Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a small changeover switch device mounted on a narrow panel surface of a small electronic device.

[Conventional technology]

In recent years, electronic devices have become increasingly smaller, and as a result, panels have become narrower, and the components to be mounted have also become smaller. Smaller switches have smaller operating pins, making them difficult to operate. This tendency was particularly noticeable in a switch that has two contacts; when the operating pin is tilted in one direction, one contact closes, and when the operating pin is tilted in the other direction, the other contact is closed. Therefore, in order to improve operability, a lever was attached to the operation pin of a small switch and used.

[Problem that the invention attempts to solve]

Conventional switches like this have an operating pin,
When gluing the lever together, skill is required to adjust the height, direction, etc. of the lever, and the assembly process is inconvenient, requiring a large number of man-hours. Furthermore, since the lever is supported by a single operating pin, the lever operates in directions other than the operating direction of the lever, resulting in poor operability.

[Means for solving problems]

In order to solve the above-mentioned problems, the switch device of the present invention includes two push-button switches that are spaced apart from each other, and a switch that is provided near the operation section of the two push-button switches, and on the opposite side from the push-button switch. A support member having two recesses between the two push-button switches, a pressing part and a lever facing the two operating parts of the push-button switches are integrally formed, and the support member has a protrusion fitted into the recess of the support member. The device includes an operating member and a cover member having an opening through which a lever of the operating member projects.

[Effect]

When assembling the switch device of the present invention, the protrusion of the operating member is simply aligned with the recess in the support member, and the positioning of the support member and cover member when installing them is also done through the opening in the cover member. The lever of the operating member may be positioned at the center of the section. Further, since the operating member is supported from the supporting member by the two protrusions, the lever of the switch device of the present invention does not move at all in any direction other than the operating direction of the lever.

〔Example〕

FIG. 1 is an exploded perspective view of a preferred embodiment of the present invention, and FIG. 2 is a partially assembled sectional view taken along line - in FIG. 1. Two push button switches 10 and 11 are provided spaced apart on a printed board 12 fixed to a chassis or the like inside an electronic device. These two push-button switches 10, 11 have a function that when the operation parts 14, 15 are pressed, the switch goes down inside the push-button switches 10, 11 and closes the circuit of the push-button switches 10, 11. When you stop pressing the button, the closed circuit is no longer fixed in the same state, and the operation parts 14 and 15 are switched to the push button switch 1.
0,11 Lift up from inside, push button switch 10,
It has the ability to open 11 circuits. The two push button switches 10 and 11 are arranged on the printed board 12 so as to be spaced apart from each other in a straight line. Operation member 28
are made of insulating material, and the push button switches 10, 11
Pressing parts 22 and 23 provided at respective locations facing the respective operating parts 14 and 15, a lever 26 having a shape that is easy for humans to operate and having a finished surface, and cylindrical protrusions 24 and 25 are provided. It is integrally formed. The support member 20 is made of an insulating material, and has an opening 18 for surrounding the operating member 28, and an opening between the two push button switches 10 and 11 on the opposite side from the printed board 12.
The recesses 16 and 17 are formed with curved surfaces that support the cylindrical protrusions 24 and 25 and allow the cylindrical protrusions 24 and 25 to rotate smoothly. The cover member 30 has a flat panel member formed with an opening 32 through which the lever 26 projects. The lever 26 is attached to the support member 20 and the cover member 30
The protrusions 24 and 25 are placed in the recesses 16 and 17 in the direction of
Attach the support member 2 to the cover member 30 in a state that
0 is attached, for example with adhesive. The switch device of the present invention includes a combination of a support member 20, an operation member 28, and a cover member 30.
4, 15 and the pressing parts 22, 23 are in contact with each other,
It is fixed to the chassis or the like inside the electronic device using, for example, screws.

Now, when the lever 26 is tilted in the direction 42, the pressing part 22 presses the operating part 14, and the push button switch 1 is pressed.
Close the electrical circuit inside 0. On the other hand, move lever 26 to 4
When the switch is tilted in the direction 4, the push button 23 and the operating section 15 are pressed to close the electric circuit within the push button switch 11. By the way, the lever 26 is 42 or 4
In addition to when tilting in the direction 4, when returning from the tilted state, the pressing parts 22, 2 of the operating part 28
Since the levers 3 and 3 are both formed in an arc shape, they can smoothly slide on the surfaces of the operating parts 14 and 15 of the push button switches 10 and 11, thereby improving the operability of the lever 26. When no force is applied to the lever 26, the operating member 28 has protrusions 24, 25 that are connected to the recesses 16, 17 of the support member 20 and the cover member 3.
Since the pressing parts 22 and 23 are supported by the elastic force of the operating parts 14 and 15 of the push button switches 10 and 11, they are stable and will not wobble. In the illustrated embodiment, the support member 20 is a single member, but it is separated into two members, and one is used as a support member for the protrusion 24 of the operating member 28 near the recess 16 of the support member 20. Similarly, by separating the external force near the recess 17 of the support member 20,
It goes without saying that even if the support member for the protrusion 25 of the operating member 28 is modified, the effects of the present invention can be obtained.

[Effect of idea]

The switch device of the present invention has an extremely simple structure in which the operating member is placed on a support member at a predetermined position surrounding two push button switches, and a cover member is attached thereon to restrain the operating member.
By forming the concave portion of the support member that supports the operating member to be larger than the diameter of the protruding portion of the operating member, positioning during assembly work can be extremely facilitated and the number of assembly steps can be significantly reduced. Furthermore, by using an integrally formed operating member, parts costs can be reduced. Furthermore, according to the present invention, the support member supports the operating member at two points, completely eliminating unnecessary movement of the lever, thereby making it possible to significantly improve the operability of the lever.
