Sea-Dog Battery Selector Switch 422760-1, Off/1/Both/2, 48V 300A, Nylon/Brass

The Sea-Dog 422760-1 is a four-position battery disconnect and selector switch built to isolate or combine two battery banks aboard a boat. Turning the knob through Off, 1, Both, and 2 lets the operator run off a single battery, combine both banks for extra reserve, or shut the electrical system down completely for storage or service. The switch is rated 48 volts DC at 300 amps, with 3/8 inch diameter studs for heavy-gauge cable connections.

Construction is injection molded nylon for the housing with machined brass contacts at the switching points, giving corrosion resistance along with a low-resistance current path. The switch is ignition protected and rated safe for installation on gasoline powered boats. It can be mounted on the surface of a panel or from behind a panel for a flush look, and it installs with four #10 RH fasteners (not included).
