  FIG. 1 is a plan view showing a switch device 1 according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view of the switch device 1 at the position of arrow AA in FIG. 1, and FIG. It is sectional drawing of the switch apparatus 1 in the position of the arrow BB in FIG. 2 illustrates a magnetic member 41 described later behind the cut surface, and FIG. 3 illustrates an input projection 211 of the operation unit 2 described later behind the cut surface (the same applies to other corresponding drawings). ). The switch device 1 is a thin push button switch, and is provided in various devices.

  As shown in FIGS. 2 and 3, the switch device 1 includes an operation unit 2, a support structure 3 that supports the operation unit 2 movably between a later-described steady position and a push-in position, and the operation unit 2. The position holding part 4 hold | maintained in a steady position and the detection part 5 which detects pushing to the pushing position of the operation part 2 are provided. In the switch device 1, the operation unit 2 can move in the vertical direction of FIGS. 2 and 3 (and the direction perpendicular to the paper surface of FIG. 1). In the following description, the vertical direction of FIGS. This is simply called the up-down direction. The vertical direction does not need to be parallel to the gravity direction, and may be parallel to the horizontal direction, for example.

  The operation unit 2 includes an operation unit main body 21 and an operation end 22 that is a side end of the operation unit 2. As shown in FIG. 1, the shape of the operation unit main body 21 when viewed along the vertical direction is a rectangle, and the operation end 22 is provided in an annular shape over the entire circumference of the operation unit main body 21. Specifically, as shown in FIG. 2, with respect to the vertical direction, the thickness of the operation end 22 is smaller than the thickness of the operation unit main body 21, and the operation end 22 protrudes outward from the side surface of the operation unit main body 21. To do. The lower surface of the operation end portion 22 and the lower surface of the operation portion main body 21 are located on the same plane. In other words, the operation unit 2 has a shape in which the upper part of the outer edge of the thick plate member is cut out. The operation part main body 21 and the operation end part 22 are formed with resin as one member, for example. The operation end 22 may be provided only on a part of the outer edge of the operation unit main body 21.

  The support structure 3 in the present embodiment is a case that accommodates the operation unit 2, and includes a side surface unit 31 that surrounds the side surface of the operation unit 2, and a bottom surface unit 32 that faces the lower surface of the operation unit 2 via the detection unit 5. Have A facing portion 33 that protrudes inward is provided at the upper end of the side surface portion 31 over the entire circumference. The facing portion 33 is located above the operation end portion 22 and faces the operation end portion 22 in the vertical direction. The side surface portion 31 is close to the outer edge of the operation end portion 22 over the entire circumference, and the inner edge of the facing portion 33 is close to the side surface of the operation portion main body 21 over the entire periphery. Thereby, the vertical movement of the operation unit 2 is guided by the support structure 3. The support structure 3 does not necessarily have a case shape, and may be a frame structure or the like.

  In the rectangular annular facing portion 33, the left and right linear portions 331 and 331 (hereinafter, both referred to as “facing linear portion 331”) in FIG. A plate-like magnetic member 42 extending along the shape portion 331 is provided. The magnetic member 42 is formed of a magnetic material such as iron. As shown in FIG. 3, a plurality of recesses 420 are formed on the lower surface of the magnetic member 42 along the longitudinal direction. The depths of the plurality of recesses 420 are constant, and an upper region 422 having a certain height, which is a set of bottom surfaces (upper surfaces) of the recesses 420, and an upper region 422 are formed on the lower surface of the magnetic member 42 in the vertical direction. A lower region 421 having a certain height (which may be regarded as a convex region), which is a set of regions to be excluded, is set. That is, unevenness is formed on the lower surface of the magnetic member 42.

  In addition, in the rectangular annular operation end portion 22, a plurality of (four in FIG. 3) magnetic members 41, for example, in the form of small blocks are formed on the upper surface of the operation line portion 221 that faces each opposing line portion 331. Is attached. Specifically, each of the plurality of magnetic members 41 is defined as a first attachment position on the upper surface of the operation linear portion 221 where each magnetic member 41 can be attached to face the lower region 421 of the magnetic member 42. It is attached at one attachment position. The fixing of the magnetic member 41 to the operation end portion 22 and the fixing of the magnetic member 42 to the facing portion 33 may be performed by a known method such as adhesion or press-fitting.

