<description>&lt;h3&gt;SparkFun Electronics' preferred foot prints&lt;/h3&gt;
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.

In this library you'll find submitted parts from SparkFun users everywhere!&lt;br&gt;&lt;br&gt;
These are not necessarily parts we carry, but are parts that other users have determined function well with other parts in our libraries. Please keep in mind that it is the end user's responsibility to ensure correctness and suitablity for a given componet or application.
&lt;br&gt;&lt;br&gt;
If you find these parts useful, please consider helping the open-source community by contributing your own through GitHub. https://github.com/sparkfun/SparkFun-Eagle-Libraries
