and the user turns the switch to the off position. While the computer's going through the proper shutdown, if the user turns the switch back to the "ON" position, it's going to screw it all up.

    This is a barebones linux system, so I'll work on making it read-only so the user can just cut the power and be done with it. This motherboard also has an AT power supply connection.

    Well, the momentary is going to be a hard find as a rotory button. Guess you could always but an on/off switch and just pulse it manually yourself.

    If you wanna get out of it the easy way, set your motherboard bios to turn on after power loss. and then just cut the power to the pc. When you go back in, the pc will start.

    You just need a one-shot circuit. Use one of these.

    Maybe open up a large rotary switch, and throw the internals in the garbage...make a cam for the shaft, and use brass strips from the local hobby store to fab up a set of contacts. Have the contacts before the notch so when it is in the process of being turned it makes, and when it hits the cam it breaks.
