REFRIGERANT PRESSURE SWITCH CONSTRUCTION


id074000103700

•  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.

Medium-pressure switch

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