Abstract: A signal input module includes: a key body; a key base coupled to a lower portion of the key body, and having fixing portions of different heights at both sides thereof; a flexible printed circuit board disposed such that an upper surface thereof is covered by the key base, and having a dome portion on a rear surface thereof, the dome portion configured to generate a signal when pressed by the key base; and a light emitting portion formed on one surface of the flexible printed circuit board, wherein the fixing portion and the key base are connected to each other by a connection portion, wherein the connection portion is bent from one end of the key base, extends toward the fixing portion, wherein the connection portion is provided with a hole, and wherein the flexible printed circuit board is disposed to cross the hole. Under such configuration, the number of components can be reduced and the signal input module can have a slim configuration.

Abstract translation: 信号输入模块包括：一个键体; 键体，其与键体的下部连结，并且具有两侧的不同高度的固定部; 柔性印刷电路板，其上表面被所述键座覆盖，并且在其后表面上具有穹顶部，所述穹顶部被配置为当由所述键座按压时产生信号; 以及形成在所述柔性印刷电路板的一个表面上的发光部，其中，所述固定部和所述键座通过连接部彼此连接，所述连接部从所述键基的一端弯曲，朝向 所述固定部分，其中所述连接部分设置有孔，并且其中所述柔性印刷电路板设置成穿过所述孔。 在这种配置下，可以减少组件的数量，并且信号输入模块可以具有纤薄的配置。
