Description

Off/1/2/Both Battery Switch - Surface Mount - Red Designed for dual battery setups, this 1/2/Both selector switch gives you full control to route power from Battery 1, Battery 2, both, or neither. It’s ideal for managing power flow, setting up backup systems, and charging multiple battery banks— all from a single, intuitive control point.

Ignition-protected and safe for installation aboard gasoline-powered boats, this 1/2/Both switch is perfect for both marine and RV applications. The versatile case design supports surface, front panel, or rear panel mounting.

Engineered for performance, it includes 3/8″-16 tin-plated copper studs for maximum conductivity and corrosion resistance, accepting both 3/8″ and M10 ring terminals. The 7/8″ stud length allows connection of multiple cable terminals with ease.

Built to withstand harsh environments, the switch is made from non-corrosive marine-grade metals and molded in reinforced polycarbonate for added durability. Tactile knob textures let you confirm position by feel alone, and the switch includes both international ON/OFF legends and an ICON label set for quick circuit identification.

Specifications: Continuous Rating: 300 Amps DC Intermittent Rating: 500 Amps DC (5 min) Cranking Rating: 900 Amps DC (30 sec) Max Voltage: 32VDC Cable Size: 4/0 AWG

Electrical — frequently asked

What’s the difference between marine wire and regular wire?
Marine wire uses tinned (tin-coated) copper strands that resist the corrosion salt air causes, and it’s more finely stranded so it flexes with vibration without breaking. Standard automotive or household wire corrodes and fails much faster in a marine environment.
How do I size a fuse for a marine circuit?
Size the fuse to protect the wire, not just the device. Match the fuse rating to the wire gauge’s safe current capacity so the fuse blows before the wire overheats. When adding a new circuit, follow the wire manufacturer’s ampacity chart for the gauge and run length you’re using.
Do I need a battery switch on my boat?
A marine battery switch is strongly recommended. It lets you disconnect the battery for storage or service, isolate a failed battery, and — on multi-battery setups — choose which bank powers the boat. It’s a core safety and reliability component.
