[0005] Patent Document 1: International Publication No. 2019 / 230079 Summary of the invention

[0006] Problems to be solved by the invention

[0007] In a switch device, the connection state is switched by moving the movable contact member relative to the switching contact member, so the relative positional relationship between the switching contact member and the movable contact member is important for performing a reliable switching operation. Therefore, the movable contact member and its holding member are integrally formed by insert molding, but a structure is desired in which the relative positions of the switching contact member and the movable contact member are easily and reliably aligned without using insert molding.

[0008] An object of the present invention is to provide a switch device capable of easily and reliably aligning the relative positions of a switching contact member and a movable contact member.

[0009] Means for solving problems

[0010] A switch device according to one embodiment of the invention comprises: a switching contact member having at least two contacts; a common contact member; a movable contact member disposed between the switching contact member and the common contact member and capable of electrically connecting the switching contact member to the common contact member; and a holding member that holds the movable contact member, and by moving the movable contact member relative to the switching contact member, switching between a first connection state and a second connection state can be performed, wherein in the first connection state, a direction along the moving direction of the movable contact member is set as a first direction, a direction along the direction extending from the movable contact member and perpendicular to the first direction is set as a second direction, and a direction perpendicular to the first direction is set as a second direction. When the directions orthogonal to the two directions of the second direction are set as the third direction, the movable contact component comprises: a main body; a pair of contact pieces, which are arranged on the main body, extend along the second direction, and are arranged in the third direction in a manner capable of clamping the switching contact component; and a common contact portion, which is arranged in a portion of the main body that is different from the portion where the pair of contact pieces are arranged, and contacts the common contact component. The holding component comprises a receiving portion that can receive the received portion of the main body. Through the snap fit between the received portion and the receiving portion, the holding component allows a specified displacement of the main body in the third direction and limits at least one of the displacement in the first direction and the displacement in the second direction.

[0011] According to such a configuration, the displacement of the main body relative to the holding member is restricted by the snap fit between the received portion of the main body and the receiving portion of the holding member. In the snap fit, the direction in which the main body moves relative to the holding member for the snap fit is orthogonal to the direction in which the received portion moves when it is received in the receiving portion by the snap fit. Therefore, since the third direction is irrelevant to a series of actions for the snap fit, the main body can be displaced in the third direction relative to the holding member even if the snap fit is performed.

[0012] In the switch device described above, the holding member may further include a slit portion, which limits the displacement of the main body portion in the moving direction of the accommodated portion when the accommodated portion is accommodated in the accommodating portion, and in a state where the insertion portion, which is a portion of the main body portion different from the accommodated portion, is inserted into the interior of the slit portion, the accommodated portion and the accommodating portion are snap-fitted, so that the displacement of the main body portion in the first direction and the displacement of the main body portion in the second direction relative to the holding member are limited. In this way, by performing snap-fitting in a state where the insertion portion is inserted into the slit portion and the displacement of the main body portion in the moving direction of the accommodated portion is limited, the possibility of the accommodated portion being detached from the accommodating portion can be reduced.

[0013] In the switch device described above, the direction of movement of the received portion when the received portion is snap-fitted into the receiving portion may be along the first direction. Thus, the movement of the movable contact member in the second direction is restricted by the snap-fitting.

[0014] In the switch device described above, the direction of movement of the received portion when the received portion is snap-fitted into the receiving portion may be along the second direction. Thus, the movement of the movable contact member in the first direction is restricted by the snap-fitting.

[0015] In the switch device, the switch device may also be configured to have a force-applying structure, which applies force when the received portion and the receiving portion are snap-fitted, so that the received portion and the receiving portion are in elastic contact. In this way, when the received portion and the receiving portion are in elastic contact, a force exceeding the friction force based on the elastic contact is required to displace the received portion in the receiving portion. As a result, the main body is not displaced relative to the retaining member even if it is subjected to a slight vibration, thereby avoiding contact instability due to vibration.

[0016] In the switch device described above, the accommodated portion and the accommodating portion may be configured to elastically contact each other along a first direction. Since the urging direction is along the first direction, the influence of sliding resistance during switch operation is suppressed.

[0017] In the switch device, the holding member may include a plurality of receiving portions, the main body may include a plurality of received portions corresponding to the plurality of receiving portions, and the main body may be restricted from displacement in the first direction and displacement in the second direction relative to the holding member by snap-fitting the plurality of received portions with the corresponding receiving portions. In this way, the main body may be held relative to the holding member by snap-fitting.

