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 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.

Step 4: Making it smaller

Picture of making it smaller
Fold it so that the LED is ontop of the battery. Fold the switch on top of that. Now tape the entire thing together to hold it together.
