We stock a range of precision float switches. These are attached to a pivot bracket fitted to a stainless steel mounting clamp. These are designed to be fitted to the body of a submersible pump or an appropriate inlet pipe.
The on and off levels of the switch are precise, as the switch remains in a fixed position. This is particularly useful when the switch is controlling the filling levels for topping up a tank with mains water.
By limiting the movement of the switch, the level of water is easily controlled (typically 90mm level rise), thereby leaving the maximum tank volume free to collect the next rainfall event.
Switches are normally fitted to the body of a submersible pump, or if used within a break tank, fitted to inlet pipework. They available in two versions;
Red float for dry-run protection (when it drops, it switches the pump off)
Yellow float for mains water top-up (when it drops, it switches the mains water top-up on, then off again when switch rises.) Approximately 9cm difference in water levels between on and off. Could also be used for emptying a tank.
Switches are available with clamps to to fit 50mm, 100mm and 150mm diameters, and with either 3m, 10m or 20m pre-fitted cables.
