Description
Whale Electric Field Bilge Switch | Boat Supply Store
This automatic switch ensures your bilge remains dry by detecting the presence of water without mechanical contact. It operates reliably in corrosive marine environments, triggering your bilge pump when water levels exceed 1 inch (25mm). Ideal for offshore vessels operating in the Gulf of Mexico where consistent water management is critical.

Common Concerns Answered
How does this switch prevent false activations from wave slosh?
The electric field sensing technology has a built-in delay that requires a sustained water level to activate, preventing false triggers from minor wave action.
Is the switch susceptible to damage from oil or debris in the bilge?
The solid-state design is resistant to common bilge contaminants like oil and minor debris, ensuring consistent performance unlike mechanical switches.
What happens if the switch itself fails?
While designed for extreme durability, it is recommended to regularly test your bilge pump system. The lack of moving parts significantly reduces failure points compared to traditional float switches.
Frequently Asked Questions
What is the minimum water level required to activate the pump?
The switch activates when the water level reaches 1 inch (25mm) above the switch base.
Can this switch be used with any bilge pump?
Yes, it is compatible with any standard 12V or 24V DC bilge pump up to 20A.
How many amps can this switch handle?
The switch is rated to handle up to 20 amps, which covers most common bilge pump requirements.
What are the physical dimensions of the switch?
The switch measures 4.1 inches in length, 2.8 inches in width, and 2.0 inches in height.
Is a separate control panel required for operation?
No, this is a standalone automatic switch that directly controls the bilge pump based on water level detection.
