Review on Smseace Electromagnetic Automatically Protection Electronic by Jim Bethea

Seems to be very good. I've used them for a variety of tasks from disabling the laser power interrupt to controlling a small water pump. They seem to handle small inductive loads with ease. The contact resistance started at 33 mΩ and after 180 engine starts the contact resistance is still 33 mΩ. Let's see how the product behaves after a few months of operation.
