与按压声音可调的按键不同的是，本实施例的按键在开关轴1侧壁去除了铲机502，使得手感件7移动时始终保持直上直下，手感件7优选为设置在开关轴1侧壁的手感扭簧701，所述壳体4内壁还设有一台阶部401，手感扭簧701的中段在不受力状态下抵接于台阶部401；当摆臂605正对手感扭簧701的力臂时，按压开关轴1下行会受到来自于摆臂605对手感扭簧701的的阻力进而增加按压所需的力度，给用户提供一种按压力度强的手感。
按键的切换器6包括有装设有磁铁601的摆盘602以及与PCB板电连接的线圈模组603，所述摆盘602设置于线圈模组603内且能够于线圈模组603内转动，所述摆盘602与摆臂605连接，当线圈模组603驱动磁铁601转动时，摆盘602带动摆臂605移动，使摆臂605正对或远离手感件7。

本实施例的按键还具有输出电气信号的功能，作为光电按键时，静音垫9或开关轴1底部设有光栅件903，电气元件为贴设于PCB板上的光对管组件11，光栅件903能够切换光对管组件11之间的光路径从而输出不同的光电信号。
作为电磁按键时，静音垫9或开关轴1底部设有磁性件904，电气元件为贴设于PCB板上的霍尔元件12，磁性件904能够切换霍尔元件12接收到的磁通量从而输出不同的电磁信号，图2示出霍尔元件贴片与PCB板上的位置关系。

需要说明的是，本申请中不论发声件中的发声蓄力扭簧还是手感件的手感扭簧，都可以换成簧片或其它能够弹性形变的物件，这一类物件皆属于本申请中的扭簧的等同替换。
以上，仅为本发明的较佳实施例，并不用以限制本发明，凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同替换和改进，均应包含在本发明技术方案的保护范围之内。
