The Rule SuperSwitch® Float Switch (Model 37A) is a non-mercury float switch designed for automatic control of bilge pumps, aerators, and other marine equipment based on water level changes. This switch is essential for boaters who want to prevent unwanted bilge accumulation, which can compromise hull integrity and create safety hazards.
Built with a gravity-actuated float chamber, the Model 37A responds instantly to rising water levels, eliminating electrical threshold delays or false triggers. Its non-mercury construction ensures environmental safety and compliance with modern marine standards, while the sealed internal mechanism resists corrosion from saltwater and humidity.
Ideal for liveaboards, commercial operators, and cruising families, the Rule SuperSwitch® Float Switch provides automatic protection for vessels, especially when left unattended. It is designed for easy installation in tight bilge spaces, making it a practical choice for upgrading existing systems or replacing older switches.
