上述したように、本発明の押釦スイッチは、収納部を有する筐体と、収納部内に配設された反転ばねと、筐体の側部より突出する押圧部と作動部とを有し収納部内をスライド移動する操作部材とを備え、押圧部のスライド方向への押圧操作に伴い、作動部を介して反転ばねを操作部材のスライド方向と交差する方向へ押圧させ、この押圧による反転ばねの反転動作によってクリック感触の生成とスイッチ信号の切換えとを行なう押釦スイッチであって、操作部材の押圧操作時に、操作部材が反転ばねをスイッチ切換え位置へ反転させるまでスライド移動した後に当接して、それ以降、スライド移動した操作部材への復帰力を付与する復帰ばね部を設けたことから、押釦スイッチの復帰操作を、反転した反転ばねの自らの反転復帰する蓄力による操作部材への付勢力に加えて、復帰ばね部の復帰力とによって操作部材の復帰を行なうので、操作部材の復帰を確実に行うことができる。また、反転ばねのスイッチ切換え位置への反転動作途上では操作部材に復帰ばね部の付勢力は作用しないため、所望のクリック感触を得ることができる。 As described above, the pushbutton switch of the present invention includes a housing having a housing portion, a reversing spring disposed in the housing portion, a pressing portion protruding from a side portion of the housing, and an operating portion. An operation member that slides and moves the reversing spring in a direction that intersects the sliding direction of the operation member via the operating portion in accordance with the pressing operation in the sliding direction of the pressing portion, and the reversing of the reversing spring by this pressing. A pushbutton switch that generates a click feeling and switches a switch signal by operation, and when the operation member is pressed, the operation member slides until it reverses the reversing spring to the switch switching position, and then comes into contact. Since the return spring portion is provided to apply the return force to the slid operation member, the return operation of the push button switch is performed by the stored force of the inverted reverse spring. In addition to the urging force to the operation member, because the return of the operating member by the restoring force of the return spring portion, it is possible to reliably return the operating member. Further, since the urging force of the return spring portion does not act on the operating member during the reversing operation of the reversing spring to the switch switching position, a desired click feeling can be obtained.

また、復帰ばね部を、操作部材あるいは筐体のどちらか一方に形成し、操作部材が反転ばねをスイッチ切換え位置へ反転させるまでスライド移動した際には、操作部材と筐体とが復帰ばね部を介して当接可能なように配置したことから、復帰ばね部を操作部材あるいは筐体のどちらか一方に設けることにより、構成が簡易となり、組立性が向上される。
また、操作部材と筐体との間に、操作部材がスライド方向へ移動する際に互いに当接するストッパー部を設け、操作部材と筐体とが復帰ばね部を介して当接してからストッパー部と当接するまでの間、復帰ばね部により操作部材へ復帰力を付与するようにしたことから、操作部材がストッパー部と当接する位置にスライド移動するまで復帰ばね部が連続して復帰力を付与するので、操作部材のスライド移動後の復帰を確実に行なうことができる。 Further, when the return spring portion is formed on either the operation member or the housing and the operation member slides until the reversing spring is reversed to the switch switching position, the operation member and the housing are returned to the return spring portion. Since the return spring portion is provided on either the operating member or the housing, the configuration is simplified and the assemblability is improved.
Further, a stopper portion that contacts each other when the operation member moves in the sliding direction is provided between the operation member and the housing, and after the operation member and the housing are contacted via the return spring portion, Since the return spring is applied to the operation member by the return spring until the contact, the return spring continuously applies the return force until the operation member slides to a position where it comes into contact with the stopper. Therefore, the return of the operating member after the sliding movement can be performed reliably.

