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·cm 2, 202 psi} or more, the contact is energized and an idling increases signal is output to the PCM.
