本発明は、操作つまみ等によって揺動操作されるスイッチ装置に係り、特に、導体板を揺動させて固定接点部材に接離させることによりオン・オフの切り替えが行われ、例えば車載用パワーウィンドウ装置の駆動スイッチ等に用いて好適なスイッチ装置に関する。 The present invention relates to a switch device which is swung by the operation knob and the like, in particular, is switched on and off is performed by contacting and separating the fixed contact member is swung in the conductive plates, for example, automotive power window of the preferred switching device using the drive switch of the apparatus.
図９はこの種のスイッチ装置の従来例を示す断面図であり、同図に示すように、底壁１ａを有するケース１にはインサート成形加工によって第１と第２および第３の固定接点部材２ａ，２ｂ，２ｃが固定されており、各固定接点部材２ａ〜２ｃからはケース１の下方へ突出する３本の端子８が延設されている。 Figure 9 is a sectional view showing a conventional example of this type of switch device, as shown in the figure, the first and second and third fixed contact member by insert molding in the case 1 having a bottom wall 1a 2a, 2b, 2c are fixed, three terminals 8 from the fixed contact member 2a~2c projecting downward in the case 1 are extended. 各固定接点部材２ａ〜２ｃはケース１の底壁１ａ上に露出しており、導体板３が中央の固定接点部材２ａを支点として揺動可能に配置されている。 Each fixed contact member 2a~2c is exposed on the bottom wall 1a of the case 1, the conductive plate 3 is pivotably arranged a central fixed contact member 2a as a fulcrum. この導体板３は谷部３ａの両側に一対の立上り部３ｂ，３ｃを有する側面視略Ｍ字形の金属板であり、長手方向一端側が固定接点部材２ｂと接離可能で、長手方向他端側が固定接点部材２ｃと接離可能である。 A pair of rising portions 3b on both sides of the conductive plate 3 valleys 3a, a metal plate side view M-shaped having 3c, one longitudinal end side of the movable toward and away from the fixed contact member 2b, the other end side in the longitudinal direction the fixed contact member 2c and is separably. 導体板３上には駆動体４の作動部４ａが配置されている。 On the conductor plate 3 is actuated portion 4a of the driving body 4 is arranged. 駆動体４はコイルばね５によって底壁１ａ側へ常時弾性付勢されているので、作動部４ａは導体板３に弾接している。 The driving body 4 is always urged resiliently toward the bottom wall 1a side by the coil spring 5, the actuating portion 4a is in contact with the conductive plate 3 elastically. これらの駆動体４およびコイルばね５は、回動レバー６の収納部６ａ内に組み込まれている。 The driving member 4 and the coil spring 5 is incorporated in the holding section 6a of the rotating lever 6. この回動レバー６はケース１を覆うように取り付けられた蓋体７に回動自在に支持されており、適宜手段によって図示せぬ操作つまみが回動レバー６に取り付けられる。 The turning lever 6 is rotatably supported in the cover 7 mounted to cover the case 1, the operation knob (not shown) by suitable means is attached to the turning lever 6. この操作つまみは操作者に揺動操作される部材であり、操作つまみの揺動に伴って回動レバー６が回動するので、駆動体４の作動部４ａが導体板３上を摺動する。 The operating knob is a member is swung to the operator, the turning lever 6 in accordance with the swing of the operation knob so rotated, the operating portion 4a of the driving member 4 slides on the conductive plate 3 .
図９は回動レバー６が回転していない非操作時の状態（待機状態）を示しており、固定接点部材２ａ，２ｃが導体板３を介して導通され、固定接点部材２ａ，２ｂ間はスイッチオフ状態に保たれている。 Figure 9 shows the non-operation state in which the turning lever 6 is not rotated (standby state), the fixed contact member 2a, 2c is conducted through a conductive plate 3, the fixed contact members 2a, 2b between the It is kept to the switch off state. この状態で操作つまみを押し込んで回動レバー６を図示時計回りに回転させると、コイルばね５を圧縮させながら作動部４ａが立上り部３ｂ上を摺動するので、作動部４ａが固定接点部材２ａ上を通過した時点で導体板３が図示反時計回りに回転駆動される。 Rotation of the turning lever 6 in the drawing clockwise pushes the operating knob in this state, since the operating portion 4a while compressing the coil spring 5 slides on the rising portion 3b, operating portion 4a fixed contact member 2a the conductive plate 3 when passing over is rotated in the counterclockwise. その結果、導体板３は固定接点部材２ｃから離れて固定接点部材２ｂに当接するので、固定接点部材２ａ，２ｂが導体板３を介して導通されてスイッチオン状態に切り替わる。 As a result, since the conductive plate 3 abuts the fixed contact member 2b away from the fixed contact member 2c, the fixed contact members 2a, 2b is conducted through a conductive plate 3 is switched to the switched-on state. そして、操作つまみを押し込んでいる操作力が除去されると、コイルばね５の復元力により作動部４ａが立上り部３ｂ上を逆向きに摺動するので、作動部４ａが固定接点部材２ａ上を通過した時点で導体板３が逆向きに回転駆動されて図９の待機状態に戻り、よって固定接点部材２ａ，２ｂ間は自動的にスイッチオフ状態に復帰する。 When the operating force that pushes the operating knob is removed, since the operation portion 4a by the restoring force of the coil spring 5 slides on the rising portion 3b in the reverse direction, actuating portion 4a on the fixed contact member 2a the conductor plate 3 at the time of the passage being rotated in the opposite direction to return to the resting state of FIG. 9, thus fixing the contact member 2a, the inter 2b automatically returns to the switched-off state.