[0018] In the switch device, the holding member may include a limiting portion that limits the range of displacement of the movable contact member relative to the holding member in the third direction. Since the movable contact member can be displaced in the third direction, the limiting portion limits the range of displacement in the third direction, thereby suppressing separation in the third direction.

[0019] In the switch device, the restricting portion may be formed of an intervening portion located in a gap between the pair of contact pieces in the third direction, and the displacement of the movable contact member in the third direction is restricted by the intervening portion contacting the contact piece.

[0020] In the switch device, the force-applying structure may include: a convex portion provided on the retaining member; and a snap-fitting piece provided on the main body and connected to the received portion, wherein the convex portion is snap-fitted with the received portion when the received portion is snap-fitted to the receiving portion, and the convex portion is snap-fitted with the snap-fitting piece, and elastic deformation of the snap-fitting piece caused by the convex portion occurs, and the received portion connected to the snap-fitting piece is force-applied in the first direction by the elastic deformation. Thus, the received portion is force-applied in the first direction during the snap-fitting, and the shaking of the movable contact member in the first direction after the snap-fitting is suppressed.

[0021] In the switch device, the convex portion may have an inclined surface, and the engaging piece may slide on the inclined surface as the received portion moves when the received portion is snap-fitted to the receiving portion, thereby increasing the degree of elastic deformation of the engaging piece. As a result, the force acting on the engaging piece as the received portion moves during the snap-fitting is increased.

[0022] In the switch device, the main body may be elastically deformed first when the received portion and the receiving portion are snap-fitted. Thus, the main body is elastically deformed first compared to the received portion during snap-fitting, making snap-fitting easier.

[0023] In the switch device, the movable contact member may be made of a metal material having elasticity. When the movable contact member is made of a metal material having elasticity, the main body is easily and preferentially elastically deformed during snap-fitting.

[0024] In the switch device described above, the holding member may hold a plurality of movable contact members arranged in a third direction. The holding member may hold a plurality of movable contact members, thereby improving redundancy of the switch operation.

[0025] In the above switch device, the switching contact member may have two contact portions independent of each other, the first connection state is a first conduction state in which one of the two contacts is electrically connected to the movable contact member, and the second connection state is a second conduction state in which the other of the two contacts is electrically connected to the movable contact member. Thus, the switching between the first conduction state and the second conduction state is performed by switching the contact between the movable contact member and the two contact portions.

[0026] In the above-mentioned switch device, the switch device may include a snap action mechanism, and the first connection state and the second connection state may be switched instantaneously by the snap action mechanism.

[0027] In the switch device, the first connection state may be a conductive state in which the movable contact member is electrically connected to the contact, and the second connection state may be a non-conductive state in which the contact is not electrically connected.

[0029] According to the present invention, it is possible to provide a switch device capable of easily and reliably performing relative position alignment between a switching contact member and a movable contact member. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are given to the same components, and the description of components that have been described once will be appropriately omitted.

[0063] (Overview of switchgear)

[0064] Figure 1 This is a perspective view of the appearance of a switch device according to one embodiment.

[0065] Figure 2 is a side view of a switch device according to an embodiment.

[0066] Figure 3is a top view of a switch device according to an embodiment.

[0067] Figure 4 It is an exploded perspective view of a switch device according to an embodiment.

[0068] In the following description, for convenience, the Z1-Z2 direction in the figure is set as the Z-axis direction (up and down direction), the X1-X2 direction in the figure is set as the X-axis direction (front and back direction), and the Y1-Y2 direction in the figure is set as the Y-axis direction (left and right direction). In addition, the Z-axis direction is taken as an example of the "first direction", the X-axis direction is taken as an example of the "second direction", and the Y-axis direction is taken as an example of the "third direction".

[0069] like Figures 1 to 3 As shown, the switch device 100 includes a housing 110 , a slider 130 , and a bracket 150 . The housing 110 is a hollow structure with an upper opening and has a rectangular parallelepiped shape. The upper opening of the housing 110 is closed by a flat plate-shaped cover 112 .

[0070] like Figure 4 As shown in the figure, a circular opening 112A for the slider 130 to pass through is formed in the cover 112. A columnar shaft support 112B is provided downwardly on the lower surface of the cover 112. A first shaft 112C having a bent front end and convex downward is formed at the lower end of the shaft support 112B. The first shaft 112C abuts against an upper bearing surface 161A of a first actuator 161 provided in the movable unit 160, thereby axially supporting the first actuator 161 from the upper side of the first actuator 161 so as to be rotatable.

[0071] The slider 130 is a generally cylindrical component that is pressed and operated. The slider 130 is provided through the opening 112A of the cover 112, and a portion thereof is provided to protrude upward from the upper surface of the cover 112. The slider 130 is provided to be slidable in the vertical direction (Z-axis direction) relative to the housing 110.