また、筐体は、収納部を有する合成樹脂材製のハウジングと、このハウジングの上面に取付けられた金属板製の蓋体とからなり、復帰ばね部を、蓋体に形成したことから、復帰ばね部を金属板で形成したので、押釦スイッチの長寿命化が図れる。また、組立を簡単に行なうことができる。
また、反転ばねの裏面に接点部を設けて可動接点を形成し、ハウジングの収納部の内底面に固定接点を設け、この固定接点上に反転ばねを反復反転可能に配設し、操作部材の押圧操作時に、作動部を介して反転ばねが反転して接点部が固定接点と接触してスイッチ信号の切換えが行なわれると共に、それ以降、操作部材がスライド移動した際に、復帰ばね部により操作部材へ復帰力を付与するようにしたことから、操作部材がスイッチ信号の切換えが行なわれた後のスライド位置で、復帰ばね部が復帰力を付与するので、操作部材の復帰を確実に行なえ、所望のクリック感触を得ることができる。 Further, the casing is made of a synthetic resin material housing having a storage portion and a metal plate lid attached to the upper surface of the housing, and the return spring portion is formed on the lid. Since the spring portion is formed of a metal plate, the life of the push button switch can be extended. Moreover, assembly can be performed easily.
Further, a contact portion is provided on the back surface of the reversing spring to form a movable contact, a fixed contact is provided on the inner bottom surface of the housing housing portion, and the reversing spring is disposed on the fixed contact so as to be repeatedly reversible. At the time of pressing operation, the reversing spring is reversed via the actuating part, and the contact part comes into contact with the fixed contact to switch the switch signal. Thereafter, when the operating member slides, it is operated by the return spring part. Since the return force is applied to the member, since the return spring portion applies the return force at the slide position after the switch signal is switched, the operation member can be reliably returned. A desired click feeling can be obtained.

また、操作部材に可撓性を有する作動部を形成し、蓋体にはハウジングの収納部内に切り起こされた傾斜片を形成し、操作部材の押圧操作時に、押圧部の押圧に伴って作動部が傾斜片上を摺動して下方へ撓むことで作動部が反転ばねを押圧するようにしたことから、操作部材のスライド操作時に反転ばねを下方へ押圧する作動部を操作部材に一体的に形成できるので、押釦スイッチの薄型化が図れる。
また、操作部材の作動部に傾斜面を形成し、ハウジングの収納部には揺動可能な駆動変換部材を設け、操作部材の押圧操作時に、押圧部の押圧に伴って作動部の傾斜面が駆動変換部材と摺動し、駆動変換部材が下方へ撓むことで反転ばねを押圧するようにしたことから、作動部と当接して揺動可能な駆動変換部材を設けることにより、操作部材のスライド方向と交差する方向に駆動変換部材を移動できるので、確実に反転ばねを下方へ押圧することができる。 In addition, a flexible operating part is formed on the operating member, and an inclined piece cut and raised in the housing part of the housing is formed on the lid, which operates in accordance with the pressing of the pressing part when the operating member is pressed. Since the operating part presses the reversing spring by sliding the part on the inclined piece and bending downward, the operating part that presses the reversing spring downward when the operating member slides is integrated with the operating member. Therefore, the push button switch can be thinned.
In addition, an inclined surface is formed in the operating portion of the operating member, and a swingable drive conversion member is provided in the housing housing portion. When the operating member is pressed, the inclined surface of the operating portion is moved along with the pressing of the pressing portion. Since the reversal spring is pressed by sliding with the drive conversion member and the drive conversion member bends downward, by providing a drive conversion member that can swing in contact with the operating portion, Since the drive conversion member can be moved in a direction intersecting the sliding direction, the reversing spring can be reliably pressed downward.

An operation member 6 described later is placed on the dustproof sheet 5, and the central portion 4 b of the movable contact 4 is pressed by the operating portion 6 a of the operation member 6 through the dustproof sheet 5.

操作部材６は、合成樹脂などの絶縁材からなり、この操作部材６には、略方形状で中央に開口部６ａを有する基台部６ｂと、この開口部６ａに片持ち梁状に突出した可撓性の作動部６ｃと、前記ハウジング１の切窓部１ｃより外方へ突出する押圧部６ｄとが形成されている。前記作動部６ｃは、薄肉状のアーム部６ｅを介して押圧部６ｄに連結されており、このアーム部６ｅが撓むことにより作動部６ｃが下方向に弾性変位可能となっている。 The operation member 6 is made of an insulating material such as a synthetic resin. The operation member 6 has a base portion 6b having a substantially square shape and an opening 6a at the center, and a cantilever protruding from the opening 6a. A flexible actuating part 6c and a pressing part 6d projecting outward from the cut window part 1c of the housing 1 are formed. The operating portion 6c is connected to the pressing portion 6d through a thin arm portion 6e, and the operating portion 6c can be elastically displaced downward by bending the arm portion 6e.

