背景技术
机械键盘是一种键盘的类型，从结构来说，机械键盘的每一颗按键都有一个单独的开关来控制闭合，这个开关也被称为“轴”，依照开关的分类，机械键盘可分为茶轴、青轴、白轴、黑轴以及红轴。正是由于每一个按键都包含一个独立的开关组成，因此按键段落感较强，从而产生适于游戏娱乐的特殊手感，故而通常作为比较昂贵的高端游戏外设，亦是程序员的理想设备。

当键帽30被按压时，主弹簧50和副弹簧60被压缩，摆臂41从所述第一滑槽依次滑入所述第二滑槽和所述第三滑槽，同时带动偏转体40沿正方向旋转；当摆臂41滑入所述第三滑槽时，摆臂41与撞击槽13相对，副弹簧60复位，使得摆臂41瞬间下移并撞击撞击槽13的槽壁上端；同时，第一通光槽12与所述第二通光槽错开，使得光电开关21的光路被阻断；
当键帽30从按压状态被松开时，主弹簧50将键帽30弹起；两摆臂41分别沿所述第三滑槽依次滑入所述第二滑槽和所述第一滑槽，使得摆臂41脱离撞击槽13，并带动偏转体40沿反方向旋转；摆臂41重新架设于环形锁定件11的上边缘；光电开关21的光路为恢复为通路。
对本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及形变，而所有的这些改变以及形变都应该属于本实用新型权利要求的保护范围之内。
