Description

  The present invention relates to a multidirectional input device, and more particularly to a slide switch.

  There exists a thing illustrated in patent document 1 as a conventional multidirectional input device. The multi-directional input device of Patent Document 1 includes a housing having an opening at the top, an operating body protruding from the opening of the housing, and a support means for supporting the operating body so as to be slidable in multiple directions parallel to the bottom surface of the housing. And a plurality of slide detection means for detecting a slide direction of the operating body and outputting a detection signal. Each slide detecting means includes a sliding member provided to be slidable in a direction parallel to the bottom surface of the housing, a leaf spring for returning the position of the sliding member, and a fixed contact fixed to the inner wall of the housing. . The leaf spring is disposed so as to face the fixed contact with the longitudinal direction along the longitudinal direction of the inner side wall of the housing and the short side direction along the short side direction of the inner side wall of the housing. The leaf spring has conductivity, and the center of the leaf spring functions as a movable contact. Each movable contact moves in a direction parallel to the bottom surface of the housing in accordance with the deformation and return of the leaf spring including the movable contact, and contacts and separates from the fixed contact according to the position. When the operating body slides in a direction parallel to the bottom surface of the housing, the slide portion of the operating body presses the sliding member of any slide detecting means, whereby the leaf spring is bent and the movable contact contacts the fixed contact. (See FIGS. 1, 2, and 8 of Patent Document 1).

  Another conventional example is disclosed in Patent Document 2. The multi-directional input device of Patent Document 2 includes an insulating casing, a plurality of peripheral fixed contacts arranged annularly along the bottom surface of the casing, and a peripheral movable electrode that is a ring-shaped metal flat plate. And an operating body capable of tilting operation, and a dome-shaped peripheral pressing member that is curved from the central portion toward the peripheral portion. The peripheral movable electrode, which is a ring-shaped metal flat plate material, is arranged with its one surface facing the peripheral fixed contact with its inner peripheral edge supported by the housing. On the other surface side of the peripheral movable electrode, a peripheral pressing member whose central portion is supported by the operating body is disposed with its inner surface facing the bottom surface in the housing. When the operating body is tilted outward in an arbitrary radial direction, the peripheral pressing member supported by the operating body rotates in the operating direction. Due to this turning operation, the peripheral pressing portion, which is the peripheral portion of the peripheral pressing member, is displaced not only in the direction along the bottom surface of the casing but also in a direction substantially perpendicular to it (the thickness direction of the casing). The peripheral pressing portion of the peripheral pressing member thus moved contacts the peripheral movable electrode, and further continues to move so that the peripheral pressing portion moves the outer peripheral edge of the peripheral movable electrode in the thickness direction of the casing. The outer peripheral edge is brought into contact with the fixed contact for peripheral edge (see FIGS. 1, 11, and 12 of Patent Document 2).

  However, the conventional configuration has a problem in reducing the thickness of the product.

  In the configuration of Patent Document 1, a leaf spring and a fixed contact that are substantially perpendicular to the sliding direction of the sliding portion are arranged at a position on the inner wall side of the housing that is a sliding destination of the sliding portion, and the sliding portion is in the sliding direction. By pressing the leaf spring, the movable contact of the leaf spring is deformed in the sliding direction and brought into contact with the fixed contact. Here, when a leaf | plate spring is released from the press from a slide part, a leaf | plate spring will reset by the elastic force, and, thereby, the movable contact of a leaf | plate spring will leave | separate from a fixed contact (refer FIG. 2, 8 of patent document 1). . In order for the leaf springs to return reliably, the leaf springs must have the necessary elastic force, for example, the elasticity that returns to the pressing force, such as a click plate that is generally used as a leaf spring of a switch. It must have a structure with force (repulsive force). That is, a certain length is required also in the short direction of the leaf spring (in the thickness direction of the housing). This limits the thickness reduction of the product.

