The switch activates the connected bilge pump when water in the bilge reaches 2 inches and turns the pump off once the level falls to 3\/4 inch, keeping the bilge compartment clear without manual intervention.\u003c\/p\u003e\u003cp\u003eThe Super Switch is fitted with a larger float than Rule's standard float switches for increased buoyancy and more reliable actuation, along with a detachable mounting base that allows the switch to be removed for cleaning or servicing without disturbing the wiring. Exclusive moisture-tight seals and 14 AWG, highly abrasion-resistant marine-grade blocked wire (28 inches long) protect the internal switch mechanism from bilge water and prevent corrosion at the wire connections. The switch is entirely mercury-free and backed by a 5 year warranty.\u003c\/p\u003e\u003cp\u003eThe Rule Super Switch 37A supports 12, 24, or 32 volt DC systems, with amp draw ratings of 20 amps at 12V, 10 amps at 24V, and 6.5 amps at 32V, making it suitable for a wide range of submersible bilge pumps on boats and other marine vessels.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
