Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a push button switch used in an operation panel of an electronic device.

BACKGROUND TECHNOLOGY In recent years, electronic devices have become increasingly computerized, and push button switches used in the operation panels of electronic devices have a good sense of moderation, a stroke suitable for electronic devices, and are inexpensive. something is desired. A conventional push button switch of this type has a structure as shown in FIGS. 3 and 4, for example. That is, on the substrate 10, a diaphragm 12 and a spacer 9b having a through hole 2 for holding the diaphragm 12 are placed between the insulating sheet 8b having the contact 11b and the insulating sheet 8a having the contact 11a, and the diaphragm 12 and the contact 11.
From the case 4, which includes a switch mechanism sandwiching a spacer 9c having a small diameter through hole 3 for insulating the lead 7 of b, a button 1 having a pressing portion 6 thereon, and an opening 5 for holding the switch mechanism. The inversion of the diaphragm 12 provides a sense of moderation.

Problems to be Solved by the Invention However, the above configuration uses an expensive two-stage spacer consisting of a spacer 9b for positioning the diaphragm 12 and a spacer 9c for insulating the diaphragm 12 and the lead 7 of the contact 11b. Furthermore, since the diaphragms 12 had to be placed one by one on top of the diaphragms, material costs were high and productivity was poor. Furthermore, in order to lengthen the stroke, the diameter of the diaphragm 12 must be increased, and in applications where the button pitch is narrow, the stroke is inevitably limited.

The present invention is intended to solve the above-mentioned problems, and aims to provide a push button switch that is inexpensive, has excellent productivity, and has a good sense of moderation.

Means for Solving the Problem In order to solve this problem, the present invention provides an actuating body that has a spring part, a contact part, and a pressing part that pushes up the button integrally in the case, and also provides a button with a moderation function. The button is provided with a feeling-generating portion, and when the button is pressed, the feeling-of-moderation-generating portion of the button, which has unevenness, slides against the contact portion of the case, thereby generating a feeling of moderation.

Effect Compared to a configuration that uses a diaphragm, this configuration allows the actuating body, which has a spring part, a contact part, and a pressing part, to be integrated with the case, and has a structure in which it slides on the button's moderation sensation generating part, reducing the number of parts. decreases,
Since material costs and man-hours can be reduced, it is cheaper,
Furthermore, by changing the shape of the moderation feeling generating section, the button stroke and moderation feeling can be arbitrarily changed, and the pressing section having spring properties makes it possible to stabilize the contact when the button is pressed.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Fig. 1 shows an embodiment of the drive mechanism of the push button switch of the present invention, which has button hooks 13 extending downward at both ends of both sides, and a recess 14 with one side sloped on the bottom, and a recess 14 connected to the recess 14. a button 17 having a moderation generating part 16 made of a convex part 15 having a vertical surface, a spring part 18 formed in a V-shape continuous to the case 22, and a button 17 provided continuously to the spring part 18. Contact portion 1 that comes into contact with the moderation generating portion 16
9 and a pressing portion 20 whose end extending downwardly from the contact portion 19 is a free end, and is integrally molded with the case 22 and protrudes into the button opening of the case into which the button 17 is inserted. The entire provided body is composed of a substantially inverted V-shaped actuating body 21.

FIG. 2 shows an embodiment of a push button switch using the drive mechanism shown in FIG.
a spacer 27 on which a through hole 26 is formed at the contact portion;
The driving mechanism section is arranged on a switch mechanism section in which an insulating film 29 having a contact point 28 on the lower surface is arranged on the spacer 27, and its operation is performed by pressing the button 17 in the state shown in FIG. 2a. As a result, the spring portion 18 having the pressing portion 20 of the actuating body 21 moves to the lower right, and the moderation generating portion 1 of the button 17 is moved to the lower right.
The contact portion 19 of the spring portion 18 falls into the recess 14 of the button 17, thereby creating a sense of moderation in the button 17. At the same time, the pressing part 20 presses down the contact 28 through the insulating film 29, and switching of the contact 28 and the contact 24 is performed (see FIG. 2b). That is,
By pressing the button 17, the operating body 21 is driven to switch the contacts 28 and 24 of the switch mechanism. When the pressing force on the button 17 is removed, the button 17 returns to its original steady state due to the restoring force of the spring portion 18 (see FIG. 2a).

Effects of the Invention As described above, according to the present invention, a substantially inverted V-shaped actuating body is provided integrally with the case, and this actuating body is connected to the spring portion provided by connecting it to the case, and the spring portion is connected to the spring portion. A contact part that slides on the moderation generating part provided as a button, and a free end extending downward from the contact part to transmit the pressing force from the button to the switch mechanism part through the contact part. Since it is constructed with a pressure transmitting part, it is possible to provide a push button switch with low material cost and good productivity, and it can also be made with an excellent sense of moderation, which is of great practical value. It is.
