Have you ever made a LED throwie? If you have you know that it will just keep on shining for ever and ever (Or until the batery dies) unless you add a switch. This instructable will show you how to make a LED throwie with a switch. You can use any kind of swich but I used a momentary lever switch. Let's begin!

be cool if it would turn on when it stuck to a metal building , just have to position the switch so the level is pressed when the magnet part is flush with the metal siding.
Howdy,
Question about the momentary lever switch. Do you have a part number? I don't know what to google to find these kind of switches. I'm an absolute newb to playing with LEDs and want to use this switch with small edge lit display.
Thanks!

Don't forget you need a magnet for a LED Throwie! That's the whole "Throwie" Part. So you can throw them onto buildings to light it up!

But it is a momentary switch so you have to be holding it for it to light up. also I live in Mississippi, USA, and there arent very many big buildings to thow them onto. and if you do the super strict cops would probably arrest you.
