(20) has a length and width of approximately 5m+a and a height of approximately 2m1
The switch case (20) has a circularly opened recess (21) formed on the upper surface thereof, and a central contact (22) is formed on the bottom plate surface of this recess (21). and outer contact (23) (23)
The terminals (24) and (25) integrated with these contacts (22) and (23) are molded simultaneously with the switch case (20) so that they protrude outward from the switch case (20), and the recesses are also formed. An engaging stepped portion (27) of the metal cover (26) to be attached is formed near the inner upper end of (21), and a circular tightening step is formed around the entire circumference of this engaging stepped portion (27). A bulge (28) is formed to protrude upward. As shown in FIG. 6(a), this bulging part (28) has an inner side that stands up almost vertically, an outer side that is oblique, and an upper part that is thinner, and has a head (33) and a lower outer part (34). is rounded.

A downward dish-shaped conductive shorting plate (29) is provided, and
A disk-shaped metal cover (26) integrally formed with the key stem (30) is engaged on the engagement step (27). If necessary, a groove (35) is formed on this engagement step (27) as shown in FIG. 6, and a backing (36) is fitted therein.

As shown in (c), the metal cover (26) is fixed by bending the bulge (28) inward using the spin crimping fitting (31). That is, the spin crimping fitting (31) has a cylindrical body whose outer diameter is slightly larger than the bulging portion (28), and has a tapered surface (32) formed on the lower end surface so that the height becomes higher in the direction of the center. That's what happens.

、膨出部（２８）にひび割れが生じにくい。Such a spin crimping fitting (31) is shown in Fig. 6(a).
As shown in FIG. 2, it rotates at high speed while coming into contact with the bulge (28) and applying pressure from above. Then, as shown in FIG. 6(b), since the head (33) of the bulge (28) has a rounded shape, the head (33) gradually bends. When further pressurized and rotated at high speed, the head (33) comes into contact with the upper surface of the metal cover (26) as shown in FIG. 6(c), and when further pressurized and rotated at high speed, the bulge (28) The middle portion of the metal cover (26) also comes into close contact with the upper surface of the metal cover (26). At this time, since the base (34) on the outer side of the lower end of the bulge (28) has a rounded shape, cracks are less likely to occur in the bulge (28).

。Note that since the metal cover (26) shown in FIG. 1 has a flat plate shape, there is a risk that slight sliding may occur at the crimped portion when the key stem (30) is moved up and down. In order to improve this, the metal cover (26) is shaped like a disc spring as shown in Figure 4, and furthermore, it is shaped like a diaphragm as shown in Figure 5 to eliminate lateral sliding. Can be done.

ある。Further, the bulging portion (28) is not limited to being fixed by folding inward, but may be fixed by folding outward as shown in FIG. 8. In this case, the spin crimping fitting (31
Of course, the tapered surface (32) of ) becomes higher toward the outer periphery.
