The LV-10 Series level switches feature a small float displacement, especially suited for narrow or restricted areas. A standard 1/8 NPT male fitting allows for quick installation in either the top or bottom of the tank or vessel. A sealed SPST switch provides consistent accuracy and high repeatability with the effects of shock, vacuum or vibration minimized. Extremely versatile, the switch is user selectable as normally open or normally closed by simply removing the retaining clip and inverting the position of the float.

For intermediate float displacement, the LV-20 Series will yield long life and greater stability for a broad range of level monitoring requirements. The LV-30 Series larger float displacement is intended for use with liquids of high viscosity, and is well suited for harsh environments. All models share the standard features of the LV-10.

Rated 5 out of 5 by from Good and affordable switch This switch works as described and takes a very small space. Although I paid for the overnight shipping and it took a week.
