Product Description

The G309 series Sealed Clamp Subminiature Micro Switch is a sealed subminiature micro switch designed specifically for charging station and charging gun applications. It boasts excellent waterproof and dustproof performance, adapting to harsh operating environments. Its IP67 waterproof and dustproof rating ensures long-term stable operation in high-humidity and high-dust environments, making it particularly suitable for electric vehicle charging facilities. Whether in charging stations or charging guns, the G309 series micro switch provides precise operation during power connection and disconnection, ensuring the safety and efficiency of charging equipment.

As an automotive micro switch, the G309 series not only features an exceptionally long mechanical life (up to 300,000 operations) and electrical life (300,000 operations), but also supports linear operating speeds from 1mm/s to 500mm/s, meeting the responsiveness and stability requirements of various charging devices. It is widely used in electric vehicle charging guns for plug-in/plug-out control, current switching, and fault detection, ensuring timely response to user operations during charging and preventing electrical faults or poor connections.

The G309 series Sealed Clamp Subminiature Micro Switch features a highly reliable sealed clip-on contact structure and is adaptable to high temperatures (-40℃ to +85℃), making it particularly suitable for environments requiring high-frequency operation, such as charging guns. Its high contact reliability and precise operation make it an indispensable component in charging pile systems. Meticulously designed by the micro switch manufacturer, the G309 series micro switches provide stable assurance for electric vehicle charging, offering solid support for the long-term development of the industry.