また、図９の状態で操作つまみを介して回動レバー６を図示反時計回りに回転させた場合には、作動部４ａは立上り部３ｃ上を摺動するが、導体板３は予め固定接点部材２ｃに押し付けられているので回転駆動されず、それゆえ固定接点部材２ａ，２ｂ間はスイッチオフ状態のままである。 Further, when rotating the rotating lever 6 to the counterclockwise via the operation knob in a state of FIG. 9, the actuating portion 4a is slides on the rising portion 3c, the conductive plate 3 is previously fixed contact not rotated because it is pressed against the member 2c, and therefore the fixed contact member 2a, and 2b remains switched-off state.
このようなスイッチ装置は、車載用パワーウィンドウ装置の駆動スイッチとして広く採用されている。 Such switching devices are widely used as a driving switch of a vehicle-mounted power window device. その場合、操作つまみを押し込んでいる間だけウィンドウの開動作や閉動作を行わせる駆動信号を出力させることができるので、ウィンドウの開度が任意に設定可能なマニュアル操作が行える。 In that case, it is possible to output a driving signal for causing the opening operation and closing operation of the window only while pushing the operation knob, it performed arbitrarily settable manually operated window opening.
ところで、前述した従来のスイッチ装置では、駆動体４をコイルばね５と組み合わせて導体板３上に保持しておくために、大きめの収納部６ａを有する回動レバー６を蓋体７によって回動自在に支持しているが、この回動レバー６には相応の高さ寸法が必要なので装置全体の薄型化が図りにくいという問題があった。 However, turning the conventional switching device described above, in order to hold the driving body 4 on the conductor plate 3 in combination with a coil spring 5, the turning lever 6 having a larger housing portion 6a by lid 7 While being freely supported, there is a problem that it is difficult achieving reduction of the thickness of the entire device because the required height corresponding to the turning lever 6. 加えて、回動レバー６と蓋体７との間には回転動作を保証するクリアランスＣが必要なので、ケース１内の接点部分に塵埃等の異物が侵入しやすく、導通の信頼性が損なわれる危険性があった。 In addition, since the clearance C is required, foreign matter easily enters the dust on the contact portion of the case 1, the reliability of conduction is impaired to ensure rotational movement between the turning lever 6 and the lid body 7 there was a danger.
また、車載用パワーウィンドウ装置の駆動スイッチにおいては、ケース１の底壁１ａ上に固定接点部材２ａ〜２ｃ群を二列配設し、それぞれの固定接点部材２ａ〜２ｃ群ごとに導体板３や作動部４ａ等を配置させることにより二組のスイッチ素子が並設され、操作つまみを一方向へ押し込むと一方のスイッチ素子から開動作を行わせる駆動信号が出力され、操作つまみを他方向へ押し込むと他方のスイッチ素子から閉動作を行わせる駆動信号が出力されるようになっている。 Further, in the drive switch of the in-vehicle power window device, and two rows arranged fixed contact member 2a~2c group on the bottom wall 1a of the case 1, the conductive plate 3 Ya in each of the fixed contact member 2a~2c group two pairs of switching elements arranged in parallel by arranging the operating portion 4a, etc., the drive signal for pushing the operation knob in one direction from one switching element to perform the opening operation is outputted, pushing the operating knob in the other direction so that the drive signal for causing the closing operation is output from the other switch elements and. このような双極・双投型のスイッチ装置の場合、図９に示す従来構造では、駆動体４や複数のコイルばね５が脱落しないように注意しながら回動レバー６をケース１および蓋体７に組み付けていかねばならないため、組立作業性が極めて悪いという問題があった。 For such bipolar-double-throw switch device, conventionally in the structure, the drive member 4 and a plurality of coil springs 5 ​​Case 1 the turning lever 6 being careful not to fall off and the cover 7 shown in FIG. 9 because that must Ika assembled, the assembling workability is there is extremely poor.
