SJE-Rhombus (Detroit Lakes, MN) has enhanced the design of the Double Float Master pump switch for use in a wider range of applications. The new mechanical pump switch has an enhanced pumping range of 3 to 48 inches and an increased amp rating of 15 FLA at 120 VAC or 240 VAC. The Double Float Master pump switch consists of two narrow-angle mechanical floats and a splice tube, which contains a holding relay that enables the floats to function in series. The holding relay eliminates pump chatter in turbulent conditions, allowing the pump switch to operate relay control panels for larger pump application.
