Product Description
The S76575-4 is a Hobbs Corp pressure switch that monitors engine oil pressure in aircraft powerplant systems. When oil pressure rises after engine start, the switch closes an electrical circuit to activate the Hobbs hour meter, enabling automatic flight-time logging for maintenance tracking. Installed in the engine oil gallery or accessory case, this pressure-sensing component follows aerospace standards including MIL-PRF-9395 criteria.
Installation requires verification against the aircraft's Illustrated Parts Catalog and compliance with engine manufacturer maintenance procedures. The switch provides reliable on-condition time recording for general aviation and corporate aircraft engines.
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.