また、車載用パワーウィンドウ装置の駆動スイッチにおいては、ウィンドウをワンタッチで全開させたり全閉できる操作機能も要求されるが、このような操作機能を図９に示す従来のスイッチ装置に付加する場合、通常、ケース１の近傍にプッシュスイッチを併設し、操作つまみを介して回動レバー６を大きく回転させると専用の駆動部材が該プッシュスイッチを押圧操作して全開動作あるいは全閉動作を行わせる駆動信号が出力されるようになっている。 Also, if the drive switch of the vehicle power window system is the window fully closed can be manipulated function or is fully opened by one touch is also required, adding such operation function to the conventional switching device shown in FIG. 9, Usually, it features a push switch in the vicinity of the casing 1, to perform the full-open operation or total closing dedicated drive member by pressing the push switch and rotate a large turning lever 6 via the operation knob drive signals are outputted. しかしながら、プッシュスイッチ用の駆動部材を駆動体４との動作タイミングに配慮しつつケース１の外部に付設すると、装置全体がかなり大型なものになってしまい、構造も複雑化するという問題があった。 However, when attached to the outside of the case 1 while considering the driving member for the push switch operation timing of the driving body 4, cause the entire device becomes quite large ones, there is a problem that the structure is also complicated .
本発明は、このような従来技術の実情に鑑みてなされたもので、その目的は、薄型化や構造の簡素化が促進できると共に組立性が良好で信頼性も高いスイッチ装置を提供することにある。 The present invention has such has been made in view of the circumstances of prior art, and its object is to assembly of providing even higher switching device excellent reliability is possible promoted simplification of thickness and structure is there.
上述した目的を達成するため、本発明のスイッチ装置では、底壁および上部開口を有するケースと、このケースに組み付けられた二組のスイッチ素子と、これら二組のスイッチ素子に復帰力を付与する共通の板ばね部材と、この板ばね部材を加圧した状態で前記上部開口を蓋閉するカバー部材とを備え、前記スイッチ素子が、前記ケースに固定されて前記底壁上に露出する固定接点部材と、前記底壁上に揺動可能に配置されて前記固定接点部材に接離可能な導体板と、昇降動作が許容された状態で前記導体板上に配置されて軸部を中心に回動可能な駆動体とを含むと共に、この駆動体に、前記ケースの外方へ突出する被押圧部と、この被押圧部が押し込まれることによって前記導体板の傾斜面上を摺動する摺動作動部とを設け、前記板ばね部 To achieve the above object, in the switch device of the present invention, imparts a case having a bottom wall and an upper opening, and two pairs of switching elements that are assembled to the case, a return force to the two sets of switching elements a common leaf spring member, and a leaf spring member pressurizes the lid closes the cover member to the upper opening while the fixed contact, wherein the switching element is exposed on the bottom wall is fixed to the casing member and the bottom wall on the separable therefrom conductor plate to the fixed contact member is swingably disposed, it is arranged on the conductor board in a state in which the lifting operation is permissible times about the shaft together and a rotatably driving member, the driving member, and a pressed portion which projects outwardly of the casing, sliding operation of sliding on the inclined surface of the conductor plate by the pressed portion is pressed and a dynamic portion is provided, the plate spring portion に、前記カバー部材に押し撓められる圧縮部と、この圧縮部に連続して形成された一対の押圧片とを設け、この押圧片によって前記駆動体の前記軸部を前記底壁へ向けて弾性付勢するように構成した。 In a compression unit flexed pushed to the cover member, and a pair of pressing pieces formed continuously in the compression section provided, toward the shaft portion of the drive member to the bottom wall by the pressing piece It was configured to elastically urged.
