Ideal for sump pumps, alarms, and automated water control systems, this sensor offers durable performance with corrosion-resistant stainless steel construction. ## Description Cable Length : 350mm/ 13.8";Color : Silver Tone, Black, Red; Weight : 67g;Package Content : 1 x Water Level SensorEach Float Ball Size : 28 x 26mm/ 1.1" x 1"(D*H);Screw Thread Diameter : 9.5mm/0.27";Retaining Clip Diameter : 16mm/ 0.6";Body Total Length : 166mm/ 6.5"Max Contact Resistance : 100m ohm; Temperature Rating : -10 ~ +85 Degree; Float Ball Material : Stainless Steel; Float Body Material : Stainless SteelThis product is used to sense the level of liquid within a tank. It may actuate a pump, an indicator, an alarm, or other device. It can be easily converted from normally open to normally close by inverting the float.

(If you have any questions about this product, welcome to email consultation, we will reply you within 24 hours!) Review: JUST WHAT I NEEDED - The dual float will be used in a remote sump pump control. Bottom float will cycle as needed, top float is back up to bottom float and high event latching alarm. Float switches trigger timing circuits to allow the pump time to lower sump pit water level. A third float switch near the bottom of the pit acts as a pump shut off safety to prevent totally emptying the pit and running the pump dry. Review: Not working - Stopped working properly after only few hours ## Features - Please see clearly the size and function of this product when you buy it. Thank you for buying!

Bottom float will cycle as needed, top float is back up to bottom float and high event latching alarm. Float switches trigger timing circuits to allow the pump time to lower sump pit water level. A third float switch near the bottom of the pit acts as a pump shut off safety to prevent totally emptying the pit and running the pump dry. ### ⭐ Not working *by A***R on March 18, 2020* Stopped working properly after only few hours ### ⭐⭐ Works just the opposite *by B***. on May 7, 2022* This switch works just the opposite than it should. When the float is up turns the water on, when the float is down turns the water off unless I'm missing something ## Frequently Bought Together - LUOYIMAO Wired Water Liquid Level Sensor Dual Ball Stainless Steel Float Switch Silver Tone (150mm-S) - Electromagnetic Power Relay, 8-Pin 10 AMP 24V AC Relay Coil with Socket Base, LED Indicator, DPDT 2NO 2NC - MY2NJ [Applicable for DIN Rail System] - mxuteuk 2pcs HH52P DC 12V Coil 8 Pin 5A DPDT LED Indicator Electromagnetic Power Relay, with Base, with DIN Rail Slotted Aluminum --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/119539530-wired-water-liquid-level-sensor-dual-ball-stainless-steel-float](https://www.desertcart.ec/products/119539530-wired-water-liquid-level-sensor-dual-ball-stainless-steel-float) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-07*