  Further, in the configuration of Patent Document 2, the peripheral movable electrode and the peripheral fixed contact are arranged to face each other in a posture along the bottom surface of the casing, and the peripheral pressing member is rotated as the operating body is inclined. The peripheral pressing portion moves in the direction along the bottom surface of the casing and in the thickness direction of the casing. Then, the peripheral pressing portion abuts on the peripheral movable electrode, and the peripheral peripheral electrode is deformed in the thickness direction of the casing by pressing the peripheral pressing portion in the thickness direction of the casing. The movable electrode for contact is brought into contact with the fixed contact for peripheral edge (see FIGS. 11 and 12 of Patent Document 2). In such a configuration in which the peripheral pressing member rotates, the peripheral pressing portion moves not only in the direction along the bottom surface of the casing but also in the thickness direction of the casing. The In addition, in such a configuration, when the allowable tilt range of the operating body is increased to increase the stroke of the peripheral pressing member, not only the size in the direction along the bottom surface of the casing of the product but also the casing. The size of the body in the thickness direction must also be increased. That is, in the configuration of Patent Document 2, the operation stroke cannot be increased without increasing the thickness of the product.

  Further, in the configuration of Patent Document 2, as the operating body is inclined, the peripheral pressing portion of the peripheral pressing member is moved from the inner peripheral edge side of the peripheral movable electrode supported by the supporting portion of the casing to the casing. The outer peripheral edge is deformed in the thickness direction of the casing by the peripheral pressing section that slides toward the outer peripheral edge that is not supported and reaches the outer peripheral edge of the peripheral movable electrode. The periphery is brought into contact with the fixed contact for periphery. In such a configuration, the peripheral pressing member rides on the inner peripheral edge of the peripheral movable electrode supported by the support portion of the housing, and the peripheral pressing portion of the peripheral pressing member is the outer peripheral edge of the peripheral movable electrode. The outer peripheral edge cannot be brought into contact with the fixed contact for peripheral edge unless it reaches the part (see FIGS. 11 and 12 of Patent Document 2). Thus, the thickness of a product will become thick in the structure which the edge pressing member rides on the site | part supported by the said support part.

  The present invention has been made in view of these points, and an object of the present invention is to provide a slide switch that can be made thinner than before.

  In the present invention, in order to solve the above-described problem, the base, a plurality of conductive fixed contacts fixed to the base in a posture facing a reference plane determined with respect to the base, and the base with respect to the base A slide portion that slides in a direction along a reference plane; a support portion that is disposed on the outer peripheral side of the slide portion and supported by the base; and extends from the support portion side to the slide portion side along the reference plane An elastic conductive member including a plurality of pusher portions, and a part of the outer surface of the pusher portion along the extending direction of the pusher portion is disposed to face any of the conductive fixed contacts. There is a conductive movable contact that is disposed on the opposite surface side so as to face the conductive fixed contact in a non-contact manner, and the slide portion slides in a direction along the reference plane. Abuts against any one of the pusher portions located at the slide destination, and further slides in the direction along the reference plane in this state, thereby elastically deforming the pusher portion, so that the conductive movable contact faces it. A slide switch is provided for contacting the disposed conductive fixed contact.

  Here, the conductive fixed contact of the present invention is arranged in a posture facing the reference plane, and the sliding direction of the slide portion is a direction along the reference plane. The conductive movable contact of the present invention exists on the outer surface side along the extending direction of the pusher portion extended along the reference plane. Therefore, in the present invention, the above-mentioned patent resulting from disposing a leaf spring (including a movable contact) and a stationary contact substantially perpendicular to the sliding direction of the sliding portion at a position to be a sliding destination of the sliding portion. There is no problem with the configuration of Document 1.

  In addition, the slide portion of the present invention slides in the direction along the reference plane, contacts one of the pusher portions, and further slides in the direction along the reference plane in this state to elastically deform the pusher portion. The conductive movable contact is brought into contact with the conductive fixed contact. Therefore, in this invention, the problem in the structure of the patent document 2 mentioned above resulting from the rotation of the peripheral pressing member (corresponding to the slide portion) does not occur.

