键盘开关，顾名思义是一种应用并安装于键盘上的开关，这种开关的主要结构包括有基座、上盖、静触片、动触片和按钮件，该上盖和基座围合形成容置腔，该静触片、动触片和按钮件设置于该容置腔中，且该按钮件的一端露出容置腔外，通过按压操控按钮件，使得按钮件上下活动，进而通过按钮件作用于动触片上，使得动触片与静触片接触连接或脱离分开。
传统的键盘开关在操作过程中使用者无法直观地判断该按键开关开启/关闭状态，故使用者操作时会倍增困扰。目前，市面上出现了一些带灯的键盘开关，其一般是将采用单色的LED灯，如此使得发出的灯光颜色单一，不能满足使用者的使用要求。
发明内容
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种侧边全彩发光的键盘开关，其能有效解决现有之带灯键盘开关发光色彩单一的问题。
为实现上述目的，本发明采用如下之技术方案：
一种侧边全彩发光的键盘开关，包括有底座、静触片、动触片、上盖以及用于控制动触片与静触片接触或分离的按键；该静触片和动触片均设置于底座上，该静触片的焊接脚和动触片的焊接脚均伸出底座外；该上盖安装于底座上；该按键设置于底座上并露出上盖，针对该按键设置有复位弹簧，该底座的一侧边固设有一全彩LED灯，对应的该上盖的侧边开设有让位通槽，该全彩LED灯的灯***于该让位通槽中，该全彩LED灯的导电脚伸出底座外。
作为一种优选方案，所述底座上设置有凹位，该导电脚位于该凹位中，该导电脚的尾端穿过凹位的底部向下伸出底座外。

作为一种优选方案，所述底座的侧缘向上延伸出有第一定位块，对应地该上盖的内侧壁设置第一定位槽，该第一定位块嵌于该第一定位槽中。
作为一种优选方案，所述第一定位块的内侧面设置有导引槽，对应地该按键的外侧面设置有导引块，该导引块位于该导引槽中并沿导引槽上下活动。
作为一种优选方案，所述按键向下延伸出有导引柱，对应地该底座上设置有导引孔，该导引柱嵌于该导引孔中并沿导引孔上下活动。
作为一种优选方案，所述上盖与底座之间通过扣部和扣孔彼此扣合安装连接一起。
作为一种优选方案，所述上盖的两相对侧面下端均间隔设置有两前述扣孔，对应地该底座的两相对侧面上端均间隔向外凸设有两前述扣部。
作为一种优选方案，所述上盖的上方设置有一键帽，该键帽覆盖住该全彩LED灯，且该全彩LED灯位于键帽的一侧边内，该键帽与按键连接并带动按键来回活动。

具体实施方式
请参照图1至图7所示，其显示出了本发明之较佳实施例的具体结构，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。
该按键50设置于底座10上并露出上盖，针对该按键50设置有复位弹簧60，以及，该底座10的一侧边固设有一全彩LED灯70，对应的该上盖40的侧边开设有让位通槽41，该全彩LED灯70的灯体71位于该让位通槽41中，该全彩LED灯70的导电脚72伸出底座10外；该底座10上设置有凹位11，该导电脚72位于该凹位11中，该导电脚72的尾端穿过凹位11的底部向下伸出底座10外；并且，该导电脚72为并排间隔设置的四个，该四个导电脚72均向下伸出底座10外。
该底座10的侧缘向上延伸出有第一定位块12，对应地该上盖40的内侧壁设置第一定位槽42，该第一定位块12嵌于该第一定位槽42中，在本实施例中，该底座10的两相对侧缘均设置有前述第一定位块12；并且，该第一定位块12的内侧面设置有导引槽13，对应地该按键50的外侧面向外凸设有导引块51，该导引块51位于该导引槽13中并沿导引槽13上下活动；另外，该按键50向下延伸出有导引柱52，对应地该底座10上设置有导引孔14，该导引柱52嵌于该导引孔14中并沿导引孔14上下活动。
此外，该上盖40的上方设置有一键帽80，该键帽80覆盖住该全彩LED灯70，且该全彩LED灯70位于键帽80的一侧边内，该键帽80与按键50连接并带动按键50来回活动；具体而说，该按键50具有连接块53，该连接块53呈十字型，对应地该键帽80上设置有嵌置槽81，该嵌置槽81亦呈十字型，该连接块53紧配合嵌于该嵌置槽81中。
详述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的侧边上，使得各个导电脚72穿过凹位11向下伸出底座10外；然后，将复位弹簧60套装于导引柱52外，使得复位弹簧60的下端嵌入底座10中；接着，将按键50的上端由下往上穿过上盖40，使该导引块51对准导引槽13而嵌入，该第一定位块12对准第一定位槽42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，同时该复位弹簧60的上端嵌入按键50，使得复位弹簧60抵推于底座10和按键50之间，并且该灯体71位于让位通槽41中；然后，将键帽80的嵌置槽81套入按键50的连接块53，实现键帽80与按键50的连接固定即可。
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发出的光从透过让位通槽41射向键帽80的侧缘并使得键帽80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80上使得键帽80下压时，该按键50随键帽80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80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，该动触点31与静触点21再次分离而断开电路。
本发明的设计重点在于：通过采用全彩LED灯，将该全彩LED灯设于底座的一侧边，并配合上盖的侧边开设有让位通槽，利用全彩LED灯的灯光透过该让位通槽向外射出，取代了传统之采用单色LED灯的方式，本发明利用了全彩LED灯具有色彩均匀、亮度高等优点，使得产品的灯光七彩效果更好，并实现全彩色发光，从而满足使用者的使用要求。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故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、等同变化与修饰，均仍属于本发明技术方案的范围内。
