Sea-Dog Heavy Duty 600A On Off Battery Switch

This Sea-Dog Heavy Duty selector switch, model 422768, delivers 350A continuous and 1,500A cranking amps, enough to start a dual diesel engine setup. It isolates and/or combines two battery banks as needed.

It installs with four #10 RH fasteners, which aren't included, so it's worth having those on hand before starting the install. It can be surface or rear panel mounted depending on the layout.

It's ignition protected and safe for installation on gasoline-powered boats. It's built from injection molded nylon with machined brass contacts for durability in a marine environment. Shop more battery management systems.
