Product Details

Rule 35A Rule-A-Matic Float Switch – Dependable Marine Protection Year after year, the Rule-A-Matic 35A remains the preferred choice for yachtsmen, commercial fishermen, and boat builders worldwide. Engineered for simplicity and longevity, this switch automates your bilge system to ensure your vessel stays dry without the need for manual monitoring.

Key Features:

Proven Reliability: Equipped with a patent-pending snap-switch design that has been rigorously tested to exceed one million cycles, ensuring years of worry-free service.
Intelligent Design: The internal mechanism is specifically engineered to prevent “pump cycling”—the rapid turning on and off of the pump caused by water sloshing in the bilge.
Marine-Grade Construction: Built to withstand harsh saltwater environments, it uses abrasion-resistant, marine-grade blocked wiring that prevents water from travelling up the insulation to the electrical connections.
Easy Maintenance: The switch features a removable clip-on base, making it incredibly easy to snap out for cleaning debris or performing routine inspections without unscrewing the entire unit.
Mercury-Free: An environmentally friendly alternative to older styles, utilizing a mechanical switch rather than hazardous mercury.
