Review: Fonctionne bien - parfait remplacement pour ma pompe de puisard à batterie. Beaucoup plus précis et plus facile à positionner dans un endroit restreint que mon ancienne flotte à gravité (tethered float). Mécanisme plus fiable. Review: Don't buy the reed switches, these are much more reliable! - Don't buy the reed switches, they don't last. In addition, the reed switches fail with the circuit CLOSED. That burnt out 3 of my bilge pumps before I realized why the pumps failed. I run my bilge pump/float switch directly connected to a 100 watt solar panel (no battery). When the cheap reed switches fail they run the pump continuously until it overheats and dies—because all the water has been evacuated long ago. Since I bought one of these more expensive steel roller ball switches I've had no bilge pump failures every month or two. My pumps run all day off and on and those cheap reed switches can't take it. ## Features - 2-Year Warranty! - Enhanced sealing construction for added durability - Steel ball bearing activation superior to electronic reed system - 18 gauge marine grade wire - Perfect float switch sensor for your bilge pump ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RL8NRJF | | Best Sellers Rank | 283,902 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 234 in Boat Bilge Pumps | | Brand | Seaflo | | Colour | White | | Country of Origin | China | | Customer Reviews | 4.3 out of 5 stars 353 Reviews | | EU Spare Part Availability Duration | 4 Years | | Flow Rate | 18 Gallons Per Minute | | Item Dimensions L x W x H | 7L x 6.2W x 11.7H centimetres | | Item Weight | 127 g | | Manufacturer | SEAFLO | | Material | Steel | | Model Number | SFBS-018-02 | | Part Number | SFBS-018-02 | | Power source | Battery Powered | | Product Style | Bilge | | Product dimensions | 7L x 6.2W x 11.7H centimetres | | Style | Bilge | | UPC | 647336949742 | | Voltage | 24 Volts (DC) | ## Product Details - **Brand:** Seaflo - **Colour:** White - **EU Spare Part Availability Duration:** 4 Years - **Item weight:** 0.28 Pounds - **Material:** Steel - **Maximum flow rate:** 18 Gallons Per Minute - **Power source:** Battery Powered - **Product dimensions:** 7L x 6.2W x 11.7H centimetres - **Style:** Bilge - **Voltage:** 24 Volts (DC) ## Images ![SEAFLO 02 Series Bilge Pump Float Switch - 12V/24V 18A Automatic Water Level Switch with 1m 16 AWG Leads, Sensor for Marine Boat Fresh & Salt Water Bilge Pumps, 4-Year Warranty - Image 1](https://m.media-amazon.com/images/I/51B6r+8-jAL.jpg) ![SEAFLO 02 Series Bilge Pump Float Switch - 12V/24V 18A Automatic Water Level Switch with 1m 16 AWG Leads, Sensor for Marine Boat Fresh & Salt Water Bilge Pumps, 4-Year Warranty - Image 2](https://m.media-amazon.com/images/I/51StM4ji0ML.jpg) ![SEAFLO 02 Series Bilge Pump Float Switch - 12V/24V 18A Automatic Water Level Switch with 1m 16 AWG Leads, Sensor for Marine Boat Fresh & Salt Water Bilge Pumps, 4-Year Warranty - Image 3](https://m.media-amazon.com/images/I/81heICtC+iL.jpg) ![SEAFLO 02 Series Bilge Pump Float Switch - 12V/24V 18A Automatic Water Level Switch with 1m 16 AWG Leads, Sensor for Marine Boat Fresh & Salt Water Bilge Pumps, 4-Year Warranty - Image 4](https://m.media-amazon.com/images/I/71j8EDCmBTL.jpg) ![SEAFLO 02 Series Bilge Pump Float Switch - 12V/24V 18A Automatic Water Level Switch with 1m 16 AWG Leads, Sensor for Marine Boat Fresh & Salt Water Bilge Pumps, 4-Year Warranty - Image 5](https://m.media-amazon.com/images/I/71qk5CCA70L.jpg) ## Questions & Answers **Q: What makes this switch a "32V"? Why not 120V?** A: This float switch is capable of handling 12V, 24V, and 32V systems. Unfortunately, it is not compatible with 120V systems. **Q: Can this switch run 2 pumps?** A: The switch has an 18A rating, but I wouldn't recommend using that high of a number for reliable operation. Smaller bilge pumps run at approximately 3A, but have an inrush current much higher (at least 3X, so 9A or so). In theory you could probably get by running 2 small pumps, but I wouldn't recommend it. I've used a lot of these over the last 30 years and these switches are the weak point of the bilge system, so I typically try to have 2 complete float/pump systems for redundancy (I'm assuming this is for a boat application). **Q: Would i be able to turn off a pump when a water level is reached if switch the polarity?** A: I do not think so. The switch itself is sealed and switching the way the wires are connected will not change polarity because switches have no polarity. Usually switches in this price range will have only one set of contacts which are open with float down and closed when float is up. **Q: How do you get a new one under warranty?** A: Call the factory.... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fonctionne bien *by M***E on 25 May 2024* parfait remplacement pour ma pompe de puisard à batterie.
