Description
Daikin-McQuay 073074002 High Pressure Switch is an essential part that is intended to regulate and measure the refrigerant pressure in HVAC systems with the range of 300 – 400 PSI. This high pressure switch turns ‘on’ or ‘off’ the system depending on the pressure limits set to prevent pressure-related risks to the system and its components such as compressors. Due to its durability for numerous uses in HVAC systems such as air conditioners & heat pumps, it enables correct pressure within them.
