WIPO Patent Application WO/2018/188485

A1

Disclosed is an ultra-thin key switch having high balance, comprising a base, wherein an accommodating cavity is provided on an upper surface of the base, and a conduction assembly is arranged in the accommodating cavity. Further comprised are a guiding core arranged on the base, and an X-type balancing rack encircling the outside of the guiding core, wherein a lower end of the guiding core is connected to the base via a spring. The X-type balancing rack is mainly formed by intersecting a balancing rod A and a balancing rod B, wherein both the balancing rod A and the balancing rod B are enclosed frame structures, and the X-type balancing rack is an enclosed-type structure overall. After intersection of the balancing rod A and the balancing rod B, two intersection points are formed. The X-type balancing rack is divided into a lower embedded part and an upper swing part by the two intersection points, and a positioning clamp block is arranged at an end portion of the lower embedded part. A plurality of upper guiding blocks are inwardly arranged in a protruding manner at an inner side edge of the upper swing part, and a plurality of upper guiding shafts are arranged in a protruding manner at an outer side edge of the guiding core and right below the upper guiding blocks. In a pressing process, the key switch of this invention has better balance effect and stronger stability, and the overall stability is improved.
