Description
Overview:
The Yanmar Switch Oil Pressure (MPN 124060-39452) is a genuine on/off oil pressure switch for Yanmar marine diesel engines. Built with a robust, corrosion‐resistant metal body suited to marine environments, it monitors engine oil pressure and switches an electrical circuit to trigger a warning lamp or buzzer if pressure falls below a safe level. This helps protect the engine from damage by prompting timely shutdown or investigation. It is a direct replacement for the original switch, ensuring correct fit and function on a wide range of Yanmar models, including 4JHL-TN and 6AYAM-ET. Designed for consistent performance under vibration, temperature changes, and exposure to oil, it supports reliable day‐to‐day operation and straightforward maintenance in leisure and commercial craft. Genuine Yanmar part for assured compatibility and reliability.
