Review on Stainless Steel Water Level Sensor Switch With Float Controller - Ideal For Fish Tanks, Cisterns, Aquariums, Pools, And Ponds - Single Plastic Ball Float For Liquid Detection (1 Pc) by Brady Penczak
needs a relay best in my review
Ordered 1 for hydroponic watering. Switch controls a 12vdc pump that draws 300ma. The first switch failed to reliably cycle on/off and was promptly replaced. While contacts are rated at 500ma and pump draws 300ma I believe pump startup current spike exceeds 500ma rating causing contacts to stick. Ended up using $5, 12vdc EMR (general purpose automotive relay) from auto store with this switch. Relay/switch combo has been working like a charm for 3 weeks. Was impressed with solid stainless construction and claim of up to 2 million cycles.
- Made of high-quality stainless steel, this water level sensor switch guarantees reliable and accurate liquid detection for fish tanks, cisterns, aquariums, pools, and ponds
- The stainless steel construction may make the sensor susceptible to damage from rust or corrosion over time
