The installation location of the switch device is not restricted.

  Since such a self-powered switch device is a system that generates power by operating force from the outside, when the push button of the switch device is pushed, the push button is surely moved by a predetermined stroke and mechanical energy is It is necessary to generate self-power by electromagnetic induction, a piezoelectric element, etc. with this mechanical energy. In addition, the push button of the switch device needs to be designed with various designs and dimensions according to the application. However, since the switch devices of Patent Document 1 to Patent Document 3 do not have a structure in which the push button moves smoothly without being tilted regardless of the position on the pressing surface of the push button, the design of the push button There were restrictions on dimensions. In particular, it was not suitable for a switch device having a large pressing surface of the push button. In addition, it is necessary to appropriately set the force for pressing the push button according to the application. However, the switch devices of Patent Document 1 to Patent Document 3 have a structure in which it is easy to appropriately set the force for pressing the push button. Not done.

Support plates 54, 54 are integrally formed on the upper surface 21 </ b> B of the case 2, and both axial ends of the second shaft 53 are placed on the upper surfaces of the support plates 54, 54. The second shaft 53 is supported in parallel. In addition, columnar columns 55 and 55 are integrally formed on the upper surface 21B of the case 2 at both ends of the second shaft 53 in the axial direction, and the second shaft 53 is sandwiched from the left and right directions in FIG. Yes. A slight gap is formed between the columns 55 and 55 and the second shaft 53 in the left-right direction in FIG. A rectangular plate-like pressing plate 56 is fixed to the upper surfaces of the columns 55 and 55. The pressing plate 56 sandwiches the second shaft 53 lightly between the upper surfaces of the support plates 54 and 54. Therefore, the second shaft 53 is supported between the support plates 54 and 54 and the pressing plate 56 so as to be slightly movable in the left-right direction in FIG.

  As shown in FIGS. 4 and 6, both ends of the first shaft 51 and the second shaft 53 are connected by a first lever 57 and a second lever 58. The first lever 57 and the second lever 58 are attached orthogonally to the central axes of the first shaft 51 and the second shaft 53. The first shaft 51 is pivotally supported by the first lever 57 and the second lever 58 so as to be rotatable. The second shaft 53 is pivotally supported by the first lever 57 and the second lever 58 so as not to rotate. That is, a double-sided width shaft part (see FIG. 7) 531 in which both side surfaces of the cylindrical shaft are cut is formed at both ends of the second shaft 53, and the two-sided widths of the first lever 57 and the second lever 58 are formed. Engage with the groove. Therefore, when the push button 3 is pressed, the first shaft 51 is regulated with respect to the pressing surface 31A of the push button 3 by being regulated by the second shaft 53 that is always supported in parallel with the pressing surface 31A of the push button 3. It always maintains a parallel state and moves in a direction (vertical direction in FIG. 5) perpendicular to the pressing surface 31A of the push button 3.

  A switch 61 is fixed to the upper surface 21 </ b> B of the case 2. As shown in FIG. 5, a leaf spring 62 is attached to the switch 61, and the tip of the leaf spring 62 extends to below the first shaft 51. When the push button 3 is pushed and the first shaft 51 moves downward in FIG. 5, the first shaft 51 pushes down the tip of the leaf spring 62. When the leaf spring 62 is pushed down, a permanent magnet (not shown) of the switch 61 moves in the induction coil of the switch 61, and a current flows through the induction coil. That is, the switch 61 does not require a power source or a battery, and generates power by electromagnetic induction. With this self-generated current, the switch 61 transmits a radio signal to a receiver (not shown), and turns on and off electrical devices such as lighting. A push-up pin 71 is fixed to the upper surface 21 </ b> B of the case 2 immediately below the first shaft 51 and the leaf spring 62. The push-up pin 71 is constantly pushed upward in FIG. 5 by the compression coil spring 72 to push up the tip of the leaf spring 62. Accordingly, when the first shaft 51 is moved upward in FIG. 5 by releasing the hand from the push button 3, the push-up pin 71 pushes up the tip of the leaf spring 62, and as shown in FIG. The leaf spring 62 is returned to a state parallel to 31A.

  When the pressing surface 31A of the push button 3 of the switch device 1 configured as described above is pressed down, the slide pins 43 and 43 are pressed down. When the slide pins 43, 43 are pushed down, the links 41, 42 rotate around the slide pins 44, 44. In FIG. 7, the link 41 rotates counterclockwise around the slide pin 44. The link 42 rotates clockwise about the slide pin 44. When the link 41 rotates counterclockwise around the slide pin 44, the slide pin 43 of the link 41 moves to the left in FIG. 7 along the long groove 45, and the slide pin 44 of the link 41 moves along the long groove 46. Move to the right in FIG. When the link 42 rotates clockwise around the slide pin 44, the slide pin 43 of the link 42 moves to the right in FIG. 7 along the long groove 45, and the slide pin 44 of the link 42 moves along the long groove 46. To the left in FIG.

