Abstract

PURPOSE:To improve freedom in design by composing a push button of a lever swingable around a support part on a base side, and providing a manual operation part and a switch push operation part at two positions on one side with respect to a support part for the lever. CONSTITUTION:A push button 14 is composed of a lever swingable around a support part 15 on a base side, and at two positions on one side with respect to a support part 15 for the lever 16, a manual operation part 17 and a switch push operation part 18. It is thus possible to make differ a distance between the manual operation part 17 and the support part 15 from a distance between the switch push operation part 18 and the support part 15. Therefore, freedom in design is improved by making the manual operation stroke of the push button 14 and the switch push operation stroke, relatively differ larger.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pushbutton switch device.

[Prior Art] In general, push button switch devices are often used in telephones, office machines, audio equipment, and the like. A push button switch device consists of a switch that is fixed to the base and a switch that is movable to the base to turn on/off the switch.
The switch is configured to include a push button that is turned off.

[Problems to be Solved by the Invention] However, in the conventional push button switch device, the switch is installed directly below the push button, so the manual operation stroke of the push button and the switch pressing stroke are the same. There are many design and design constraints.

That is, in some switch devices, it is desirable to achieve a large switch push stroke with a small manual stroke, and in other switch devices, it is desirable to achieve a small switch push stroke with a large manual operation stroke. .

However, the conventional push button switch devices described above cannot meet these demands.

Incidentally, Japanese Utility Model Application Publication No. 63-108138 discloses a push button switch device that operates in a seesaw manner.

In this push button switch device, the push button is constituted by a lever that can swing around a support provided on the base side, a manual operation part is provided on one side of the lever with respect to the support part, and a manual operation part is provided on the other side of the lever. A switch pushing part is provided. However, even in this pushbutton switch device, the manual operating section and the switch pushing section are located on both sides of the supporting section, and the distance between the manual operating section and the supporting section and the switch pushing section are The distance between the moving part and the supporting part is set to be within a distance, and as a result, the manual operation stroke of the push button and the switch pressing stroke are within a distance.

An object of the present invention is to improve the degree of freedom in design by making the manual operation stroke of a push button and the switch pressing stroke relatively largely different.

[Means for Solving the Problems] The present invention includes a switch fixedly provided on a base, and a push button movably provided on the base for turning on/off the switch. In the push button switch device, the push button consists of a lever that can swing around a support provided on the base side, and a manual operation part and a switch pusher are located at two positions of the lever relative to the support part. It is configured to include a moving part.

[Function] In the pushbutton switch device of the present invention, the manual operation part of the pushbutton and the switch pushing part are located at two positions on one side of the support part with respect to the base, and the manual operation part or the support part is located at two positions. The distance between the switch pushing section and the supporting section can be made relatively large different from each other. Therefore, the manual operation stroke of the push button and the switch push stroke can be made relatively largely different, thereby increasing the degree of freedom in design.

[Example] FIG. 1 is a schematic diagram showing a first embodiment of the present invention, and FIG. 2 is a schematic diagram showing a second embodiment of the present invention.

(First Embodiment) FIG. 1 shows an example in which the present invention is applied to a response switch device 1o for a waterproof hands-free telephone installed in a bathroom or the like.

The switch device 10 has a switch 13 fixedly provided on a substrate 12 fixed inside a telephone case 11. Further, the switch device 1o has a push button 14 movable with respect to the case 11, and the switch 13 is turned on/off by the push button 14.

At this time, the push button 14 consists of a lever 16 that can swing around a support shaft 15 provided on the back surface of the case 11.
A manual operating section 17 and a switch pushing section 18 are provided at two positions on one side of the lever 16 with respect to the support shaft 15.

The distance that the manual operation unit 17 makes with respect to the support shaft 15 is I2a
, the distance between the switch pushing part 18 and the support shaft 15 is pb, and ρb/ρa 2.

At this time, since the switch device 10 is waterproof as described above, in order to seal the opening 19 of the manual operation section 17 in the case 11, the surfaces of the case 11 and the manual operation section 17 are covered with a waterproof sheet 2 degrees. It is P & overturned.

The push button 14 is configured to be restored to its original position by a restoring spring built into the switch 13 or a restoring spring provided around the support shaft 15.

Next, the operation of the first embodiment will be explained.

In the switch device 10 described above, the manual operation section 17 of the push button 14 and the switch pushing section 18 are located at two positions on one side of the support shaft 15 provided on the back surface of the case 11, and the manual operation section 17 distance β from the support shaft 15
a and the distance I2b that the switch pushing part 18 makes with respect to the support shaft 15 can be made relatively large different, such as pb/12a42. For this reason, pushbutton 1
4, the manual operation stroke sa and the switch push stroke sb are made relatively large different as in sb/5a42,
A large switch pushing stroke sb can be achieved with a small manual stroke sa. This means that when the waterproof sheet 20 is not highly elastic, even if the operating stroke (sb) of the switch 13 is large, the pushbutton 1
4 to ensure that the switch 13 is turned on/off,
This means that the degree of freedom in design can be improved.

(Second Embodiment) FIG. 2 shows an application of the present invention to a switch device 30 for a keypad 1 for an office machine. In FIG. 2, 31 is an office machine case, 32 is a board, 33 is a switch, and 34 is a push button.

At this time, the push button 34 consists of a lever 36 that can swing around a support shaft 35 provided on the back surface of the case 31.
A manual operating section 37 and a switch pushing section 38 are provided at two positions on one side of the lever 36 with respect to the support shaft 35 .

The distance that the manual operation unit 37 makes with respect to the support shaft 35 is ffa
, the distance between the switch pushing part 38 and the support shaft 35 is ρb, which is ρb/Ea valve 1/2.

Next, the operation of the second embodiment will be explained.

In the switch device 30, the manual operation section 37 of the pushbutton 34 and the switch pushing section 38 are located at two positions on one side of the support shaft 35 provided on the back surface of the case 31, and the manual operation section 37 distance β from the support shaft 35
a and the distance ρb between the switch pushing part 38 and the support shaft 35 can be made relatively large different, such as ρb/l2a41/2. For this reason, the manual operation stroke sa of the pushbutton 34 and the switch pressing stroke sb are made relatively large different, such as sb/sa#1/2,
A small switch pressing stroke sb can be realized with a large manual operation stroke sa. This means that switch 33
Even if the actuation stroke (s, b) is small, the switch 33 can be reliably turned on and off by providing a sufficient operational feeling to the push button 34, and the degree of freedom in design can be improved. means.

[Effects of the Invention] As described above, according to the present invention, the manual operation stroke of the push button and the switch pressing stroke can be made relatively largely different, thereby improving the degree of freedom in design.
