As shown in Fig. 3, when the pressing portion 2 〇 1 is subjected to a downward external force, the movable member 2 is moved from the first position toward the substrate 30 to the second position, thereby triggering the switching element 40. In particular, at this time, the cushioning member 5 is deformed by being pressed by the movable member 20, so that a restoring force can be generated to the movable member 2〇, whereby the movable member 20 is returned to the first position after the external force is released. . In the embodiment, the movable member 2 〇 further has a first bent portion b 1 and a second bent portion b2 , wherein the first and second bent portions bl and b2 are adjacent to the guide groove portion 102 . In this way, the contact area of the movable member 2〇 with the guide groove portion 1Q2 can be increased to further reduce the penetration of moisture or liquid. The present invention provides a button structure, by placing a cushioning member on the substrate to support the movable member, and at the same time separating the plates by a distance, thereby effectively preventing the 妒 & & & 、 、 、 、 、 、 touch.
