Please refer to FIG. 1A . FIG. 1A is a schematic diagram illustrating a conventional keycap and balance member. As shown in FIG. 1A , the existing balance member 52 is fixed on the fixing portion 504 of the lower surface 502 of the keycap 50 .

字型外观平衡构件72便无法涵盖整个键帽70，致使当使用者按压该键帽70边缘时，如图1B中以虚线圈起的部位，仍会发生前述的倾斜不稳的现象，甚至无法完全带动键帽70的动作，致使开关无法被触发。However, with the diversification of the appearance design of the key cap, the multiplier key is not necessarily a square rectangle, but may have a trapezoidal, triangular or other polygonal appearance. Please refer to FIG. 1B . FIG. 1B is a schematic diagram of a conventional keycap and balance member. As shown in FIG. 1B , the keycap 70 has a generally trapezoidal appearance. At this time, the existing

The font appearance balance member 72 cannot cover the entire keycap 70, so that when the user presses the edge of the keycap 70, as shown in the dotted circle in FIG. Fully drive the action of the keycap 70, so that the switch cannot be triggered.
