When it comes to float switches engineered specifically for marine bilge pump automation, Rule Industries has set the standard for over five decades. Since 1965, Rule has been a trusted name in marine solutions, and their float switch lineup reflects the same commitment to durability and reliability that made their bilge pumps an industry benchmark.
The Rule-A-Matic Legacy
The Rule-A-Matic Float Switch is the go-to choice for boaters worldwide, with the newest generation featuring mercury free silver tin oxide contacts tested to over one million cycles. This flagship product line demonstrates Rule's engineering focus on creating switches that activate reliably in harsh marine conditions. The float switch activates the bilge pump when the water level reaches 2 inches, and turns the pump off when the water levels falls to 3/4 inch, providing precise control that prevents both pump dry-running and excessive water accumulation.
The detachable mounting base makes the switch easier to install and remove for cleaning, addressing a common frustration in bilge maintenance. Compatible with bilge pumps that draw up to 20A and featuring 14-gauge, abrasion-resistant, marine-grade wire, these switches are built to handle the electrical demands of commercial and recreational marine applications without compromising safety or performance.
Advanced Float Switch Technology
Rule's commitment to innovation extends beyond their standard offerings. The SuperSwitch features a larger float that increases the buoyancy and makes the switch quicker to respond to changes in water levels in the bilge with less ON/OFF cycling. This design reduces wear on both the switch and the pump motor, extending system lifespan in vessels that experience frequent water ingress.
The rugged float switch features a strong, fully-integrated, impact-resistant cover that keeps out debris to prevent jamming, and an external lever allows the float to be manually lifted to periodically test operation. These practical engineering touches reflect Rule's understanding of real-world marine environments where debris, oil, and sediment can compromise inferior switches.
Why Marine Professionals Choose Rule Float Switches
Rule Industries' position as part of Xylem's water technology portfolio ensures ongoing investment in marine pump technology research and development. The mercury-free snap switch design includes marine grade blocked wire, meeting modern environmental standards without sacrificing the reliability that commercial fishermen and liveaboard cruisers demand. The Rule-A-Matic Plus model expands compatibility to 12V, 24V, and 32V systems, making these switches adaptable to virtually any vessel's electrical configuration.
Whether you're retrofitting an older bilge pump system or specifying components for a new installation, Rule Industries float switches deliver the proven performance that has made them the default choice in marine automatic pump control for generations of boaters.
