    Hello all,

    I have a project I would like to do, and I think it should be fairly simple to accomplish, but my googling has not led me to an answer. Basically I want to develop a switch that will pulse.

    Here is the basic operation:

    A simple momentary button will activate it
    when this button is NOT pressed, the switch will simply be a normally closed circuit
    When the user presses and holds the button, the switch will pulse open until the user releases the button.
    This pulse will be adjustable.

    For example, the circuit is closed and working normally, the user holds the button, the switch goes open for .001 second, then closed for .100 second, open for .001 second... etc. then the user releases the button and the switch goes closed completely again.

    Any help would be great!

    Doable. What voltage and current have to be switched? Volts, amps, AC, DC??

    Sounds like a fun project.

    Why is it that the purpose of projects, always seems to be secret?:confused:
    Giving the intended use, will elicit the most useful ideas.:)

    Sounds not to be a line powered device, with micro second timing!
    Also leaves relays out.

    Thanks for the replies everyone. Basically this will be used for only 12V DC. May be up to 13 or 14V at some times since it is on a car. Also, it will see no more than 30 amps.

    Here is what I am "trying" to make, just so you have an idea.

    Perfectly doable project until you said the "car" word.

    Sorry, read the Terms of Service and you will learn that discussion of automotive modifications is not allowed on AAC.

    There are other forums than can help you.
