This project was born out of a need for buttons that can be used on a solderless breadboard. I used to solder wires onto a normal push button switch. Not only were they big and clunky, but they would always break as well. I then settled on this design and have never looked back.     The buttons are typical tactile buttons. These can be bought for 40 cents to a dollar. They can also be salvaged from just about any electronic device     I am using a typical .1' breakaway header. I got mine from SparkFun.com, although you can get them from just about anywhere. Following is a picture of these headers. Unfortunately, they do not come the way you will need them for this project. All it takes is a set of needle nose pliers to slide each header flush to the black casing, thus allowing them to stick out farther to make a good contact with the breadboard. The first picture contains the original headers on the left and the header after sliding the metal down into the casing on the right. The picture on the right is where I placed the pliers to get them to slide. They are not glued so with a little pressure they should slide right down.

The next picture is the underside of the board. basically, I just connect one side of the button to all three headers on one side, and the opposite contact of the button to the other three headers:

And here's what you end up with:

Now you can plug the buttons directly onto a solderless breadboard and integrate them into your next project.
