    I just need a website to order a tiny click on, click off type switch. It will be mounted in a ring so it has to be super tiny.
    Anyone know where I can find something like that?

    Sir Jbatts39 . . . . .
    Not knowing the mounting relationship position on the "ring" nor its size, how much BIGGER can the switch be, than the one being shown ?

    Well that one would be great but I would say no bigger than 3mm

    How do you work that switch?! Trained ants?

    What battery will you use?

    I think I would need more information to help find a switch. How do you want to mount this switch. When you say 3mm is that a 3x3x3mm max overall size? What are you powering/controlling?

    I'm using a button cell. It's powering 1 led. I will carve out a spot on the side of rhe ring and glue it in place.

    Don't forget a current-limiting series resistor.

    I hopefully won't need one. Planning to match up the battery and led voltage.

    I think most leds can handle 3v just fine anyways. Provided the button cell you are using is a 3v cell

    I think you will find the practice of running an led off a coil cell without a resistor is more to do with the cell internal resistance and ability to only provide the small current. Installation of the coil cell on a ring will be rather ratty though even with a miniature switch.
