若将PCB板30设有若干电感31时，将该键盘开关100可设置为普通的键盘开关100和具有加速功能的键盘开关100。
普通键盘开关100：若干金属件11的长度相同，每一电感31对应一金属件11，该设置方式与一个电感31对应一金属件11的方式相同。
具有加速功能的键盘开关100：PCB板30设有若干电感31，PCB板30开设有让位孔，所述轴芯10可移动地容纳于所述让位孔，若干金属件11设于轴芯10的侧面，PCB板于邻近让位孔的表面设置电感31；每一电感31均面向轴芯10，若干金属件11的长度依次递减，若干所述金属件11远离PCB板的一端对齐设置，初始状态，每一电感31均与金属件11相隔一定距离，按压轴芯10时，若干金属件11依次靠近所述电感31，所述键盘开关100依次产生导通信号。具体地，当轴芯10向下移动一定距离时，最长的金属件11靠近一与之对应的电感31，中央检测器对该信号做出响应，PCB板70的芯片对该信号进行处理实现键入信号的输出，电脑CPU执行动作的一步，当轴芯10再向下移动一定距离，第二长的金属件11靠近一与之对应的电感31，中央检测器进一步对于该信号做出响应，PCB板70的芯片对该信号进行处理实现键入信号进一步地输出，电脑CPU执行该动作的下一步，直至设有的若干金属件11均靠近与之对应的电感31，最终电脑CPU执行完一个完整的动作。
本技术方案的键盘开关100，使得PCB板70的芯片可根据金属件110与电感31靠近的次数将原始的一个执行信号进行分级成多个信号，通过多个信号依次执行同一命令，故这样就使得执行命令的过程是一种渐进加速的过程，以带来一种渐进连贯的画面效果，更具真实感，更符合消费者的需求。
金属件11可以选用金属片，以方便安装设置，当然轴芯10还可以对应该金属片一体成型安装位，便于金属片11安装。综上，同理，可将电感31换成霍尔元件，相应地，金属件11选用磁体。
在本实施例中，所述轴芯10的每一侧面均可设有至少一所述金属件11。如将该轴芯10设置为长方体结构，故该轴芯10具有四个侧面，轴芯10的一侧面设置长度依次减小若干金属件11，另一侧面也可以设置长度继续依次减小的若干金属件11，直至每一侧面都设置有金属件11，以使得加速分级可以更多。
进一步地，确定轴芯10状态为正常工作位置状态，为了便于手指操作，在所述轴芯10上端可拆卸连接有键帽（未标示），所述键帽下表面凹设有异型槽，异型槽的底壁凹设有插孔，所述轴芯10的上端面凸设有凸柱，所述凸柱插设于所述插孔。如此设置，使得光电机械开关100单元的整体高度降低，还能使光电机械开关100制作的更加小巧，节省可利用空间，使得键盘可做的更薄，通过键帽的异型槽结构，还可阻挡大部分的灰尘或水雾。其中，键帽的外表面优选为曲面，并采用人体工程学设计，使手指敲击在键帽时，接触感增强，不突兀。
进一步地，该键盘开光100还可设置背光灯70，该背光灯与所述PCB板30电性连接。
其中，所述背光灯70优选RGB型的LED灯，由于键帽上端面一般设有便于操作的字符，背光灯70透过键帽可使字符发光，当选用RGB型的LED灯时，字符的光线更加丰富多彩，还可以将背光灯70设置为按一定规律闪动等，更加炫酷。
进一步地，所述键盘开关100还设有平衡弹性支架90，所述平衡弹性支架90一端抵接轴芯10，另一端抵接PCB板30。当应用于笔记本电脑时，且设置为一电感31和一金属件11的方式时，参照图4，可将笔记本电脑的键帽和轴芯10设置为一体，轴芯10面向PCB板30的一端设有一金属件11，平衡弹性支架90对应该金属件11设有通孔，所述平衡弹性支架90一端抵接轴芯10，另一端抵接PCB板30，PCB板30设有电感31，金属件11与电感31通过通孔相互面对，初始状态，金属件11与电感31相隔一定距离，按压轴芯10时X型的平衡弹性支架90向下移动，且伸展，金属件11靠近电感31，键盘开关100产生信号。通过设置平衡弹性支架90使得按压手感更佳，且使电脑可实现超薄。
当然，键盘开关100还包括弹性件51和安装座50，所述安装座50开设有安装孔，弹性件51和至少部分所述轴芯10容纳于所述安装孔，所述弹性件51的一端设于所述安装座50，另一端抵接所述轴芯10。
其中，弹性件30优选为弹簧，当然还可以为弹性金属片、空气弹簧等；
当第一弹性件30为弹簧时，优选的结构有：通过轴芯10固定弹簧，即轴芯10下端设有容置槽，容置槽的底壁凸设有凸台，弹簧30的一端套入凸台与容置槽的底壁抵接，还可以通过安装座50固定弹簧，安装座50朝向中心的表面设有容置槽，该容置槽的槽壁凸设有柱体，弹簧30套入柱体中且与安装座50的容置槽的槽壁抵持，当然还可以通过轴芯10和安装座50同时固定弹簧的位置，使得按压轴芯10时该弹簧30不会发生偏移，防止了误操作。
进一步地，安装座50与PCB板30的固定安装方式列举两实施例：
第一实施例：安装座50的两侧均设有至少一卡扣52，PCB板30开设有让位孔，所述安装座50贯穿所述让位孔，所述卡扣52卡持于所述让位孔的周缘。
第二实施例：参照图1，PCB板30设有两通孔，具体地，可以在PCB板30的两侧对称设置该长条形的通孔，安装座50远离轴芯10一端的两侧均设有至少一卡扣52，每一所述卡扣52均贯穿一通孔，且卡持于所述第二表面34。当安装座50为方形时，卡扣优选为设置四个，即可固定稳固。
本发明还提出一种键盘，该键盘包括键盘开关100，该键盘开关100的具体结构参照上述实施例，由于本键盘采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
其中，该键盘可以为普通配件键盘，也可以为笔记本电脑键盘等。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
