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. For example, conventional push button switches have structures as shown in FIGS. 5 and 6. That is, a diaphragm 12 and a spacer 9b having a through hole 2 for holding the diaphragm 12 are placed between an insulating sheet 8b having a contact 11b on the substrate 10 and an insulating sheet 8a having a contact 11a, and insulating the leads of the diaphragm 12 and the contact 11b. A switch mechanism consisting of a spacer 9c having a small-diameter through-hole 3 therebetween, and a pressing part 4 on top of the spacer 9c.
It consists of a button 1 having a button 1 and a case 5 having an opening 6 for holding the button, and the diaphragm 12 is inverted to provide a sense of moderation.

Problems to be Solved by the Invention However, in the above configuration, an expensive two-stage spacer consisting of a spacer 9b for positioning the diaphragm 12 and a spacer 9c for insulating the leads of the diaphragm 12 and the contact 11b is used. 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 and has excellent productivity.

Means for Solving the Problem In order to solve this problem, the present invention provides a spring part that pushes up the button integrally with the case, and an actuating piece with a contact part, and also has a convex and concave moderation feel on the button. A generating part and a pressing part are provided, and when the button is pressed, the moderating feeling generating part of the button having unevenness slides against the contacting part of the case, thereby generating a feeling of moderation.

Function Compared to a configuration using a diaphragm, this configuration reduces the number of parts by making the actuating piece of the spring part and contact part integral with the case and sliding on the button's moderation sensation generating part. This reduces the material cost and man-hours, making it cheaper.Furthermore, by changing the shape of the moderating part,
Button stroke and moderation feeling can be changed arbitrarily.

Embodiment Embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows an embodiment of the drive mechanism of a push button switch according to the present invention, which has button hooks 13 extending downward at both ends of both side surfaces, a moderation feeling generating section 14 consisting of a recess at the center of the bottom surface, and Moderation feeling generating section 14
A button 16 having a pressing part 15 projecting downward in the center thereof, and a V having a cylindrical contact part 17 at the tip.
It is comprised of a case 19 that holds the button 16 and is integrally provided with an operating piece 27 made of a letter-shaped spring portion 18.

FIGS. 2a and 2b show an embodiment of a push button switch using the drive mechanism shown in FIG. The drive mechanism section is arranged on a switch mechanism section in which a spacer 24 is formed and an insulating film 26 having a contact point 25 on the lower surface is arranged on the spacer 24. The operation is such that when the button 16 is pressed in the state shown in FIG. The depression of the contact portion 17 creates a sense of moderation in the button 16. At the same time, the insulating film 26 is pressed down by the pressing portion 15 of the button 16, so that the contacts 25 and 21 come into contact and switch as shown in FIG. 2b. Button 16 excluding the pressing force of button 16
returns to the original steady state due to the restoring force of the spring portion 18.

Fig. 3 shows another embodiment of the present invention with a button hook 13.
A button 16 having a convex moderation generating part 14 and an L-shaped pressing part 15 extending downward is attached to a thin hinge 2.
Spring part 1 connected at 8 and having a contact part 17
Case 19 integrally molded with actuating piece 27 consisting of 8 pieces.
It consists of

FIG. 4 shows a push button switch using the drive mechanism shown in FIG. 3. As shown in FIG. According to
The contact part 17 moves to the lower right, and the contact part 1 moves from the convex part of the moderation generating part 14 of the button 16 to the bottom surface of the button 16.
7 is depressed, a sense of moderation is generated in the button 16. At the same time, the pressing part 15 of the button 16
, the insulating film 26 is pressed down and the contact 25
The contact point 21 comes into contact with the contact point 21 and switches as shown in FIG. 4b. When the pressing force on the button 16 is removed, the button 16 returns to its original steady state due to the restoring force of the spring portion 18. Note that the actuating piece 27 consisting of the spring portion 18 and the contact portion 17 may be integrally formed with a metal plate for a spring or the like in accordance with the pitch of the case opening.

Effects of the invention As described above, according to the invention, by integrating the actuating piece consisting of a contact part and a spring part in the case, and providing a moderation sensation generating part in the button, material costs are low and productivity is high. It is possible to supply a push button switch with a high moderation sensitivity, which is of great practical value.