このように構成されたスイッチ装置では、板ばね部材の押圧片が駆動体の軸部をケースの底壁へ向けて弾性付勢しているので、ケース外へ突出している駆動体の被押圧部に操作つまみ等を介して操作力を付与することにより、駆動体の回転に伴いその摺動作動部を導体板の傾斜面上で摺動させて、該導体板を回転駆動することができる。 In the thus constructed switch device, since the pressing piece of the leaf spring member is elastically biased toward the shaft portion of the drive member to the case bottom wall, the pressed portion of the driving member which projects to the outside of the case by applying the operating force through the operation knob or the like, the sliding action moving unit with the rotation of the drive member is slid on the inclined surface of the conductive plate, it is possible to rotate the conductor plate. したがって、導体板を固定接点部材に接離させるための他の駆動部材が不要となり、しかも、板ばね部材は駆動体の軸部上の狭いスペースに配置させることができるので、装置全体を容易に薄型化することができる。 Thus, other drive member for contacting and separating the conductive plate to the fixed contact member is not required, moreover, since the plate spring member can be disposed in a narrow space on the shaft portion of the drive member, the entire apparatus easily it can be made thinner. また、操作つまみを大きく押し込んだときにケースの近傍に設置したプッシュスイッチが押圧操作できるように多機能化した場合、ケースの外方へ突出する駆動体の被押圧部によって該プッシュスイッチを作動させることができるので、該プッシュスイッチ用の駆動部材を別途付設する必要がなく、小型薄型化や構造の簡素化に有利である。 The push switch installed in the vicinity of the case may have multiple functions so that it can be pressed to actuate the said push switch by the pressed portion of the driving member which projects outwardly of the case when pushed large operating knob it is possible, it is not necessary to additionally provided a drive member for the push switch, it is advantageous to simplification of a small thickness and structure. さらに、ケースの底壁上に二組のスイッチ素子の各導体板と駆動体を組み込んだ後、その上から板ばね部材とカバー部材の順に組み込むことにより、共通の板ばね部材で二組のスイッチ素子に復帰力を付与することができるので、組立の自動化を図ることができると共に、ケースの上部開口をカバー部材が蓋閉するので、該ケース内に塵埃等の異物が侵入するのを防止して長期間に亘り導通の信頼性を維持できる。 Furthermore, after incorporating the respective conductor plates and the driving of the two pairs of switching elements on the bottom wall of the case, by incorporating thereon in the order of the leaf spring member and the cover member, the two sets by a common leaf spring member switch it is possible to impart a return force to the element, it is possible to automate the assembly, since the upper opening of the cover member is a lid closes the case, foreign matter such as dust is prevented from entering the said casing the reliability of conduction can be maintained over a long period of time Te.
上記の構成において、板ばね部材の前記圧縮部が、前記各押圧片の長手方向一端側から延出する部分を鋭角に折り返して該延出部分どうしを橋絡してなる第１の折曲片と、前記各押圧片の長手方向他端側から延出する部分を鋭角に折り返して該延出部分どうしを橋絡してなる第２の折曲片とを有していれば、板ばね部材をケース内の最上部に配置させた状態でカバー部材を組み付けることにより、第１および第２の折曲片がカバー部材に押し撓められ、各押圧片に向けて弾性付勢されるため、各押圧片にばね圧が生起される。 In the above configuration, the compression of the leaf spring member, the longitudinal direction end portions extending from the side folded back at an acute angle to bridge the the extending portions to each other formed by the first bent piece of the pressing piece When, as long as it has the said respective pressing pieces other longitudinal end side second bent piece formed by bridging portions each other out said extension is folded back portions extending at an acute angle from the leaf spring member since the by assembling the cover member in the state of being placed on top of the case, the first and second bent piece flexed pushing the cover member is resiliently biased toward each pressing piece, spring pressure is caused in the pressing pieces. それゆえ、二組のスイッチ素子に復帰力を付与する板ばね部材を薄型で単純な形状となすことができ、部品コストの低減や薄型化の促進に有利となる。 Therefore, it is possible to make a simple shape leaf spring member for applying a return force to the two pairs of switching elements in thin, which is advantageous in promoting reduction or thinning of the part cost.
また、上記の構成において、ケースの底壁に対して立設された側壁が前記押圧片を長手方向に位置規制すると共に、駆動体の前記軸部に前記押圧片を幅方向に位置規制するガイド壁を設けておけば、組立作業時に板ばね部材を位置決め状態でケース内の最上部に配置させることができ、脱落も防止されるので、自動組立が容易となって組立コストが大幅に低減できる。 Further, in the above-described structure, erected side walls to the bottom wall of the case while the position regulating the pressing piece in the longitudinal direction, controlling the position of the pressing piece in the width direction of the shaft portion of the driver guide if provided wall, it is possible to arrange the leaf spring member during assembly work at the top of the case with the positioning condition, the falling is prevented, the assembly cost can be greatly reduced becomes easier automatic assembly .
また、上記の構成において、二組のスイッチ素子のそれぞれの固定接点部材と導体板および駆動体をいずれも平面視点対称位置に配置しておけば、装置全体を小型化しやすくなるので好ましい。 Further, in the above configuration, because if placed in any plane viewpoint symmetrical positions respective fixed contact member and the conductor plate and the driving of the two pairs of switching elements, it tends to reduce the overall size of the apparatus preferred.

