Oil Pressure Switch Yanmar – 124060-39452

This oil pressure switch is a genuine OEM Yanmar part used for the engine alarm system. The switch activates a warning signal when oil pressure drops below the specified level (0.2 kg), helping to protect the engine from damage.

This switch is intended for the alarm system, not for displaying oil pressure on a gauge. For oil pressure readings on a dashboard gauge, a separate oil pressure sensor is required.

This is a genuine Yanmar OEM product.
