•  A triple pressure type has been adopted.

•  Consists of the low/high-pressure switch that protects the refrigerant cycle by cutting the A/C signal when pressure in the refrigerant cycle is abnormally high or low, and the medium-pressure switch that outputs an idling increase signal according to the A/C compressor operation load.

•  When pressure is abnormal, the refrigerant pressure switch turns off and cuts the signal sends to the magnetic clutch, thereby stopping the A/C compressor.

•  When the refrigerant pressure is approx. 1.39 MPa {14.2 kg/cm², 202 psi} or more, the contact is energized and an idling increases signal is output to the PCM.