[0072] The switch device 100 can switch the conduction state by pressing the slider 130. Specifically, the switch device 100 is in the first connection state when the slider 130 is not pressed. Furthermore, the switch device 100 switches to the second connection state when the slider 130 is pressed. The first connection state may be the first conduction state, and the second connection state may be the second conduction state, or the first connection state may be the conduction state and the second connection state may be the non-conduction state.

[0073] The bracket 150 is an annular member covering the upper surface of the cover 112 and surrounding the slider 130. The bracket 150 has a pair of hooks 152 hanging downward from the outer peripheral edge thereof. The bracket 150 is mounted on the housing 110 by engaging each of the pair of hooks 152 with each of the pair of claws 114 provided on a pair of mutually parallel side surfaces of the housing 110. Thus, the bracket 150 fixes the cover 112 to the housing 110. For example, the bracket 150 is formed by processing a metal plate.

[0074] (Switch Device Configuration)

[0075] The switch device 100 is configured to include a bracket 150, a cover 112, a slider 130, a movable unit 160, and a housing 110. Figures 1 to 3 In addition to the structure described in the above, the housing 110 is also provided with Figure 4 The movable unit 160 is shown.

[0076] The housing 110 has a space 110A with an upper opening. A portion of the lower side (Z2 side) of the slider 130 and the movable unit 160 are accommodated in the space 110A. For example, the housing 110 is formed by injection molding using a relatively hard insulating material (for example, hard resin).

[0077] The movable unit 160 is formed by combining a plurality of movable members and is actuated by the up-and-down movement of the slider 130 in response to the pressing operation, and switches the switch device 100 between the first connection state and the second connection state by snap action.

[0078] The movable unit 160 includes a switching contact member 170 , a movable contact member 165 , and a holding member 166 .

[0079] Figure 5 It is a perspective view of a holding member and a movable contact member.

[0080] Figure 6 This is a perspective view showing the holding member and the movable contact member in an upside-down manner (rotated 180 degrees about the X-axis).

[0081] like Figure 5 as well as Figure 6 As shown, the movable contact member 165 and the holding member 166 are arranged to be movable relative to the switching contact member 170. For example, the movable contact member 165 and the holding member 166 are swingably supported by the housing 110, and are arranged to slide relative to the switching contact member 170 by the up-and-down movement of the slider 130 accompanying the pressing operation.

[0082] The base member 180 formed of an insulating material is provided with at least two contacts (first contact 171, second contact 172) of the switching contact member 170, a common contact member 173, and a terminal 175. The two contacts (first contact 171, second contact 172) of the switching contact member 170 and the common contact member 173 are respectively connected to one of the plurality of terminals 175. When the movable unit 160 is accommodated in the space 110A of the housing 110, the plurality of terminals 175 are arranged to be exposed from the bottom surface of the housing 110.

[0083] The movable contact member 165 is disposed between the switching contact member 170 and the common contact member 173, and is provided so as to be able to electrically connect the switching contact member 170 to the common contact member 173. The two contacts (the first contact 171 and the second contact 172) of the switching contact member 170 are disposed to be separated from each other in the Z-axis direction, and the electrical connection between the common contact member 173 and any one of the two contacts (the first contact 171 and the second contact 172) is switched by the movable contact member moving (e.g., sliding) between the two contacts (the first contact 171 and the second contact 172) in the Z-axis direction (the first direction).

[0084] For example, the state in which movable contact member 165 is in contact with first contact 171 is a first connection state in which first contact 171 is electrically connected to common contact member 173 via movable contact member 165. On the other hand, the state in which movable contact member 165 is in contact with second contact 172 is a second connection state in which second contact 172 is electrically connected to common contact member 173 via movable contact member 165. The switching of the connection state is performed by the up-and-down movement of slider 130 accompanying the pressing operation.

[0085] The movable contact member 165 that switches the connection state is held by a holding member 166 formed of an insulating material. The holding member 166 is supported to be swingable relative to the housing 110, and the connection position of the movable contact member 165 relative to the switching contact member 170 is switched by the swing.

[0086] The movable contact member 165 has a main body 165C extending along the X-axis direction (the second direction), a pair of contact pieces 165A, and a common contact portion 165B. The pair of contact pieces 165A are provided at one end side (the X1 side in the X1-X2 direction) of the main body 165C, extend along the X-axis direction, and are arranged side by side in the Y-axis direction (the third direction) in a manner that can clamp the switching contact member 170. The common contact portion 165B is a portion that contacts the common contact member 173, and is provided at a portion of the main body 165C that is different from the portion where the pair of contact pieces 165A are provided (for example, the other end side (the X2 side in the X1-X2 direction)) of the main body 165C. The common contact portion 165B may also have a pair of clamping pieces 165Ba. The pair of clamping pieces 165Ba of the common contact portion 165B are arranged side by side in the Y-axis direction in a manner that can clamp the common contact member 173.

