Sea Sense Illuminated Switch On/Off/On

The Sea Sense Illuminated Switch On/Off/On is a sealed marine electrical switch designed for boats, RVs, and other applications where reliable, weatherproof control is non-negotiable. Built for 12V systems, this switch combines a three-position design (on, off, on) with an illuminated indicator, making it easy to locate and operate in low-light conditions—whether you're managing cabin lighting at dusk or toggling essential systems in challenging weather. The sealed front panel keeps dust, spray, and moisture away from internal contacts, a critical feature in saltwater and spray-prone environments.

Sea Sense marine electrical products are engineered for the harsh realities of boating and overlanding: vibration, shock, moisture, and salt spray resistance aren't nice-to-haves—they're baseline durability. This switch won't corrode or fail when exposed to the elements, and its solid construction handles the constant movement and jarring typical of marine vessels and rough terrain.

If you're rewiring a boat's electrical system, upgrading lighting circuits, or building out an expedition rig's power management, a reliable sealed switch with illumination eliminates fumbling for controls in dim cabins or tight spaces. Pair it with other quality marine-grade components to ensure your electrical system performs when conditions get wet and wild.

Frequently Asked Questions

Will this switch work in saltwater marine environments?

Yes. The Sea Sense Illuminated Switch is specifically salt spray resistant and sealed against moisture, making it suitable for boats and coastal applications where corrosion is a constant threat.

Is this switch suitable for boat rewiring or marine electrical upgrades?

Yes. It's designed for 12V marine electrical systems and built to handle the vibration, shock, and spray exposure typical of boat environments. The sealed, illuminated design makes it practical for cabin lighting and system control.

What does the On/Off/On configuration do?

The three-position design allows the switch to power two different circuits or operate in a momentary-on configuration—common for marine applications like dual engine controls or dedicated shore power circuits. Consult your electrical system documentation to confirm the specific function for your installation.

Can I use this in an overlanding or expedition rig?

Yes. The vibration and shock resistance makes it well-suited to vehicle electrical systems, and the sealed design protects against dust and moisture in off-road and remote conditions.