  The magnetic member 41 is a permanent magnet, and a magnetic attractive force is generated between the magnetic member 42 and the magnetic member 41. Therefore, in a steady state where the operator does not push in the operation unit 2, as shown in FIG. 3, the plate-like magnetic member 42 on each opposing linear portion 331 and the operation linear shape facing the opposing linear portion 331. The plurality of magnetic members 41 on the portion 221 are attracted. As described above, the operation unit 2 is held at the position shown in FIGS. 2 and 3 (hereinafter referred to as “steady position”) by the position holding unit 4 including the magnetic member 42 and the magnetic member 41. The magnetic member 42 may be a permanent magnet, and the magnetic member 41 may be magnetized by the magnetic member 42 to generate a magnetic attractive force therebetween. Further, both of the magnetic members 41 and 42 may be permanent magnets.

  The detection unit 5 includes, for example, a sheet-like tactile switch 51 provided in the support structure 3. As shown in FIGS. 4 and 5, when the operation unit 2 is pushed downward by the operator, the lower surface of the operation unit 2 comes into contact with the tactile switch 51, and the tactile switch 51 pushes the operation unit 2. Detected. Actually, the input protrusion 211 provided on the lower surface of the operation unit 2 contacts the tactile switch 51. In the following description, the position of the operation unit 2 with which the lower part comes into contact with the member below (in this case, the tactile switch 51) is referred to as a “push-in position”. The detection unit 5 may be other than a tactile switch, for example, a touch switch, a pressure sensor, or a Hall element or an electromagnetic induction sensor indicated by a two-dot chain line rectangle denoted by reference numeral 52 in FIG. (The same applies to other switch devices).

  As described above, in the steady state of the switch device 1, since the operation unit 2 is located at a steady position where the magnetic member 42 and the magnetic member 41 are attracted, the magnetism when the operation unit 2 is pushed into the push-in position. The gap width between the member 42 and the magnetic member 41 becomes the pushing amount (stroke amount) of the operation unit 2. As shown in FIG. 5, the magnetic member 41 faces the lower region 421 of the lower surface of the magnetic member 42 in the vertical direction, and the amount of pressing in the switch device 1 is between the lower region 421 and the upper surface of the magnetic member 41. Is the distance between. In FIG. 5, the pushing amount of the operation unit 2 is indicated by an arrow denoted by reference sign A1.

  In the switch device 1, when the operator presses the operation unit 2 and the suction between the magnetic member 42 and the magnetic member 41 is released, a click feeling is obtained by the operator. When the operator stops pushing the operating unit 2, the operating unit 2 returns to the steady position shown in FIGS. 2 and 3 by the magnetic attractive force acting between the magnetic member 42 and the magnetic member 41.

  On the other hand, when manufacturing the switch device 1 with different push-in amounts, the magnetic member 41 can be attached to the upper surface 422 of the plate-like magnetic member 42 on the upper surface of the operation line-shaped portion 221 (see FIG. 5). Each of the plurality of magnetic members 41 is attached to the second attachment position as shown in FIG. As a result, the gap width between the magnetic member 42 and the magnetic member 41 when the operation unit 2 is pushed from the steady position shown in FIG. 7 to the pushing position shown in FIG. As indicated by the arrow with the reference symbol A2, it is larger than the pushing amount A1 in FIG. In addition, in FIG. 1, the magnetic member 41 attached to the 2nd attachment position is shown with the dashed-two dotted line.