  Moreover, the pusher part of this invention is extended from the support part side arrange | positioned at the outer peripheral side of the slide part and supported by the base to the slide part side along a reference plane. The slide portion of the present invention slides in a direction along the reference plane, thereby abutting against any one of the pusher portions located at the slide destination. In this state, the slide portion further slides in the direction along the reference plane. Therefore, in the present invention, the peripheral pressing member (corresponding to the slide portion) slides from the side supported by the support portion of the casing of the peripheral movable electrode to the side not supported by the casing. There is no problem with the configuration of Patent Document 2 described above.

  As described above, the slide switch of the present invention can be made thinner than before.

For example, the base 10 is made of insulating synthetic resin, rubber, or the like. It is a member formed integrally. A substantially rectangular plane region 10h is provided near the center of the inner bottom surface of the base 10 (the surface facing the open surface side of the base 10), and is further provided near the center at a position deeper than the plane region 10h. A circular planar region 10b is arranged. On the outer peripheral side of the planar area 10h, there are provided four substantially rectangular planar areas 10a and four approximately fan-shaped planar areas 10d surrounding the annular area. Each planar region 10a is disposed on the inner wall surface 10f side of the base 10, and each planar region 10d is disposed between adjacent planar regions 10a. Each planar region 10a, 10b, 10d, 10h and each support surface 10ca are, for example, substantially parallel to each other. Note that “substantially parallel” means a state of being completely parallel geometrically or a state within a predetermined permissible range (within a range permitted within the range where the effects of the present invention are exhibited). On each inner wall surface 10f side, a support portion 10c having a support surface 10ca substantially parallel to each planar region 10a is provided, and the arcuate outer periphery of each planar region 10d faces the inside of the base 10, respectively. A curved surface region 10e that is a concave surface substantially perpendicular to the planar region 10d is provided. Note that “substantially vertical” means a state that is geometrically completely vertical or a state within a predetermined allowable range (within a range that is allowed within a range that exhibits the effects of the present invention). The four curved surface areas 10e are arranged, for example, substantially on the circumference (substantially on a circle or substantially on an ellipse). In this embodiment, one virtual reference plane A determined with respect to the base 10 is assumed. In the present embodiment, for example, one plane that is substantially parallel to each of the planar regions 10a and 10b that are part of the inner bottom surface of the base 10 and that is positioned closer to the open surface side of the base 10 than the planar regions 10a and 10b is formed.

More specifically, the outer edge portion 16aa of the slide portion 16a contacts, for example, the first chamfered shape portion 15ae and the second chamfered shape portion 15ah of any of the pusher portions 15a located at the slide destination, By further sliding in the direction along the reference plane A while being in contact with the first and second chamfered shape portions 15ae and 15ah, the conductive fixed contacts 11a and the conductive fixed contacts 11a arranged to face the conductive movable contacts. The conductive movable contact of the pusher portion 15a is brought into contact with the conductive fixed contacts 11a and 11b. At this time, the slide portion 16a is displaced upward (in the direction of the inner plate 17), but the slide portion 16a comes into contact with the inner surface of the inner plate 17 by almost point contact, and the upward displacement is suppressed. Since it slides while being performed, it is possible to perform a smooth sliding operation. Thereby, the set of the conductive fixed contacts 11a and 11b is conducted through the pusher portion 15a, and the sliding direction of the slide portion 16a can be detected.

  Here, the conductive fixed contacts 11a and 11b of this embodiment are arranged in a posture facing the reference plane A, and the sliding direction of the slide portion 16a is a direction along the reference plane A. In addition, the conductive movable contact of the pusher portion 15a exists on the facing surface 15ab side along the extending direction of the pusher portion 15a extended along the reference plane A. Therefore, in this embodiment, the above-mentioned patent resulting from disposing a leaf spring (including a movable contact) and a fixed contact facing each other at a position to be a slide destination of the slide portion and a vertical spring substantially perpendicular to the slide direction of the slide portion. There is no problem with the configuration of Document 1, and the slide switch 1 can be thinned.

