Product Description

The Sealed Clamp Subminiature Micro Switch G309 Series is a compact clamp subminiature micro switch widely used inside charging guns for new energy vehicles. Its primary function is to detect insertion and removal actions and ensure the safe triggering of the charging process. It operates within a temperature range of -40℃ to +85℃, maintaining stable performance even in harsh outdoor environments.

As an automotive micro switch, this sealed subminiature micro switch boasts an IP67 waterproof and dustproof rating, resisting rain, dust, and the environmental stresses of frequent insertions and removals. Its 0.1A 12VDC rating meets the signal detection requirements of the charging gun, providing accurate and reliable feedback for the entire charging interface control system.

Furthermore, this sealed subminiature micro switch offers 300,000 mechanical and electrical cycles. Its high reliability and long durability significantly extend the overall lifespan of the charging gun. Designed by a micro switch manufacturer, this product is ideal for demanding vehicle charging applications.
