由該底座1與該鍵帽2的配合，使該平衡架A 31與該平衡架B 32上下兩端分別得到限位，在向下按壓該鍵帽2時，該平衡架A 31與該平衡架B 32分別作上下擺動，以獲得按壓平衡；並由該拉簧33拉動平衡架A 31與該平衡架B 32，顯著增加了按壓行程，且提高了按壓手感。 Due to the cooperation of the base 1 and the key cap 2, the upper and lower ends of the balance frame A 31 and the balance frame B 32 are respectively limited. When the key cap 2 is pressed downward, the balance frame A 31 and the balance The rack B 32 swings up and down respectively to obtain the balance of pressing; and the balance spring A 31 and the balance frame B 32 are pulled by the tension spring 33, which significantly increases the compression stroke and improves the compression feel.

在本實施例中，按鍵開關還包括一導通組件4，本實施例採用機械式的導通方式實現按鍵開關的導通與斷開功能；具體的，所述導通組件4包括插設於該底座1上的一靜片41、及插設於該底座1上且延伸至該靜片41上方的一動片42，其中，該動片42包括插設於該底座1上的一插設部421、連接於該插設部421上端部且向一側垂直彎折的一接觸部422、及連接於該接觸部422端部且向上延伸的一按壓部423；在該靜片41上端面設置有一靜觸點411，該接觸部422位於該靜片41上方，且在該接觸部422下端面設置有與該靜觸點411相對應的一動觸點4221；在所述底座1上端面向上凸設有一圍壁12，在該圍壁12內形成供該靜片41與該動片42***的一安裝槽121，該動片42的按壓部423延伸至該圍壁12上方，保證該鍵帽2在被按壓向下移動時，能接觸到該按壓部423，以達到精確的按壓導通功能。 In this embodiment, the key switch further includes a conduction component 4. In this embodiment, a mechanical conduction method is used to realize the conduction and disconnection functions of the key switch; specifically, the conduction component 4 includes a plug-in device 4.
