Float Switch FS3

FS3 is a highly reliable condensate overflow switch. It effectively identifies blockages in A/C condensate drains and promptly shuts down the system to protect the structure from water damage.

FS3 is designed with steel mounting brackets, allowing it to be securely attached to the edge of condensate drain pans.

FS3 can be installed on various primary or auxiliary drain pans and will operate correctly even if the installation is off-center.
