Simple LED Switchie

Intro: Simple LED Switchie

Ok, let's make an LED Switchie!
(this is based off LED throwies from grafitti research lab)

You need:
A pair of scissors
A 3 volt lithium battery (CR2032)
Electrical (or other) tape
About 1 inch plastic piece

Step 1: Step One

First off, insert the battery into the two pins of the LED.
Positive is the longer one and negative the shorter one.
What is seen on the image should happen.

Step 2: Step Two

Insert the plastic piece between the anode (longer pin) and battery.
It will create a division, so, pressing on the two pins should make the LED light up.

Step 3: Final Step

Cut a piece of tape and wrap it around the assembly.

You just made a quick emergency LED Switchie!

    you can also use cr 2025, the only difference between cr2032 and cr2025 is that cr2025 is thinner and has a capacity of 160 mAh and cr2032 has 220 mAh