  Further, the slide portion 16a of the present embodiment slides in the direction along the reference plane A, abuts on any of the pusher portions 15a, and further slides in the direction along the reference plane A in this state, thereby the pusher portion 15a. Is elastically deformed to bring the conductive movable contact of the opposing surface 15ab into contact with the conductive fixed contacts 11a and 11b. Therefore, in this embodiment, there is no problem with the configuration of Patent Document 2 described above, which is caused by the rotation of the peripheral pressing member (corresponding to the slide portion), and the slide switch 1 can be thinned.

  Further, the pusher portion 15a of the present embodiment extends from the support portion 15aa side disposed on the outer peripheral side of the slide portion 16a and supported by the base 10 to the slide portion 16a side along the reference plane A. The outer edge portion 16aa of the slide portion 16a of the present embodiment slides in a direction along the reference plane A so as to come into contact with any one of the pusher portions 15a located at the slide destination. In this state, the outer edge portion 16aa further extends along the reference plane A. It moves to the back side of the opposing surface of the pusher part by sliding in the direction. Therefore, in this embodiment, the peripheral pressing member (corresponding to the slide portion) slides from the side supported by the support portion of the casing of the peripheral movable electrode to the side not supported by the casing. There is no problem with the configuration of Patent Document 2 described above, and the slide switch 1 can be made thinner.

  Further, since the elastic conductive member 15 is integrally formed, it is possible to reduce the number of parts and the number of assembly steps.

  As described above, in order for the outer edge portion 16aa of the slide portion 16a to elastically deform the pusher portion 15a and to bring the conductive movable contact of the opposing surface 15ab into contact with the conductive fixed contacts 11a and 11b, the pusher portion 15a It is necessary to slide the abutting slide portion 16a further in the direction along the reference plane A with a force equal to or greater than the first threshold value. Here, the slide portion 16a is slid in the direction along the reference plane A with the operation portion 16b inserted into the through hole 17a of the inner plate 17, but the slide portion 16a is moved to the reference plane A by the first threshold force. When the slide portion 16a is supported by the pusher portion 15a and / or the convex portion 15c, the outer peripheral side surface 16ba of the operation portion 16b is supported by the inner wall 17b of the through hole 17a of the inner plate 17. When the slide part 16a is slid in the direction along the reference plane A with a force greater than or equal to the second threshold value greater than the first threshold value, the outer peripheral side surface 16ba of the operation part 16b is The inner plate 17 abuts against the inner wall 17b of the through hole 17a and is supported by the inner plate 17 (see, for example, FIG. 11).

  Here, when the outer edge portion 16aa of the slide portion 16a that is in contact with the pusher portion 15a is slid in the direction along the reference plane A with a force not less than the first threshold value and less than the second threshold value, the opposing surface of the pusher portion 15a. The conductive movable contact 15ab contacts the conductive fixed contacts 11a and 11b, but the outer peripheral side surface 16ba of the operation portion 16b does not contact the inner wall 17b of the through hole 17a of the inner plate 17. Thereby, it can suppress that outer peripheral side surface 16ba of operation parts 16b, such as a synthetic resin, is shaved by inner wall 17b of penetration hole 17a of inner plate 17 which is a rigid body, and dust is generated with operation of operation part 16b. As a result, contact failure or the like caused by the dust generated in this way entering the base 10 can be suppressed.

  On the other hand, when the slide portion 16a is slid in the direction along the reference plane A with a force greater than the second threshold and greater than the second threshold, the outer peripheral side surface 16ba of the operation portion 16b is the inner wall of the through hole 17a of the inner plate 17. By supporting the inner plate 17 which is a rigid body in contact with 17b, a force more than necessary is applied to the pusher portion 15a and / or the convex portion 15c by the slide portion 16a, and the elastic conductive member 15 is detached from the base 10. Or the restoring force of the pusher portion 15a, the convex portion 15c and the like can be prevented from deteriorating.

