Excellent quality. I have been using this for the last 6 months with no problem to keep a 2000 Gallon water tank constantly filled via an 1" RainBird electric valve controlled by a 24 volt AC transformer with tied to a 12 GPM well pump. Works great. Also has secondary float you can use for an 'over-filled' alarm. NICE product! Will buy again!
Update:
Bottom float is a normally closed circuit float, so it allows power through the circuit to activate an electric fill valve. It opens the circuit once the switch floats to a certain level. Now, the top float switch is normally open, and if the water continues to rise to cause the second float switch to float it will "close" that float switch which can set off and "Over fill" alarm.
I mounted this inside a capped 1 1/4" pipe, drilled a hole in the cap to mount the floats inside the pipe. Being this was installed inside a water tank, the fill valve cause ALOT of turbulence which will cause little waves that would ROCK the floats on and off. Having it installed inside the pipe would prevent any waves and just allow the water level to affect the floats. The floats each have about an 1/2" 'on' to 'off' point of movement.
You probably will need a volt or ohm meter to figure out the wiring since there are NO instructions which is THE ONLY REASON I knock off a star.

The description of this product lacks some details. It is approximately 5.5 inches tall. It has two switches that are approximately 1.625 inches apart. One switch uses the Red wires and the other the Black wires. Regardless which way it is oriented (which end is up), the bottom switch has a normally closed connection and the top switch a normally open connection. As liquid rises, each switch in turn will activate to the other state. For my intended use, I only needed the "top" switch to activate a low voltage low current alarm. I'm not sure how both switches could be wired to one pump to keep liquid between the two switches (because the bottom switch opens the connection first). Appears to be good quality.

In short it works, but as others have said documentation would help move the product to a 5 star rating.

Orientation - If you hold the float switch by the wires and let it hang in the air the following is true:
1. The float that is at the bottom (further away from wires/nuts) is connected to the black wires,
2. If you maintain this orientation the float that is at the top (closer to the wires/nuts) is connected to the red wires,

You can change the on/off orientation by changing the logic of the switch from NO to NC.

You can increase or decrease the tipping point of the float switch by moving the tether point up or down a stationary pipe in your water tank. The longer the line between the tether point and the float switch the move travel (gallons) between when the switch turns on or off the pump. The lines must be enclosed in a water proof connection (heat shrink) before water is put in tank. I use my switch in a 2500 gallon cistern/water tank to control a sump pump that I use to move the water to a sand filter pump tank.

I bought one of these a year ago and installed it about 30 feet down in an irrigation well to shut off the pump when the ground water level gets too low. I used a timer to restart the pump after a set period of time. It has worked flawlessly. This level sensor comes with one switch normally open and the other normally closed. I reversed the normally closed switch so that both would be normally open and then wired them in series to make sure the pump would shut off even if one switch failed to open. I made a splash shield out of PVC fittings to keep the sensor from being affected by turbulence. I am ordering another one of these now to install higher in the well to allow fully automatic on/off staging of the pump.

I had tried to use a couple of the cheap plastic float switches but they were totally unreliable.

It came with two red wires and two black wires, and no documentation found showing which pair is for which switch. Just have to use a continuity tester to find out. Red pair for one switch, black pair for the other. Other than that, it appears to be good craftmanship.

I tried to use this as a low level fuel indicator in a gas tank. The float does not float in gasoline. it works perfect in water. The specific gravity of gas to water is close I was hopping it would work. otherwise a very good switch.

It woks like a charm and its fully adjustable, you can take out floats and flip them to reverse the open close signal.

Bought this to automatically fill 5 gallon water bottles from our reverse osmosis system. When used in conjunction with a 12V solenoid valve this makes filling the jugs a "set and forget" affair. Stainless steel and a good price. Can't ask for more.
