This high-performance low pressure switch is an essential safety component for HVAC systems, including air conditioners and heat pumps. Designed to protect the compressor from damage, this air-proving pressure switch monitors refrigerant levels and interrupts the electrical circuit if the system pressure drops below a safe threshold. It features a precise 35 PSIG open setting to prevent operation during low-pressure conditions and a 55 PSIG reset point to ensure the system resumes once safe levels are restored. Ideal for maintaining the longevity and efficiency of residential and commercial cooling equipment, this switch is a critical replacement part for preventing compressor burnout and system failure.
