  The second conductive member 20 is punched from a conductive plate material by punching, and the second contact portion 21 is formed into a flat plate shape. Further, as shown in FIGS. 4 and 6, the protruding portion 21 a is formed at the center of the second contact portion 21. The second conductive member 20 is formed by bending the end of the second contact portion 21 perpendicularly to the second contact portion 21 after the second contact portion 21 and the protruding portion 21a are formed.

After the second conductive member 20 is held by the holding member 30, the end portion of the second connecting portion 23 is bent vertically to form the second bent portion 23b shown in FIG. 2 The external connection part 22 is formed. After the first conductive member 10 is held by the holding member 30, the first bent portion 13b shown in FIG. 1 is formed by vertically bending the end portion of the first connecting portion 13 to form a first bent portion 13b. 1 The external connection part 12 is formed.

It has become.

  As shown in FIG. 6, when the switch device 1 is in a non-pressing operation, the second contact portion 21 is disposed to be opposed to the lower portion of the first contact portion 11 and is moved downward along with the pressing operation. It arrange | positions in the range which can displace the 1st contact part 11 to displace. In addition, the contact portion 31 is disposed below and spaced from the second contact portion 21, and is disposed within a displaceable range of the second contact portion 21 that is displaced downward in accordance with the pressing operation. The As shown in FIGS. 2 and 5, the first connecting portion 13 and the second connecting portion 23 move the first contact portion 11 and the second contact portion 21 in the vertical direction so as not to interfere with each other during a non-pressing operation. The circumference of the virtual center line A that penetrates is formed in the same direction in the clockwise direction and is arranged. Since it arrange | positions at intervals by planar view, the 1st connection part 13 and the 2nd connection part 23 become a structure which does not cross | intersect an up-down direction, when it deform | transforms by pressing operation.

  Next, with reference to FIGS. 6 to 8, an operation in which the first connecting portion 13 and the second connecting portion 23 generate a large upward elastic repulsive force in accordance with the pressing operation will be described. FIG. 7 is a schematic cross-sectional view of the switch device 1 cut along line II shown in FIG. 2 when the pressed first contact portion 11 comes into contact with the second contact portion 21. FIG. 8 is a schematic cross-sectional view of the switch device 1 cut along the line II shown in FIG. 2 when the second contact portion 21 comes into contact with the contact portion 31.

  As shown in FIG. 6, in the switch device 1, the first contact portion 11 and the second contact portion 21 are separated from each other during a non-pressing operation. An operator who operates the switch device 1 presses the first contact portion 11 from above along the virtual center line A. When the switch device 1 is operated to press the first contact portion 11 from above, the first conductive member 10 is distorted and displaced downward as a whole. In the first conductive member 10, at least a part of the first deformable portion 13 c is provided such that the vertical dimension is larger than the horizontal dimension in a sectional view in the vertical direction. Therefore, when the first contact portion 11 is displaced in the vertical direction by the pressing operation, the first conductive member 10 has a first fulcrum at both ends coupled to the first contact portion 11 and the first external connection portion 12. Since the connecting portion 13 is distorted so as to be twisted and elastically deforms in the vertical direction, a large upward elastic repulsive force is generated. At this time, an elastic repulsive force from the first conductive member 10 is transmitted as an operation load to an operator who presses the first contact portion 11 from above.

  When the switch device 1 is further pressed, as shown in FIG. 7, the first contact portion 11 that is pressed from above contacts the second contact portion 21. Moreover, after the 1st contact part 11 pressed from the upper part contact | abuts to the 2nd contact part 21, when the 1st contact part 11 is further pressed, the 1st conductive member 10, the 2nd conductive member 20, Are both displaced downward. The contact pressure generated between the first contact portion 11 and the second contact portion 21 is concentrated on the protruding portion 21a when the first contact portion 11 and the second contact portion 21 come into contact with each other. The formed oxide film is destroyed. In the second conductive member 20, at least a part of the second deforming portion 23 c is provided such that the vertical dimension is larger than the horizontal dimension in a cross-sectional view in the vertical direction. Therefore, when the first conductive member 10 and the second conductive member 20 are both displaced downward, the second conductive member 20 has both ends coupled to the second contact portion 21 and the second external connection portion 22. As the fulcrum, the second connecting portion 23 is distorted so as to be twisted and elastically deforms in the vertical direction, so that a large upward elastic repulsive force is generated. At this time, the combined force of the elastic repulsive force from the first conductive member 10 and the elastic repulsive force from the second conductive member 20 is transmitted as an operation load to the operator who presses the first contact portion 11 from above. The For this reason, an operation load becomes large.

