The FSK-16 is a vertical mechanical float switch for a compatible pump. It controls start and stop as water rises and falls; it is not a pump or a high-water alarm.
Ask support to confirm motor-load compatibility before ordering if the rating is unclear. A matching plug alone does not establish compatibility.
