Is provided in parallel with the adjacent third push button 530 and is positioned so as not to disturb the contact between the third contact 537 and the third sensor 540.

Accordingly, the third restoring means 550 prevents the third push button 530 from being rotated while the third push button 530 is operated as shown in FIG. After contact with the third sensor 540 serves to restore the third push button 530 to its original position.

On the other hand, as shown in Figure 8 the sensor is spaced apart around the bottom of the push button provided as follows.

As shown in FIG. 8A, a plurality of fourth contacts 582 are provided at the bottom edge of the fourth push button 580, and the fourth housing 570 is positioned opposite to the fourth contacts 582. A fourth sensor 595 may be provided on the bottom, and a fourth restoring means 590 may be provided between the fourth contact 582 and the fourth sensor 595.

In this case, when the fourth contact 582 of the fourth push button 580 pushes the fourth restoring means 590, the tip portion 594 of the fourth restoring means 590 is in contact with the fourth sensor 595. .

In addition, as illustrated in FIG. 8B, a plurality of fourth contacts 582 are provided at the bottom edge of the fourth push button 580, and a plurality of fourth contacts 582 are provided on the bottom of the housing, which is a position opposite to the fourth contacts 582.

The signal input device for an electronic product of the present invention as described above has an effect of inputting a plurality of signals to the electronic product using one push button.

In addition, by providing the shape of the restoring means in a narrow thin plate shape, the material cost can be reduced, and the sensor is connected to the push button by fixing the connection part of the restoring means to the housing and placing the tip part between the contact point and the sensor. It is possible to react, thereby improving the reactivity.

On the other hand, Figure 9 is a plan view and an exploded view showing a first modification of the push button of the present invention, Figure 10 is a plan view and an operation view showing a second modification of the push button of the present invention.

The first deformation pushing button 600 shown in FIG. 9 is composed of two crossing members 610 and 620 vertically intersecting with each other in the center, and the first deformation in which the two crossing members 610 and 620 are placed. The housing 700 is provided with a space having a “+” shape including a first space 710 and a second space 720 that vertically cross each other at a center inwardly.

The two intersecting members 610 and 620 are a first intersecting member 610 and a second intersecting member 620, and the first intersecting member 610 is placed in a first space 710 and a second intersecting member. The member 620 is placed in the second space 720.

The first cross member 610 is provided with a length and a width such that the first cross member 610 is moved back and forth only within the longitudinal direction of the first space 710, and the first cross member is formed at the center of the first cross member 610. The slot 612 long in the width direction of the 610 is formed.

In addition, the second cross member 620 vertically disposed below the first cross member 610 may protrude upward through the slot 612 and may move left and right along the slot 612. 622 is provided.

The width a of the second cross member 620 is equal to the width b of the center protrusion 622 and the width b of the slot 612, and the first space 710 and the first cross member 610. Width c is equal to the width d of the second space 720.

Therefore, the width c of the first cross member 610 is formed to be considerably larger than the width a of the second cross member 620, and the width a of the second cross member 620 is the second space ( Since it is very small compared to the width d of 720, the forward and backward movement of the first cross member 610 is considerably larger than the first push button 230 of FIG. 3.

In addition, since the first cross member 610 does not move together when the second cross member 620 moves, the horizontal movement of the second cross member 620 in the longitudinal direction is the length of the slot 612. As much as possible compared to the first push button 230 is significantly larger.
