[Prior art]

 In the conventional switching device of this type, the button held on the operation panel is slid forward and backward, and the tip of the button pushes the contact to switch the contact. In this case, the timing at the time of turning on is not transmitted to the operator side, and it is not possible to determine whether or not the switch has been input, so it seems that the switch was not input even if it was intended to be pressed. There was a drawback that a mistake was made in the operation.

In order to solve this drawback, a switching device as shown in FIG. 5 has been proposed. Reference numeral 51 in the drawing denotes a button, and the button 51 includes a pressing surface 51a and a sliding portion 51b. Reference numeral 52 in the drawing denotes an operation panel, and the operation panel 52 has a support portion 52a for supporting the button 51. A spring 53 is wound around the sliding portion 51b that does not contact the supporting portion 52a when the pressing surface 51a is not pressed.

On the other hand, a substrate 55 is arranged behind the operation panel 52, and a tact switch 56 is arranged on the substrate 55 at a position where the tip of the sliding portion 51b can be pressed.

Button operations in the switching device configured as described above are performed as follows. When the pressing surface 51a is pressed with a finger or the like, the sliding portion 51b of the button 51 slides on the support portion 52a of the operation panel 52, and the button 51 moves to the inside of the operation panel 52. When the pressing surface 51a is pressed with a finger or the like, the tip of the sliding portion 51b presses the tact switch 56 provided on the substrate 55. When the tip of the sliding portion 51b presses the tact switch 56 provided on the substrate 55, this touch is transmitted to the operator's finger or the like, and it is determined that the switch input has been performed. When the operator releases the finger or the like from the pressing surface 51a after determining the switch input, the button 51 is returned to the original state by the biasing force of the spring 53.

[0006]

[Problems to be solved by the device]

 In the conventional switching device shown in FIG. 5, a tact switch 56 is provided for transmitting a switch input to the operator side. However, there is a problem that the addition of the tact switch 56 causes a cost increase as compared with a sheet or the like in which contacts are simply printed on the substrate 55.

In addition, when the tactile switch 56 and the like are provided, the height of the tactile switch 56 must be taken into consideration in designing, which increases the thickness of the switching device as a whole and causes a problem in designing. there were.

The present invention has been devised in view of the above problems, and an operator can easily determine that a switch has been input, and the cost does not increase. It is an object of the present invention to provide a switching device that can increase the degree of freedom.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the switching device according to the present invention has a board provided with contacts at the rear of the operation panel, and the button for pressing the contacts is slidable at a predetermined position in front of the contacts on the operation panel. A support portion that supports the inner surface of the button is formed, and an elastic deformable portion that is deformed by receiving a force from another member when the button moves rearward is formed on either the support portion or the button. Is characterized by.

[0010]

[Action]

 According to the above-described configuration, either the support portion of the operation panel or the button is formed with the elastically deformable portion that is deformed by receiving a force from another member as the button moves rearward. When the button is pressed, the elastically deformable portion comes into contact with another member at a position slightly before contacting the contact point, and when the button is pushed further, the elastically deformable portion escapes, The button is pushed inward. At this time, the resistance of catching by the elastically deforming portion of the button and the feeling of releasing the catch when overshooting are transmitted to the operator side via a finger or the like, and it is possible to judge that the switch has been input.

【Example】

 An embodiment of a switching device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic side sectional view showing a switching device according to an embodiment, and FIG. 2 is a rear perspective view showing a button. FIG. 3 is a schematic side sectional view showing the switching device when the button 11 is pressed.

Reference numeral 11 in the drawing denotes a button, and the button 11 is configured to include a pressing surface 11a and a sliding portion 11b. Two slits 11d are formed in the upper part of the sliding portion 11b, and the portion sandwiched by these slits 11d is an elastically deformable portion 11c. The tip of the elastically deformable portion 11c has a projection 11e having a slope 11f. Is formed. Reference numeral 12 in the drawing denotes an operation panel. The operation panel 12 is formed with a cylindrical support portion 12a for supporting the button 11, and the protrusion 11e of the button 11 is fitted into the support portion 12a. The hole 12b is formed. A spring 13 is interposed between the back surface of the pressing surface 11a and the support portion 12a of the operation panel 12.

On the other hand, a substrate 15 is arranged behind the operation panel 12, and the substrate 15 has contact points 14a and 14b provided therein.

