I bought a homemade 3D printer and the cable was simply screwed to the terminal. So I looked for a switch and found one that also has a fuse. A very nice addition to security. I like that the switch cuts both live and neutral lines. There is no product diagram. This is what you see. The graphic in the product description is helpful. If you look closely you will find (E) Earth, (N) Neutral and (L) Alive. Live stream goes straight to backup. The supplied terminal is shown in the figure. Light blue is heat shrink tubing. I don't like that the other connectors aren't covered, but it's easy to heat shrink tubing to protect them.
