Reference numeral 13 denotes a terminal, and the terminal 13 is formed on the holding plate 14. A switch structure is configured by a switching operation between the contact plate 12 and the terminal 13 in accordance with the vertical movement of the button shaft 2.
FIG. 2 is a top view showing the shape of the hole 4 formed in the case 3 and through which the button shaft 2 passes. In FIG. 2, reference numeral 21 denotes a concave portion formed on the circumferential side surface of the hole 4, and the radius of curvature of the curved portion of the concave portion 21 is set to be substantially equal to the radius of the button shaft 2. The recesses 21 are provided at substantially equal angles at a total of eight locations along the circumferential direction of the hole 4 in up, down, left, right, and oblique directions at 45 degrees. Reference numeral 22 denotes a convex portion, and the convex portion 22 is provided continuously to the adjacent concave portion 21. Next, the operation of the above embodiment will be described. When the operation button 1 is operated in the circumferential direction with respect to the axis, up, down, left, right, and oblique (45 degrees), the slider 5 moves via the button axis 2. The contact 8 slides in contact with the upper surface of the substrate 7 according to the sliding operation of the slider 5. FIG. 3 shows an arrangement relationship between the contact 8 and the conductor 9 provided on the upper surface of the substrate 7. The contacts 8 are provided at four places on the lower surface of the slider 5,
a to 8d always move in the same direction. Also,
The contacts 8a and 8d and the contacts 8b and 8c are respectively connected by conductors (not shown). Here, for example, when the operation button 1 is operated in the upper right diagonal direction of 45 degrees, the contacts 8a to 8d also move in the upper right diagonal direction of 45 degrees.
d contacts the conductor 9j. Since the contacts 8a and 8d are connected by a conductor, a connection is made between the conductors 9a and 9j. At this time, the contact 8c is located between the conductors 9c and 9d. Thereby, an electric signal corresponding to the operation direction of the operation button 1 can be extracted through the conductors 9a and 9j. At this time, as shown in FIG. 2, the button shaft 2 is in a state of being fixed in a concave portion 21 formed on a circumferential side surface of the hole 4 of the case 3.
