Red Dot 71R6070 High Side Pressure Switch (Normally Closed) – 340 PSI Open / 210 PSI Close

The Red Dot 71R6070 high side pressure switch is designed to protect mobile HVAC systems by monitoring high-side refrigerant pressure. It is a normally closed switch that opens at high pressure (340 PSI) and closes as pressure drops (210 PSI), helping prevent compressor damage during over-pressure conditions.

This switch features a 1/4-inch female flare fitting and two-conductor bare wire leads intended for Packard-style connectors, making it a common service replacement across heavy-duty truck and off-highway HVAC applications. Its pressure range and wide OEM coverage make it a reliable option for mobile air conditioning systems.
