    Hi guys, I need some help.

    Project:
    LED connected to a AA battery with a single push on/off metal dome switch.

    Question
    How would I connect the dome switch so that push once = On, push again = off?

    So its a bit like pressing the on/off button on a calculator. Just that I don't understand or know what components I'd need. Some kind of Chip? Relay?


    Cheers! Mike.

    See a few examples of a on/off switch.

    Cheers for the diagrams, I wish I could pretend I knew what I was looking at :):), I've never actually made a circuit with the aid of a diagram then again never made anything more complex than a simple motor,battery,light circuit.

    I ripped apart a old Panic alarm/LED Flashlight and managed to make a circuit with the metal dome switch. Working great. But it means the light doesn't illuminate constant....so to make my life simpler as (shortbus suggests) I'll use a normal switch.
