Excellent product !! I am a frequent buyer at Amazon, but this is my first review ever.. I have purchased many automatic switches for my single phase water pump, but non lasted more than 2-3 months. This float switch is such a hassle free to install with no complicated mechanism. Also a cheap alternative for automatic switches. I highly recommend this product and have ordered a second one too for my friend.

I purchased due to the lower cost as compared to other online site.But the experience in this product is bad.The switch not operating properly due to its internal fixing in the unit.I could not return back as I have taken some time to test the item practically.
What I used it for? Used it in a circuit to turn on/off motor that raises water to the overhead tank in my building. What I disliked: The plastic ring was very difficult to remove and I don't think it is reliable in its functionality. Seller should provide a ring or an appropriate stopper to hold the counterweight in place. Documentation was poor. No explanation of how to adjust the counterweight. No explanation of how the float works and how the counter weight adjustment helps in the working of the float switch. These are the reasons I gave it a 2 star. What I liked: It works as required.
This float switch is suitable for maximum current rating up to 6Amps only to resistivity load for inductive load can be connect up to 3Amps only. for trouble free operation. And this switch most suitable for single phase jet, compressor type, and monoblock motors and 3 phase DOL &star delta. For single phase submersible pump you can use only as tank full OFF, can't use for Automatic ON because start capacitor connected in series to ON push button. But still if you are connecting as auto ON motor may function due to Run capacitor but definitely one day your motor will burn due to starting torque. If your water is more hard then connect this sensor through DC line but additionally you need DC relay or contact and qualified technician.
