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.
The FS-400-S has an operating temperature range of -40° to 368° F (-40° to 187° C), and the FS-400-HT extends that range to -40° to 500° F (-40° to 260° C)!
FS-400-S switches carry CSA Explosion Proof certifications, while FS-400-HT models are certified for General Use. All FS-400 switches are NSF 169 certified.
FS-400 float switches come standard with Normally Open operation. The e-clip at the bottom of the stem is easily removed to change the orientation of the float, changing the switch operation to Normally Closed.
