Sparkfun designed this board to give the user a very discrete button without any sharp edges (kinda useful when you're wearing the button). Button closes when you push it and opens when you release (momentary push button).

LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!
