The 4421133-000 is a cabin altitude pressure switch that monitors pressurization integrity on aircraft. This electrical sensor closes a circuit when cabin altitude exceeds a preset threshold, triggering oxygen mask deployment or warning systems. Installed in oxygen control circuits, the switch provides automatic protection during rapid depressurization events.
Installation follows the aircraft maintenance manual and wiring diagram specifications. Verify operation during routine pressurization system checks to ensure reliable oxygen system activation when needed.