  Further, as the operation of the slide switch 1, the operation unit 16 b is operated so that the axis of the operation unit 16 b of the slide member 16 moves in an annular manner along the reference plane A, and moves substantially on the circumference along the reference plane A. Thus, it is assumed that the slide part 16a is slid in such a manner that the conductive movable contacts on the opposing surface 15ab of each pusher part 15a are sequentially brought into contact with the respective conductive fixed contacts 11a, 11b facing each other (annular) operation). The elastic conductive member 15 of this embodiment includes an arm portion 15b made of an elastic body that connects adjacent pusher portions 15a, and a convex portion 15c that protrudes from the arm portion 15b along the reference plane A toward the slide portion 16a. Further, since the convex portion 15c is arranged on the outer peripheral side of the slide portion 16a and surrounds the outer peripheral side of the slide portion 16a in an annular shape, such an annular operation is smoother than in the case where the convex portion 15c does not exist. Can be done. In such an annular operation, the outer edge portion 16aa of the slide portion 16a can be brought into contact with not only the pusher portion 15a but also the convex portion 15c.

  Further, since the pusher portion 15a of the present embodiment includes the second chamfered shape portion 15ah provided at the edge portion on the side surface 15ag, 15af side of the first chamfered shape portion 15ae, the approximate circumference of the operation portion 16b is provided. Even when the outer edge portion 16aa of the slide portion 16a comes into contact with the pusher portion 15a from the side surfaces 15ag, 15af side or the side chamfered shape portions 15aj, 15ak side of the pusher portion 15a according to the above operation, the slide portion 16a. The outer edge portion 16aa smoothly sinks into the back surface 15ac side of each pusher portion 15a, and the conductive movable contact on the opposing surface 15ab of the pusher portion 15a can be brought into contact with the conductive fixed contacts 11a and 11b facing each other. Furthermore, since the side surface chamfered shape portions 15aj and 15ak are provided between the side surfaces 15af and 15ag of the pusher portion 15a and the tip portion 15ad of the pusher portion 15a, respectively, the above-described annular operation is performed. Can be done smoothly. Moreover, since the convex part 15c of this form is formed in the arm part 15b which consists of an elastic body, the outer edge part 16aa of the slide part 16a can be flexibly supported in the above-mentioned annular operation. Thereby, the above-mentioned annular operation can be performed smoothly.

  Preferably, when the conductive movable contact of the opposing surface 15ab of the pusher portion 15a contacts the conductive fixed contacts 11a and 11b, the slide portion that faces the slide direction of the slide portion 16a that is in contact with the pusher portion 15a. The outer edge part 16aa of 16a is located on the substantially circumference (for example, on E of FIG. 6) which passes along the front-end | tip part 15ca of the some convex part 15c. By setting the protruding amount of the convex portion 15c and the like so as to have such a configuration, a smoother circular operation is possible.

  More preferably, the sliding portion 16a that is in contact with the pusher portion 15a is slid in the direction along the reference plane A with a force that is greater than or equal to the first threshold value and less than the second threshold value. The outer edge portion 16aa of the slide portion 16a that faces the sliding direction of the slide portion 16a that contacts the pusher portion 15a when the contact contacts the conductive fixed contacts 11a and 11b is the tip portion 15ca of the plurality of convex portions 15c. Is located substantially on the circumference passing through (for example, on E in FIG. 6). Thereby, it can prevent that the outer peripheral side surface 16ba of the operation part 16b is scraped by the inner wall 17b of the through-hole 17a of the inner plate 17 which is a rigid body with the operation on the substantially periphery of the operation part 16b mentioned above.

  When the force applied to the operation portion 16b of the slide member 16 by the user is released, the return member 18 conducts the slide portion 16a with the central conductive fixed contact 12a by the elastic force of the elastic dome portion 18c. 9 is returned to a position on a straight line C passing through the movable movable dome 13 (a straight line C passing through the central conductive fixed contact and the central conductive movable contact) (FIG. 9).