板ばね部材１９は、１枚板の弾性金属板を図１に示すような形状にプレス加工してなるもので、互いに平行に延びる一対の押圧片１９ａ，１９ｂが側面視略ハ字形の圧縮部１９ｃの下端を連結した形状になっている。 The leaf spring member 19 is made of by pressing a resilient metal sheet of a single plate shape as shown in FIG. 1, a pair of pressing pieces 19a extending parallel to one another, 19b are compressed portion of the side view upward toward the inner edge 26b thereof shaped It has a shape formed by connecting the lower end of 19c. ここで、一対の押圧片１９ａ，１９ｂは、各駆動体１７，１８の軸部１７ａ，１８ａを底壁１０ａへ向けて常時弾性付勢するための部位である。 Here, a pair of pressing pieces 19a, 19b is a portion for shank 17a, always biased elastically toward the 18a to the bottom wall 10a of each driver 17, 18. また、圧縮部１９ｃは、カバー部材２０により圧縮されて各押圧片１９ａ，１９ｂにばね圧を発生させるための部位である。 The compression unit 19c, each pressing piece 19a is compressed by the cover member 20 is a part for generating a spring force to 19b. この圧縮部１９ｃは、各押圧片１９ａ，１９ｂの長手方向一端側から延出する部分を鋭角に折り返して該延出部分どうしを橋絡部１９ｅにて橋絡してなる略Ｈ字形の第１の折曲片１９ｄと、各押圧片１９ａ，１９ｂの長手方向他端側から延出する部分を鋭角に折り返して該延出部分どうしを橋絡部１９ｇにて橋絡してなる略Ｈ字形の第２の折曲片１９ｆとからなる。 The compression unit 19c is first generally H-shaped respective pressing pieces 19a, 19b at one longitudinal end a portion extending from the side folded back at an acute angle the extending portions to each other the formed by bridging at bridge 19e of the bent piece 19d, the pressing pieces 19a, 19b longitudinal end portions extending from the side folded back at an acute angle the extending portions to each other substantially H-shaped formed by bridging at bridge 19g of and a second bent piece 19f. 図７，８に示すように、板ばね部材１９は組立時にケース１０内の最上部に組み込まれて、一方の押圧片１９ａが駆動体１７の軸部１７ａ上に配置され、他方の押圧片１９ｂが駆動体１８の軸部１８ａ上に配置される。 As shown in FIGS. 7 and 8, the leaf spring member 19 is built into the top of the case 10 during assembly, one of the pressing piece 19a is disposed on the shaft portion 17a of the driver 17, the other pressing piece 19b There are disposed on the shaft portion 18a of the driver 18. その際、各押圧片１９ａ，１９ｂをそれぞれガイド壁１７ｅ，１７ｅ間とガイド壁１８ｅ，１８ｅ間に挿入することにより幅方向の位置決めが行え、また、板ばね部材１９の長手寸法をケース１０の相対向する側壁１０ｂ，１０ｂの間隔と略同等に設定しておくことにより、各押圧片１９ａ，１９ｂの長手方向の位置決めが行えるようになっている。 At that time, the pressing pieces 19a, 19b respectively guide walls 17e, 17e between the guide wall 18e, can be positioned in the width direction by inserting between 18e, also relative to the longitudinal dimension casing 10 of the leaf spring member 19 sidewall 10b for countercurrent, by setting substantially equal to the spacing 10b, the pressing pieces 19a, are able to perform a longitudinal positioning of 19b. したがって、板ばね部材１９はケース１０内の所定位置に簡単かつ確実に組み込むことができる。 Accordingly, the leaf spring member 19 can be incorporated easily and reliably at a predetermined position in the casing 10.
