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.
