Global Parts 1711764 A/C Trinary Switch

A/C Trinary Switch for Hyundai and Kia

Global Parts 1711764 is an A/C trinary switch used in HVAC systems that rely on electrical feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage A/C operation; on earlier applications, the switch can help shut the compressor off before damage occurs.

Compatible with select Hyundai Tucson, Tiburon, XG350, XG300, and Kia Optima, Sedona, and Spectra applications, this part number 1711764 is a direct-fit style replacement for vehicles that use the listed switch configuration.

• Electrical A/C pressure switch for compressor control and system feedback
• Used in HVAC systems that communicate with the ECM
• Helps protect the compressor by signaling unsafe operating conditions
• Fits select Hyundai and Kia applications with the listed OE-style switch setup
• Cross-references UAC SW11460C for the same application

Detailed Product Information

This A/C trinary switch is designed for vehicles that monitor refrigerant system conditions through an electrical input. In Hyundai Tucson and Hyundai Tiburon applications, as well as Kia Optima, Sedona, and Spectra models, the switch supports compressor control by relaying pressure-related feedback to the vehicle’s HVAC and engine management systems. Global Parts 1711764 is a practical replacement when the original switch is no longer responding correctly or when A/C operation is interrupted by a faulty pressure signal.

This part number 1711764 also cross-references 97752-38001 and SW-566 for the same application.

What It Helps Address

• A/C compressor not engaging
• Compressor cycling off due to pressure signal issues
• Faulty feedback to the ECM or HVAC control circuit
• Intermittent air conditioning operation
• Protection shutdowns caused by a failed trinary switch
