Verified OEM Direct-Fit Excavator Engine Protection Switch designed for ISUZU 6WG1 diesel engines, primarily installed in Hitachi ZAXIS series excavators.
This oil pressure switch monitors engine oil pressure in real time, ensuring proper lubrication system operation and triggering alarm or protection signals when oil pressure deviates from normal range, preventing engine damage due to insufficient lubrication.
Mounted on the engine main oil gallery, the switch contains a diaphragm that displaces under oil pressure, making or breaking an electrical circuit when pressure reaches the set threshold of approximately 0.3 bar. This sends a signal to the dashboard or ECU to trigger warning lamps or engine protection programs when oil pressure drops below safe values.
