Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a switch mechanism in which a tact switch provided inside a case is operated by a button exposed on the surface of the case.

[0002]

[Prior Art]

 Conventionally, such a switch mechanism is configured as shown in FIG. 3, for example. That is, in FIG. 3, the switch mechanism 1 includes two tact switches 3 and 4 disposed inside the case 2 of various devices toward the surface of the case 2, and the tact switches 3 and 4. Of the switch pieces 5 and 6 provided on the inner side of the case 2 so as to face the knob portions 3a and 4a of the case 2 and the surface of the surface of the case 2 in a region corresponding to the switch pieces 5 and 6. It is composed of a rubber switch button 7 attached along with and has a waterproof structure.

The switch pieces 5 and 6 are pivotally mounted so as to be swingable around rotary shafts 5 a and 6 a, respectively, which are fixedly arranged with respect to the case 2. It has bosses 5b and 6b that project toward each other. The bosses 5b and 6b pass through the through holes provided in the case 2, and projecting parts 7a and 7a provided on the back surface of the switch button 7 are provided. It can come into contact with 7b.

According to the switch mechanism 1 configured as described above, by pressing the surface of the switch button 7 corresponding to the protruding portion 7a or 7b, the switch piece 5 located below the protruding portion 7a, 7b. When the boss portions 5b and 6b of the tact switches 3 and 6 are pushed downward, the switch pieces 5 and 6 are rotated around the rotary shafts 5a and 6a, and the knob portions of the tact switches 3 and 4 are rotated. This means that the tactile switches 3 and 4 can be operated by depressing 3a and 4a.

[0005]

However, in the switch mechanism 1 configured as described above, when the switch is operated, the switch pieces 5 and 6 are lowered while rotating around the rotation shafts 5a and 6a. The lower surfaces of the switch pieces 5 and 6 are moved because the lower surfaces of the switch pieces 5 and 6 are pushed downward by abutting the lower surfaces thereof on the knob portions 3a and 4a of the tact switches 3 and 4, respectively. When it comes into contact with the knob portions 3a and 4a of the tact switches 3 and 4, it comes into oblique contact with the upper surfaces of the knob portions 3a and 4a, so that the knob portions 3a of the tact switches 3 and 4 are brought into contact. , 4a cannot be smoothly pushed downward, and thus may malfunction, and there is a problem in that a clear click feeling cannot be obtained at the time of operation and therefore operability is not very good.

In view of the above points, the present invention provides a switch mechanism that can be reliably operated and provides a clear click feeling to improve the operability. Has a purpose.

[0007]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned object is such that inside the case, one side is provided inside the case so as to face the tact switch arranged toward the case surface and the knob portion of the tact switch. And a switch button made of rubber attached to the surface of the case in a region corresponding to the switch piece so as to come into contact with the switch piece along the surface of the switch piece. By pressing the surface of the switch button, the switch piece is rotated downward to press the knob portion of the tact switch and the switch mechanism is operated. The lower surface of the switch piece is provided with a protrusion, and when the switch piece is rotated downward, the lower surface of the protrusion is obliquely contacted with the upper surface of the knob portion of the tact switch. Success Characterized in that it is, by the switch mechanism, Ru is achieved.

[0008]

[Action]

 According to the above configuration, when the switch is operated, the switch piece moves downward while rotating around the rotary shaft, and the lower surface thereof abuts the knob portion of the tact switch, whereby the knob portion is moved. When the lower surface of the switch piece comes into contact with the knob portion of the tact switch, the lower surface of the protrusion provided on the lower surface of the switch piece is pressed against the upper surface of the knob portion. Surface contact, the knob portion of the tact switch can be smoothly pushed downward, so that the switch can be reliably operated and a clear click feeling can be obtained during operation. Therefore, the operability can be improved.

[0009]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of a switch mechanism according to the present invention.

The switch mechanism 10 includes two tact switches 12 and 13 arranged inside the case 11 of various devices toward the surface of the case 11 and knobs of the tact switches 12 and 13. The switch pieces 14 and 15 provided on the inner side of the case 11 so as to face the parts 12a and 13a, and the area of the surface of the case 11 corresponding to the switch pieces 14 and 15 along the surface thereof. It is composed of a rubber-made switch button 16 and has a waterproof structure.

The switch pieces 14 and 15 are pivotally mounted so as to be swingable around rotary shafts 14 a and 15 a that are fixedly arranged with respect to the case 11, respectively, and the switch pieces 14 and 15 are provided with an outward facing surface on the outside. The bosses 14b and 15b project toward the bosses 14b and 15b. The bosses 14b and 15b pass through the through holes provided in the case 11, and the protrusions 16a and 16b are provided on the back surface of the switch button 16. To be able to abut.

The above-mentioned configuration is similar to the conventional switch mechanism 1 shown in FIG. 3, but in the switch mechanism 10 according to the present invention, a protrusion is further provided on the lower surface of the switch pieces 14 and 15. 14c and 15c are provided, and the lower surfaces of the protrusions 14c and 15c of the knob portions 12a and 13a of the tact switches 12 and 13 when the switch pieces 14 and 15 are rotated downward. It is sloped so that it just makes surface contact with the top surface.

The switch mechanism 10 according to the present invention is configured as described above, and is positioned below the protrusions 16a and 16b by pressing the surface corresponding to the protrusion 16a or 16b of the switch button 16. The boss portions 14b and 15b of the switch pieces 14 and 15 are pushed downward, so that the switch pieces 14 and 15 are rotated around the rotation shafts 14a and 15a, and the tact switches 12 and 13 are rotated. The knobs 12a and 13a are pushed, and thus the tact switches 12 and 13 can be operated.

At that time, the switch pieces 14 and 15 move downward while rotating around the rotary shafts 14 a and 15 a, and the lower surfaces thereof are attached to the knob portions 12 a and 13 a of the tact switches 12 and 13, respectively. Although abutting, the lower surfaces of the protrusions 14c and 15c provided on the lower surface are formed obliquely, so that the lower surfaces of the protrusions 14c and 15c are the knob portions 12a and 13a of the tact switches 12 and 13, respectively. When it comes into contact with, the surface of the knob portion 12a, 13a is just in contact with the upper surface.

Therefore, since the knob portions 12a and 13a of the tact switches 12 and 13 can be smoothly pushed downward, there is no malfunction and the switch operation can be reliably performed. Since a clear click feeling can be obtained during operation, operability can be improved.