また、操作部材６は、前記ハウジング１の上面に載置された防塵シート５の上面に載置され、ハウジング１の切窓部１ｃから突出した押圧部６ｄが押圧されることにより、ハウジング１の収納部１ａ内に横方向にスライド移動可能に配設されている。また、押圧部６ｄには、押圧された時にハウジング１及び後述する蓋体７のストッパー面と当接するストッパー部６ｆが形成されており、また、基台部６ｂ後方には、後述する蓋体７に設けられた復帰ばね部７ｃと当接するばね受け部６ｇが設けられている。 The operation member 6 is placed on the upper surface of the dustproof sheet 5 placed on the upper surface of the housing 1, and the pressing portion 6 d protruding from the cut window portion 1 c of the housing 1 is pressed, whereby the housing 1 is stored. It is arranged in the part 1a so as to be slidable in the lateral direction. The pressing portion 6d is formed with a stopper portion 6f that comes into contact with the stopper surface of the housing 1 and a lid body 7 to be described later when pressed, and a lid body 7 to be described later is provided behind the base portion 6b. A spring receiving portion 6g is provided in contact with the return spring portion 7c provided on the front side.

蓋体７は、導電性の金属板を打ち抜き、折り曲げることにより形成されており、平板状の上板部７ａを有し、この上板部７ａの四隅からは下方に折り曲げられて、前記ハウジング１の上面側の四隅に設けられた前記突起１ｂとそれぞれ係合する、Ｌ字状の係合片部７ｂが設けられている。また、前記ハウジング１の背面側に配設された一対の係合片部７ｂ、７ｂの間には、両持ち梁状にばね性を有した状態で一方に膨出する復帰ばね部７ｃが形成されており、この復帰ばね部７ｃに前記操作部材６のばね受け部６ｇが当接することにより、操作部材６の押圧操作時に復帰力が付与されるものとなっている。
このように、復帰ばね部７ｃを、金属板からなる蓋体７に一体に形成したので、押釦スイッチの長寿命化が図れると共に、組立を簡単に行なうことができるものとなる。 The lid body 7 is formed by punching and bending a conductive metal plate, and has a flat plate-like upper plate portion 7a. The lid 1 is bent downward from the four corners of the upper plate portion 7a, and the housing 1 L-shaped engaging piece portions 7b are provided to engage with the protrusions 1b provided at the four corners on the upper surface side. Further, between the pair of engaging piece portions 7b, 7b disposed on the back side of the housing 1, a return spring portion 7c that bulges to one side while having a spring property in the form of a double-supported beam is formed. The spring receiving portion 6g of the operation member 6 abuts on the return spring portion 7c, so that a return force is applied when the operation member 6 is pressed.
Thus, since the return spring portion 7c is formed integrally with the lid body 7 made of a metal plate, the life of the push button switch can be extended and the assembly can be performed easily.

また、蓋体７の上板部７ａには、中央部よりハウジング１の収納部１ａ内側に切り起こされ、その先端側が前記操作部材６の基台部６ｂに設けられた開口部６ａに挿入されて、前記可動接点４の中央部４ｂと対向する傾斜片７ｄが形成されている。この傾斜片７ｄは、下方に折り曲げられて形成されており、この傾斜片７ｄの斜面に前記操作部材６の可撓性を有するアーム部６ｅの先端に設けられた作動部６ｃが摺動することにより、作動部６ｃが押し下げられて、可動接点４の中央部４ｂを下方へ押圧するようになっている。 Further, the upper plate portion 7 a of the lid body 7 is cut and raised from the center portion to the inside of the housing portion 1 a of the housing 1, and the distal end side thereof is inserted into the opening portion 6 a provided in the base portion 6 b of the operation member 6. Thus, an inclined piece 7d facing the central portion 4b of the movable contact 4 is formed. The inclined piece 7d is formed to be bent downward, and the operating portion 6c provided at the tip of the flexible arm portion 6e of the operating member 6 slides on the inclined surface of the inclined piece 7d. As a result, the operating portion 6c is pushed down to press the central portion 4b of the movable contact 4 downward.