  After the first conductive member 10 and the second conductive member 20 are both displaced downward, the switch device 1 is further operated by pressing the first contact portion 11, as shown in FIG. The part 21 comes into contact with the contact part 31. Due to the acting force exerted on the contact portion 31 by the second contact portion 21, a half acting force is generated from the contact portion 31. At this time, for the operator who presses the first contact portion 11 from above, the elastic repulsion force from the first conductive member 10, the elastic repulsion force from the second conductive member 20, and the reaction force from the contact portion 31 The resultant force is transmitted as an operation load. For this reason, the operation load becomes larger. As described above, the switch device 1 transmits a large operation load to the operator during operation.

  As described above, the switch device 1 according to the first embodiment of the present invention is formed of a conductive plate material, and is provided below the first contact portion 11 with the first contact portion 11 provided so as to be pressed from above. It is formed from a first conductive member 10 that includes a first external connection portion 12 that is provided, a first connection portion 13 that connects the first contact portion 11 and the first external connection portion 12, and a conductive plate material. A second contact portion 21, a second external connection portion 22 provided below the second contact portion 21, and a second connection portion 23 for connecting the second contact portion 21 and the second external connection portion 22. A second conductive member 20, and a holding member 30 that electrically separates and holds the first conductive member 10 and the second conductive member 20, and the first contact portion 11 and the second contact portion 21 are In the non-pressing operation, the first is arranged to face away from each other and pressed from above After the point part 11 comes into contact with the second contact part 21, both can be displaced downward, and the first connecting part 13 has a first deforming part 13c that is elastically deformed in accordance with the pressing operation, The second connecting portion 23 includes a second deforming portion 23 c that is elastically deformed in accordance with the pressing operation, and at least a part of the first deforming portion 13 c of the first connecting portion 13 and the second deforming portion of the second connecting portion 23. In at least a part of 23c, the vertical dimension is larger than the horizontal dimension in a cross-sectional view in the vertical direction. According to this, when the 1st contact part 11 displaces to an up-down direction by pressing operation, the 1st connection part 13 uses the both ends couple | bonded with the 1st contact part 11 and the 1st external connection part 12 as a fulcrum. As described above, a large elastic repulsive force is generated by elastic deformation in the vertical direction. Further, the second connecting portion 23 is coupled to the second contact portion 21 and the second external connection portion 22 when the first contact portion 11 displaced downward by the pressing operation comes into contact with the second contact portion 21. With the opposite ends as fulcrums, it elastically deforms in the vertical direction to generate a large elastic repulsive force. Since the combined force of the elastic repulsive force from the first conductive member 10 and the elastic repulsive force from the second conductive member 20 is transmitted to the operator who presses the first contact portion 11, the operation load increases. .

  Further, in the switch device 1 according to the first embodiment of the present invention, the holding member 30 can be brought into contact with the lower surface of the second contact portion 21 at the position facing the lower surface of the second contact portion 21. A contact portion 31 is provided. According to this, when the first contact portion 11 is pressed, it is displaced downward and comes into contact with the second contact portion 21. The second contact portion 21 that has come into contact with the first contact portion 11 is displaced downward and comes into contact with the contact portion 31 when the first contact portion 11 is further pressed. When the second contact portion 21 and the contact portion 31 come into contact with each other and an acting force is transmitted from the second contact portion 21 to the contact portion 31, a reaction force is generated. Therefore, the first contact portion 11 is pressed. The operation load applied to the operator's finger increases. Further, since the second contact portion 21 that is in contact with the contact portion 31 is restricted from being displaced downward, the contact pressure applied to the first contact portion 11 is increased, and the second contact portion 11 is electrically connected to the first contact portion 11. It becomes easy to do.
