The A.J. Antunes 8102111203 High Gas Pressure Switch is a safety part used to control high gas pressure in HVAC systems including refrigeration equipment. This switch is a differential pressure type and measures the pressure within the system. When the pressure rises above the set limit, the switch comes on usually it is a normally closed-type switch. Depending on the type of safety mechanism this action can turn the compressor off, sound an alarm, or open a solenoid valve to let out pressure.
