Whale Electric Field Bilge Switch With Time Delay

The Whale Electric Field Bilge Switch With Time Delay (Model BE9006) is a marine-grade automatic bilge pump activation system designed to protect your vessel from water accumulation with minimal operator intervention. This field-effect switch eliminates the need for mechanical float mechanisms, replacing them with solid-state sensing technology that detects water presence and triggers your bilge pump automatically—ideal for cruising boats, fishing vessels, and any watercraft operating in conditions where consistent bilge monitoring isn't practical.

The time-delay feature prevents nuisance pump cycling caused by minor water movement or wave action, a common frustration with standard float switches. The unit mounts easily on horizontal or vertical surfaces—bulkhead, hull, or bilge compartment—and operates without toxic mercury, making it both environmentally responsible and compliant with modern marine safety standards. The field-effect sensing approach offers superior reliability in salt-air environments where corrosion and mechanical wear compromise traditional switches over time. Engineered by Whale Marine, a manufacturer with established credentials in marine fluid systems, this switch is built to integrate seamlessly with Whale bilge pumps for a cohesive, dependable bilge management system.

This switch suits boat owners and operators who want reliable, automatic water removal without the maintenance burden of float-based systems. Weekend fishermen benefit from the set-and-forget operation during extended trips; serious offshore anglers appreciate the reduced intervention during heavy-weather conditions when manual bilge monitoring becomes impractical. It's particularly valuable for vessels in storage or seasonal use, where water accumulation can occur unattended. The compact form factor (5 × 2 × 7 inches) fits tight bilge spaces without requiring extensive modification, and the time-delay logic reduces power draw and pump wear compared to rapid on-off cycling.