カバー部材２０には下端部の四隅に取付片２０ａが形成されており、これらの取付片２０ａを折り曲げてケース１０の四隅に係止させることによって、カバー部材２０は上部開口１０ｅを蓋閉した状態でケース１０に取着される。 State in the cover member 20 are attached piece 20a is formed at four corners of the lower end, by engaged with the four corners of the case 10 by bending these mounting pieces 20a, the cover member 20 which closes the lid an upper opening 10e in is attached to the case 10. こうしてカバー部材２０をケース１０に取り付けると、予めケース１０内に組み込まれていた板ばね部材１９は図８の状態から図３の状態へと弾性変形する。 Thus when attaching the cover member 20 to the case 10, advance the leaf spring member 19 built in the case 10 and elastically deformed to the state of FIG. 3 from the state of FIG. つまり、板ばね部材１９をケース１０内の最上部に配置させた状態でカバー部材２０を組み付けることにより、第１および第２の折曲片１９ｄ，１９ｆがカバー部材２０に押し撓められ、各押圧片１９ａ，１９ｂに向けて弾性付勢されるため、各押圧片１９ａ，１９ｂにばね圧が生起される。 In other words, by assembling the cover member 20 a leaf spring member 19 in a state of being placed on top of the case 10, the first and second bent piece 19d, 19f is flexed push the cover member 20, each since the pressing piece 19a, is elastically biased toward 19b, the pressing pieces 19a, the spring pressure is caused to 19b. これにより、一方の押圧片１９ａが駆動体１７の軸部１７ａを底壁１０ａへ向けて弾性付勢し、その付勢力によって駆動体１７の摺動作動部１７ｄが導体板１５に弾接するので、軸部１７ａを中心に駆動体１７を回転させると摺動作動部１７ｄが導体板１５上を摺動し、この導体板１５を回転駆動することができる。 Thus, one of the pressing piece 19a is elastically biased toward the shaft portion 17a of the driver 17 to the bottom wall 10a, so sliding action motion portion 17d of the driver 17 by the biasing force against the conductive plate 15 elastically, shaft portion 17a to rotate the drive member 17 in the center sliding action motion portion 17d slides the conductive plate 15 on the can for rotating the conductive plate 15. 同様に、他方の押圧片１９ｂが駆動体１８の軸部１８ａを底壁１０ａへ向けて弾性付勢し、その付勢力によって駆動体１８の摺動作動部１８ｄが導体板１６に弾接するので、軸部１８ａを中心に駆動体１８を回転させると摺動作動部１８ｄが導体板１６上を摺動し、この導体板１６を回転駆動することができる。 Similarly, the shaft portion 18a of the other pressing piece 19b is driven body 18 and elastically biased toward the bottom wall 10a, so sliding action motion portion 18d of the driver 18 by the biasing force against the conductive plate 16 elastically, shaft portion 18a to rotate the drive member 18 in the center sliding action motion portion 18d slides on the conductor plate 16, it is possible for rotating the conductive plate 16.
上述したスイッチ装置は、固定接点部材１１ａ〜１１ｃや導体板１５、駆動体１７、押圧片１９ａ等を接点収納空間Ｓ１内に配置させてなる第１のスイッチ素子と、固定接点部材１２ａ〜１２ｃや導体板１６、駆動体１８、押圧片１９ｂ等を接点収納空間Ｓ２内に配置させてなる第２のスイッチ素子とが、ケース１０内に並設された構成になっている。 Above switch device, the fixed contact member 11a~11c and the conductive plate 15, the drive member 17, a first switch element of the pressing piece 19a or the like becomes so disposed contact housing space S1, Ya fixed contact member 12a~12c conductive plate 16, the drive member 18, a second switch element formed by the pressing piece 19b or the like is arranged in the contact housing space S2 is has become juxtaposed configuration in the case 10. ただし、これら第１および第２のスイッチ素子に復帰力を付与するばね部材は共通の板ばね部材１９である。 However, a spring member for applying a restoring force to the first and second switching elements is a common leaf spring member 19.
また、上述したスイッチ装置は、車載用パワーウィンドウ装置に組み付けられるときに、カバー部材２０の上方に操作つまみ２１（図４参照）が取り付けられるが、その際、操作つまみ２１に設けた一対の押圧突起部２１ｂ，２１ｃをそれぞれ駆動体１７，１８の被押圧部１７ｂ，１８ｂに弾接させてプリテンションをかけた状態（与圧状態）にしておくことにより、操作つまみ２１と駆動体１７，１８との間のガタを回避している。 Further, the above-described switch device, when assembled to vehicle power window device, but above the operating knob 21 of the cover member 20 (see FIG. 4) is attached, whereby the pair of pressing provided in the operation knob 21 projections 21b, the pressed portion 17b of 21c each driver 17, 18, 18b to by elastic contact with by keeping the state (pressurized state) multiplied by the pre-tensioning, the operating knob 21 and the drive member 17, 18 thereby avoiding the backlash between. かかる与圧状態において、駆動体１７，１８の摺動作動部１７ｄ，１８ｄはそれぞれ、導体板１５，１６の立上り部１５ｂ，１６ｂの下端近傍の傾斜面と当接しているが、操作つまみ２１を取り外すと図３に示すように、摺動作動部１７ｄ，１８ｄはそれぞれ導体板１５，１６の初期受け部１５ａ，１６ａと当接し、被押圧部１７ｂ，１８ｂの高さ位置が若干上昇する。 In such pressurized state, sliding action motion portion 17d of the driver 17, 18, respectively 18 d, the rising portion 15b of the conductive plates 15 and 16, is in contact inclined surface near the lower end of 16b and those, the operation knob 21 remove the 3, sliding action moving part 17d, 18 d each initial receiving portion 15a of the conductive plate 15, 16, 16a abuts, the pressed portion 17b, the height position of 18b is slightly increased. なお、図３の状態から与圧状態へ移行するときに発生する駆動体１７，１８の回転量を予め考慮して、駆動体１７，１８の初期位置や導体板１５，１６の形状を定めておくことにより、導体板１５，１６上で摺動作動部１７ｄ，１８ｄを摺動させながら被押圧部１７ｂ，１８ｂを大きく昇降させうる構造が容易に実現できる。 Incidentally, in advance considering the amount of rotation of the drive member 17, 18 that occurs when moving from the state of FIG. 3 to pressurized state, defining the shape of the initial position and the conductor plates 15 and 16 of the driver 17, 18 by placing, sliding action pivot portion 17d on the conductive plate 15, 16, 18 d pressed portion 17b while sliding, 18b greatly elevating the cause can structure can be easily realized.
