摘要： A to-be-depressed member includes an elastic dome. A sectional shape of the dome orthogonal to an axis line (X2) of the dome is line-symmetric about a symmetry axis (Ax). The dome has a three-dimensional shape that is symmetric with respect to a virtual plane (Sx) containing the symmetry axis and the axis line. During a swinging movement responsive to a depressing operation, an opposed surface of an opposed member relatively approaches and contacts a distal end of the dome to deform the dome so as to generate a reactive force. As for an angle defined between the axis line of the dome and a normal line (X1) of the opposed surface, the angle (θ0) in an initial state falls in a range from a first angle variation amount from the initial state to a first-contact state to a second angle variation amount from the initial state to a depression-completed state.

摘要： An electroluminescent keyboard includes a plurality of membrane switch structures, a plurality of keycaps, a plurality of electroluminescent elastic members, and an electrode layer. The electroluminescent elastic members are arranged between the keycaps and respective membrane switch structures for emitting light in response to an electric current or an electric field. The electrode layer is arranged between the electroluminescent elastic members and respective membrane switch structures and electrically connected to respective electroluminescent elastic members. The electroluminescent elastic members emit light when the electric current passes through the electrode layer or the strong electric field is applied to the electrode layer. The light-emitting element and the backlight module that are used in the conventional keyboard are not included in the electroluminescent keyboard. In addition, the light could be effectively controlled to be guided to a desired luminous region of the keycap. As a consequence, the illuminated keyboard is very cost-effective.

摘要翻译： 电致发光键盘包括多个膜开关结构，多个键帽，多个电致发光弹性构件和电极层。 电致发光弹性构件设置在键帽和各个薄膜开关结构之间，用于响应于电流或电场发光。 电极层设置在电致发光弹性部件和各个薄膜开关结构之间，与各个电致发光弹性部件电连接。 电致发光弹性体在电流通过电极层时发光，或者强电场施加到电极层。 在常规键盘中使用的发光元件和背光模块不包括在电致发光键盘中。 此外，可以有效地控制光被引导到键帽的期望的发光区域。 因此，照明键盘是非常划算的。
