在底板上布设LED灯后，LED发光提供光源，这样就构成了背光键盘结构。
优选的，底板上开设剪刀脚固定孔，该剪刀脚固定孔可以为直通孔或阶梯孔。
剪刀脚的底部通过固定件固定到该剪刀脚固定孔内，优选的，固定件为塑胶件，此时可以通过注塑工艺将塑胶件注塑到剪刀脚固定孔内固定成型；也可以在塑胶件底部设有热熔柱，该热熔柱通过热熔工艺固定到剪刀脚固定孔内。
本实用新型的底板可以为PCB板，其中，PCB板又称为印刷电路板，也可以选用金属板、PC板(即聚碳酸酯板)或者玻纤板等。另外，弹性体优选为硅胶或金属弹片。

具体实施方式
下面结合附图对本发明的技术方案作进一步说明。
本发明的键盘结构，包括底板1、剪刀脚2、弹性体3和键帽4，如图6所示，其中，底板1为PCB板(即印刷线路板)，也可以选用金属板、PC板或者玻纤板等；剪刀脚2由一个外剪刀脚201和一个内剪刀脚202交叉组成，其中，外剪刀脚201和内剪刀脚202均为方框结构，将它们固定在底板1和键帽4之间。在键帽4底部设有卡槽，外剪刀脚201和内剪刀脚202的顶部卡在该卡槽内。底板1上开设剪刀脚固定孔101，该剪刀脚固定孔101可以是直通孔，如图1和图3所示，也可以是阶梯孔，如图2和图4所示。外剪刀脚201和内剪刀脚202的底部通过固定件102固定到该剪刀脚固定孔101内，固定件102选用塑胶件，此时的固定方式有两种，第一种是通过注塑工艺将塑胶件注塑到剪刀脚固定孔101内固定成型，第二种是在塑胶件底部设有热熔柱103，热熔柱103通过热熔工艺固定到剪刀脚固定孔101内，如图3-4所示。
本发明的弹性体3可以是硅胶，也可以是金属弹片，弹性体3由一对分别与底板和键帽连接的下支撑301和上支撑302组成，其中，上下支撑为槽型结构，槽型结构包括横部303和两侧的支脚304，上下支撑的横部303连接在一起，上支撑302的支脚304向上延伸与键帽4底部固定，下支撑301的支脚304向下延伸与底板固定。导通柱305固定在下支撑301横部303的下方，悬空在底板1的上方，一般情况下不会与底板1接触，按压键帽后，导通柱305向底板方向移动，通过接触底板上的线路来实现线路导通。
本发明在底板上通过蚀刻、印刷等工艺布设线路5，在弹性体3导通柱305对应的底板位置上布设线路的正负极接触点，当导通柱305接触该正负极接触点时线路接通，当导通柱305离开正负极接触点时线路断开。
另外，本发明可以在底板1上焊接发光二极管6，即LED灯，放灯数量和位置根据实际情况确定，通过LED发光提供光源，这样就构成了背光键盘结构，如图5所示。
工作过程：向下按压键帽，键帽压缩弹性体向底板方向移动，弹性体的导通柱接触到底板上的线路时，线路接通；放开键帽后，键帽在弹性体的反弹作用下向底板反方向移动，导通柱离开底板，线路断开。
