The Rule 35A Float Switch is a high-capacity, automatic bilge pump control designed for boats, yachts, and small vessels. Capable of handling up to 35 amps, it provides reliable, hands-free operation, activating a connected bilge pump as water levels rise and shutting it off once the bilge is drained. The built-in strainer prevents debris from jamming the float, ensuring consistent performance, while the durable marine-grade construction guarantees long-lasting operation in harsh marine environments.

Description

The Rule 35A Float Switch is engineered to provide dependable automatic control for bilge pumps in boats and small vessels. Designed to operate at 12V or 24V DC systems, it can handle up to 35 amps, making it suitable for high-capacity bilge pumps. As water rises in the bilge, the internal float reaches a set level and sends a signal to the connected pump to activate, removing water efficiently without manual intervention.

Constructed from durable marine-grade materials, the 35A float switch is resistant to corrosion and designed to operate reliably in harsh marine environments. It features a compact design with floor mounting options, allowing for easy installation in a range of bilge configurations. Pre-stripped wires simplify integration into existing 12V or 24V electrical systems. A built-in strainer helps prevent debris from jamming the float, ensuring smooth and consistent operation.

The Rule 35A Float Switch is ideal for boat owners who require a high-capacity, reliable, and automatic bilge pump solution, offering peace of mind during both active use and when the vessel is unattended.
