Product Details

Description

This High Pressure Control Switch is an essential safety component designed for HVAC and refrigeration systems. Engineered to protect your cooling equipment from excessive internal pressure, this fan-disc style high-limit switch ensures reliable system performance and prevents compressor damage. The switch is calibrated to automatically open the electrical circuit when the system pressure reaches a high-limit threshold of 405 PSI, halting operation to maintain safety. Once the pressure levels return to a safer range of 300 PSI, the switch closes, allowing the system to resume normal operation. This durable pressure limit control is a common replacement part for maintaining the efficiency and longevity of residential and commercial air conditioning and heating units.