A normal switching operation in the switching device configured as described above is performed as follows. When the pressing surface 11a is pressed with a finger or the like, as shown in FIG. 3, the sliding portion 11b moves to the substrate 15 side, and the elastically deforming portion 11c abuts the end surface of the hole 12b of the supporting portion 12a. At this point, the tip of the sliding portion 11b comes into contact with the contact 14a. When the pressing surface 11a of the button 11 is further pressed, the slanted surface 11f of the elastically deformable portion 11c is pressed down to the end of the hole 12b and the elastically deformable portion 11c is deformed, so that the tip of the sliding portion 11b is attached to the substrate 15. The contact point 14a is pressed and the contact point 14a and the contact point 14b are brought into pressure contact with each other, and the switch input is performed. At this time, the resistance received by the elastically deformable portion 11c from the hole 12b is transmitted to a finger or the like, and when the contact points 14a and 14b come into contact with each other, the resistance is released, and the operator side judges that the switch input has been made. You can When the operator judges that the switch input is performed due to the decrease in the resistance, and the finger or the like is released from the pressing surface 11a, the button 11 is retracted from the substrate 15 by the urging force of the spring 13, and the elastic deformation portion 11c is formed in the hole 12b. , And the button 11 returns to the position shown in FIG.

As described above, in the switching device according to the embodiment, since the elastically deformable portion 11c is formed on the sliding portion 11b of the button 11, when the pressing surface 11a is pressed, the elastically deformable portion is pressed. 11c contacts the end surface of the hole 12b of the support portion 12a of the operation panel 12, and the elastically deformable portion 11c deforms so that the tip of the sliding portion 11b contacts the contact point 14a. It can be judged that the switch input has been made by the resistance received by and the release of the resistance.

FIG. 4 is a side sectional view schematically showing a switching device according to another embodiment. Reference numeral 21 in the drawing denotes a button, and the button 21 is configured to include a pressing surface 21a and a sliding portion 21b. Reference numeral 22 in the drawing denotes an operation panel. The operation panel 22 is provided with a support portion 22a for supporting the button 21. The support portion 22a is elastically abutted against the pressing surface 21a of the button 21 at the front end thereof. A plurality of elastically deforming portions 22b that are deformed are formed. A spring 13 is provided between the back surface of the support portion 21a and the support portion 22a.

On the other hand, a substrate 15 is arranged behind the operation panel 22, and the substrate 15 has contact points 14 a and 14 b therein.

A normal switch input operation in the switching device configured as described above is performed as follows. When the pressing surface 21a is pressed with a finger or the like, the sliding portion 21b moves to the substrate 15 side, and the end portion of the pressing surface 21a abuts the inclined surface 22c of the elastically deforming portion 22b. When the pressing surface 21a of the button 21 is further pressed, the elastic deformation portion 22b is deformed by the pressing surface 21a, the pressing surface 21a enters the inside of the support portion 22a, and the tip of the sliding portion 21b contacts the contact point 14a of the substrate 15. Then, the contact point 14a and the contact point 14b come into pressure contact with each other, and switch input is performed. At this time, the resistance that the end of the pressing surface 21a abuts the elastically deforming portion 22b is transmitted to a finger or the like, and when the tip of the sliding portion 21b abuts the contact 14a, the resistance is released, and the operator does not receive a switch input. It can be judged that it was done. When the operator judges that the switch input has been made by releasing the resistance and releases the finger or the like from the pressing surface 21a, the button 21 retracts from the substrate 15 by the biasing force of the spring 13 and the sliding portion 21b contacts. The button 2 1 returns to its original position after being released from 14.

As described above, according to the above-described embodiment, since the elastic deforming portion 22b is formed on the support portion 22a of the operation panel 22, when the pressing surface 21a is pressed, the end portion of the pressing surface 21a is elastic. When the deforming portion 22b is contacted and the pressing surface 21a is further pressed 21, the elastically deforming portion 22b is deformed and the tip of the sliding portion 21b comes into contact with the contact point 14a. It can be judged that the switch input is made by the change.

In addition, in the elastically deformable portions 11c and 22b, the elastically deformable portions 11c and 22b may be made thinner than the other portions in order to have elasticity. Further, although the elastically deforming portion 11c is formed at one place in the above embodiment, the invention is not limited to this, and the elastically deforming portion 11c may be formed at a plurality of places.

[0022]

As described above in detail, in the switching device according to the present invention, the substrate having the contacts is arranged at the rear of the operation panel, and the contact is provided at a predetermined position in front of the contacts of the operation panel. An elastic deformation is formed in which a supporting portion that slidably supports the pressing button is formed, and the supporting portion or the button is deformed by receiving a force from another member as the button moves rearward. Since the portion is formed, when the button is pressed, the elastically deformable portion is deformed, and the operator side must judge that the switch input is performed by the change in resistance transmitted to the finger or the like. You can Therefore, the operator side can always accurately judge that the switch has been input, and can prevent an erroneous operation. In addition, since it is not necessary to add extra components such as a tact switch to prevent erroneous operation, there is no increase in cost, and there is no height restriction, etc., and the degree of freedom in design can be increased. .
