Universal Air SW4070C HVAC Binary Switch

Universal Air SW4070C HVAC Binary Switch

The Universal Air SW4070C is a binary HVAC switch used in air conditioning control circuits to monitor system pressure and help protect the compressor. It is a direct-fit style service part for technicians searching for an HVAC binary switch, Binary HPCO/LPCO switch, or SW4070C replacement.

Key Features

• Binary high-pressure and low-pressure cutoff switch for HVAC systems
• Supports pressure-based compressor protection in automotive air conditioning circuits
• Universal Air Binary HPCO/LPCO Switch line for HVAC service applications
• Part number SW4070C for fast identification and ordering

Product Details

Built for HVAC switch service, the SW4070C monitors refrigerant pressure conditions and signals the system when pressure moves outside the normal operating range. That function is important for maintaining compressor protection and stable A/C operation. Search terms such as HVAC binary switch, pressure cutoff switch, and SW4070C are commonly used by buyers looking for this type of replacement part.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• A/C compressor cycling caused by pressure switch faults
• System shutdown from an inoperative high-pressure cutoff circuit
• Low-pressure protection issues in the HVAC control circuit
• Intermittent air conditioning operation tied to switch failure

Installation Notes

Verify the connector style, pressure switch location, and system specifications before installation. Confirm refrigerant charge and inspect related HVAC wiring, relays, and pressure controls during diagnosis. Use the vehicle service information for the exact test procedure and replacement steps.

Quality Assurance

Universal Air supplies HVAC service components for automotive air conditioning repair, and the SW4070C is identified as a Binary HPCO/LPCO Switch for pressure-based system control.
