This switch is simple to install and incorporate into your pumping design. Use it to turn your solar or 240v water pump off when your water tank reaches a high level and back on again as the level drops. Conserve precious water and save power.
Decent tank switch and easy to install for someone of any ability. I run this off a small tank with a submersible pump for irrigating 10 mandarin trees. Very cheap way to control the pumps without running dry. 5 stars.
