Stainless Steel Vertical Float Switch

FS-400

Compact, Durable, Easy to Use

With all stainless steel wetted materials, operating temperatures up to 500° F, and a switch rated for VDC and VAC operation, the series FS-400 float switch fits a wide range of applications in two standard configurations.

Compact Size
From the top of the mounting threads, to the bottom of the stem, the FS-400 is less than 3.5" long, and the float is just over 2" wide.

Temperature Ranges
The FS-400-S has an operating temperature range of -40° to 383° F (-40° to 195° C), and the FS-400-HT extends that range to -40° to 500° F (-40° to 260° C)!

User Reversible Operation
FS-400 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.
