Pressure switch for HVAC systems

The Robertshaw 2374-506 is a conduit-box air pressure switch designed for commercial and residential HVAC equipment. It handles air filtration, furnace control and humidity detection tasks with a stainless-steel housing rated for 1 A pilot duty at 120 VA and 5 A at 120 to 277V AC or 28V DC.

SPDT screw-terminal wiring for panel mounting

The switch uses a single-pole double-throw contact form with screw terminals, allowing direct integration into control panels without additional connectors. Its conduit-box housing protects the terminals while the adjustable differential pressure setting of 0.02 in wc lets technicians calibrate the actuation point on site.

Adjustment tool and mounting hardware included

An adjustment tool ships in the box so the differential pressure can be set without sourcing a separate instrument. Mounting hardware is also supplied, letting installers secure the unit to the panel immediately instead of ordering brackets or fasteners separately.
