Known closed miniature switches use many different methods to ensure their tightness. The switch shown in Fig. 1 is a representative example. The switch body is divided into two parts, with a pad therebetween. Fig. 2 is a sleeve placed on the base and sealed with an adhesive. In addition, the one shown in FIG. 3 is an example in which a molten plug is set in advance in the state of FIG. 2 in order to prevent the air enclosed in the switch from forming bubbles in the self-adhesive part during the hardening process; FIG. 4 is to be opened on the switch body The hole is sealed with a seal. Also, in the conventional example, there is an example in which the base and the sleeve are fusion-bonded by using ultrasonic vibration as proposed in Japanese Patent Publication No. 3-45496. The conventional closed miniature switch is divided into two parts, the upper part and the lower part, which are provided with a pad therebetween. There are problems with the fitting strength of the upper and lower divided parts and the cost increase caused by adding the pad. Difficult to connect,-the problem of assembling the connecting parts into the deep part of the box-shaped base. In addition, if the sleeve is sealed with an adhesive after being sleeved on the base, although there is no problem of the aforementioned strength or assembly shape, the air enclosed inside the switch will expand due to changes in ambient temperature during the process of curing the adhesive. Therefore, the airtightness may be reduced due to air bubbles in the adhesive part. For the 4 I.

Explanatory drawing of part (6) of the invention. The hermetically sealed small switch constructed in the foregoing manner is formed in a manner that the base 10 and the sleeve 7 are floatingly fitted with a gap as described above, and the outer contour of the sleeve 7 is formed only slightly smaller than its size. The base, therefore, can receive the vibration energy of the vibrator (resonator) with respect to the sleeve 7 held in the fixed jig, and the base 10 can vibrate without loss of ultrasonic energy, so it can be welded with very good efficiency. In other words, since welding can be performed efficiently with the least amount of energy, it has the effect of almost completely eliminating the influence of the ultrasonic energy on the inside of the switch. In addition, 'the melted burr formed by the fusion space 8 overflowing from the joint surface to the outside is formed along the inner surface of the fixed jig, and at the same time, the melted burr is pressed flatly by the inner surface of the fixed jig by the vibration energy during melting. Therefore, the appearance of the switch can be formed very beautifully, and has the excellent effect of eliminating the need for melting burrs and trimming operations in the past. "Figures I3 and 14 show the appearance of the sealed miniature switch of the present invention after the welding step. In the figure, although the fused burr is emphasized, 'the fused burr formed by the present invention is practically hardly noticeable, and the installation of the reinforcing plate of ffl 13 or the continuous installation shown in FIG. 14 will not cause an obstacle. Fig. 11 is a partially enlarged view showing an ultrasonic welding step of another embodiment of the sealed miniature switch of the present invention. Compared with the previous embodiment, a stepped portion is provided around the joint portion to reduce the amount of sag of the molten burr.