  As described above, the slide portion 16a can be disposed on the straight line C, and the central conductive movable contact 13ba is disposed between the slide portion 16a disposed on the straight line C and the central conductive fixed contact 12a. . Then, by moving the slide portion 16a arranged on the straight line C to the central conductive movable contact 13ba side (D direction in FIG. 12), the central conductive movable contact 13ba is pressed to the central conductive fixed contact 12a side. Then, the central conductive movable contact 13ba and the central conductive fixed contact 12a come into contact with each other. Here, gaps exist between the slide portion 16a arranged on the straight line C and the plurality of pusher portions 15a, respectively. In other words, the slide portion 16 a arranged on the straight line C is not in contact with the elastic conductive member 15. Thereby, when the slide part 16a arranged on the straight line C is moved to the central conductive movable contact 13ba side (D direction in FIG. 12), the slide part 16a comes into contact with the pusher part 15a to face the pusher part 15a. It is possible to prevent the conductive movable contact 15ab from contacting the conductive fixed contacts 11a and 11b.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. This embodiment is a modification of the first embodiment, in which the elastic conductive member 15 does not have the convex portion 15c, but a convex portion is formed on the case.

It is arrange | positioned at the outer peripheral side of a slide part, and encloses the outer peripheral side of a slide part cyclically | annularly. Below, it demonstrates centering around difference with 1st Embodiment, and abbreviate | omits description about a common part. In each drawing, the same reference numerals as those in the first embodiment are used for portions common to the first embodiment.

  FIG. 13A is a perspective view of the base 20 of the second embodiment, and FIG. 13B is a perspective view of the elastic conductive member 25 of the second embodiment. FIG. 14 is a perspective view showing a configuration in which the top cover 19, the return member 18, and the inner plate 17 are removed from the slide switch of the present embodiment.

  The difference from the first embodiment is that the elastic conductive member 15 is replaced with the elastic conductive member 25 and the base 10 is replaced with the base 20.

  The base 20 of the second embodiment is an insulating member having a box-like shape with a substantially open cross section (FIGS. 13A and 14). For example, an insulating synthetic resin or rubber is used. It is the member formed integrally by. In the base 10 of the first embodiment, a curved surface region 10e that is a concave surface substantially perpendicular to the planar region 10e is provided near the four corners inside the base 10 and facing the inside of the base 10. However, in the base 20 of the second embodiment, the reference portions 20e arranged at a certain distance from the inner wall surface 20f are provided in the vicinity of the four corners inside the base 20, and the base of each reference portion 20e is provided. A surface facing the inner side of 20 is a convex portion 20ea that is a convex surface substantially perpendicular to the reference plane A (FIG. 13A). Each convex part 20ea of this form is each arrange | positioned on one substantially circumference (for example, F of FIG. 13) along the reference plane A, respectively. A support surface 20 ca that supports the elastic conductive member 25 is provided on the inner bottom surface along the reference plane A adjacent to the inner wall surface 20 f of the base 20. Other configurations of the base 20 are the same as those of the base 10 of the first embodiment.

  The elastic conductive member 25 of the second embodiment is a substantially rectangular annular integrally formed member made of an elastic conductive material such as conductive rubber (FIGS. 13 and 14). The elastic conductive member 25 includes a support portion 15aa supported by the support surface 20ca of the base 20, and a plurality of elastic conductive members 25 extending from the support portion 15aa side to the slide portion 16a side along the reference plane A (FIG. 13B and FIG. 14) includes four pusher portions 15a. Each pusher part 15a of this form is each formed in plate shape, tongue shape, etc., and the elastic conductive member 25 is arrange | positioned inside the base 20, and surrounds the outer peripheral side of the slide part 16a cyclically | annularly (FIG. 14). . The elastic conductive member 25 further includes an arm portion 25b made of an elastic body that connects adjacent pusher portions 15a. When the elastic conductive member 25 is disposed inside the base 20, each arm portion 25b is positioned and supported by the inner wall surface 20f, the reference portion 20e, and the support surface 20ca. Between the adjacent pusher portions 15a of the elastic conductive member 25 disposed inside the base 20, a relative position with respect to the base 20 is projected from the reference portion 20e fixed to the slide portion 16a side along the reference plane A. The convex portions 20ea are respectively arranged, and these convex portions 20ea are arranged on the outer peripheral side of the slide portion 16a and surround the outer peripheral side of the slide portion 16a in an annular shape. The function of each convex part 20ea is the same as the function of each convex part 10ea of the first embodiment. For example, when the conductive movable contact of the opposing surface 15ab of the pusher portion 15a contacts the conductive fixed contacts 11a and 11b, the outer edge of the slide portion 16a faces the slide direction of the slide portion 16a that contacts the pusher portion 15a. If the portion 16aa is positioned substantially on the circumference (for example, on F in FIG. 13) passing through the tips of the plurality of convex portions 20ea, the above-described annular operation can be performed smoothly.

