As the water level drops the contacts separate cutting the electricity. You set the float to activate by the length of the cord to water level. **Q: does anyone know what I can use to send me an alarm when the switch is closed?** A: Thank you for your interest in Little Giant products. I think what you are looking for is our High Water Alarm.

Cord, Grey, 599117Regular price $94.91I'm an avid DIYer. Bought this float switch "Used-Very Good" three weeks ago for $32.83. Never been used! Had the original box been opened? Yes. Of course.But who cares? It works like a champ!Used it to replace my aerobic system lowest float switch, the one that fires up my Sta-Rite 1/2 hp 20 gpm sprinkler pump.Want to test it first before installing? Great idea.I tested mine for continuity THROUGH the piggyback plug, not lead-to-lead. (Check YouTube.)Then I cut off the piggyback plug and butt-spliced this new float switch with the existing wiring, using a wire connector crimper with butt splice head, plenty of assorted sizes of WATERPROOF heat shrink CLEAR tubing, an assortment box of butt splices, and wrapped it all up in 3M Super 33 electrical tape. (All these are, of course, available through Amazon.)(I actually had a double problem. My GFCI circuit breaker was bad, also, and I replaced it, also. Cheapest price was available at Amazon.)(I also took a course offered through the county Health Department which allows me to check my own septic system rather than hiring a septic service to come out every 4 months. I send in a report every 4 months and save about $300 a year.)Like I said. Works like a champ! ### ⭐⭐⭐⭐⭐ Dependable float switch *by on Reviewed in the United States May 28, 2020* After replacing 2 cheaper switches over 3 years, I installed this one. This is a solid replacement switch with better materials and construction than most of the other cheap switches out there. Only slightly more expensive, you get quality and value for what you pay. Easy to install. Very dependable silent operation. Ejector pump operates flawlessly now. ### ⭐⭐⭐⭐⭐ Great replacement float *by on Reviewed in the United States July 25, 2025* Worked perfectly for our septic! ## Frequently Bought Together - Little Giant RFSN-9 115-Volt, Maximum 13-Amp - 1/2 HP, Pump Down Piggyback Tethered Float Switch for Pond, Sump, Sewage or Effluent Systems, 15-Ft.
