This design is used as volume switch for audio and other electronic products, which makes it easy and easy to assemble the number of up-down buttons on panel mold. The present invention relates to a push-down button switch which is provided with a recess and a guide hole having a sloping hook formed on both sides of the button inserting hole of the panel mold where the see-down button is installed. On both sides of the middle part of the see-through button, the front and rear fastening means are mounted on the rotational guide groove of the support, while the fasteners on both sides of the panel mold are pushed to both sides. As the hinge rods caught in the hooks are squeezed, the assembly and assembly work can be performed quickly and easily, and on both sides of the hinge rods The hote is formed in an unified state, but one side of the hinge rod has a protective frame ruptured, and each of the supporting ribs protruding from both sides of the panel is formed by protruding elastic ribs (Rib) horizontally inside each of the protective frames protruding from both sides. When the press-down button itself is pressed down and the press-down button itself starts the see-saw operation with the hinge rod as the starting point, the elastic rib on the opposite side is supported. When the seesaw operation is prevented and the inside of the protruding protective frame is bent and the pressing pressure is released, the self-elastic restoring force is applied to the see-through button so that the see-through button is assembled. PCB (printed circ) can be assembled by pressing assembly means and at the same time by selectively pressing one side of the see-through button When the TACT switch of the uit board is operated, the elastic rib formed integrally with the button body is responsible for the configuration that gives the home position return operation. Therefore, assembling work is much simpler than using a separate elastic return member. It is not only to improve the production efficiency of the product, but also to reduce the production cost by simplifying assembly parts.

In order to assemble the conventional see-through button switch on the panel mold in a horizontal state, a separate assembly member such as a screw (SCREW) is used, and also an elastic return member such as a spring or a cushion material is used for the seesaw operation. The assembly process is cumbersome and difficult because it requires a lot of work time due to the assembly, which has been a detrimental factor in the improvement of the productivity of the product, and also the number of cooking parts due to the use of a separate assembly member and elastic return member As a result, there was a drawback that the production cost was increased, as well as the above-mentioned factor.

Therefore, the above-mentioned conventional defects can be eliminated to make the assembling work more easily and quickly, as well as the seesaw operation of the see-through button switch after assembly is smooth, and by its own elastic restoring force after the operation. It is intended to expect smoothness and accuracy of the button operation by maintaining the always-down button is always horizontal to the panel mold, it will be described in detail according to the accompanying drawings.

That is, in the case of the see-through button-down button body 2 mounted on the button inserting hole 1 'of the panel mold 1, the push-out protrusions 3 and 3' protruding on both sides of the button molding hole 1 'on the PCB substrate 4 In the structure configured to selectively push the two tex positions (5) and (5 '), the hinge rods (6) and (6') are placed on the lower wall on the see-through button-down body (2). If it is a panel mold (1), it is a rotation guide groove (9), (9 ') and inclined surface of the support holes (7), (7') and the fasteners (8), (8 ') protruding upward and downward. (10a) and (10b) pivotally insert between the engaging ring (10), (10 '), the hinge rods (6, 6') of the see-through button body (2) Protective edges 11 and 11 'are formed on both sides, and protruding expansion protection frames 11a and 11b on one side of the hinge rod side are provided with elastic ribs 12 and 12', respectively. If the panel end is cut out, its end is always in contact with both support protrusions 13 and 13 'protruding from one side. After the seesaw tip-down button main body 1 is operated on one side by the seesaw operation, it is configured to horizontally return itself by the elastic restoring force of the elastic rib 12 or 22 'on the opposite side. b configured to surround the restraints 7 and 7 'of the hinge rods 6 and 6' as in the embodiment of FIG. ″ Shaped fasteners 8a, 8b, which are not described. 14, 14 ′ are injection molded locking fasteners 10, 10 'of fasteners 8, 8'. Mark the core hole.

Referring to the effect of the assembly and operation of the present invention configured in this way in more detail as follows.

