作为本发明的进一步改进，在所述基座的第二容置槽内向下凹设有一插槽，且在该插槽内凸设有一导柱，该导柱由下至上依次插入导芯从动件通槽与导芯主动件通槽中。
作为本发明的进一步改进，所述上盖的下端面设置有一插柱，该插柱下端向上开设有供导柱插入的导槽，该插柱下部具有用于插入导芯主动件通槽与弹性件内部的插入部。
作为本发明的进一步改进，所述导芯主动件侧边设置有两个凸块。
作为本发明的进一步改进，所述X型支架包括交叉设置的左平衡杆与右平衡杆，该左平衡杆的一端与右平衡杆的一端分别固定于第一容置槽内部。
作为本发明的进一步改进，还包括设置于基座上的LED指示灯。
作为本发明的进一步改进，所述导通组件包括静触片与动触片。
作为本发明的进一步改进，所述弹性件为弹簧。
本发明的有益效果为：通过增设X型支架，在键盘开关整体厚度实现薄型化的情况下，增强了键盘开关的平衡性，保证导芯组件能正常顺畅的上下移动，提高其稳定性，同时 增加按压手感，提升用户体验。
上述是发明技术方案的概述，以下结合附图与具体实施方式，对本发明做进一步说明。
附图说明
图1为本发明的爆炸图；
图2为本发明的剖面图。
具体实施方式
为更进一步阐述本发明为达到预定目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本发明的具体实施方式详细说明。
请参照图1与图2，本发明实施例提供一种超薄机械键盘开关，包括一基座1、及盖合于基座1上的上盖2，还包括分别设置于基座1上的导芯组件3、导通组件4、X型支架5与弹性件6，所述基座1上端由外至内依次开设有第一容置槽11与第二容置槽12，该X型支架5位于第一容置槽11中，该导通组件4、导芯组件3与弹性件6位于第二容置槽12中，该弹性件6套设于导通组件4下端，该导通组件4位于导芯组件3侧边。