  It is also possible to change the force required to push the operation unit 2 in the switch device 1. Specifically, in the switch device 1 shown in FIG. 10, a smaller number of magnetic members 41 than in the switch device 1 shown in FIG. 3 are attached to the first attachment position. As a result, as shown in FIG. 11, when the operator pushes the operation unit 2 from the steady position to the pushed position, the force required to release the adsorption between the magnetic member 42 and the magnetic member 41 is the switch shown in FIG. It becomes smaller than the device 1. Similarly, a smaller number of magnetic members 41 than the switch device 1 shown in FIG. 3 may be attached to the second attachment position. As a result, when the operator pushes the operating unit 2 from the steady position to the pushed position, the force required to release the adsorption between the magnetic member 42 and the magnetic member 41 is smaller than that of the switch device 1 shown in FIG. The pushing amount of the operation unit 2 is also longer than that of the switch device 1 shown in FIG.

  As described above, in the switch device 1, the operation end 22 that is the side end of the operation unit 2 has the first attachment position and the second attachment position to which the magnetic member 41 can be attached, and the first attachment The position and the second attachment position are respectively opposed to the lower region 421 and the upper region 422 having different vertical heights (positions) on the lower surface of the plate-like magnetic member 42. Thereby, when the magnetic member 41 is attached to the first attachment position, the pushing amount, which is the gap width between the magnetic member 42 and the magnetic member 41 when the operation unit 2 is pushed into the pushing position, This is different from the case where the magnetic member 41 is attached to the second attachment position. As a result, in the switch device 1 in which a click feeling is generated, by changing the attachment position to which the magnetic member 41 is attached, it is possible to easily change the pushing amount of the operation unit 2 while using common parts.

  Further, the operation end portion 22 is provided with a plurality of first attachment positions. That is, the plurality of attachment positions at the operation end 22 include one first attachment position and the other first attachment position where the push-in amount when the magnetic member 41 is attached is the same. As a result, the number of magnetic members 41 can be changed, and the force required to push the operation unit 2 can be easily changed. Further, the operation end 22 is provided with a plurality of second attachment positions. In other words, the plurality of attachment positions at the operation end 22 include one second attachment position and the other second attachment position where the pushing amount when the magnetic member 41 is attached is the same. As a result, the force required to push the operating portion 2 can be easily changed in each of the two push-in amounts corresponding to the first attachment position and the second attachment position, respectively.

  In addition, when the magnetic member 41 is detachably attached to the operation end 22, the push amount of the operation portion 2 or the force required for push is changed not only at the time of manufacturing the switch device 1 but also the switch. You may perform in the state with which the apparatus 1 was mounted | worn with various apparatuses.

  FIG. 12 is a sectional view of a switch device 1a according to the second embodiment of the present invention, and corresponds to FIG. In the switch device 1a of FIG. 12, the structure of the operation unit 2 is different from that of the switch device 1 of FIG. The detection unit 5 includes a capacitive touch switch 51a. Other components are the same as those in FIG. 2, and the same components are denoted by the same reference numerals.

  In the operation unit body 21 of the operation unit 2, a relatively large input projection 211 a is provided on the lower surface. The cross-sectional area of the input projection 211a perpendicular to the vertical direction gradually decreases from the lower surface of the operation unit main body 21 downward. The operation portion main body 21 and the input projection 211a are formed of an elastic material such as conductive rubber. The touch switch 51a is a position input device capable of multipoint detection, and can be regarded as having a plurality of detection elements.

  When the operator depresses the operation unit 2, the adsorption of the magnetic member 42 and the magnetic member 41 is released, and as shown in FIG. 13, the operation is performed to the push position where the vicinity of the tip of the input projection 211a contacts the touch switch 51a. Part 2 moves. Thereby, pushing to the pushing position of the operation part 2 is detected by one detection element of the touch switch 51a. Subsequently, when the operator pushes the operation unit 2 with a larger force, the input projection 211a is mainly elastically deformed, and the operation unit is moved to the position shown in FIG. 14 (hereinafter referred to as “second push position”). 2 moves. As a result, the contact area between the input projection 211a and the touch switch 51a increases, and further pressing of the operation unit 2 is detected by another detection element close to the detection element in the touch switch 51a. The switch device 1a that detects the pushing position and the second pushing position of the operation unit 2 can be used, for example, for speed change (high speed and low speed change) during inching operation of a motor or the like.

