Light weight and simple working principle,high reliability. It can be easily converted from normally open to normally close by invertin the float. 3. Use them with hydroponics, saltwater tank, freshwater tank, gardening, pet bowls, fish tanks, filtration, pumps, ponds, basement alarms, boats, air condition drain pans, aquarium, ice machines, coffee pots, marine,evaporator coils, Please Note: because the current that the switch can carry is much little(above 0.5A), you must use a relay or contactor when it is connected by a load, relay and contactor are not included here.

Review: Value for money - Works perfectly for auto top off in aquarium world. It can be used Normally closed (default) or as normally open ( just remove the float and put it in opposite direction) Absolutely value for money

## Questions & Answers

**Q: Description says right angle but the image apprears to be an an axial design.**
A: It’s a linear actuator, but it can be screwed through the wall of a tank at a right angle to the water.

**Q: can it works with a 3V micro water pump to start and stop?**
A: The float switch is best to activate a relay.  I've experienced problems with float switches failing and shorting thus running the pump continuously and overflowing.  I run my system with 12VDC pumps and Relays... Hope this helps

**Q: Is the wire-side completely waterproof? I need to submerse several in a tank at various levels.**
A: they appear sealed, but I added silicone to be sure.

**Q: Do these have a closed resistance? I'd like to daisy chain several and read a collective value for how many are activated?**
A: very low resistance.  I believe it's a reed switch.  I use them with a relay board to switch a 120VAC pump and they work perfectly.

### ⭐⭐⭐⭐⭐ They're holding up so far.
*by D***M on June 29, 2024*

I have an effluent tank that pumps up hill to my septic field and I wanted a way of measuring the level in the tank. I already track the pump on and off time and with a few datapoints on the level I can really tell how well the system is working. Do I really need it? Who knows, but I like doing little projects like this and analyzing the data... What I do know is that an effluent tank is a NASTY environment and is very hard on so many different types of material. I don't know what these are made of but they've been working great for about 6 weeks now. I have a level gauge in my basement so I can always tell where the tank level is, a second alarm so I get a pre-warning and it all datalogs to a server so I can remove view it. I chose these because they seemed simple and were sealed. I use them with an ESP32 and they are normally open, close when the float raises up. I installed them threaded side down, but I believe you can remove the clip and flip the magnet to reverse the open and closed position. It's a magnetic switch so it should last a long time.