このように構成されたスイッチ装置の動作について説明すると、操作力が付与されていない待機状態（前記与圧状態）には、駆動体１７の摺動作動部１７ｄが導体板１５の立上り部１５ｂの下端部に弾接しているので、固定接点部材１１ａ，１１ｃが導体板１５を介して導通され、固定接点部材１１ａ，１１ｂ間はスイッチオフ状態に保たれている。 In operation of the thus configured switching device, the standby state where the operation force is not applied (the pressurized state), sliding action motion portion 17d of the driver 17 of the rising portion 15b of the conductive plate 15 since the elastic contact with the lower end, the fixed contact members 11a, 11c is conducted through the conductive plate 15, the fixed contact member 11a, the inter 11b is kept switched-off state. また、駆動体１８の摺動作動部１８ｄは導体板１６の立上り部１６ｂの下端部に弾接しているので、固定接点部材１２ａ，１２ｃが導体板１６を介して導通され、固定接点部材１２ａ，１２ｂ間はスイッチオフ状態に保たれている。 Also, sliding action motion portion 18d of the driver 18 because the elastic contact with the lower end of the rising portion 16b of the conductive plate 16, the fixed contact members 12a, 12c is conducted through the conductive plate 16, the fixed contact member 12a, 12b between is kept switched-off state.
この状態で操作つまみ２１に対し、例えば図４に矢印で示すような操作力を加えると、押圧突起部２１ｂが駆動体１７の被押圧部１７ｂを押し込んでいくのに伴い、腕部１７ｃが図示反時計回りに回転して、摺動作動部１７ｄが導体板１５の立上り部１５ｂ上を斜め上方へ摺動していき、軸部１７ａが押圧片１９ａに抗して若干押し上げられていく。 To the operation knob 21 in this state, for example, the addition of operating force, as shown by the arrows in FIG. 4, as the pressing protrusion 21b is pushed to the pushed portion 17b of the driver 17, the arm portion 17c is shown It rotates counterclockwise, sliding action motion portion 17d is gradually slides on the rising portion 15b of the conductive plate 15 obliquely upward, the shaft portion 17a is gradually pushed up slightly against the pressing piece 19a. そして、摺動作動部１７ｄが固定接点部材１１ａ上を通過した時点で、導体板１５が回転駆動されて、図４の状態となる。 Then, when the sliding operation moving part 17d passes over the fixed contact members 11a, the conductive plate 15 is driven to rotate, the state of FIG. その結果、平坦部１５ｃが固定接点部材１１ｃから離れて可動接点部１５ｄが固定接点部材１１ｂに当接するので、導体板１５を介して固定接点部材１１ａ，１１ｂが導通されたことによるスイッチオンの切り替え信号（ウィンドウの開動作を行わせる駆動信号）が端子１３から出力される。 As a result, the flat portion 15c is movable contact portion 15d away from the fixed contact member 11c is brought into contact with the fixed contact member 11b, switching of the switch-on due to the fixed contact member 11a via the conductive plate 15, 11b is conductive signal (drive signal for causing the opening operation of the window) is outputted from the terminal 13.
また、図４の状態で操作つまみ２１に対する操作力が除去された場合には、押圧片１９ａの復元力が駆動体１７の軸部１７ａに作用し、摺動作動部１７ｄが立上り部１５ｂの傾斜面に沿って斜め下方へ移動するので、摺動作動部１７ｄが固定接点部材１１ａ上を通過した時点で導体板１５が逆向きに回転駆動されると共に、被押圧部１７ｂによって押圧突起部２１ｂが押し上げられていく。 Further, when the operation force to the operation knob 21 is removed in the state of FIG. 4, the restoring force of the pressing piece 19a is applied to the shaft portion 17a of the driver 17, the inclined sliding action motion portion 17d is of the rising portion 15b since moving obliquely downward along the surface, together with the conductor plate 15 is rotated in the opposite direction when the sliding operation moving part 17d passes over the fixed contact member 11a, the pressing projection portion 21b by the pressed portion 17b go pushed up. その結果、導体板１５の可動接点部１５ｄが固定接点部材１１ｂから離れて平坦部１５ｃが固定接点部材１１ｃに当接するので、固定接点部材１１ａ，１１ｂの導通が遮断されたことによるスイッチオフの切り替え信号が端子１３から出力され、操作つまみ２１の傾きが解消された待機状態に復帰する。 As a result, the flat portion 15c movable contact portion 15d of the conductive plate 15 is separated from the fixed contact member 11b is brought into contact with the fixed contact member 11c, the switching of the switch-off due to the fixed contact members 11a, conduction of 11b is interrupted signal is output from the terminal 13, returns to the standby state slope is eliminated in the operation knob 21.