  As described above, in the switch device 1a, the detection unit 5 has a plurality of detection elements, and when the operation unit 2 is pushed into the pushing position, the pushing of the operation unit 2 is one of the detection units 5. When the operation unit 2 is further pushed in, a part of the operation unit 2 is elastically deformed, and further pushing of the operation unit 2 is caused by another detection element of the detection unit 5. Detected. Thus, the switch device 1a implements a three-position switch that detects a two-stage pushing position. Further, similarly to the switch device 1 of the first embodiment, by changing the mounting position to which the magnetic member 41 is mounted, it is possible to easily change the pushing amount of the operation unit 2 while using common parts. it can. Furthermore, by changing the number of the magnetic members 41, it is possible to easily change the force required to push the operation unit 2.

  As will be described later, when a display device is provided on the lower side of the touch switch 51a, a transparent conductive sheet formed with a protrusion by embossing is used as a conductive operation unit body 21 (with a low elastic modulus). The operation unit 2 is formed by pasting it on the lower surface (the same applies to the example of FIG. 15). In this case, when the operation unit 2 is pushed into the push-in position, the projection of the transparent conductive sheet comes into contact with one detection element of the touch switch 51a, and when the operation unit 2 is further pushed in, the projection is elastic. It is deformed (collapsed) and comes into contact with detection elements around the detection element in the touch switch 51a. Of course, the operation part 2 may be formed as one member by transparent conductive rubber or the like. Moreover, the colored operation part 2 of FIG. 12 may be formed using the embossed conductive sheet.

  FIG. 15 is a diagram illustrating another example of the switch device 1a. In the switch device 1a of FIG. 15, a plurality of input protrusions 211a and 212 are provided on the lower surface of the operation unit main body 21 of the operation unit 2. With respect to the vertical direction, the height of each input protrusion 212 is smaller than that of the input protrusion 211a. When the operator depresses the operation unit 2, as shown in FIG. 16, the operation unit 2 moves to a depressing position where the vicinity of the tip of the input projection 211a contacts the touch switch 51a. Thereby, pushing to the pushing position of the operation part 2 is detected by one detection element of the touch switch 51a. Subsequently, when the operator pushes the operation unit 2 with a larger force, the input projection 211a is mainly elastically deformed, and the operation unit 2 moves to the second push position shown in FIG. Thereby, the vicinity of the tip of each input projection 212 is in contact with the touch switch 51a, and further pressing of the operation unit 2 is detected by another detection element close to the detection element. As described above, the push-in position in two stages can be detected also by the switch device 1a of FIG.

  Note that elastic members having different heights are provided at positions corresponding to the plurality of input projections 211a and 212 on the upper surface of the touch switch 51a (detection unit 5) in the switch device 1a of FIG. The plurality of input protrusions 211a and 212 may be omitted. In this case, when the operation unit 2 is pushed into the pushing position, the operation unit 2 comes into contact with the higher elastic member, and the pushing of the operation unit 2 is detected by one detection element of the detection unit 5. . When the operation unit 2 is further pushed in, the elastic member that is a part of the detection unit 5 is elastically deformed, so that the operation unit 2 comes into contact with the lower elastic member, and the operation unit 2 is further pushed in. Is detected by another detection element of the detection unit 5.

  18 is a plan view of a switch device 1b according to the third embodiment of the present invention, and FIG. 19 is a cross-sectional view of the switch device 1b at the position of arrow CC in FIG. In the switch device 1b of FIGS. 18 and 19, the structure of the operation unit 2 is different from that of the switch device 1 of FIG. The detection unit 5 includes a capacitive touch switch 51a similar to the switch device 1a of FIG. Other components are the same as those in FIG. 2, and the same components are denoted by the same reference numerals.

  A protrusion portion 213 that is long in the vertical direction of FIG. 18 is provided on the lower surface of the operation portion main body 21 of the operation portion 2, and the lower end of the protrusion portion 213 is sharp. Further, as shown in FIG. 19, an input projection 214 is provided in each of the left region and the right region of the projection 213 on the lower surface of the operation unit main body 21. In the operation unit 2, the operation unit main body 21, the projection 213, and the input projection 214 are formed as one member with, for example, resin.

