Purchased for a 48 volt 25 amp e bike project. The perfect switch protector I was looking for. I use it as a switch, and who would have thought that 48V would bend so much when connecting standard plugs. I could only imagine that the circuit is defective. Small enough to put anywhere. One thought is that the rubber caps only cover the strut and not the nut. So there is a risk of arcing. I think I'll put duct tape on at some point. It also has an M6 size for ring connectors.
