| description | A key structure comprises a bottom plate, a membrane switch circuit, a key cap and a balance rod. The bottom plate comprises a mounting part. And the membrane switch circuit is arranged on the bottom plate. And the key cap is arranged above the membrane switch circuit. The balance rod is arranged between the bottom plate and the key cap. The balance rod comprises a rod body and a first rod part, the rod body is connected with the key cap, and the first rod part is pivoted corresponding to the installation part and is connected with the bottom plate. A light-proof area is arranged in the overlapping range of the vertical projection of the thin-film switch circuit and the vertical projection of the key cap.
一种按键结构，包括一底板、一薄膜开关电路、一键帽以及一平衡杆。底板包括一装设部。薄膜开关电路设置于底板上。键帽设置于薄膜开关电路的上方。平衡杆设置于底板与键帽之间。平衡杆包括一杆体及一第一杆部，杆体连接键帽，第一杆部对应装设部枢接设置而与底板相连接。薄膜开关电路与键帽的垂直投影的重叠范围内具有一不透光区域。 |
