A seesaw button device according to an embodiment of the present invention will be described below.
1 is a cross-sectional view of a main part of a seesaw button device according to the present embodiment, FIG. 2 is a plan view of a main part showing a switch operation unit of the seesaw button device, and FIG. 3 is a perspective view from the surface showing the seesaw button of the seesaw button device. 4 is a perspective view from the back side showing the seesaw button, FIG. 5 is an exploded perspective view of the main part of the seesaw button device, and FIG. 6 is a perspective view of the main part showing the back side of the switch operation unit of the seesaw button device. is there.

As shown in FIG. 1, the seesaw button device according to this embodiment includes a substrate 10 having a plurality of switches 11, an escutcheon 20 that covers the substrate 10, a switch operation unit 30 formed on the escutcheon 20, and a switch operation unit 30. The seesaw button 40 is provided.
As shown in FIG. 2, the switch operation unit 30 includes a seesaw main body 31 that receives the seesaw button 40 on one surface, and a variable unit 32 that connects the seesaw main body 31 to the escutcheon 20.
An outer peripheral space 33 is formed on the outer periphery of the seesaw main body 31, and an inner peripheral space 34 is formed on the seesaw main body 31. The seesaw main body 31 is formed with two openings 35 and 36 for positioning. One opening 35 is larger than the other opening 36.
Further, as shown in FIG. 1, a push rib 37 that presses the switch 11 is formed on the other surface of the seesaw body 30.
The switch operation unit 30 is integrally formed with the escutcheon 20.

As shown in FIGS. 3 and 4, the seesaw button 40 is formed on the pressing portion 41 whose surface is pressed, the outer peripheral rib 42 formed around the back surface of the pressing portion 41, and the back surface of the pressing portion 41. It has a fitting claw 43, a positioning pin 44 formed on the back surface of the pressing portion 41, and a recess 45 formed in a part of the outer peripheral rib 42.
The dimension between the two positioning pins 44 is larger than the dimension between the pair of fitting claws 43. Further, the two positioning pins 44 and the pair of fitting claws 43 are arranged so that a virtual line connecting the two positioning pins 44 intersects a virtual line connecting the pair of fitting claws 43.

Next, the attachment of the seesaw button 40 to the switch operation unit 30 will be described with reference to FIG.
Two positioning pins 44 are inserted into the openings 35 and 36. Here, in this embodiment, the two positioning pins 44 have the same diameter. One opening 35 provides play with respect to the positioning pin 44 to facilitate insertion of each positioning pin 44 into the openings 35 and 36. By positioning the positioning pin 44 into the openings 35 and 36, the seesaw button 40 and the seesaw main body 30 are positioned. Further, the seesaw button 40 is pushed into the seesaw main body 30 to bring the fitting claw 43 into the inner periphery. Fit into the space 34.
The outer peripheral rib 42 is disposed in the outer peripheral space 33, and the pair of recesses 45 are disposed in the pair of variable portions 32.
FIG. 6 shows the other surface of the seesaw body 31, and a push rib 37 that presses the switch 11 is formed on the seesaw body 31.

According to the seesaw button device configured as described above, when one side of the pressing portion 41 is pressed, a force is applied to one side of the seesaw main body 31 and the deflection generated in the variable portion 32 causes the seesaw main body. One side of 31 is displaced to the substrate 10 side. Due to the displacement of the seesaw body 31, the push rib 37 formed on one side of the seesaw body 31 presses one switch 11.
Further, when the center of the pressing portion 41 is pressed, even if a deflection occurs in the variable portion 32, any side of the seesaw body portion 31 is not displaced toward the substrate 10 side. Therefore, the two switches 11 are not pressed simultaneously.

As described above, according to the present embodiment, since the push rib 37 is formed on the escutcheon 20, it is not necessary to adjust the position of the seesaw button 40 and the switch 11, and the assemblability is improved.
In the present embodiment, the seesaw button 40 is disposed on the switch operating unit 30 with the pair of recesses 45 positioned on the pair of variable portions 32, so that the seesaw button 40 is mounted after the escutcheon 20 and the substrate 10 are assembled. The board 10 can be attached to the escutcheon 20 after the seesaw button 40 is attached to the escutcheon 20, and the pressing operation of the seesaw button 40 can be reliably transmitted to the seesaw body 31.
Further, in this embodiment, by forming the positioning pins 44 in addition to the fitting claws 43, it is possible to improve the workability of attaching the seesaw button 40 to the seesaw main body 31.
In the present embodiment, since one opening 35 is made larger than the other opening 36, it is possible to cope with a product error and to improve the mounting workability of the positioning pin 44.
Further, in this embodiment, the dimension between the two positioning pins 44 is made larger than the dimension between the pair of fitting claws 43, and the positioning pins 44 and the fitting claws 43 are arranged diagonally so as to be mounted. Workability can be improved and rattling after mounting can be reduced.
Further, in this embodiment, since the switch operation unit 30 is integrally formed with the escutcheon 20, it can be assembled only by adjusting the position of the escutcheon 20 and the substrate 10, so that the assemblability is improved.

  The present invention can be applied not only to audio equipment but also to various switches.
