Product Overview

Mechanically-Activated, Wide-Angle Pump Switch

Pump switches provide automatic pump control.

The Double Float® Master pump switch is designed to directly control pumps up to 15 FLA, 90 LRA, 120 VAC or 240 VAC in non-potable water, water and sewage applications.  

The Double® Float Master pump switch consists of two mechanical float and a splice tube.  The splice tube contains a holding relay which enables the floats to function in series.  The holding relay eliminates pump chatter in turbulent conditions allowing the Double Float® Master pump switch to operate relay control panels for larger pump applications.

This switch is well suited for confined space applications requiring an accurate pumping range.  It is not sensitive to rotation or turbulence.  This switch is voltage sensitive - use with correct voltage.


  • Controls pumps up to 15 FLA, 90 LRA, 120 VAC or 240 VAC
  • Adjustable pumping range of 3 - 48 inches (7.6 - 122 cm) with increased pumping range up to 6 feet (1.8 meters) available
  • Includes standard mounting clamps and boxed packaging
