The switch activates when water rises to 1-3\/4 inches and deactivates once the level falls back to 3\/4 inch, giving a reliable on\/off cycle that protects against nuisance running while still catching rising water early. It comes with a 3 foot tinned wire assembly suited to the corrosive marine environment, and it supports either remote or direct mounting depending on how your bilge compartment is laid out. The switch is ignition protected and built with non-mercury internals, and Shurflo recommends mounting it horizontally for the most consistent performance. Internally it uses a mechanical, normally-open contact design with screw terminal connections, rated for 12 amps at 12\/24 VDC, and it carries an IP66 ingress protection rating along with UL listing for use in wet bilge environments. It is backed by a 3 year manufacturer's warranty. This switch is intended to work alongside your existing bilge pump as the automatic trigger, not as a pump itself, and it is a straightforward retrofit or replacement for boat owners upgrading from a manual-only bilge setup.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Shurflo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 359-111-30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Float Switch (Automatic Bilge Pump Switch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12\/24 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Amps:\u003c\/strong\u003e 12.0A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivation Level (On):\u003c\/strong\u003e 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeactivation Level (Off):\u003c\/strong\u003e 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Assembly Length:\u003c\/strong\u003e 3 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Type:\u003c\/strong\u003e Tinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Remote or direct mounting, panel mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Mounting Orientation:\u003c\/strong\u003e Horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e ON-OFF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally Open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Screw Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Mechanical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type:\u003c\/strong\u003e 1-way\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 4.4 inches x 3.6 inches x 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e 33 to 180 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating:\u003c\/strong\u003e IP66\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e UL Listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury Content:\u003c\/strong\u003e Non-Mercury\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 3 year manufacturer's warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.4625 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 752324010615\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Shurflo 359-111-30 bilge pump switch do?\u003c\/strong\u003e The Shurflo 359-111-30 is an automatic float switch that turns your bilge pump on when water rises to 1-3\/4 inches and turns it off once the level drops to 3\/4 inch, so the pump runs only when needed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this switch work with any bilge pump?\u003c\/strong\u003e Yes, the 359-111-30 is designed to work in conjunction with your boat's existing bilge pump as the automatic trigger;