[0087] The movable contact member 165 is formed by, for example, stamping a metal material having elasticity. The movable contact member 165 is formed of a member different from the holding member 166 formed of an insulating material and is assembled to the holding member 166. A plurality of movable contact members 165 may be mounted on one holding member 166.

[0088] In this embodiment, two movable contact members 165 are arranged side by side in the Y-axis direction on the holding member 166. In addition, two switching contact members 170, a common contact member 173, and a terminal 175 are also provided corresponding to each movable contact member 165. By providing two movable contact members 165, etc. in one holding member 166, the redundancy of the switch action is improved. In addition, the movable contact member 165, etc. provided in one holding member 166 is not limited to two, and can be one, or can be three or more.

[0089] (Holding member and movable contact member)

[0090] Figure 7 This is an exploded perspective view of the holding member and the movable contact member.

[0091] Figure 8 This is a diagram for explaining the attachment of the movable contact member to the holding member.

[0092] Fig. 9 It is a cross-sectional view showing a state where the movable setting member is held by the holding member.

[0093] In addition, Figures 7 to 9 , for the sake of convenience of explanation, the relationship between the retaining member 166 and one movable contact member 165 is shown.

[0094] The retaining member 166 has a receiving portion 166D capable of receiving the received portion 165D of the main body 165C of the movable contact member 165. In the present embodiment, for example, a convex received portion 165D protruding in the second direction (X1-X2 direction X2 direction) is provided at the end of the common contact portion 165B side of the main body 165C, and a concave received portion 166D capable of receiving the received portion 165D is provided in the retaining member 166. Furthermore, the received portion 165D of the main body 165C is configured to snap-fit ​​with the receiving portion 166D of the retaining member 166. Figures 7 to 9 As shown, the storage portion 166D is recessed toward the Z1 side of the Z1-Z2 direction more than the surrounding portion (specifically, the portion on the X2 side of the X1-X2 direction). Therefore, when the movable contact member 165 moves toward the X1 side of the X1-X2 direction, the stored portion 165D enters the recess, that is, moves toward the Z1 direction of the Z1-Z2 direction and is stored in the storage portion 166D. Thus, the retaining member 166 allows the main body 165C to move in the Y-axis direction and restricts the displacement in the X-axis direction. Specifically, when the main body 165C is displaced toward the X2 side of the X1-X2 direction, the stored portion 165D contacts the step on the X2 side of the X1-X2 direction formed by the storage portion 166D, and thus further displacement of the main body 165C to the X2 side of the X1-X2 direction is restricted.

[0095] The holding member 166 further includes a slit portion 166E that restricts the displacement of the main body 165C in the moving direction of the accommodated portion 165D when the accommodated portion 165D is accommodated in the accommodation portion 166D. An insertion portion 165E is provided at a portion of the main body 165C different from the accommodated portion 165D, and the insertion portion 165E is inserted into the interior of the slit portion 166E.

[0096] The gap in the Z-axis direction of the slit portion 166E is set to have a thickness substantially the same as the thickness of the insertion portion 165E. Figure 8 As shown, when the insertion portion 165E moves to the X1 side of the X1-X2 direction and is inserted into the slit portion 166E, the displacement of the main body 165C connected to the insertion portion 165E in the Z-axis direction is restricted. In addition, since the X1 side of the X1-X2 direction of the slit portion 166E is closed, the further displacement of the main body 165C in the X1-X2 direction X1 side is restricted by the contact between the insertion portion 165E and the slit portion 166E. Furthermore, in the state where the insertion portion 165E is inserted into the slit portion 166E, when the received portion 165D connected to the main body 165C is snap-fitted with the receiving portion 166D, as described above, the displacement of the main body 165C to the X2 side of the X1-X2 direction is restricted. In this way, the displacement of the main body 165C in the Z-axis direction and the displacement in the X-axis direction relative to the retaining member 166 are restricted.

[0097] In order to make the movable contact part 165 and the retaining part 166 snap-fit, as shown in FIG. Figure 7 as well as Figure 8 As shown, the main body 165C of the movable contact member 165 is placed on the mounting surface 166A of the holding member 166 while the holding member 166 is turned upside down, and the main body 165C is slid forward (in the X1-X2 direction X1 direction) (refer to Figure 8 ). Thus, the insertion portion 165E provided in the main body portion 165C is inserted into the slit portion 166E.