Next, a third embodiment of the present invention will be described with reference to FIGS. The slide part of this embodiment includes a third chamfered shape part between the outer surface of the slide part along the slide direction and the outer edge part of the slide part facing the slide direction. Below, it demonstrates centering around difference with 1st Embodiment, and abbreviate | omits description about a common part. In each drawing, the same reference numerals as those in the first embodiment are used for portions common to the first embodiment.

<Configuration>
The difference from the first embodiment is that the slide member 16 is replaced with a slide member 36 and the elastic conductive member 15 is replaced with an elastic conductive member 35.

  The slide member 36 of the present embodiment includes a slide portion 36a that can slide in the direction along the reference plane A with respect to the base 10, and an operation portion 16b that protrudes on the one outer surface 16ab side along the slide direction. (FIGS. 15A and 15B and FIG. 17). The slide direction of the slide part 36a is, for example, all directions along the reference plane A. In the case of this embodiment, the slide member 36 is made of an insulating synthetic resin, rubber, or the like, and a disc-shaped slide portion 36a and a columnar operation portion 16b are integrally formed. The outer surface 16ab of the slide portion 36a and the outer surfaces 36ac, 16ad on the back side thereof are arranged along the reference plane A. Here, the outer surface 36ac of the slide portion 36a is an annular region located on the outer peripheral side of the outer surface 16ad, and the outer surfaces 36ac, 16ad are arranged in a posture facing the convex surface 14a side of the dome sheet 14. Further, the outer surface 16ab of the slide portion 36a is directed to the open surface side of the base 10, and the outer edge portion 36aa is directed to the sliding direction of the slide portion 36a. Further, the slide portion 36a of the present embodiment includes a third chamfered shape portion 36ae between the outer surface 36ac of the slide portion 36a along the slide direction and the outer edge portion 36aa of the slide portion 36a facing the slide direction. . For example, the slide portion 36a includes a third chamfered shape portion 36ae that is a flat or convex curved surface that is inclined or curved from the outer surface 36ac toward the outer edge portion 36aa.

  An elastic conductive member 35 made of an elastic conductive material such as conductive rubber is disposed on the outer peripheral side of the slide portion 36a of the slide member 36 (FIGS. 16B and 17). The elastic conductive member 35 includes a support portion 35aa supported by the support surface 10ca of the base 10 and a plurality of members (such as FIG. 16A) extended from the support portion 35aa side to the slide portion 36a side along the reference plane A. In the example, four pusher portions 35a are included. Each pusher part 35a of this form is formed in plate shape, tongue shape, etc., respectively, and encloses the perimeter side of slide part 36a annularly.

  In the elastic conductive member 35, as in the first embodiment, the support portions 35aa of the pusher portions 35a are supported by the support surfaces 10ca of the base 10, and the arm portions 15b arranged along the curved surface region 10e are planar regions 10d. It is arranged in the base 10 in a state where it is supported on the base 10. A part of the outer surface of the pusher portion 35a along the extending direction of each pusher portion 35a is a facing surface 35ab arranged to face any pair of the conductive fixed contacts 11a and 11b, and the facing surface 35ab It includes a conductive movable contact disposed so as to face the conductive fixed contacts 11a and 11b in a non-contact manner. In addition, the pusher portion 35a includes a back surface 35ac of the facing surface 35ab, a tip portion 35ad of the pusher portion 35a, and side surfaces 35af and 35ag along the extending direction of each pusher portion 35a. Further, the pusher portion 35a of this embodiment may also have a chamfered shape portion similar to the pusher portion 15a of the first embodiment, but in this embodiment, the slide portion 36a has a third chamfered shape portion 36ae. It is not always necessary to provide a chamfered shape portion on the pusher portion 35a. Other configurations of the elastic conductive member 35 are the same as those of the elastic conductive member 15 of the first embodiment, and the elastic conductive member 35 is an annular integrally formed member as in the first embodiment.

