Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push button structure for turning on and off two tact switches arranged in a cabinet, and more particularly to pushing two tact switches by pushing one push button. The present invention relates to a push button structure that can be used.

[0002]

2. Description of the Related Art Conventionally, in order to turn on and off two tact switches generally arranged in a cabinet, one tact switch is provided on the surface of the cabinet for each tact switch.
Each one had a push button. However, when the two push buttons are provided on the surface of the cabinet as described above, there is a problem that a large space is required in front of the cabinet.

Further, Japanese Utility Model Laid-Open No. 2-102634 discloses an operation knob device for electric equipment. This is as shown in FIGS. 2A and 2B.
In the operation knob device for a seesaw type electric device in which either one of the tact switches 131 and 132 mounted on the “0” can be selected by the seesaw movement of the seesaw knob 120, one end is a fixed end and the other end is a free end. And the first support arm 121
A second support arm 122 which is arranged in reverse to
An operation knob 120 having one end supported by the support arm 121 and the other end supported by the second support arm 122, and first and second spindles supporting the operation knob 120, respectively. A first notch 12 formed at one end of the operation knob 120 along a line connecting the fixed end of the first support arm 121 and the free end of the second support arm 122.
3A, 123B, a second notch 1 formed at the other end of the operation knob 120 along a line connecting the free end of the first support arm 121 and the fixed end of the second support arm 122.
24A and 124B, and when one end of the operation knob 120 is pressed, the operation knob 1 performs a rotational motion about the notch near the end due to deformation closer to the end than the notch of the pressed end, and the operation knob 1
20 is configured to be able to give an appropriate operation stroke.

In this case, two tact switches 131 and 132 provided vertically on a vertical printed circuit board 130 can be turned on / off, but they are provided horizontally on a printed wiring board arranged horizontally. There is a problem that the tact switch cannot be turned on / off. Further, since the operation knob 120 is formed to be long in the vertical direction, there is a problem that a large space is required in the vertical direction on the surface of a cabinet or the like in which the operation knob 120 is arranged.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and solves the above-described problem by using a single push button to move two or more cabinets together.
One tact switch can be turned on / off by pressing it, reducing the number of push buttons, saving space on the surface of the cabinet where the push buttons are arranged, and furthermore, It is an object of the present invention to provide a convenient push button structure in which only one tact switch can be turned on / off by pressing only one tact switch, or both tact switches can be turned on / off by pressing both at once.

[0006]

Means for Solving the Problems The present invention has been proposed to solve the above-mentioned problems, and the invention according to claim 1 has an operation piece extending horizontally toward the inside of a cabinet. A push button having a vertical piece provided integrally with the cabinet and having a hinge portion at an appropriate position in the vertical direction, and a button part integrally formed on the vertical piece and projecting outward so as to face the opening of the cabinet. A first tact switch mounted on an upper surface of a board in the cabinet and provided with a switch section facing upward, and a switch section mounted on a location near the back side of the first tact switch on the board so that the switch section faces horizontally. A second tact switch provided to face the operation side, and when the push button is slightly pressed, the vertically-oriented piece is slightly inwardly centered on the hinge portion. The press switch portion of the first tact switch in the lower surface of the tip portion of the operation piece falls down first
The tact switch is turned on, and when the push button is further pressed, the switch section of the second tact switch is pushed by the tip end surface of the operation piece to turn on the second tact switch. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a push button structure according to the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a push button structure according to an embodiment of the present invention.

As shown in FIG. 1, the push button structure of this embodiment has an operation piece 21 extending horizontally toward the inside of the cabinet 1 and a hinge 22 provided integrally with the cabinet 1 at an appropriate position in the vertical direction. A push button 2 having a vertically oriented piece 23 and a button portion 24 integrally formed with the vertically oriented piece 23 and projecting outward so as to face an opening 31 of a nameplate 3 provided on the outer surface side of the cabinet 1. And a switch unit 51 attached to the upper surface of the substrate 4 in the cabinet 1.
A first tact switch 5 provided upward, and a substrate 4
A switch section 61 is attached to a position near the back side of the first tact switch 5 on the upper side and provided horizontally to the operation piece 21 side, and a second tact switch 6 whose main body section is vertically oriented.

When the push button 2 is slightly depressed, the vertical piece 23 is slightly inclined inwardly around the hinge section 22 and the switch section of the first tact switch 5 is formed on the lower surface 21a of the tip of the operation piece 21. When the first tact switch 5 is turned on by pressing the button 51 and the push button 2 is further pressed, the second tact switch 6 is
, The second tact switch 6 is also turned on.

According to the push button structure of the present embodiment, two tact switches 5 and 6 in the cabinet 1 can be turned on and off by one push button 2, and the number of push buttons 2 can be reduced. In addition, space can be saved on the surface of the cabinet 1 where the push button 2 is disposed, and only the first tact switch 5 can be turned on / off by pressing the first tact switch 5 depending on the amount of pushing of the push button 2. Two first and second tact switches 5,
6 can be turned on and off by pressing both at once.

[0011]

As described above, the present invention relates to an operation piece extending horizontally toward the inside of a cabinet, a vertical piece provided integrally with the cabinet and having a hinge portion at an appropriate position in the vertical direction. A first push button having a button part integrally formed on a piece and projecting outward to face an opening of the cabinet, and a first tact attached to an upper surface of a substrate in the cabinet and provided with a switch part facing upward A switch, and a second tact switch, which is attached to a position near the back side of the first tact switch on the board and has a switch portion provided horizontally toward the operation side, and when the push button is slightly pressed, The vertical piece is slightly tilted inward with the hinge as the center, and the switch section of the first tact switch is pressed on the lower surface of the tip of the operation piece to turn on the first tact switch. , When you press a further push-button,
Since the second tact switch is turned on by pressing the switch of the second tact switch with the tip end surface of the operation piece, the following effects are obtained.

That is, two tact switches in the cabinet can be turned on / off by one push button, so that the number of push buttons can be reduced, and the surface of the cabinet in which the push buttons are arranged can be reduced. Can be turned on and off by pressing only one tact switch, or both can be turned on and off by pressing both tact switches at once, depending on the amount of push of the push button.
