## Questions & Answers

**Q: Is swithch on in down position and off in up?**
A: No, this is a "pump down" switch which clicks on when the liquid raises the float switch and off when down.

**Q: What contactor goes with this and your well pump?**
A: This switch is not generally used with a well pump.  A bladder tank with a pressure sensitive switch is used to regulate your well pump.

**Q: Can this be used to switch a 24 vdc, 370w well pump? i need to stop the pump if water level falls below a certain level.**
A: Theoretically you can. This particular float switch has a cut on as it's raised and a cut off once it reaches a low point which is what you are looking for. This float switch is designed for two hot leads of 120 volts each for a total of 240 volts. However you can break both DC leads. Be aware that this is a pump down float, and it will shut off if the water gets low, and it won't come back on until it reaches a specified cut back on position. You are restricted with the single float to find a happy medium between cut on and cut off. With that said you don't want to cut on and off position in the same place because the pump will be going on and off non-stop. The short answer is yes it will work if wired correctly.

**Q: Would 2 of these control a well pump filling a 1,500 tank? I want the pump to stop when tank is full and start once tank is empty.**
A: I have mine set up in a 300 gallon storage tank to replenish 50 gallons at a time