[0098] Then, with the insertion portion 165E inserted into the slit portion 166E, the received portion 165D of the main body 165C is pressed into the receiving portion 166D of the holding member 166 to fit in. Since the movable contact member 165 is formed of a metal material having elasticity, the main body 165C is elastically deformed first, and thus the received portion 165D is embedded in the receiving portion 166D. Thus, the movable contact member 165 and the holding member 166 are snap-fitted.

[0099] In this embodiment, in the snap fit, the direction (X-axis direction) in which the main body 165C moves relative to the holding member 166 for the snap fit is orthogonal to the moving direction (Z-axis direction) of the received portion 165D when received in the receiving portion 166D by the snap fit. Therefore, the Y-axis direction is irrelevant to a series of actions for the snap fit, and the main body 165C can be displaced in the Y-axis direction relative to the holding member 166 even when the snap fit is performed.

[0100] Here, the movable contact member 165 is in elastic contact so as to clamp the switching contact member 170 and the common contact member 173 in the Y-axis direction. That is, the pair of contact pieces 165A of the movable contact member 165 are in elastic contact with the contacts to clamp the contacts (the first contact 171 and the second contact 172) of the switching contact member 170, and the pair of clamping pieces 165Ba of the movable contact member 165 are in elastic contact with the common contact member 173 to clamp the common contact member 173. Therefore, if the relative positions of the movable contact member 165, the switching contact member 170, and the common contact member 173 in the Y-axis direction are offset, the stress balance of the pair of pieces (the pair of contact pieces 165A and the pair of clamping pieces 165Ba) of the movable contact member 165 is destroyed.

[0101] As in the present embodiment, the retaining member 166 is configured to allow the main body 165C of the movable contact member 165 to be displaced in the Y-axis direction and to retain the movable contact member 165. Therefore, even if the relative positions of the movable contact member 165, the switching contact member 170, and the common contact member 173 in the Y-axis direction are offset, the movable contact member 165 can self-adjust and move in the Y-axis direction in accordance with the positions of the switching contact member 170 and the common contact member 173, thereby suppressing the destruction of the stress balance of a pair of sheets.

[0102] Furthermore, even if the movable contact member 165 and the holding member 166 are formed of different members instead of being integrally formed by insert molding, they can be combined by snap-fitting, so that even different members can be easily manufactured.

[0103] In the snap fit, a force-applying structure 190 may be provided, which applies force to elastically contact the received portion 165D with the receiving portion 166D when the received portion 165D and the receiving portion 166D are snap-fitted. In the present embodiment, as a specific example, the force-applying structure 190 includes: a convex portion 166F provided on the retaining member 166; and a snap-fitting piece 165F provided on the main body 165C and connected to the received portion 165D. The convex portion 166F has an inclined surface 166Fa, and the snap-fitting piece 165F slides on the inclined surface 166Fa as the received portion 165D moves toward the receiving portion 166D when the received portion 165D is snap-fitted, thereby forming a structure in which the degree of elastic deformation of the snap-fitting piece 165F is increased.

[0104] Specifically, when the main body 165C is slid in the X-axis direction (X1 direction X1 direction) with the insertion portion 165E inserted into the slit portion 166E, the engaging piece 165F extending from the main body 165C in the Y-axis direction sneaks under the convex portion 166F (under the state where the holding member 166 is turned upside down), and as the main body 165C is slid forward (X1 side in the X1-X2 direction), the engaging piece 165F slides along the inclined surface 166Fa and gradually presses down the engaging piece 165F. As a result, the degree of elastic deformation of the engaging piece 165F increases, and accordingly, the received portion 165D of the main body 165C is forced in the Z-axis direction (Z1 direction Z1 direction). Soon, the received portion 165D and the receiving portion 166D are snap-fitted, and the elastic contact state of the received portion 165D and the receiving portion 166D is maintained.

[0105] When the received portion 165D and the receiving portion 166D are in elastic contact, a force exceeding the friction force due to the elastic contact is required to displace the received portion 165D in the receiving portion 166D. Thus, even if subjected to some vibration, the main body 165C does not displace relative to the holding member 166, thereby avoiding contact instability due to vibration.

[0106] In addition, the received portion 165D and the receiving portion 166D may also be in elastic contact along the Z-axis direction. Since the force direction of the force-applying structure 190 is along the Z-axis direction, the influence of the sliding resistance during the switch operation is suppressed (the movable contact member 165 is subjected to a force in a direction away from the retaining member 166, and the movable contact member 165 becomes unstable).

