Series FS-410 Miniature Stainless Steel Vertical Float Switches are proof that excellence comes in small packages.
Their compact size -- less than 2.35” from top of threads to end of stem -- all stainless steel wetted materials, and
user-reversible switch orientation, make them any easy choice for OEM, water and wastewater, and chemical appli-

cations. All Series FS-410s carry NSF certications, and Series FS-410-S switches are CSA Explosion Proof.

Features
