Cleveland Controls DDP-106-298M Switch

The Cleveland Controls DDP-106-298M is an industrial-grade air pressure sensing switch designed for critical HVAC proving switch and energy management applications. This high-performance unit features two independently adjustable SPDT snap-action switches mounted on a single heavy-duty common foot bracket. Built for precision, it allows technicians to establish an adjustable "dead band" for complex control circuits requiring both high and low actuation points. This dual air pressure switch is capable of monitoring two separate pressure sources or sensing differential pressure for HVAC system diagnostics.

Engineered for versatility, the DDP-106-298M operates within a set point range of 0.05" w.c. to 2.0" w.c. and is rated for 120V to 277Vac. The internal diaphragms are constructed from durable silicone, making the unit compatible with combustion by-products and air that will not degrade the material. For reliable field installation, the unit features 1/4" OD sample line connections and 90-degree quick-connect terminals. To maintain calibrated accuracy and prevent nuisance tripping, the Cleveland Controls pressure switch must be mounted with the diaphragm in a vertical plane in a vibration-free environment.

• Dual-Switching Action: Features two independent SPDT switches for versatile control of alarm and proving functions.
• Wide Field Adjustability: Allows for precision tuning between 0.05" and 2.0" w.c. to meet specific heating and cooling maintenance requirements.
• Robust Construction: Plated housings and high-grade silicone diaphragms ensure long-term stability in commercial air pressure monitoring.
• Extended Electrical Compatibility: Multi-tap voltage capability from 120V to 277Vac supports a broad range of industrial and commercial equipment.

How do I set the dual actuation points? Each switch assembly on the Cleveland Controls DDP-106-298M has its own adjustment screw. Turning the screw clockwise increases the set point, allowing you to create a specific operating window between the two independent contacts.

What media is compatible with this sensing switch? This differential air pressure switch is designed for air or combustion gases that are non-corrosive to silicone and plated steel. It is frequently used in furnace troubleshooting to prove draft or airflow.

Can this replace a single-diaphragm pressure switch? While it can provide more functionality, this dual-switch model is specifically used in HVAC system upgrades where two separate electrical signals are required from a single high-pressure source.