[0107] In addition, the holding member 166 may also be configured to include a limiting portion 200 that limits the range of displacement of the movable contact member 165 in the Y-axis direction relative to the holding member 166. The limiting portion 200 may also be configured to include a clamping portion 210 that is located in the gap in the Y-axis direction between the pair of contact pieces 165A. For example, the clamping portion 210 is provided on the side surfaces 166B (surfaces orthogonal to the mounting surface 166A) on both sides of the mounting surface 166A of the main body 165C in the Y-axis direction. A bent portion 165Aa is provided between the pair of contact pieces 165A of the movable contact member 165 and the main body 165C, and the bent portion 165Aa is bent from both sides of the main body 165C in the Y-axis direction toward the Z-axis direction (Z1-Z2 direction Z1 direction).

[0108] When the movable contact member 165 is snap-fitted with the retaining member 166, the bent portion 165Aa is configured to cover the outer side of the side 166B of the retaining member 166. A gap is provided in the Y-axis direction between the bent portion 165Aa and the side 166B. The limiting portion 200 is constituted by the bent portion 165Aa and the side 166B, and the movement of the movable contact member 165 in the Y-axis direction relative to the retaining member 166 is limited to the amount of the gap in the Y-axis direction between the bent portion 165Aa and the side 166B. In addition, as another example of the specific structure of the limiting portion 200, a structure in which a recess is provided on one of the main body 165C and the retaining member 166, and a convex portion provided on the other side is loosely fitted into the recess can be cited.

[0109] (Snap-fit ​​form)

[0110] FIG. 10A to FIG. 14B It is a schematic diagram illustrating a form of snap fit.

[0111] exist Fig. 10AIn the snap-fitting form shown in FIG. 1 , when the movable contact member 165 is snap-fitted with the holding member 166, the movable contact member 165 is moved in the X-axis direction (X1 direction in the X1-X2 direction) indicated by the arrow A to insert the insertion portion 165E into the slit portion 166E, and the received portion 165D is received in the receiving portion 166D and snap-fitted. In the snap-fitting, the received portion 165D is received in the receiving portion 166D by moving in the Z-axis direction (Z1 direction in the Z1-Z2 direction) indicated by the arrow B. That is, when the movable contact member 165 is moved in the X1-X2 direction X1 direction indicated by the arrow A, the portion of the holding member 166 that protrudes to the X2 side of the X1-X2 direction from the receiving portion 166D contacts the front end of the received portion 165D. This contact causes at least one of the protruding portion of the holding member 166 to be elastically deformed and tilted toward the Z1 side in the Z1-Z2 direction, and a portion of the movable contact member 165 to be elastically deformed, causing the front end of the received portion 165D to move toward the Z2 side in the Z1-Z2 direction. When the movable contact member 165 moves toward the X1 direction X1 in this state, the received portion 165D moves toward the inside of the receiving portion 166D, and the elastic deformation is restored, thereby suppressing the displacement of the received portion 165D toward the X2 side in the X1-X2 direction.

[0112] In this way, Fig. 10A In the snap-fit ​​form shown, the movement direction of the received portion 165D when the received portion 165D is snap-fitted to the receiving portion 166D is the Z-axis direction, and therefore, the snap-fit ​​restricts the movement of the movable contact member 165 in the X-axis direction. In addition, the movement direction of the insertion portion 165E when the insertion portion 165E is inserted into the slit portion 166E is the X-axis direction, and therefore, in the state where the insertion portion 165E is inserted into the slit portion 166E, the movement of the movable contact member 165 in the Z-axis direction is restricted.

In the snap-fitting, the received portions 165D are received in the receiving portions 166D by moving in the X-axis direction indicated by the arrow B. In the snap-fitting state, the movable contact member 165 is restricted in the X-axis direction by the plurality of receiving portions 166D, and is also restricted in the Z-axis direction.

In the snap-fitting, the received portion 165D is received in the receiving portion 166D by moving in the X-axis direction (X1-X2 direction X2 direction) indicated by the arrow B.

[0120] When the received portion 165D is snap-fitted to the receiving portion 166D, the movement direction of the received portion 165D is the X-axis direction, and therefore, the snap-fitting restricts the movement of the movable contact member 165 in the Z-axis direction. In addition, when the insertion portion 165E is inserted into the slit portion 166E, the movement direction of the insertion portion 165E is the Z-axis direction, and therefore, in the state where the insertion portion 165E is inserted into the slit portion 166E, the movement of the movable contact member 165 in the X-axis direction is restricted.

