- Safety Certified: Ignition protected (SAE J1171) for safe installation in gasoline-powered engine compartments.

Ideal for yachts, bass boats, RVs, and heavy-duty trucks requiring reliable battery isolation and circuit protection.
Frequently Asked Questions
- Will this switch cause a spark in the engine compartment?
- No. This switch is Ignition Protected and meets SAE J1171 standards, meaning it is hermetically sealed to prevent any internal electrical sparks from igniting fuel vapors in the engine room.
- Can I use this for my dual outboard setup?
- Yes. This 4-position selector allows you to isolate either engine's battery, or use the 'Both' (1+2) setting to combine them for high-current emergency cranking if one bank is low.
- Is the mounting hardware included and is it rust-proof?
- The switch features integrated mounting holes for standard 4mm screws. While internal components are tin-plated copper for maximum resistance, we recommend using 316 stainless steel mounting screws to ensure zero rust in saltwater environments.
