SJE-Rhombus Double Float Pump Switch Descriptions

Mercury activated, wide-angle switch designed to control pumps up to 1 HP at 120 VAC and 2 HP at 230 VAC.

The Double Float® pump switch is designed to directly control pumps up to 1HP at 120 VAC and 2HP at 230 VAC in non-potable water, water and sewage applications.

The Double Float® pump switch consists of two floats and a splice tube. Each float contains a heavy-duty mercury switch. 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® 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.
