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!

Step 1: Get the Stuff

You need:
1 LED
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)
Electrical tape
Scissors

Step 2: The Circut Diagram

A very siimple circut

Step 3: Build the Circut

Tape the Annode of the LED to the positive (+) terminal of the battery. (See pictures1-2) connect the cathode of the LED to the positive (+) terminal of the SWITCH. (See pictures 2-3) connect the negitive (-) terminal of the SWITCH to the negative (-) terminal of the BATTERY. Test the circut by pressing the lever (or flipping the swich). The LED should light up.
