- 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.

Hong Kong Based, 8 Years of Expertise
The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories. These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.
Supply Chain
Invested Factories in Mainland China
To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.

Our products are built to power your voyage, while our packaging is designed to protect the purity of the blue sea.
