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.

Step 1: Get the stuff
1 3v Button cell (CR2032 works well)
1 momentary switch (I used a lever swich)
1 3 inch lenghth of wire (stripped at the ends 1/4 inch)
