Carrier HK06WC090 SPST Pressure Switch

The Carrier HK06WC090 SPST Pressure Switch is used in HVAC systems and highly functional part for regulating fluids or gases depending on the pressure changes in a system. It works as a single-pole single-throw switch and has one normally open contact which closes when the set pressure is attained. This makes it suitable for use in a host of applications because of this simple yet effective mechanism. When the system pressure goes high than the set pressure, the diaphragm or piston moves and closes the electrical circuit by operating the switch.
