In this library you'll find anything that moves- switches, relays, buttons, potentiometers. Also, anything that goes on a board but isn't electrical in nature- screws, standoffs, etc.&lt;br&gt;&lt;br&gt;
We've spent an enormous amount of time creating and checking these footprints and parts, but it is the end user's responsibility to ensure correctness and suitablity for a given componet or application. If you enjoy using this library, please buy one of our products at www.sparkfun.com.
