Causes the electronic device to be placed incorrectly. SUMMARY OF THE INVENTION [0005] In view of the above circumstances, it is necessary to provide a button that can prevent false touches. [0006] A button is disposed between a casing and a substrate of the electronic device, and the casing is provided with a receiving hole. The button comprises a pressing member received in the receiving hole, and a switch 7L fixed on the substrate. The elastic member is held between the pressing member and the substrate, and the elastic member is elastically deformed when pressed by the pressing member, so that the pressing member touches the switching element. 099119758 Form No. A0101 Page 3 of 13 0卯2034955-0 201201234 [0007] The elastic member of the above-mentioned button can be pressed against the pressing member so that the pressing member does not cause slight pressure or self-gravity due to the housing. Intersists with the switching element to prevent the button from being accidentally touched. [0010] [0012] Embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Referring to Figure 1, a button 1 of a preferred embodiment of the present invention is disposed between a housing 101 of an electronic device (not shown) and a substrate 105. Referring to FIG. 2, the housing 101 has a receiving hole 102. In the present embodiment, the receiving hole 102 is a stepped hole, and the large aperture end is located on the inner side of the housing 1〇1. The large-diameter end of the accommodating hole 102 is formed with a truncated hole portion 104 (refer to Fig. 3). Two fixing members 1 〇 3 are provided on one surface of the housing 101. The fixing member 103 may be a screw, a riveting stud, a heat stake, or the like. In the present embodiment, the fixing member 103 is a heat-melting column. In the present embodiment, the substrate 105 is an electric raft. The substrate 105 is provided with a ..:.... 二. Two locking holes 106. The fixing member 1〇3 of the casing 101 is fixed by the locking hole 106. The button 100 includes a pressing member 20, a switching member 30, and an elastic member 40. The pressing member 20 is received in the receiving hole 102 of the housing 101. The switching element 30 is fixed to the substrate 105 and electrically connected to the substrate 105. The elastic member 40 is abutted between the substrate 105 and the pressing member 20. Referring to Fig. 3 together, the pressing member 20 includes a pressing portion 21, a guiding portion 23, and a contact portion 25. The pressing portion 21 and the contact portion 25 are respectively fixed to both ends of the guiding portion 23. The guide portion 23 may have a shape of a cylinder, a truncated cone, a square, or the like. 0199119758 Form No. A0101 Page 4 of 13 0992034955-0 [0013] 201201234 向 [0014] The directional portion 23 is received in the hole portion 104 of the accommodating hole 102 of the casing 101. The guide portion 23 has a guide surface 231 which extends in a direction oblique to the direction of the wheel of the guide portion 23 and which is inclined toward one end of the guide portion 23 and the contact portion 25. In the present embodiment, the guide portion 23 has a truncated cone shape, and the guide surface 231 is a circular arc-shaped side surface of the guide portion 23. When the pressing member 2 slides in the receiving hole M2 of the housing ιοί, the guiding surface 231 of the guiding portion 23 cooperates with the side wall of the hole portion 1〇4 of the receiving hole 102 of the housing ι1, so that the pressing member 20 slides along the axial direction of the guide portion 23. It can be understood that the pressing portion 21 and the guiding portion 23 can be a one-piece molding structure. The end face of the switch member 30 has an interesting control_31. The pressing member 2 is pressed to the touch portion 31 so that the switching member 30 is touched. [0015] The elastic member 40 can be spring, foam, elastic, rubber or the like: In the present embodiment, the elastic member 40 is a foam having a through hole 41. When assembled, the switching element 30 is housed in the through hole 41, and the elastic member 40 is abutted between the substrate 1〇5 and the guide portion 23 of the pressing member 20. [0016] Referring to FIG. 1 to FIG. 3 at the same time, when the button ί00 is assembled, first, the switching element 30 is fixed on the substrate 1. Then, the elastic member 40 is sleeved on the switching element 30. Next, the pressing member 20 is received in the accommodating hole 102 of the casing 101. Finally, the fixing member 103 of the housing 101 is passed through the locking hole of the substrate 1〇5, and the housing 1〇1 is fixedly connected with the substrate 1〇5, so that the elastic member 4〇 abuts against the pressing member 2 The guide (4) is between the substrate 1 and 5. When the button 100 is touched, a pressure is applied to the (four) member 2 to slide the pressing member 2 into the receiving hole 102 of the casing 101 toward the switching member 30. The pressing member 20 presses the elastic member 40 to elastically deform the elastic member 4 until the one end of the pressing portion 21 of the pressing member 099119758 Form No. A0101 5/13 pages 0992034955-0 201201234 and the touch portion of the switching element 30 31 is in conflict, thereby causing the switching element 30 to be touched. [0018] The elastic member 40 of the button 100 abuts against the pressing member 20, so that the pressing member 20 does not come into contact with the switching member 30 due to slight pressing of the housing 101 or its own gravity, thereby preventing the button 100 from being accidentally touched. Further, the pressing member 20 of the button 100 has a guiding portion 23, so that the pressing member 20 is not jammed due to the misalignment. Therefore, the guiding portion 23 can prevent the button 100 from being misaligned when touched. [0020] Further, the guiding portion 23 of the pressing member 20 has a guiding surface 231 inclined with respect to the moving direction of the pressing member 20. The receiving hole 102 of the housing 101 has a hole portion 104 matching the guiding surface 231. The pressing member 20 is brought into close contact with the side wall of the accommodating hole 102 to prevent dust from falling into the button 100. Moreover, since the guiding surface 231 is inclined with respect to the moving direction of the pressing member 20, the sliding resistance of the pressing member 20 is reduced, and the touch of the button 100 is more flexible. [0021] Further, the guiding portion 23 of the pressing member 20 is in the shape of a truncated cone, and the hole portion 104 of the receiving hole 102 of the housing 101 is also in the shape of a truncated cone, so that the pressing member 20 slides in the receiving hole 102 of the housing 101. The center of the accommodating hole 102 slides to keep the gap between the pressing member 20 and the accommodating hole 102 uniform, so that the positioning of the pressing member 20 is more accurate, and the touch precision of the button 100 is further improved. [0022] It can be understood that the guiding surface 231 of the guiding portion 23 of the pressing member 20 can also be parallel to the moving direction of the pressing member 20. At this time, the receiving hole 102 of the housing 101 has a tilting direction with respect to the moving direction of the pressing member 20. The side wall has the same function as when the button 100 has a direction in which the guide surface 231 of the guide portion 23 of the pressing member 20 is inclined with respect to the moving direction of the pressing member 20. 099119758 Form No. A0101 Page 6 of 13 0992034955-0 201201234 [0023] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
