With the popularity of mechanical keyboards, most game players have more than one mechanical keyboard in their hands. Many advanced players are not satisfied with the existing unchanging mechanical axis feel, and have higher and higher requirements for the mechanical axis experience. TTC has launched the second-generation gold shaft. While maintaining the characteristics of the mechanical shaft, it greatly improves the smoothness of key operation and reduces the noise generated during the operation, thereby improving the user experience.

At the same time, using expensive 24k gold contacts:

After rigorous screening and testing of a variety of materials, TTC found that 24K gold is currently the most ideal material for making switch contacts. Gold is the most ductile and malleable metal, with high conductivity, high oxidation resistance and resistance to environmental corrosion (including resistance to other non-chlorine acids). Therefore, the application of gold to high-humidity, highly corrosive atmospheric electronic contact, and high failure rate contact point equipment has an irreplaceable role.

After research and development, design and application, the shaft body can not only support the user's high frequency use of the keyboard shaft body after using the gold contacts, but also has a more sensitive and reliable response than other contact shaft switches.

Good steel is used on the blade

Innovation is the foundation of TTC, and it is TTC's insatiable fanatical pursuit of products. In the process of R&D and design of the gold contact and gold structure of the shaft body, the test and screening of the internal spring structure materials of the shaft body are also being carried out, and finally it is decided to customize the latest spring material technology of NIPPON SEISEN Co., Ltd. of Japan. After testing, the spring made of this material has a good rebound effect, and the spring has very good fatigue resistance, which can greatly extend the stability of the shaft life and the freshness of the hand.
