Daikin-McQuay 106035801 Pressure Switch

The Daikin-McQuay 106035801 High Pressure Switch is an essential safety component engineered for precise refrigerant pressure monitoring in commercial HVAC systems. This SPST-NC (Single Pole Single Throw, Normally Closed) switch serves as a critical fail-safe, designed to interrupt the control circuit when discharge pressures exceed safe operating limits. With a robust weatherproof enclosure, this switch is built to withstand the rigorous vibrations and thermal cycling common in industrial chiller applications and rooftop package units.

Operating on a 24V AC control voltage, the 106035801 ensures rapid system cut-out to prevent compressor damage and potential coil failure. Its compact design allows for direct mounting on the high-side liquid or discharge line, providing high-accuracy response with minimal pressure drop. For veteran contractors, this OEM HVAC replacement part is the standard for maintaining the integrity of Daikin and McQuay equipment without the risks associated with generic high pressure controls.

• System Protection: Automatically opens the circuit during high-pressure events to prevent terminal compressor failure.
• Durable Construction: Features a high-grade weatherproof enclosure suitable for outdoor condenser environments.
• OEM Compatibility: Exact Daikin-McQuay 106035801 specifications ensure seamless integration with existing control wiring.
• Electrical Reliability: Designed for low-voltage 24V AC operation with a high-cycle life rating for industrial use.

What is the contact configuration for the 106035801?
This is an SPST-NC (Normally Closed) switch, meaning the circuit stays closed during normal operation and opens upon reaching the high-pressure trip point.

Can this pressure switch be used on 120V circuits?
No, this specific model is rated for 24V AC control circuits. Verify your transformer output and coil voltage before installation to avoid electrical damage.

Does this switch require manual resetting?
The 106035801 is typically an automatic reset pressure switch, though high-side safety standards may vary by specific unit model; always check the equipment wiring schematic for the manual reset relay requirement.