  When the links 41, 42 rotate around the slide pins 44, 44, the first shaft 51 is guided by the first guide members 52, 52, and is perpendicular to the pressing surface 31A of the push button 3 (FIG. 5). (Downward in FIG. 7). The first shaft 51 is regulated by the second shaft 53 and moves downward while maintaining a state parallel to the pressing surface 31 </ b> A of the push button 3. Accordingly, the first X link mechanism 4A and the second X link mechanism 4C operate synchronously, and the pressing surface 31A of the push button 3 moves downward while maintaining a state parallel to the lower surface 21A of the case 2. . That is, no matter which position on the pressing surface 31A of the push button 3 is pressed, the push button 3 moves smoothly downward without tilting, and the push button 3 moves reliably by a predetermined stroke. As shown in FIG. 9, when the push button 3 is pushed down, the compression coil springs 35, which are respectively arranged at the four corners, are compressed.

  When the push button 3 is pushed and the first shaft 51 moves by a predetermined stroke downward in FIG. 5, the first shaft 51 pushes down the tip of the leaf spring 62 as shown in FIGS. 8 and 9. When the leaf spring 62 is pushed down, a current flows through the induction coil of the switch 61, and the switch 61 transmits a radio signal to a receiver (not shown) to turn on and off electrical devices such as lighting. When the hand is released from the pressing surface 31 </ b> A of the push button 3, the push button 3 moves upward in FIG. 8 by the urging force of the compression coil spring 35 and returns to the state of FIGS. 5 to 7. Then, the push-up pin 71 is pushed upward in FIG. 8 by the compression coil spring 72, and the tip of the leaf spring 62 is pushed up to return to the state shown in FIGS.

  In the switch device 1 of the present invention, the push button 3 moves smoothly without being tilted regardless of the position on the pressing surface 31A of the push button 3, so that it is possible to design a push button having a design and dimensions according to the application. It becomes easy. In addition, by appropriately selecting the urging force of the compression coil spring 35, it is easy to adjust the force of pressing the push button 3 according to the application.

  Next, another embodiment of the present invention will be described with reference to the drawings. FIG. 10 shows another embodiment of the switch device of the present invention, and is a perspective view showing a state in which the switch device is turned over and the case and the switch are removed. As shown in FIG. 10, second guide members 38, 38 are integrally formed on the lower surface 31 </ b> B of the push button 3, sandwiching the first shaft 51 from both sides, and the axial direction of the first shaft 51. Guides both ends. In FIG. 10, only the second guide member 38 on one end side in the axial direction of the first shaft 51 is visible. The push button 3, the first X link mechanism 4A, and the second X link mechanism 4C are connected by slide pins 43 and 43 (see FIG. 7). The slide pins 43 and 43 are fitted in the long grooves 45 and 45, respectively. In addition, it is supported so as to be movable parallel to the pressing surface 31A of the push button 3. Therefore, there is a slight backlash between the push button 3 and the first X link mechanism 4A and the second X link mechanism 4C in a direction parallel to the pressing surface 31A of the push button 3.

  Therefore, when a switch device having a large push-down stroke of the push button 3 is designed, this play increases. As shown in FIG. 10, when the push button 3 is pushed down by providing the second guide members 38, 38, the first shaft 51 is moved to the first guide members 52, 52 on the case 2 side as described above. Is moved in a direction orthogonal to the pressing surface 31A of the push button 3. At the same time, the second guide members 38, 38 on the push button 3 side guided by the first shaft 51 move in a direction perpendicular to the pressing surface 31A of the push button 3, so that the push button 3 and the first X The play between the link mechanism 4A and the second X link mechanism 4C can be eliminated.

  As mentioned above, although the Example of this invention was described, this invention is not limited to this Example. For example, in the above-described embodiment, the first X link mechanism is provided via the side plates 37A and 37C of the upper guide plate 36 fixed to the push button 3 and the side plates 25A and 25C of the lower guide plate 24 fixed to the case 2. 4A and the second X link mechanism 4C are attached, but the first X link mechanism 4A and the second X link mechanism 4C are attached to the side plates 32A and 32C of the push button 3 and the side plates 22A and 22C of the case 2. You may attach directly. In the above-described embodiments, the push button and the case have a rectangular box shape. However, the push button and the case may have an arbitrary box shape such as a circular box shape or an elliptic box shape, or a half box shape.