次に、図４の状態で操作つまみ２１をもう一段押し込んだ場合の動作について説明する。 Next, operation will be described when pushed another stage the operating knob 21 in the state of FIG. このとき、摺動作動部１７ｄが導体板１５の立上り部１５ｂ上をさらに摺動していくので、軸部１７ａに作用する押圧片１９ａの付勢力は一層増大するが、押圧突起部２１ｂによって下方へ大きく押し込まれた被押圧部１７ｂが操作部位２３ａを押し込むためプッシュスイッチ２３が作動され、ウィンドウを全開させる駆動信号が出力される。 At this time, since the sliding action motion portion 17d is gradually further slides on the rising portion 15b of the conductive plate 15, the biasing force of the pressing piece 19a acting on the shaft portion 17a is further increased, the lower the pressing protrusion 21b to increase pushed-in pressed portion 17b is a push switch 23 to push the operation portion 23a is operated, a drive signal for fully opening the window is output. また、この状態で操作つまみ２１に対する操作力が除去されると、押圧片１９ａの復元力により摺動作動部１７ｄが立上り部１５ｂの傾斜面に沿って斜め下方へ移動するので、図４の状態を経て待機状態に復帰する。 Further, when the operation force to the operation knob 21 in this state is removed, since sliding action moving part 17d by the restoring force of the pressing piece 19a is moved obliquely downward along the inclined surface of the rising portion 15b, the state of FIG. 4 It returns to the standby state through.
なお、待機状態で押圧突起部２１ｃを押し下げる向きに操作つまみ２１を回転させた場合には、駆動体１８の被押圧部１８ｂが押圧突起部２１ｃに押し込まれて腕部１８ｃが回転し、摺動作動部１８ｄが導体板１６の立上り部１６ｂ上を斜め上方へ摺動するので、軸部１８ａが押圧片１９ｂに抗して押し上げられていき、摺動作動部１８ｄが固定接点部材１２ａ上を通過した時点で導体板１６が回転駆動される。 Incidentally, in the case of rotating the operation knob 21 in the direction to push down the pressing projections 21c in the standby state, the arm portion 18c is rotated pressed portion 18b of the driver 18 is pushed by the pressing projections 21c, sliding action since the dynamic portion 18d slides on the rising portion 16b of the conductive plate 16 obliquely upward, the shaft portion 18a is gradually pushed up against the pressing piece 19b, sliding action motion portion 18d is passed over the fixed contact members 12a conductive plate 16 is rotated at the time of the. したがって、固定接点部材１２ａ，１２ｂが導通されたことによるスイッチオンの切り替え信号（ウィンドウの閉動作を行わせる駆動信号）が端子１４から出力される。 Accordingly, the fixed contact members 12a, a switching signal of a switch-on due to 12b is conductive (the drive signal for causing the closing operation of the window) is outputted from the terminal 14. そして、この状態で操作つまみ２１をもう一段押し込むと、押圧突起部２１ｃが被押圧部１８ｂを介して操作部位２４ａを押し込み、プッシュスイッチ２４を作動させることができるので、ウィンドウを全閉させる駆動信号が出力可能となる。 When pushed another stage the operation knob 21 in this state, pressing projection portion 21c via the pressed portion 18b pushes the operation portion 24a, it is possible to operate the push switch 24, the drive signal for closed all the windows There can be outputted. また、操作力を除去すると押圧片１９ｂの復元力により摺動作動部１８ｄが立上り部１６ｂの傾斜面に沿って斜め下方へ移動するので、導体板１６が逆向きに回転駆動されると共に、被押圧部１８ｂによって押圧突起部２１ｃが押し上げられていき、待機状態に復帰する。 Further, since the sliding operation moving unit 18d Removal of the operating force by the restoring force of the pressing piece 19b is moved obliquely downward along the inclined surface of the rising portion 16b, together with the conductor plate 16 is rotated in the opposite direction, the gradually pushed up the pressing projection portion 21c by the pressing portion 18b, and returns to the standby state.
