FAQ
What does “normally closed” mean for this switch?
A normally closed (NC) switch remains in the closed position under normal operating pressure, opening only when the pressure exceeds the set threshold, thereby protecting the system from over‑pressure.
Can this switch be used in both automotive and residential HVAC systems?
Yes, the switch is designed for versatile high‑pressure applications, making it suitable for automotive air‑conditioning units as well as residential HVAC and refrigeration systems.
Is the 2‑pin connector compatible with all standard HVAC wiring?
The 2‑pin connector conforms to industry standards and works with most HVAC wiring configurations. For unique setups, the screw terminals provide an alternative secure connection method.
How does the automatic operation improve system performance?
Automatic operation continuously monitors pressure and reacts instantly without user intervention, ensuring timely protection and reducing the risk of compressor damage.
