Description
The International Comfort Products 1196644 Low Pressure Switch senses suction-side pressure in the system and changes its electrical contact state when the pressure falls below a calibrated limit. It operates through a membrane mechanism that reacts to vacuum or low-pressure conditions, converting movement into an electrical signal for circuit response. Within HVAC systems, it is fitted on the refrigerant line to monitor pressure conditions during operation. Its low-pressure threshold setting provides protection against abnormal suction conditions, preventing unsafe operation and supporting proper compressor control within the cooling cycle.
