The process of magnetic clutch being engaged is shown below.
Main Switch (3) ON → A/C Switch (4) ON → Blower Switch (12) ON (Low, medium or High) → Compressor Relay
(5) ON → Thermo Switch (6) ON (the thermostat temperature is more than 4 °C (39.2 °F)) → A/C Pressure Switch (7)
ON (if refrigerant pressure is between 0.21 MPa (2.1 kgf/cm
2
, 30 psi) and 265 MPa (27 kgf/cm
2
, 384 psi) → Magnetic
Clutch of Compressor Engaged.
