Global Parts 1711334 A/C Compressor Cut-Out Switch

A/C Compressor Cut-Off Switch for GM HVAC Systems

Global Parts 1711334 is an A/C compressor cut-off switch used in HVAC systems that rely on pressure feedback to protect the compressor. On modern vehicles, the ECM monitors the A/C system; on earlier applications, this switch can directly shut the compressor off when pressure conditions rise too high.

• Type: switch; compressor switch high pressure; blue 2-terminal
• Provides pressure-based feedback to the engine management system
• Used in A/C compressor protection circuits on select GM vehicles
• Direct replacement style for service on factory HVAC systems
• Global Parts part number 1711334
