Okay undercover
The Board and changeover switch are better than expected and work OKAY. The switch is sturdy and appears to be made in china. The box on the other hand could be more sturdy, the screws to close the box are only going into thin plastic posts and could snap of easily if too much force is applied. The 2 screws holding the rail are put in by the manufacturer are thread stripped and needed replacing. The only markings I could find are IP65 on the box lid. Otherwise no mention that these Boxes are Waterproof or that they comply with any electrical standard.
However, I mounted these boxes under cover and they should be fine.
