Heavy-Duty Float Switch for Bilge Pump 12/24/32V, 20A

This 20A heavy-duty float switch is a top-of-the-line model engineered to tackle the most demanding bilge pumping tasks. With its ability to operate on 12V, 24V, or 32V, it covers the full range from small boats to large ships. Its 20-amp switching capacity means it can directly control very powerful pumps, including 2000 GPH, 3000 GPH and above, without the need for an extra relay or contactor. This simplifies the system and reduces potential failure points.

The float’s construction is reinforced: made with high-grade materials – a housing of thick ABS/polycarbonate blend for impact resistance, and seals that ensure the switching mechanism remains watertight. The internal contacts are designed to switch high current with minimal arcing, extending their lifespan. All metal components (if any are exposed) are stainless steel or similarly non-corroding metals to withstand saltwater conditions.

Intended Use:

• Large yachts and ships: Vessels over ~40–50 feet often have high-capacity bilge pumps (or multiple pumps) installed. This float switch is capable of controlling them reliably. For instance, if you have a 3700 GPH pump on 24V (which might draw around 15+ amps), this switch will handle it with ease – and it will do so on any of the supported voltages.
• Commercial applications: Fishing trawlers, work barges, rescue boats – all can face extreme situations where water is pouring in rapidly. Here, response speed and reliability are critical. The heavy-duty float will endure continuous cycling, pounding waves, vibration, and debris far longer than standard models, maintaining its function when it’s needed most.
• Dual pump systems: Some yachts employ two pumps – a primary and a backup set to kick in at a higher level as an emergency measure. This switch can handle such a high current that it even allows (with proper wiring) simultaneous activation of more than one pump when a critical level is reached. For example, your main pump runs off one float, and this heavy-duty float triggers an additional pump (or both at once) if water rises further.
• Maximum security: If you want the absolute best in flood prevention for your boat, this float provides exactly that – maximum reliability headroom. Even if your pump is smaller, using a switch with a higher capacity means it’s under less strain and will last even more cycles.

In summary, the 20A heavy-duty float switch is a professional-grade solution for automatic bilge pump control. It brings industrial toughness to your vessel’s dewatering system. With this switch, you can be confident that even your most powerful pump will be commanded exactly when needed, without fear of the switch burning out. It’s reliability you can count on in critical moments, keeping your vessel dry and safe.
