APG Miniature Stainless Steel Vertical Float Switch FS-410

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 applications. All Series FS-410s carry NSF certifications, and Series FS-410-S switches are CSA Explosion Proof. Excellence comes in small packages. At less than 2.35 inches (60 mm) in total length, and an all stainless steel construction capable of operating temperatures up to 500° F, the series FS-410 float switch brings high performance to small spaces.

Small Package

From the top of the mounting threads, to the bottom of the stem, the FS-410 is less than 2.35" long, and the float is just under 1.2" wide.

Temperature Ranges

The FS-410-S has an operating temperature range of -40° to 368° F (-40° to 187° C), and the FS-410-HT extends that range to -40° to 500° F (-40° to 260° C).

Certifications

FS-410-S switches carry CSA Explosion Proof certifications, while FS-410-HT models are certified for General Use. All FS-410 switches are NSF 169 certified.

User Reversible Operation

FS-410 float switches come standard with Normally Open operation. The e-clip at the bottom of the stem is easily removed to change to orientation of the float, changing the switch operation to Normally Closed.