<Operation>
Next, the operation of the slide switch 3 according to the third embodiment will be described with reference to FIGS.

  The slide part 36a of the slide member 36 slides in the direction along the reference plane A according to the operation of the operation part 16b. As illustrated in FIGS. 17 to 19, when the slide portion 36 a slides in a direction along the reference plane A (for example, the direction B), the outer edge portion 36 aa or the third chamfered shape portion 36 ae of the slide portion 36 a is It abuts on one of the pusher portions 35a located at the slide destination. In this state, the slide portion 36a further slides in the direction along the reference plane A, so that the outer edge portion 36aa and the third chamfered shape portion 36ae of the slide portion 36a elastically deform the pusher portion 35a to face the opposing surface. The 35ab conductive movable contact is brought into contact with the conductive fixed contacts 11a and 11b arranged to face each other. More specifically, the slide portion 36a has the third chamfered shape portion 36ae brought into contact with the back surface 35ac side of the opposing surface 35ab of any of the pusher portions 35a located at the slide destination, and the third chamfered shape portion 36a. By further sliding the portion 36ae in the direction along the reference plane A while bringing the portion 36ae into contact with the back surface 35ac, the conductive fixed contact 11a disposed so as to face the conductive movable contact of the facing surface 35ab. The conductive movable contact is brought into contact with the conductive fixed contacts 11a and 11b. Thereby, the set of the conductive fixed contacts 11a and 11b is conducted through the pusher portion 35a, and the sliding direction of the slide portion 36a can be detected.

  As described above, since the third chamfered shape portion 36ae is provided in the slide portion 36a in this embodiment, the same effect as that of the first embodiment can be obtained without providing the chamfered shape portion in the pusher portion 35a. Similarly to the first embodiment, when the slide portion 36a is slid in an arbitrary direction along the reference plane A with the first threshold force, the slide portion 36a and the third chamfered shape portion 36ae are moved to the pusher portion 35a and the pusher portion 35a. By being supported by the convex portion 15c, the outer peripheral side surface 16ba of the operation portion 16b does not contact the inner wall 17b of the through hole 17a of the inner plate 17 (see, for example, FIG. 18), and the second larger than the first threshold value. When the slide portion 36a is slid in the direction along the reference plane A with a force equal to or greater than the threshold value, the outer peripheral side surface 16ba of the operation portion 16b abuts against the inner wall 17b of the through hole 17a of the inner plate 17 and is supported by the inner plate 17. (See FIG. 19, for example). Here, when the slide portion 36a that is in contact with the pusher portion 35a is slid in the direction along the reference plane A with a force that is greater than or equal to the first threshold value and less than the second threshold value, the conductivity of the opposing surface 35ab of the pusher portion 35a. Although the movable contact contacts the conductive fixed contacts 11a and 11b, the outer peripheral side surface 16ba of the operation portion 16b does not contact the inner wall 17b of the through hole 17a of the inner plate 17. Thereby, it can suppress that the outer peripheral side surface 16ba of the operation part 16b is scraped by the inner wall 17b of the through-hole 17a of the inner plate 17 which is a rigid body with operation of the operation part 16b. On the other hand, when the slide portion 36a is slid in the direction along the reference plane A with a force equal to or greater than the second threshold value that is greater than the first threshold value, the outer peripheral side surface 16ba of the operation portion 16b is the inner wall of the through hole 17a of the inner plate 17. By being supported by the inner plate 17 that is a rigid body in contact with 17b, an excessive force is applied to the pusher portion 35a and / or the convex portion 15c by the slide portion 36a, and the elastic conductive member 35 is detached from the base 10. It is possible to prevent the restoring force of the pusher portion 35a, the convex portion 35c and the like from being deteriorated. Other operations and features are the same as those in the first embodiment.
