Adopting a SPST-NC (Single Pole Single Throw-Normally Closed) contact arrangement, this IP67 waterproof micro switch delivers stable and consistent triggering performance even in dust, moisture, and extreme temperature environments. Designed for commercial and industrial clients, the switch integrates precision mechanical structure, reliable electrical performance, and industry-leading sealing technology, making it an ideal core component for EV charging system safety control.
With an industry-leading IP67 sealing grade, the G303 series micro switch effectively blocks the intrusion of dust and liquid, fully adapting to the outdoor installation environment of EV charging piles and vehicle-mounted charging ports. It supports an ultra-wide operating temperature range from -40℃ to +85℃, maintaining stable electrical and mechanical performance in severe cold and high-temperature working conditions, eliminating the risk of trigger failure caused by environmental changes.
This NC micro switch for EV charging ports features optimized mechanical parameters: maximum operating force of 100gf, minimum release force of 25gf, total travel of 11.00mm max, and differential movement of 2.00mm max. The precision-designed structure ensures accurate and repeatable triggering in long-term cyclic operation, avoiding false triggering or non-response, and providing reliable safety signal feedback for charging port cover opening and closing detection.
The G303 waterproof micro switch has passed ENEC, CQC, and UL international safety certifications, complying with global mainstream industrial and automotive electronic product access standards. It achieves a mechanical life of up to 500,000 cycles and an electrical life of 100,000 cycles, significantly reducing the maintenance frequency and replacement cost of end equipment for industrial clients, and ensuring long-term stable operation of the system.
