It turns on when water reaches 1-3\/4 inches and shuts off once the level drops to 3\/4 inch, giving reliable, hands-free bilge water evacuation without constant monitoring. A protective cage shields the float mechanism from debris that could otherwise interfere with its operation, making it well suited to harsh marine bilge environments.\u003c\/p\u003e\u003cp\u003eInstallation is straightforward thanks to an easy snap-into base design that supports either remote or direct mounting, along with a 3 inch tinned wire assembly for making electrical connections. A manual test feature lets you verify pump operation on demand without waiting for water to reach the trip point. For maximum performance, mount the switch horizontally. The switch is ignition protected and rated for 12\/24 VDC systems, drawing up to 12 amps at 12 volts DC or 6 amps at 24 volts DC, and it operates across a temperature range of 33 degrees F to 180 degrees F. Its snap-in baseplate is designed to work with SHURFLO 380, 500, 700, and 1000 GPH bilge pumps. Backed by a 3 year manufacturer's warranty, this switch is a durable, drop-in solution for automating bilge pump control on boats of all sizes.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
