The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Switch monitors system pressures, aiding in proper and efficient control of the compressor, fans and system levels. An improperly functioning A/C Pressure Switch will provide erratic or inaccurate actuation and operation, severely affecting system performance and function. Without reliable and accurate actuation from a properly functioning A/C Pressure Switch, critical components and the system as a whole are left unregulated and unprotected which can lead to excessive wear and tear on critical components and costly system damage.

Product Features:

• Designed and manufactured with high quality materials, industry leading electronic components and strict quality controls. Engineered to meet or exceed OE performance and to meet the uncompromising demands of service professionals.
• Direct fit replacement matches proper OE fit, form, and function and ensures trouble free installation of your A/C Pressure Switch.
• All units are tested using advanced end-of-line equipment that pressurize the A/C Pressure Switch, confirm proper calibration and functionality, and check for leaks to ensure each A/C Pressure Switch meets manufacturing specifications before packaging.

Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.
