GPD 1711775 HVAC Binary Pressure Switch A/C Refrigerant Pressure Switch

The GPD 1711775 is an HVAC binary pressure switch engineered for automotive air conditioning systems. This electrical switch monitors refrigerant pressure levels and communicates directly with the vehicle's engine management system to protect critical A/C components from damage.

A binary switch functions as both a high-pressure and low-pressure cutout in one unit. When refrigerant pressure rises beyond safe limits or drops too low — such as when the system has lost its charge or ambient temperatures are too cold — the switch signals the system to disengage the compressor clutch, preventing compressor failure and costly repairs.

Key Features:

• HVAC binary (dual-function) pressure switch
• Monitors both high-side and low-side refrigerant pressure
• Protects the A/C compressor from over-pressure and low-pressure conditions
• Provides feedback signal to the engine control module (ECM)
• Designed to meet or exceed OE fit, form, and function
• Voltage and amperage draw tested for reliable performance
• Backed by GPD's one-year warranty against defects in materials and workmanship

The GPD 1711775 is a direct-fit replacement switch built to restore proper A/C system protection and operation. GPD is a leading manufacturer of aftermarket HVAC components, offering one of the most comprehensive automotive A/C catalogs available.
