G303-130S05A1U
Yutai
The G3 Sealed Micro Switch (model: G303-130S05A1U) is a high-reliability snap-action circuit control component developed and manufactured by Yutai Electronics. This sealed miniature micro switch with a round handle is engineered to deliver stable on-off control with minimal actuation force, featuring an integrated IP67 sealed structure to adapt to dust-prone, humid, and space-constrained working environments. Fully compliant with international safety standards, it is a trusted circuit control solution for equipment manufacturers, brand owners, and bulk procurement clients worldwide.
The round handle of the G3 Sealed Micro Switch matches the fully sealed housing, effectively protecting internal contact components from dust and moisture intrusion, with a switch sealing grade up to IP67. Its ultra-compact miniature size fits perfectly into the narrow installation spaces of small and medium-sized equipment, fully meeting the miniaturization design needs of modern electronic products.
This sealed micro switch operates stably in an ultra-wide temperature range of -40℃ to +85℃. It maintains consistent actuation force and contact performance in indoor, outdoor, and vehicle-mounted scenarios, without malfunction caused by extreme temperature fluctuations, ensuring reliable operation in harsh working conditions.
Under rated working conditions, the G3 Sealed Micro Switch delivers up to 500,000 cycles of mechanical life and 100,000 cycles of electrical life. Its high-precision internal structure greatly reduces mechanical wear during repeated operations, effectively lowering equipment failure rate and after-sales maintenance costs for commercial clients.
The product has obtained ENEC, CQC, and UL certifications, complying with global electronic component safety standards and meeting the import and export requirements of mainstream markets in North America, Europe, and Southeast Asia. It supports both AC and DC circuit control, covering 0.1A 125/250VAC, 48VDC, and 3A 12VDC rated loads, adapting to both low-power signal control and low-voltage power control circuit designs.
