Mechanical Float Switch

Mechanically activated float switches offer a reliable low current control for dewatering applications.

How It Works

The mechanical float switch control will turn ON (close) when the float tips 45° above -horizontal, indicating a high level, and turns OFF (opens) when the float switch drops 45° below horizontal. Reference Figure 6 and Figure 7. Maximum pumping range is 120 degrees. See Figure 5 below.

Figure 5. Pumping Range (Float Switch)

Pumping Range

The pumping range of the pump is determined by the float switch tether cord. Use Table 3 as guide line to determine your required pumping range. Pumping ranges are based on non-turbulent conditions. Range may vary due to water temperature and cord shape. Please note as the tether length increases, so does the variance of the pumping range.

Design Features

Float switch housings are constructed of high-impact, corrosion resistant polypropylene with mechanically activated, snap action contacts.
