请参照图1至图8所示，其显示出了本实用新型之两种较佳实施例的具体结构，在此，两种实施例中均以中心全彩发光的键盘开关（无声型和有声型）为例作说明，该键盘开关的整体厚度能够做得比较薄，所占用体积小，其组装结构简单且稳固、操作性能稳定可靠、使用者操作舒适度佳，也有利于键盘的微型化设计及制作。
如图1至5所示，其显示了第一种实施例的大致结构，其为无声型的中心全彩发光的键盘开关，其包括有底座10、静触片20、动触片30、上盖40以及用于控制动触片30与静触片20接触或分离的按键50′。其中，该静触片20和动触片30均设置于底座10上，该静触片20上设置有静触点21，对应地该动触片30上设置有动触点31，该静触片20的焊接脚22和动触片30的焊接脚32均伸出底座10外。
该上盖40安装于底座10上，在本实施例中，该上盖40与底座10之间通过扣部101和扣孔102彼此扣合安装连接一起，具体而说，该上盖40的两相对侧面下端均间隔设置有两前述扣孔102，对应地该底座10的两相对侧面上端均间隔向外凸设有两前述扣部101，该四个扣部101与对应的扣孔102扣合固定连接。
如图1、2及3所示，该按键50′设置于底座10上并露出上盖40，针对该按键50′设置有复位弹簧60；该上盖40的上方设置有一键帽（图中未示出），该键帽与按键50′连接并带动按键50′来回活动。该按键50′的上段位置设置有用于与外接配件（例如上述键帽）连接的连接部54′，该连接部54′内开设有上端开口的安装槽541′，该安装槽541′内侧壁面上间距式凹设有四个紧配嵌装槽542′，该紧配嵌装槽542′具有供外接配件嵌入的上端开口，且该紧配嵌装槽542′的内侧壁上凸设有用于加强连接稳固性的凸筋543′,且该凸筋543′沿上下方向延伸设置。
如图2和图4所示，所述四个紧配嵌装槽542′均布于安装槽541′的周缘，该紧配嵌装槽542′具有与安装槽541′相对的第一内壁面及连接于第一内壁面两侧的第二、三内壁面，该第二、三内壁面为两对侧面，前述凸筋543′分别设置于第二、三内壁面上，其相应的凸筋543′也彼此相对设置。于实施例中，安装槽541′为圆形通槽，前述连接部54′则为方形结构，前述四个紧配嵌装槽542′对应连接部的四个顶点布置，其紧配嵌装槽542′大致呈方形结构，前述凸筋543′位于紧配嵌装槽542′的第二、三内壁面的中间或靠近中间位置，从而，使得键帽与按键50′间连接稳固且力度分布均匀，不易出现键帽松动等不良现象。组装也十分方便，直接将键帽对应前述安装槽541′及紧配嵌装槽542′向下嵌入即可。
以及，该底座10的中心位置上设置有插件式LED灯(全彩LED灯)70，该按键50′的轴向中心开设有通孔51，且该通孔向上与前述安装槽相通且彼此上下位置相对，该全彩LED灯70的灯光透过该通孔51及安装槽向外射出。该底座10的中心向上凸设有用于导引按键50′上下活动的导柱11，该导柱11与该通孔51相适配并由下往上插装在通孔51中，前述全彩LED灯70安装于该导柱11内。
该种无声型的按键开关，其按键50′包括有一体成型连接的按键主体，前述通孔轴向贯通式设置于该按键主体内，前述连接部54′设置于按键主体上端部位；前述复位弹簧60的上端抵于按键主体上，并其下端抵于前述底座10上；该按键主体侧面设置有用于抵推前述动触片30的抵推凸部52′，并其外侧面凸设有导引块51′，相应地，前述底座10的内侧面设置有导引槽12，该导引块51′位于导引槽12中并沿导引槽12上下活动。
该全彩LED灯70包括有灯体71和连接于灯体71且自灯体71上间隔伸出的四个导电脚，位于中间位置的两个导电脚上分别形成有弯折部7201，其弯折部7201一端连接有用于与灯体71连接的连接部7202，并其另一端连接有焊接部7203，且该中间位置的两个导电脚的焊接部7203分别位于连接部7202的两侧。
所述四个导电脚自灯体71下端面并排向下伸出，为便于说明，在此将前述四个导电脚依次定义为第一、二、三及四导电脚（图号分别为72、73、74、75）；该第二导电脚73的弯折部7201自其连接部7202的末端向左侧弯折再朝下弯折而成，该第二导电脚73的焊接部7203一体连接于相应弯折部7201的下端缘并向下延伸设置；该第三导电脚74的弯折部7201自其连接部7202的末端向右侧弯折再朝下弯折而成，该第三导电脚74的焊接部7203一体连接于相应弯折部7201的下端缘并向下延伸设置。
