发明名称 Key switch assembly for a computer keyboard
摘要 A key switch assembly includes a key cap support with first and second support levers. The first support lever has upper rods, lower rods and intermediate circular connecting portions. The circular connecting portions have circumferential edges which form first shoulders that interconnect front sides of the upper and lower rods, and second shoulders that interconnect back sides of the upper and lower rods. The lower rods and upper rods have concave first and second end faces that extend transversely along the circumferential edges. The second support lever has upper arms, lower arms and intermediate circular plates. The circular plates have peripheral edges which form third shoulders that interconnect back sides of the upper and lower arms, and fourth shoulders that interconnect front sides of the upper and lower arms. The upper and lower arms have concave third and fourth end faces that extend transversely along the peripheral edges of the circular plates. The first and second shoulders abut slidably against the third and fourth end faces, and the first and second end faces abut slidably against the third and fourth shoulders, thereby coupling rotatably the first and second support levers.