[0121] exist Fig. 12B In the snap-fit ​​configuration shown, except Fig. 12A In addition to the embodiment shown in the figure, a force applying structure 190 is provided, which applies force to make the received portion 165D and the receiving portion 166D elastically contact each other.

[0122] In the snap-fit ​​state, the force-applying structure 190 applies force to the received portion 165D in the Z-axis direction (Z1-Z2 direction Z2 direction) indicated by the arrow C, so that the received portion 165D and the receiving portion 166D are in elastic contact. Fig. 12A The same as the form shown, the movement of the movable contact member 165 in the Z-axis direction and the X-axis direction is restricted, and the elastic contact between the accommodated portion 165D and the accommodating portion 166D based on the force-applying structure 190 can improve the holding stability of the movable contact member 165 by the retaining member 166.

In the snap-fitting, the two received portions 165D are received in the receiving portion 166D by moving in the Z-axis direction (Z1-Z2 direction, Z2 direction) indicated by the arrow B.

[0124] When the two received portions 165D are snap-fitted to the receiving portion 166D, the movement direction of the received portion 165D is the Z-axis direction, so the snap-fitting restricts the movement of the movable contact member 165 in the X-axis direction.

[0132] (Operation of the switch device)

[0133] Figures 15 to 26 This is a schematic diagram for explaining the operation of the switch device.

[0134] <First State>

[0135] Fig.15 The state (first state) in which the slider 130 is not pressed down is shown. In the first state, the pressing surface 130A provided at the lower end of the slider 130 abuts against the cam ridge 162C provided at the front end of the cam 162. In addition, in the first state, the movable contact member 165 held by the second actuator 164 is in a horizontal state, the pair of contact pieces 165A are in contact with the first contact 171, and the common contact portion 165B is in contact with the common contact member 173. That is, the switch device 100 is in the first connection state.

[0136] <Second State>

[0137] When from Fig.15 When the slider 130 is pressed down in the first state shown in FIG. Fig.16 As shown, the pressing surface 130A of the slider 130 presses downwardly the cam ridge 162C of the cam 162. As a result, the cam 162 starts to rotate downwardly around the rotation shaft 162B supported by the shaft support 164A of the second actuator 164 as the rotation center.

[0138] Then, if Fig.16 As shown in FIG. 1 , after the slider 130 starts to slide downward, when the slider 130 slides slightly downward, each pressing portion 130B (refer to FIG. 1 ) on both sides of the slider 130 in the left-right direction (Y-axis direction) is pressed. Figure 4 ) abuts against the upper abutment surfaces 161B on both sides of the first actuator 161 in the left-right direction (Y-axis direction). As a result, the slider 130 starts to press the first actuator 161 downward in addition to the cam 162. The first actuator 161 is pressed downward by the pressing portion 130B of the slider 130, thereby starting to move with the first shaft portion 112C (see Figure 4 ) is the center of rotation and rotates downward.

[0139] <Third State>

[0140] Furthermore, when Fig.16 When the slider 130 slides slightly downward from the second state shown in FIG. Fig.17As shown, the lower inclined surface 161C of the first actuator 161 contacts the cam nose 162C of the cam 162. Thereafter, the cam nose 162C of the cam 162 separates from the pressing surface 130A of the slider 130 and is pressed downward by the lower inclined surface 161C of the first actuator 161.

[0141] <Fourth State>

[0142] Then, if Fig.18 As shown in FIG. 1 , when the first actuator 161 rotates downward to a predetermined angle, the rotation of the first actuator 161 is restricted. At this time, due to the force from the torsion spring 163, the force of the cam ridge 162C of the cam 162 to slide on the lower inclined surface 161C of the first actuator 161 exceeds the friction resistance between the cam ridge 162C and the lower inclined surface 161C, and thus the cam ridge 162C instantly slides on the lower inclined surface 161C toward the top 161D of the lower inclined surface 161C, enters the top 161D and stops. At this time, since the top 161D is a gently curved surface, the abutment sound of the cam ridge 162C and the top 161D is suppressed.

[0143] <5th State>

[0144] Therefore, if Fig.19 As shown, the rotating shaft portion 162B of the cam 162 instantly pulls up the shaft support portion 164A of the second actuator 164. At this time, the second actuator 164 rotates upward with the contact point between the common contact portion 165B of the movable contact member 165 held by the second actuator 164 and the common contact member 173 (i.e., the bent portion of the common contact member 173) as a fulcrum. As a result, the contact position of the pair of contact pieces 165A of the movable contact member 165 held by the second actuator 164 is instantly switched from the first contact 171 to the second contact 172. As a result, the second contact 172 and the common contact member 173 are connected to each other via the movable contact member 165, that is, the switch device 100 is switched to the second connection state. As a result, the switch device 100 can perform a switching operation based on a snap action.

