Shurflo by Pentair Caged Automatic Float Switch - 12/24 VDC

The Shurflo by Pentair Caged Automatic Float Switch (12/24 VDC) is the dependable bilge control solution serious boaters rely on when water management matters. Whether you're running a cabin cruiser, fishing vessel, or sailboat for extended periods, automatic float switches eliminate the guesswork and manual monitoring that drains batteries and attention from what counts—being on the water. This marine-grade unit handles the dual-voltage electrical standard found across most recreational and commercial marine applications, making it a universal fit for vessels ranging from small center consoles to larger displacement hulls.

Built with a cage-design float mechanism and non-mercury construction, this switch activates bilge pumps automatically when water levels rise, then deactivates them when the bilge drains—all without moving parts that corrode or fail. The 3-foot tinned wire assembly resists salt spray and galvanic degradation, critical advantages in saltwater and brackish environments where standard copper wiring oxidizes rapidly. Ignition protection and remote or direct mounting flexibility mean installation works whether your bilge pump controller sits inches or feet away from the actual float location, adapting to tight engine compartments and unconventional layouts that plague retrofit jobs.

Anglers and cruising boaters benefit most from this switch's set-and-forget reliability during overnight anchorages, multi-day offshore runs, and situations where engine-driven bilge pumps aren't continuously available. Backup power systems, live-aboard setups, and vessels that sit idle for weeks depend on automatic float switches to prevent water accumulation and structural damage. The Shurflo by Pentair 12/24 VDC model's three-year warranty and marine-industry reputation make it the logical choice for owners who refuse to compromise on bilge management—because losing a boat to preventable water intrusion is never an option.
