Toggle Switch 12/24V – 20A – 6.3mm Terminals – Waterproof IP67 - Bipolar

Marine-Grade IP67 Bipolar Toggle Switch – 6.3mm Fast-Connect Terminals | TRIREME

This bipolar toggle switch is designed for full circuit isolation, making it ideal for metal-hull boats (aluminum & steel) where galvanic corrosion prevention is critical. Featuring 6.3mm fast-connect terminals, it ensures quick and secure installation while maintaining a reliable electrical connection in demanding environments.

The stainless steel (INOX316) toggle provides maximum corrosion resistance, essential for harsh marine and industrial conditions, while the zinc alloy core housing enhances mechanical durability for long-lasting performance.

Bipolar Contact Configuration – 2NO2NC (2 Normally Open, 2 Normally Closed)

This bipolar DPDT switch isolates both positive and negative circuits, preventing stray currents that can lead to electrolysis and galvanic corrosion, especially on aluminum and steel hulls. The 2NO2NC configuration offers flexible switching options, making it ideal for marine, automotive, and industrial applications where precise control and circuit isolation are required.

High Current Rating for Marine & Industrial Use

✔️ 24V DC – 20A
✔️ 12V DC – 40A

Designed for high-power systems, this switch can handle heavy loads in 12V and 24V electrical networks, making it a reliable choice for battery management, lighting, pumps, and high-draw equipment.

Depending on whether you are using a 4-wire or 6-wire configuration, the wiring method will slightly differ.

💡 Perfect for:
✔️ Aluminum & Steel Boats – Prevents corrosion and electrical leaks.
✔️ Shore Power & AC Circuits – Ensures safe disconnection of both poles.
✔️ Marine Electrical Panels – Reliable operation in wet and salty environments.
✔️ Battery and Lighting Control – Supports independent circuit isolation.
✔️ Heavy-Duty 12V/24V Systems – Handles high currents for demanding applications.

This heavy-duty marine toggle switch provides superior protection, full electrical isolation, and high durability, making it an essential component for any advanced marine electrical system. ⚓🔧
