Sea-Dog Compact Battery Switch 422761-1, On/Off, 48V 300A, 3/8 Inch Stud

The Sea-Dog Compact Battery Switch 422761-1 is an On/Off battery disconnect switch built to isolate a single battery from its load group aboard a boat. It is rated for 48 volts and 300 amps, making it suitable for cutting power to onboard electrical systems when the boat is not in use, which helps prevent parasitic battery drain and protects the electrical system during storage or servicing. The switch is constructed of injection molded nylon with machined brass contacts for durable, corrosion-resistant switching, and it is ignition protected, making it safe for installation on gasoline powered boats.

This compact design measures 2-3/4 inches by 2-3/4 inches by 3 inches and can be installed either as a surface mount or a rear panel mount, giving flexibility for different helm or engine compartment layouts. The stud diameter is 3/8 inch to accept common battery cable terminals. Installation requires four #10 RH fasteners, which are not included and must be sourced separately. This On/Off switch is a single-battery, single-load-group disconnect and does not include the Both/1/2 selector functions found on other Sea-Dog battery switches.
