2. Description of the Related Art A conventional technique will be described with reference to panel switches shown in FIGS.

According to FIG. 3, a switch 4a is formed by attaching a diaphragm 2 on an insulating substrate 1 with a tape 3.
Is formed, and a plurality of switches 4a are arranged.
And a connecting button 8 having a plurality of buttons 6 and a connecting portion 7 integrally formed by a hinge portion 5, sandwiched by a case 10 having a button opening 9, and the switch unit 4 being screwed by a screw 11. Case 10
Was fixed to form a panel switch.

FIG. 4A is a detailed view of the structure of the panel switch shown in FIG. 3, in which a horseshoe-shaped contact 12 formed of a conductor on an insulating substrate 1 and a circular contact 13 formed adjacent to the inside thereof. An approximately dish-shaped diaphragm 2 made of a metal having a spring property such as stainless steel or phosphor bronze for a spring is formed thereon by using a tape 3 in which an adhesive is applied to polyester having a thickness of 12 to 100 microns on one surface. Attached so as to be in contact with the horseshoe-shaped contact 12 and concentric with it,
A rod 14 that moves up and down the center of the diaphragm 2 by operating the button 6 is arranged.

Next, the operation will be described with reference to FIG.
When the button 6 is depressed in the state described above, the rod 14 pushes down the diaphragm 2, and the diaphragm 2 is inverted as shown in FIG. 4 (b), and the diaphragm 2 and the circular contact 13 come into contact with each other. The contact 13 is electrically conducted, and the switch is switched.
When the pressing force of the button 6 is removed, the diaphragm 2 returns to the state shown in FIG .

FIG. 5A shows another example of a conventional panel switch, in which a contact 15a on an upper surface of an insulating substrate 15 and a contact 16a on a lower surface of an insulating sheet 16 having elasticity are connected to an insulating sheet 17.
The switch unit 6 is configured so as to face with a gap through the opening of the switch unit 6, and a button 18 having a rod 17 is disposed thereon via a diaphragm 20 disposed corresponding to the contact 15 a, and a case 19 is provided. The button 18 is held. FIG. 5A shows a steady state, and FIG. 5B shows a state in which the button 18 is pressed to invert the diaphragm 20 and the contacts 15a and 16a are brought into contact to perform switching.

[0007]

However, in the above configuration, the sound generated when the diaphragm is inverted by the rod of the button is recorded in a small microphone in the vicinity of a small cassette recorder or a video movie. was there.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a panel switch which solves the above-mentioned problem and reduces the sound generated when the diaphragm is inverted.

[0009]

According to the present invention, in order to solve the above-mentioned problems , a diaphragm is taped on an insulating substrate.
Form an individual switch and combine this switch
A switch unit that covers the top of several switch units
This is a panel switch composed of a sheet provided with an adhesive on the knit side .

[0010]

According to the above construction, the sound of the diaphragm inversion and the impact sound of the diaphragm when it is inverted are covered with a sheet provided with an adhesive to reduce the spread of the sound, and the moderation of the diaphragm is further reduced by the sheet provided with the adhesive. This is to reduce the reversal sound of the diaphragm and the impact sound when the diaphragm is reversed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the panel switch of the present invention will be described below with reference to FIGS.

First, FIG. 1 is an exploded perspective view of a panel switch. By attaching a diaphragm 22 on a printed circuit board 21 with a tape 23, an individual switch 24a is formed.
And by arranging a plurality of switches 24a.
A switch unit 24, on which a sheet 25 made of a polymer material such as vinyl chloride or polyester having a lower surface adhesive 25a is disposed, and a plurality of buttons 27 are connected to a plurality of A connection button 29 integrally formed with the button unit 28 is sandwiched by a case 31 having a button opening 30, and the switch unit 24 and the case 31 are fixed by screws 32 to form a panel switch.

FIG. 2A is a detailed view of the switch structure shown in FIG. 1, and shows a horseshoe-shaped contact 3 formed of a conductor on an insulating substrate 21.
6 and a circular contact 33 formed adjacent to the inside thereof
And a tape 23 in which a substantially dish-shaped diaphragm 22 made of a metal having a spring property such as stainless steel or phosphor bronze for a spring is coated on one side with an adhesive on polyester having a thickness of 12 to 100 microns. Is attached so as to be concentric with and in contact with the horseshoe-shaped contact 36, a sheet 25 having a lower surface adhesive 25a is disposed thereon, and the center and the lower surface of the diaphragm 22 are further disposed thereon. Adhesive 25a
Buttons 2 so as to face each other via a sheet 25 having
A rod 35 that moves up and down by the operation of 7 is arranged.

Next, the operation of the above embodiment will be described. When the button 27 in the state of FIG. 2A is depressed, the rod 35 is moved to the sheet 25 having the lower surface adhesive 25a.
The diaphragm 22 is depressed through the diaphragm 22, and the diaphragm 22 is inverted as shown in FIG.
The circular contact 33 comes into contact with the horseshoe-shaped contact 36.
And the circular contact 33 are electrically connected to the switch unit 2
4 are performed. At this time, the sound generated by the diaphragm is reduced by the elastic force of the sheet 25, and at the same time, the lower surface adhesive 25a of the sheet 25 covers the diaphragm 22, thereby preventing the sound generated by the diaphragm 22 from spreading. Next, when the pressing force of the button 27 is removed, the state returns to the state shown in FIG .

[0015]

As described above, by sandwiching the sheet with the adhesive between the button rod and the switch, the sound generated when the diaphragm is inverted is reduced, and the sound generated when the panel switch is switched is reduced.
