Cleveland Controls DDP-106-272 Switch

The Cleveland Controls DDP-106-272 is a heavy-duty dual switching air flow switch designed for precision monitoring in HVAC and energy management systems. This differential pressure switch features two independently adjustable, factory-calibrated SPDT snap-acting switches mounted on a common foot bracket. Engineered for "proving" applications, it allows contractors to establish a custom adjustable deadband for complex control circuits that require distinct high and low actuation points from a single pressure source.

Constructed with plated housings and a silicone diaphragm, the DDP-106-272 Pressure Switch is compatible with air and combustion by-products. It handles a maximum pressure of 0.5 PSI and operates across a set point range of 0.05" ± 0.02" to 2.0" w.c. This model is specifically configured to change contacts on decreasing pressure at 0.20" w.c. and on increasing pressure at 1.40" w.c., providing reliable differential pressure sensing for industrial-grade blowers, fans, and filtration systems. The 1/4" OD compression fittings ensure a secure, leak-proof connection for rigid or semi-rigid tubing in high-demand environments.

• Dual SPDT Switching: Two separate switches allow for simultaneous control and alarm functions, such as monitoring differential pressure across two points.
• Independent Calibration: Each SPDT switch can be field-adjusted to specific set points, offering maximum flexibility for site-specific requirements.
• Versatile Sampling: Features a common high-pressure inlet and two separate low-pressure connections, facilitating easy integration into positive, negative, or differential-pressure setups.
• Compact Footprint: The DDP-106 series utilizes an exposed switch design for easy access to terminals and adjustment screws during setup.

• What is the maximum pressure rating for this switch? The Cleveland Controls DDP-106-272 is rated for a maximum pressure of 0.5 PSI (13.8" w.c.).
• How should the switch be mounted? For accurate low-point calibration, the diaphragms must be mounted in a vertical plane. Avoid mounting with sample line connections facing upward.
• What electrical ratings does it support? This unit is rated for 120V to 277VAC applications, making it suitable for most commercial air-handling units and industrial processors.
