た。However, in the case of a switch device in which the hook portion of such an elastic swelling member is pushed into the hole of the substrate to be locked, the elastic swelling member is made of rubber or the like. The hook is easily deformed because it is formed of the elastic material, and to protrude to a position where the hook is securely locked to the lower surface of the substrate, the board is turned upside down and the hook is pulled to lock the hook. This work was troublesome because it was necessary to ensure that the fitting was performed until the fitting was completed.

膨出部材１１を基板１２上に接着する。The elastic swelling member 11 is fixed to the substrate 12 by fitting several projections 22 provided on the lower surface thereof into the positioning holes 23 of the substrate 12 and positioning them. Pressed portion 1 of elastic swelling member 11
An adhesive having a high adhesive force is applied to a portion 12a immediately outside the sheet 6 and a sheet-like pressing member 17 is covered from above the elastic swelling member 11 so that the swelling portions 14 enter the respective openings 18 respectively. 2 so that the pressed portion 16 of the elastic swelling member 11 is pressed .
In the same figure, the phase is different by 180 ° in the circumferential direction of the pressed portion 16.
Then, the upper and lower portions are bonded to the substrate 12, and the elastic swelling member 11 is bonded to the substrate 12.

が増す。As described above, the switch device 10 is easy to assemble because the pressed portion 16 of the elastic swelling member 11 is pressed by the pressing member 17 and fixed by bonding, and the lower surface of the elastic swelling member is bonded. When the switch device 10 is directly fixed to the substrate, the lower surface thereof needs to have an area large enough to obtain a sufficient adhesive strength, so that the shape of the elastic swelling member is limited accordingly. Since there is no need to do so, the degree of freedom in designing the shape increases.

によって接着剤層の厚みが微妙に異なる。In the conventional method of applying and bonding an adhesive to the lower surface of the elastic swelling member, an adhesive layer is formed between the lower surface of the elastic swelling member and the upper surface of the base member. The thickness of the adhesive layer slightly varies depending on the amount and / or the pressing force at the time of bonding to the bonding surface.

ッチレスポンス上のバラツキが表われる。Because the distance between the movable contact and the fixed contact varies depending on the thickness depending on this case, the one-make contact type may have little effect. However, the multiple-make contact type is used for the touch response switch. In this case, the slight difference in the thickness greatly affects the touch response, and a variation in the touch response of the keys arranged side by side in one musical instrument or a variation in the touch response between the musical instruments appears.

If the touch response switch is constituted by a second pair of the second movable contact 132 and the second fixed contact 52 that will be contacted later, the above-mentioned variation in the touch response between the keys and between the instruments due to the adhesive layer occurs. do not do. Therefore, there is an effect that an inexpensive and accurate touch response switch can be realized.

In this switch device, the pressing member 47 formed of a sheet-like polyester film, for example, is made larger than the pressing member 17 of the embodiment of FIG. 1 and is separated from the elastic swelling member 11 of the pressing member 47 by a predetermined distance. The narrowed position is narrowed down to a certain depth in a direction away from the substrate 12 to form a narrowed portion 46 (a narrowed portion is also integrally formed with a mold). A lower contact 49 is formed corresponding to the upper contact 48 to constitute the membrane switch 40.

Usually, they are located at separate positions as shown in the figure, and they come into contact with each other when the diaphragm portion 46 is pressed down. The contacts close. With this configuration, the membrane switch 40 can be formed in the switch device at the same time, so that the overall cost of the entire device such as an electronic musical instrument can be further reduced, and the switches can be downsized.

きる。As described above, according to the present invention, the pressed portion of the elastic swelling member mounted on the base member such as the substrate is pressed by the sheet-shaped pressing member and adhered to the base member. Since the elastic swelling member can be securely fixed to the base member by a simple operation, the cost can be reduced by improving the assembling workability, and the lower surface of the elastic swelling member is directly bonded to the substrate. Because we do n’t do
Since there is no need to restrict the shape of the lower surface of the elastic swelling member, the degree of freedom of the shape surface increases. Further, since the elastic swelling member can be fixed to the soft and thin base member having a small thickness, the range of use can be further expanded.