所述第一、四导电脚（72、75）均一体竖向延伸设置，第一、二、三及四导电脚自灯体71的伸出始端位于同一直线上，第一、二、三及四导电脚的延伸末端分别位于四边形的四个顶点上（如图7所示），相比并排设置的间距，弯折后该四个导电脚的各焊接部间距增大了许多，避免了焊接时导电脚间出现短接的现象，焊接时也更为方便、快捷；如此，通过弯折部这种简单巧妙的改进方式及结构，不用额外增加过多成本，获得了很好的效果，提高了焊接质量及效率。
结合图2、图3及图5(a)和图5(b)所示，所述导柱11顶端设置有安装腔111，前述灯体71位于安装腔111内，所述灯体71外侧凸设有定位凸部711，相应地，前述安装腔111内侧壁上设置有定位凹槽112，该定位凸部711配合于定位凹槽112内，前述四个导电脚（72、73、74及75）向下伸出底座10外。以及，本实施例中的灯体71为圆形结构，其四个导电脚（72、73、74及75）自灯体71的伸出始端均布式位于相应直径上。
使用时，该全彩LED灯70处于常亮状态或者可随静触片20与动触片30接触或导通而发生变化，该全彩LED灯70发出的光从透过通孔51射向键帽的中心并使得键帽通体发光。原始状态下，该按键50′抵住动触片30使得动触片30的动触点31与静触片20上的静触点21保持分离，此时的电路处于断开状态，当作用力作用在键帽上使得键帽下压时，该按键50′随键帽下压活动，该按键50′脱离对动触片30的抵压，动触片30在自身弹力的作用下张开而使得动触点31与静触点21接触，从而导通电路；当松开键帽时，该按键50′在复位弹簧60的作用下自动向上复位，使得按键50′再次抵压住动触片30（利用抵推凸部52′抵压动触片30），该动触点31与静触点21再次分离而断开电路。
接着，请参见图6(a)至图8所示，其显示了第二种实施例的大致结构，其为有声型的中心全彩发光的键盘开关；其大部分结构与上述第一种实施例相同，主要不同点在于按键结构不同，大致体现如下：
该按键50包括有导芯51和与导芯51配合的导芯从动件52，前述复位弹簧60一端抵于该导芯51上，并其另一端抵于底座10上；该导芯51与导芯从动件52彼此相对可滑动式设置，且导芯51与导芯从动件52上分别配合式设置有用于防止其两者分离的第一限位部515、第二限位部523，该第一限位部515、第二限位部523随导芯51的滑动而彼此接触抵压或分离；该导芯51上设置有第一发声部516，该导芯从动件52上设置有与第一发声部516配合碰撞产生声音的第二发声部524，
该第一发声部516、第二发声部524随导芯51的下压滑动而彼此碰撞抵压，该第一发声部516、第二发声部524随导芯51的向上复位滑动而彼此分离。
具体而言，所述导芯从动件52中间具有贯通其上下端面的容置腔521，前述第二限位部523设置于该容置腔521内壁，前述导芯51下段伸入该容置腔523内。
所述导芯51包括有一体连接的上段连接部511和下段连接部512，该下段连接部512内开设有竖向延伸的套接孔513（该套接孔513向上贯通导芯51上端，即前述通孔。），前述底座10上朝上凸设有用于导引导芯51上下活动的导柱11，该导柱11与套接孔513相适配并由下往上插装在套接孔513中；该上段连接部511下端面向下延伸形成有弹性限位臂514（本实施例中，于下段连接部512两侧各设置有一弹性限位臂514），前述第一限位部515自弹性限位臂514的自由端弯折延伸而成，该第一限位部515位于第二限位部523下方，复位弹簧60套设于导柱11和导芯51的下段连接部512外围，且复位弹簧60夹设于弹性限位臂514与下段连接部512之间。
对应前述第一限位部515位置，于导芯从动件52的容置腔521内壁面上径向往外凹设有限位凹槽522，前述第二限位部515形成于该限位凹槽522的上端面；以及，所述导芯从动件52上对应限位凹槽522处，形成有便于第一限位部515从导芯从动件52上端开口处进入限位凹槽522内的导引面528；而前述第一限位部515有弹性限位臂514的弹性作用下，可上下滑动式伸入限位凹槽522，前述弹性限位臂514的弹性作用使得第一限位部515保持位于较佳的配合位置内，确保了导芯51与导芯从动件52的配合可靠性及该键盘开关的性能稳定。
