Global Parts 1711744 A/C Compressor Cut-Out Switch

Global Parts A/C Compressor Cut-Off Switch

Global Parts Part Number 1711744 is an A/C compressor cut-off switch used in HVAC pressure control systems. It provides feedback to the engine management system and, on earlier vehicles, can directly shut the compressor off to help prevent compressor damage from excessive pressure.

• HVAC pressure switch for A/C compressor cut-off or cut-out control
• Supports engine management feedback on modern vehicle systems
• Used in high-side pressure monitoring applications
• Direct replacement for select Audi and Cadillac applications
• Cross-references Four Seasons 36678 and UAC SW11159C for the same application
