Mounted this on my boat's battery panel and it feels like it could survive a hurricane. The removable knob is a great safety touch — nobody can accidentally crank the system on while I'm working on it. Crisp positive click when switching.
Solid construction and rated properly for my 48V system. The knob removal feature works as advertised. Only gripe is the terminals are a bit close together for thick 2/0 cable, so plan your routing carefully.
Clean disconnect, quality terminals, easy install.
