(1) Pressure switch (high/low) High/low pressure switch (1) detects both high pressure and low pressure in the cooling circuit.High Pressure
When pressure increases abnormally between the compressor and the expansion valve, high/low pressure switch (1) cuts off voltage to the compressor. Voltage to the compressor is cut off in order to protect the circuit.Low Pressure
If the system pressure decreases abnormally between the compressor and the expansion valve, a refrigerant leak is evident. High/low pressure switch (1) cuts off voltage to the compressor in order to protect the circuit. When a refrigerant leak exists, compressor oil is also lost. The pressure switch helps prevent a seizure of the compressor due to a lack of compressor oil.
