Reed Switch Designfor High RepeatabilityUser Selectable,Normally Open orNormally ClosedSPST Switch

The LV-10 Series level switchesfeature a small float displacement,especially suited for narrow orrestricted areas. A standard 18 MNPTfitting allows for quick installation ineither the top or bottom of the tankor vessel. A sealed SPST switchprovides consistently high accuracyand repeatability while minimizingthe effects of shock, vacuum, orvibration. Extremely versatile, theswitch is user selectable as normallyopen or normally closed by simplyremoving the retaining clip and

inverting the position of the float.For intermediate float displacement,the LV-20 Series will yield long lifeand greater stability for a broadrange of level monitoringrequirements. The LV-30 Serieslarger float displacement is intendedfor use with liquids of high viscosity,and is well suited for harshenvironments. Both models sharethe standard features of the LV-10.
