The Conflopulator is the simplest, definitely-not-solid-state way to reverse the polarity of the voltage applied to any DC load.
Conflopulation is my made-up name for the technique of using a single mechanical switch to simultaneously swap both leads of a motor. I'm far from the first to come up with it, and it's described frequently in basic electronics blogs and forums. Here's just one example: HOW TO: Wire a DPDT rocker switch for reversing polarity
This module is just a slightly nicer implementation of that idea. I tried to purchase a module like this for a previous project, but it turned out there was no such thing. Now there is!

Note: If you order this product "assembled" it will come fully populated except for the headers. There are lots of different combinations that make sense for headers (top, bottom, not at all?) depending on your application so it's best if I do not install them. Headers are always included, never soldered.