  As shown in FIG. 20, when the operator pushes in the right region of the operation unit 2, the adsorption of the right magnetic member 42 and the magnetic member 41 is released. The vicinity of the tip of the projection 213 contacts the touch switch 51a, and the operation unit 2 tilts with the projection 213 as a fulcrum, and the right input projection 214 contacts the touch switch 51a. Thereby, pushing into the pushing position of the right side part of the operation part 2 is detected by one detection element of the touch switch 51a. When the operator releases the pushing of the operation unit 2, the operation unit 2 returns to the steady position by the magnetic attractive force acting between the magnetic member 42 and the magnetic member 41.

  When the operator pushes in the left area of the operation unit 2, the adsorption of the left magnetic member 42 and the magnetic member 41 is released. Then, with the projection 213 as a fulcrum, the operation unit 2 is inclined in a direction different from the above case, and the left input projection 214 comes into contact with the touch switch 51a. As a result, the pushing of the left portion of the operation unit 2 to the pushing position is detected by another detection element of the touch switch 51a.

  As described above, in the switch device 1b, the detection unit 5 includes a plurality of detection elements, and the protrusion 213 is provided on the lower surface of the operation unit 2. Then, when a part of the operation unit 2 is pushed in, the holding of the operation unit 2 by the position holding unit 4 is released, and the operation unit 2 is tilted with the protrusion 213 as a fulcrum, and the push-in is detected in the detection unit 5 It is detected by the detection element. In addition, when another part of the operation unit 2 is pushed in, the push-in is detected by another detection element of the detection unit 5 while the operation unit 2 is inclined in a different direction with the projection 213 as a fulcrum. The Thereby, the rocker switch of two notches can be realized in the switch device 1b that can easily change the push-in amount of the operation unit 2 using common components.

  In the switch device 1b, for example, one of the left magnetic member 41 and the right magnetic member 41 is attached to the first attachment position, and the other is attached to the second attachment position, so that the left region and the right side of the operation unit 2 are attached. The amount of push-in may differ depending on the area. In addition, by making the number of the left magnetic members 41 different from the number of the right magnetic members 41, the force required for pressing may be different between the left region and the right region of the operation unit 2. Further, a tactile switch or the like may be provided at a position facing each input protrusion 214. In this case, each switch can be regarded as a detection element of the detection unit 5 (same as in the second embodiment).

  In the switch device 1b, three or more notches may be set. For example, in the example of FIG. 21, the T-shaped protrusion 213 is provided, thereby realizing the three-notch switch device 1b. In the example of FIG. 22, the cross-shaped protrusion 213 is provided. A switch device 1b having four notches is realized. As described above, the switch device 1b that prevents the pressing of the operation unit 2 from being simultaneously detected in the plurality of detection elements of the touch switch 51a by providing the protrusion 213 can be realized in various modes. . Further, the protrusion may be provided at a position facing the lower surface of the operation unit 2 (for example, a position on the touch switch 51a). In this case as well, when a part of the operation unit 2 is pushed in, the operation unit When the other part of 2 is pushed in, it is possible to make the operation element 2 tilted in a different direction with the projection as a fulcrum, and to make the detection element from which the push is detected different.

  The switch devices 1, 1a, 1b can be variously modified. In the switch devices 1, 1 a, 1 b, the plate-like magnetic member 42 and the small block-like magnetic member 41 are provided on the facing portion 33 and the operation end portion 22, respectively, but the surface on which the concave portion 420 is formed faces upward. The magnetic member 42 may be fixed to the operation end 22 and the magnetic member 41 may be attached to the lower surface of the facing portion 33. Further, as shown in FIGS. 23 and 24, by shifting the position of the plate-like magnetic member 42, that is, by attaching the magnetic member 42 to different attachment positions, the gap width (pushing amount) between the magnetic members 42 and 41 is increased. ) May be changed.
