FLOAT TYPE
Miniature and Micro Floats for Tiny Tanks
Our smallest LS-3 Series switches yet!
Small yes, but with BIG performance.
No other miniature float switches match
our LS-3 specs. These units are ideal for
potable water, medical devices and other
compact appliances, such as printers.
Gems proprietary float enables use in
lighter-than-water fluids. Switches are
made from FDA compliant materials.
