## Questions & Answers

**Q: Which position is switch on and which position is off?**
A: The contact is closed when the float is in the horizontal position. (It can be used for filling and emptying a container simply by mounting the switch so that it floats up or floats down.) I have used them to fill a water barrel in a greenhouse and to empty a sump in a basement. Two switches and a relay required in both cases for an auto fill or empty system.

**Q: If the tails are connected out of water is the rest of the switch fully submersible?**
A: Yes, but they are intended to be fitted through a hole in the container side. Much the same as a float valve in a water storage tank. The moving part of the mechanism appears to be a magnet that moves closer to a reed switch encapsulated in plastic.