[0145] <Sixth State>

[0146] Furthermore, if Fig. 20 As shown in FIG. 1 , when the slider 130 is further pressed downward due to the overstroke caused by the slider 130 being further pressed downward after the switching operation, the first actuator 161, while the rotation angle is fixed, presses down the cam ridge 162C of the cam 162 and slides downward together with the slider 130. At this time, the sliding of the first actuator 161 is guided by the guide rib 110C provided on the inner wall surface on the positive side of the X axis of the housing 110. In addition, at this time, the first actuator 161 gradually moves downward away from the first shaft portion 112C of the cover 112, which is the rotation center.

[0147] <Seventh State>

[0148] Then, if Fig.21 As shown, when the slider 130 is pressed down until the lower end 130E of the slider 130 (refer to Figure 4 ) contacts the bottom 110B of the housing 110, the downward sliding of the slider 130 and the first actuator 161 stops. Fig.21 This shows a state where the slider 130 is pushed down to the maximum extent due to the overstroke of the slider 130 .

[0149] Afterwards, when the pressing operation of the slider 130 is released, the slider 130 is pushed upward by the cam 162 and the first actuator 161 due to the force from the torsion spring 163, and returns to the Fig.15 Initial position shown.

[0150] <8th State>

[0151] Specifically, from Fig.21 From the 7th state shown, Fig. 22 As shown in FIG. 1 , the cam portion 162C of the cam 162 pushes the first actuator 161 upward by the force from the torsion spring 163. As a result, the first actuator 161 pushes the slider 130 upward while sliding with the rotation angle fixed. At this time, the sliding of the first actuator 161 is guided by the guide rib 110C provided on the inner wall surface of the housing 110 on the positive side of the X axis. Then, as shown in FIG. Fig. 22 As shown in FIG. 1 , when the first actuator 161 comes into contact with the first shaft portion 112C of the cover 112 , the upward sliding of the first actuator 161 stops.

[0152] <9th State>

[0153] Afterwards, if Fig.23 As shown, when the first actuator 161 is pushed upward by the cam portion 162C of the cam 162, it rotates upward while being supported by the first shaft portion 112C of the cover 112, thereby pushing up the slider 130. Fig.241 shows that the first actuator 161 is rotatably supported by the first shaft portion 112C of the cover 112. Then, due to the force from the torsion spring 163, the force of the cam portion 162C of the cam 162 to slide up on the lower inclined surface 161C of the first actuator 161 exceeds the friction resistance between the cam portion 162C and the lower inclined surface 161C, and thus the cam portion 162C instantly slides up on the lower inclined surface 161C toward the front end of the first actuator 161. Along with this, the pull-up of the shaft support portion 164A of the second actuator 164 by the rotation shaft portion 162B of the cam 162 is released, that is, the second actuator 164 instantly rotates downward with the contact point between the common contact portion 165B of the movable contact member 165 and the common contact member 173 as the rotation center.

[0154] <10th State>

[0155] Then, if Fig.25 As shown in FIG. 1 , when the second actuator 164 is momentarily rotated downward, the contact position of the pair of contact pieces 165A of the movable contact member 165 held by the second actuator 164 is momentarily switched from the second contact 172 to the first contact 171. As a result, the first contact 171 and the common contact member 173 are connected to each other via the movable contact member 165, that is, the switch device 100 is momentarily switched to the first connection state. In this way, since the switch device 100 has a snap-action mechanism, it is possible to perform a momentary switching operation between the first connection state and the second connection state. In addition, as shown in FIG. Fig.25 As shown, when the contact position of the cam hill portion 162C of the cam 162 is switched from the lower inclined surface 161C of the first actuator 161 to the pressing surface 130A of the slider 130, the upward rotation of the first actuator 161 ends, and the cam hill portion 162C of the cam 162 applies an upward force to the pressing surface 130A of the slider 130, directly causing the slider 130 to slide upward.

[0156] <11th State>

[0157] Then, if Fig.26 As shown, when the slider 130 contacts the lower surface of the cover 112, the upward sliding of the slider 130 stops. Fig. 22 This shows a state where the slider 130 is pushed up to the maximum (initial state).

[0158] As described above, according to the present embodiment, it is possible to provide the switch device 100 that can easily and reliably perform relative position alignment between the switching contact member 170 and the movable contact member 165 .

[0159] In addition, the present embodiment is described above, but the present invention is not limited to these examples.