所述导芯51的上段连接部511上径向往外延伸形成有第三限位部517，相应地，前述上盖40上形成有与第三限位部517配合的第四限位部41，该第三限位部517位于第四限位部41下方，且该第三限位部517随导芯的滑动而与第四限位部41向上接触抵压或向下分离；从图3及图4可以看出，其于上盖内壁面凹设有凹槽，前述第四限位部41即该凹槽的上端面，如此，前述第三限位部517则一直位于凹槽内，该凹槽对第三限位部517而言，还起到一个导引和限位的作用。
所述导芯从动件52的外侧面凸设有导引块53（于两对侧各设置有一个），相应地，前述底座10的内侧面设置有导引槽12，该导引块53位于导引槽512中并沿导引槽512上下活动；前述限位凹槽522设置于该导引块53的背侧，合理利用了空间。
导芯从动件52外侧凸设有用于抵推前述动触片30的抵推凸部525，该抵推凸部525上设置有利于保持对动触片30的抵推的凹位5252，以及，所述抵推凸部525上设置有便于向下推入的导引面5251，该导引面5251位于凹位5252上方，且凹位5252与导引面5251之间连接有过渡弧面5253，如此，保证了键盘开关的操作顺畅度及控制准确度，提高了键盘开关的工作性能。
简单介绍本实施例的组装过程和使用方法如下：
组装时，首先，将静触片20和动触片30安装于底座10上，使得静触片20的焊接脚22和动触片30的焊接脚32均向下伸出底座10；接着，将全彩LED灯70组装于底座10上，使得全彩LED灯70的灯体71固定于导柱11之顶端的凹位111内，该各个导电脚72向下伸出底座10外；然后，将复位弹簧60套装于导柱11外，使得复位弹簧60的下端嵌入底座10内的相应定位槽中；接着，将导芯51组装入导芯从动件52内形成按键50，按键50的上端由下往上穿过上盖40，使该导引块53对准导引槽14而嵌入，并使扣部101与扣孔102扣合，此时，该上盖40安装固定于底座10上，同时使得复位弹簧60抵推于底座10和按键50之间，最后，安装键帽，完成组装。
使用时，该全彩LED灯70处于常亮状态或者可随静触片20与动触片30接触或导通而发生变化，该全彩LED灯70发出的光从透过通孔51射向键帽的中心并使得键帽通体发光。原始状态下，该按键50抵住动触片30使得动触片30的动触点31与静触片20上的静触点21保持分离，此时的电路处于断开状态，当作用力作用在键帽上使得键帽下压时，导芯51上的第一发声部516与导芯从动件52上的第二发声部524随导芯51的下压滑动而彼此碰撞发出声音，这样，使用者在敲击时键盘开关能够发出声音，使用者操作时获得更佳的手感，也便于使用者能够清晰感知自己操作时的敲击状态；随即，导芯从动件52于导芯51的抵推作用下一同向下滑动；该按键50脱离对动触片30的抵压，动触片30在自身弹力的作用下张开而使得动触点31与静触点21接触，从而导通电路；当松开手后，该第一发声部516、第二发声部524随导芯51的向上复位滑动而彼此分离，然后，第一限位部515向上抵压于第二限位部523上以带动导芯从动件52一同向上复位，使得按键50再次抵压住动触片30，该动触点31与静触点21再次分离而断开电路。
本实用新型的设计重点在于，主要系通过前述底座、静触片、动触片、上盖、LED灯、按键及复位弹簧的设计及组装配合，使得该种键盘开关整体厚度能够做得比较薄，所占用体积小，其组装结构简单且稳固、操作性能稳定可靠、使用者操作舒适度佳，也有利于键盘的微型化设计及制作；尤其是，其按键上设置的安装槽、紧配嵌装槽及凸筋，有效加强发键帽与按键间连接稳固度，使用时不会出现松动等不良现象，保证了键盘开关的使用性能的稳定；将LED灯的导电脚进行弯折结构设计，增大了各导电脚的焊接部之间的间距，避免了焊接时导电脚间出现短接的现象；提高了产品组装效率及加工质量。
以上所述，仅是本实用新型的较佳实施例而已，并非对本实用新型的技术范围作任何限制，故凡是依据本实用新型的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本实用新型技术方案的范围内。
