• Form C Contacts: Reliable SPDT switching allows for flexible wiring configurations for both normally open and normally closed circuits.
• Industrial Build: Includes a protective cover and durable 1/8 NPT threaded ports to prevent leaks and withstand vibration.
• Technical Compatibility: Frequently cross-referenced for antunes 8021204007 specs in commercial boiler and HVAC control loops.

Common HVACR Questions

How do I calibrate the trip point on the Antunes 8021204007?
Remove the cover and use the internal adjustment screw while monitoring the system with a calibrated manometer to ensure the switch trips at your specific pressure set point.

Can this switch be used for both positive and vacuum pressure?
Yes, the air pressure sensing switch can be configured to monitor positive, vacuum, or differential pressure depending on how the high and low ports are piped.

What electrical load can the SPDT contacts handle?
The Antunes Controls 8021204007 is typically rated for pilot duty and general-purpose electrical switching; always verify the current draw of your controller or motor starter against the internal nameplate specifications.