The panel mold 1 and the PCB substrate 4 of FIG. 1 are only partially drawn to show only the site where the see-through button-down body is mounted. The button insertion hole 1 'of the panel mold 1 is shown. The hooks 10 and 10 'of the fasteners 8 and 8' protruding from the top and bottom of the back face are projected to be located above the support holes 7 and 7 'and are also caught. Since the hooks 10 and 10 'are formed with inclined surfaces 10a and 10b for guiding the insertion of the hinge rods 6 and 6' of the see-through button body 2, the assemblings thereof are formed. As shown in FIG. 5A, when the panel mold 1 is inserted, the seedling-down button main body 2 is inserted into the button insertion hole 1 'from the side, and the hinge rods 6 and 6' are moved. Since the fasteners 8 and 8 'are opened to the outside as they are pressed into the inclined surfaces 10a and 10b, the insertion and assembly of the see-through button-down body 2 is completed by one crimping operation. Fasteners (8), (8 ') ) Is returned by self-elasticity, hinge rods 6 and 10 'with which the hooks 10 and 10' are seated in the pivot guide grooves 9 and 9 'of the support holes 7 and 7'. , 6 ', so that the top-down button body (2) can be rotated by the support (7), (7') and fasteners (8), (8 ') It is fastened and assembled in a state. (See also section 5b).

The front surface of the see-through button-down button body 2 assembled as described above is slightly protruded from the button insertion hole 1 ', and also includes a protective frame 11 formed at both sides of the hinge rods 6 and 6'. ) And (11 ') are spaced apart from the back side of the panel mold (1) so that the pressing protrusions (3) and (3') are close to the tack switches (5) and (5 ') on the PCB board (4). At the same time, the elastic ribs 12 and 12 'which are soaked in the state where one end is cut off inside the extended protective frames 11a and 11b' of the protective frames 11 and 11 'are formed in the panel mold ( 1) is in contact with the supporting protrusions 13 and 13 'protruding on both sides, so that the supporting protrusions (without pressing pressure applied to the front of the see-through button-down body 2) 13) By means of elastic ribs 12 and 12 'abutted on and supported by 13', the see-through tip-down button body 2 itself is always horizontal to the panel mold 1; (See solid line in Fig. 4) Tack switch on PCB 4 If you want to increase or decrease the volume by pressing (5) or (5 ') selectively, press the side of the see-through button (2) (see the arrow direction in Figure 4). The down-down button body (2) is a seesaw operation by using the hinge rod (6), (6 ') as a pivot point, wherein the elastic rib 12 of the side receiving the pressing operation is the supporting protrusion (13) At the same time, the pressing protrusion 3 presses the tack switch 5 on one side and the pressing protrusion 3 'on the other side, the protective frame 11' and the expansion protection frame 11b. In contrast to the upward operation, the elastic rib 12 'inside the extension protection frame 11b is elastically bent in the state in which the upward movement is blocked by the support protrusion 13', and then the elastic rib 12 'is operated (see the virtual line portion in FIG. 4). When the release pressure applied to one side of the Si-down button-down body (2) is released, it flexes flexibly. The elastic ribs on one side of the see-through button-down button body 2 returning the see-through button-down body 2 itself to its original state by the action of the elastic force of the elastic rib 12 ' 12) is abutting on the support protrusion (13) to prevent rocking phenomenon, the shisui up-down button body (2) can maintain a stable horizontal state instantaneously and accurately after the selected up-down or down operation, such as volume It is possible to induce higher and lower operations more reliably.

On the other hand, in the above, the fasteners 8 protruding the hinge rods 6, 6 'of the see-through button-down button main body 2, 6' on the button insertion hole 1 'of the panel mold 1, ), (8 ') has been described an embodiment of the configuration for assembling and fastening the engaging ring (10), (10') for the operation of opening and closing the retracted to the original position, but the same practice in Figure 6a, b For example, the fasteners 8a and 8b surround the support holes 7 and 7 'so that an insertion space for the hinge rods 6 and 6' can be formed. Even if it is configured as ″, the hinge rods (6) and (6 ') rotate the guide grooves (9) and (7') of the guide holes (9) and (9 ') during the seesaw operation of the see-through button-down body (2). ') And ″ It is possible to smoothly induce the seesaw operation without any deviation between the " type fasteners 8a and 8b ", and in this embodiment, the elastic action of the elastic ribs 12 and 12 ' Working together, you can expect a smooth working effect.
