Miniature Stainless Steel Vertical Float Switch

FS-410

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 383° F (-40° to 195° C), and the FS-410-HT extends that range to -40° to 500° F (-40° to 260° C)!

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.
