    I am having troubles trying to figure out how to build this circuit. I have been searching around the net trying to find a similar circuit but no luck.
    What I'm trying to do is build a circuit so when I apply 12v to circuit it waits for about 5-10 seconds before it changes state of the "contacts" for about 1 sec then stops until the next time the 12v source is applied.

    So in a nutshell. I want to make a 12v circuit for my car. I want the 12v line to this circuit to be a part of the "ACC" of the ignition switch. I want to make sure the car has started and will not be switched of right away. Hence the 5-10 sec delay before triggering the momentary contacts.

    Hopefully I explained that enough. I think it can get confusing so if I can help explain more please let me know..

    Thanks for your help.
