1-inch SPDT paddle flow switch

The Taco IFS01BR-1 is a brass-bodied flow switch designed for 1-inch NPT piping. It uses a paddle mechanism to detect liquid movement in plumbing and hydronic systems. The switch activates between 4.5 gpm and 1,500 gpm. It suits installers who need a direct-acting flow-proof device.

Sustained operation within rated limits

The switch handles continuous media temperatures up to 250 degrees F and ambient temperatures up to 176 degrees F. Its SPDT contacts are rated for 15 A at 125/250 VAC and 15 A at 125/250 VAC on the DC rating line at 60 Hz. Brass housing resists corrosion during long-term exposure to heated water.

Brass NPT construction for daily service

The 1-inch NPT connection threads directly into standard pipe fittings without adapters. Brass housing withstands typical hydronic pressures and temperatures without deformation. The paddle design tolerates debris that would foul smaller orifice switches. Installers who need a flanged or sweat connection cannot use this model.

Questions about this item

How much power does the 1" SPDT paddle switch draw when it runs continuously at 1500 gpm?

The switch itself consumes negligible power; it simply opens or closes a circuit rated for 15 A at 125/250 V AC or 15 A at 125/250 V DC.

What piping and electrical items must already be on site for this flow switch to install and operate?

You need a 1 in NPT threaded pipe connection, a system that operates between 4.5 gpm and 1500 gpm, and a control circuit compatible with the 15 A, 125/250 V AC or DC contact rating.

Will this brass paddle switch work reliably alongside an older 1 in iron pipe system that sees water up to 250 °F?

Yes — the brass housing and paddle are rated for media temperatures from 32 °F to 250 °F, matching the temperature range of the existing iron pipe.
