Taco SPDT Flow Switch 1 in NPT

This brass paddle flow switch monitors liquid flow in 1 inch NPT piping. It activates between 4.5 and 9.5 gpm with a 10 A contact rating at 125/250 VAC. The unit operates in ambient temperatures from 32 to 151 degrees F at 60 Hz. It suits hydronic heating, cooling or industrial process lines.

Ideal for hydronic and process piping

Installers needing a simple flow-proving device for 1 inch brass piping will find this switch matches the 4.5 to 9.5 gpm range and 10 A rating. It is not suited for systems requiring adjustable set points, electronic output signals or hazardous-location certification. Builders needing larger pipe sizes or higher flow capacities should consider other models.

4.5 to 9.5 gpm actuation range

The switch only closes its SPDT contacts within this specific flow window. If the design flow falls below 4.5 gpm or exceeds 9.5 gpm the device will not operate correctly. Verify the system flow rate against these limits before specifying this part.

Questions about this item

How can I verify the IFSWSBR-1 flow switch is operating correctly after installation?

Confirm the paddle moves freely, then check that the SPDT contacts switch at the 4.5 gpm minimum and 9.5 gpm maximum flow rates while the circuit sees 10 A at 125/250 VAC.

What comes in the box with the IFSWSBR-1 and what must be purchased separately?

The switch body with 1 in NPT brass housing is supplied; pipe fittings, Teflon tape, wiring connectors and any required conduit must be sourced separately.

Which flow-rate version of the IFSWSBR-1 should I choose for my application?

This single model covers 4.5 to 9.5 gpm; select it when your system flow falls within that range and the 1 in NPT connection matches the pipe.
