Product Description
The 674-3 is an aircraft pressure switch that triggers an electrical signal when hydraulic pressure reaches a preset threshold. Using diaphragm or piston sensing elements, this switch interfaces with MS-series fittings and connects to landing gear system logic and annunciation circuits. When system pressure crosses the set point, the switch actuates to signal pressure conditions to flight deck instruments or control systems.
Installation requires verification of the exact sensing configuration and adjustment per aircraft maintenance manual specifications and component documentation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
