Specifically, the edge portion 52 of the elastic member 50 is disposed on the spacer 60 such that the elastic deformation portion 54 of the elastic member 50 faces the first contact 74 with the opening 64 interposed therebetween (refer to 3)). At this time, one of the elastic members 50 (the elastic member 50 on the right side of Fig. 7) is surrounded by the four φ convex portions 86 of the holding member 80. The other elastic member 50 (the elastic member 50 on the left side of Fig. 7) is surrounded by the two convex portions 86 and the tapered portion 88 of the holding member 8''''''' Thereby, it can be restricted that the elastic member 50 moves in a direction parallel to the main surface 72 of the substrate 70 with respect to the spacer 60 and the substrate 70. That is to say, the convex portion 86 and the tapered portion 88 of the holding member 80 function as a restriction means. Next, as shown in Fig. 8, the two rod portions 40 are respectively disposed on the elastic member 50. At this time, one of the rod portions 40 (the rod portion 40 on the right side of FIG. 8) is surrounded by the four convex portions 86 of the holding member 80. The other rod portion 40 (the rod portion 40 on the left side of Fig. 8) is surrounded by the two convex portions 86 and the tapered portion 88 of the holding member 80. Thereby, it is possible to restrict the movement of the rod portion 40 in the direction parallel to the main surface 72 of the substrate 70 with respect to the spacer 60 and the substrate 70. That is, the convex portion 86 and the tapered portion 88 of the holding member 80 function as a restricting means. After the spacer 60, the elastic member 50, and the rod portion 40 are sequentially disposed on the substrate 70 in this manner, the spacer 30 is fitted to the arrangement portion 82 of the holding member 80. Then, the outer casing 20 is placed on the holding member 80, and the outer -9-M441616 casing 20 is pushed toward the holding member 80 side. The hook portion 85 of the holding member 80 is brought into the hook hole 24a of the hook portion 24 with the hook portion 85' of the holding member 80 being elastically deformed. Thereby, the outer casing 20 is fixed to the holding member 80. In a state where the outer casing 20 is fixed to the holding member 80, the elastic portion 54 is gently pressed by the pressing portion 46, and the rod portion 40 is brought into contact with the elastic member 5''. Thereby, the operation of the elastic member 50 in the direction orthogonal to the main surface 72 of the substrate 70 is restricted. In the state in which the outer casing 20 is fixed to the holding member 80, the two annular projections 38 of the spacer 30 are fitted to the opening portions 22 of the outer casing 20, respectively. After the outer casing 20 is fixed to the holding member 80, the two buttons 10 are respectively disposed in the arrangement portion 34 of the spacer 30. Of course, the outer casing 20 may be fixed to the retaining member 80 after the button 10 is placed in the arranging portion 34. As shown in Fig. 9, in the switch 1, by pressing the button 10, the elastic member 50 is pressed against the spacer 30 and the rod portion 40, and the elastic deformation portion 54 of the elastic member 50 is elastically deformed. Then, the elastic deformation portion 54 is in contact with the first contact 74 through the opening portion 64 of the spacer 6A. Thereby, the first contact 74 and the second contact 76 are energized via the elastic member 50 and the spacer 60, and the predetermined circuit signal is output via the cable 90. The output circuit signal, for example, is transmitted to a control unit such as an electric shifting machine. The edge portion 5 2 ' of the elastic member 5 may be in contact with the convex portion 86 or the tapered portion 88 of the holding member 80 in a state where the button 10 is not pressed. On the other hand, as shown in Fig. 9, in the state where the stroke of the button 1 is maximized, the arrangement portion 34 of the edge portion 14 that is in contact with the spacer 3 is configured to prevent the button 1 from moving beyond the predetermined position. Itinerary. -10- M441616 By this switch 1, the stroke of the elastic member 50 can be increased by the thickness portion of the spacer 60. This allows the user to get a full sense of operation. Further, by making the spacer 60 detachable, the spacer 60 of various thicknesses can be detachably attached, and the degree of deformation of the elastic deformation portion 54 can be obtained to obtain a user's feeling of operation. In order to restrict the movement of the elastic member 50 in the direction orthogonal to the main-surface 72, it is preferable to change the length of the shaft portion 44 of the rod portion 40 or to change φ by the presence or absence of the spacer 60 or the thickness of the spacer 60. The thickness of the arrangement portion 34 of the gasket 30. <Modifications> The specific structure of the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the scope of the novel contents. In the following description, members which are not described are the same members as those of the above embodiment. In the above-described embodiment, the elastic member 50 is described as being viewed in a disk shape in a plan view direction, and the shape of the elastic member Φ is not limited thereto. For example, the shape of the elastic member can be selected by observing a triangular shape in a plan view direction, a quadrangular shape in a plan view direction, a polygonal shape in a plan view direction, and an elliptical shape in a plan view direction. On the other hand, the elastic member 50' may have a concavo-convex portion for restricting the movement on the surface of the spacer 6'' at the edge portion 52. In this case, the spacer 60 may have a concavo-convex portion for engaging with the uneven portion of the edge portion 52 of the elastic member 50 on the surface. The shape of the opening portion of the barrier is preferably a shape corresponding to the shape of the elastic member. Therefore, the shape of the elastic member is a triangle in a plan view, and a quadrangle in a plan view, and an ellipse in a plan view. - M441616. The shape of the opening of the spacer is triangular, square, or elliptical. . Further, in the above-described embodiment, the description will be made on the case where one elastic member 50 is used, and a plurality of elastic members 50 may be stacked. That is, it further includes at least one additional elastic member which is elastically deformed by pressing the button 10 on the opposite side of the first contact 74 of the substrate 70 and stacked on the elastic member 50. In the above-described embodiment, the position of the spacer 60, the elastic member 50, and the rod portion 40 is limited, and an example of the restricting member, that is, the convex portion 86 and the tapered portion 88, is provided in the holding member 80. Further, the constituent elements provided with the restriction means are not limited to the holding member. For example, the restriction means may be provided to the spacer 30 and the outer casing 20. The shape and position of the first contact and the second contact are not limited to the above embodiments. As long as it conforms to the case where the spacer is only connected to the second contact and the elastic deformation portion of the elastic member is in contact with the first contact in the state of pressing the button; the shape and position of the first contact and the second contact Can be set freely. In the above embodiment, the bicycle switch for the two button types of the button 'rod portion, the elastic member, the first contact point, and the second contact point is used, and the new type is not limited to this. . The new ' can also be applied to a button type bicycle switch, or to a three-button or more bicycle switch.
