Whale Electric Field Bilge Switch With Time Delay

The Whale Electric Field Bilge Switch With Time Delay is an essential automatic water management system for serious boaters and marine enthusiasts. Whether you're running a cruiser, fishing vessel, or auxiliary sailboat, unwanted bilge accumulation can compromise hull integrity and create safety hazards. This intelligent switch eliminates the need for manual monitoring by automatically detecting water ingress and activating your bilge pump before problems escalate.

Built by Whale Marine—a trusted name in marine engineering for decades—this switch provides reliable, hands-free protection during extended time away from the helm. The electric field sensing technology works without moving parts, eliminating false triggers caused by slosh, vibration, or foam that plague traditional mechanical float switches. The integrated time-delay function prevents nuisance pump cycles from minor water sloshing, activating the pump only when sustained water presence is detected—extending pump life and reducing battery drain on auxiliary systems.

This solid-state design is sealed against corrosion and saltwater intrusion, critical factors in marine environments where galvanic corrosion can disable equipment in months. The switch mounts cleanly in tight bilge spaces and connects to 12V or 24V DC bilge pump systems with simple two-wire installation. Cruising boaters, liveaboards, and fishing captains who leave their vessels unattended benefit most from this automated solution—peace of mind while you are away.
