Mechanical key-switch (keyboard switch) is one of the key parts of mechanical keyboard. Key-switch performance decides the keyboard using experience. Key’s click sound is keyboard important character. Previously, the method is to use metal plate as electric contact and it serves as sound structure as well. Due to the limitation of interior space of low-profile key-switch, metal plate elastic force is not enough, thus it always can not provide  good hand feel and clear click sound.


Mr Yu Zhengming, with TTC Team,  creatively went out of the traditional way using metal plate, and successfully developed the torsional spring independent sound structure in 2014. TTC successfully applied the China national invention patent in Dec, 2014 with patent application No. 201510203635.6.