尚、前記傾斜片７ｄを、前記蓋体７の上板部７ａを折り曲げることにより蓋体７に一体に形成するようにしたが、これに限らず、同様な傾斜面を有する合成樹脂などからなる成形材で部品を形成し、これを蓋体７の裏面側に一体的に係合することで作動部６ｃが摺動する傾斜面を形成するようにしても良い。また、この場合に、この成形部品に一体に前記復帰ばね部７ｃを設けるようにしても良く、この場合には、操作部材６と復帰ばね部７ｃとの当接位置、及び操作部材６の作動部６ｃと傾斜面との摺動位置関係を精度良く形成できるものとなる。
また、蓋体７に傾斜片７ｄを切り起こす際の開口部が形成されないので、防塵性を増すことができ、基板への装着時のエアー吸引を確実に行なえる。 The inclined piece 7d is formed integrally with the lid body 7 by bending the upper plate portion 7a of the lid body 7. However, the present invention is not limited to this and is made of a synthetic resin having a similar inclined surface. An inclined surface on which the operating portion 6c slides may be formed by forming a part with a molding material and integrally engaging the part with the back surface side of the lid body 7. In this case, the return spring portion 7c may be provided integrally with the molded part. In this case, the contact position between the operation member 6 and the return spring portion 7c and the operation of the operation member 6 may be provided. The sliding positional relationship between the portion 6c and the inclined surface can be formed with high accuracy.
Further, since no opening is formed in the lid body 7 when the inclined piece 7d is raised, dustproofness can be increased, and air suction can be reliably performed when the substrate 7 is mounted.

上記構成の押釦スイッチを組み立てるには、まず、ハウジング１の収納部１ａ内に可動接点４を載置し、この可動接点４上を防塵シート５で覆い、この防塵シート５の周囲をハウジング１の上面に貼り付ける。次に、この防塵シート５上に操作部材６を配置した後、蓋体７をハウジング１上に載置する。この時、それぞれの四隅に形成された、係合片部７ｂと突起１ｂとをそれぞれ嵌合させて蓋体７をハウジング１に係止させることにより組立が完了する。 In order to assemble the pushbutton switch having the above-described configuration, first, the movable contact 4 is placed in the housing 1a of the housing 1, the movable contact 4 is covered with the dustproof sheet 5, and the periphery of the dustproof sheet 5 is surrounded by the housing 1. Paste on top. Next, after the operation member 6 is disposed on the dustproof sheet 5, the lid body 7 is placed on the housing 1. At this time, the assembly is completed by engaging the engaging pieces 7b and the projections 1b formed at the four corners and locking the lid 7 to the housing 1, respectively.

次に、図５乃至図７を用いて上記構成の押釦スイッチの動作を説明する。尚、各図の（ａ）は操作部材６と復帰ばね部７ｃとの関係を示す要部平面説明図、各図の（ｂ）は全体の要部断面説明図である。
まず、操作部材６が非押圧時の初期の状態においては、図４に示すように、操作部材６の作動部６ｃは、蓋体７の傾斜片７ｄの折り曲げ部の根元近傍に位置しており、下方へは弾性変位されないで可動接点４と固定接点３とは離間した状態となっている。 Next, the operation of the pushbutton switch having the above configuration will be described with reference to FIGS. In addition, (a) of each figure is principal part explanatory drawing which shows the relationship between the operation member 6 and the return spring part 7c, (b) of each figure is a principal part sectional explanatory drawing.
First, in the initial state when the operating member 6 is not pressed, the operating portion 6c of the operating member 6 is located near the root of the bent portion of the inclined piece 7d of the lid 7 as shown in FIG. The movable contact 4 and the fixed contact 3 are separated from each other without being elastically displaced downward.

この状態から、操作部材６の押圧部６ｄを図５の右方向へ押圧すると、蓋体７よりハウジング１内側に切り起こされた傾斜片７ｄの斜面上を、操作部材６の作動部６ｃが摺動することにより案内され、これに伴い、作動部６ｃがアーム部６ｅで弾性変位しながら図５（ｂ）に示すように下（時計）方向へ回動するので、この作動部６ｃの先端が防塵シート５を介して可動接点４の中央部４ｂを押圧する。
これによって、反転ばねからなる可動接点４は下方へ反転してクリック感触が得られると共に、中央部４ｂが固定接点３と接触してスイッチがオンの状態となる。この時、操作部材６の背面側のばね受け部６ｇは、蓋体７の復帰ばね部７ｃには当接しておらず、操作部材６への復帰力は付与されない状態となっている。 From this state, when the pressing portion 6d of the operating member 6 is pressed rightward in FIG. 5, the operating portion 6c of the operating member 6 slides on the inclined surface of the inclined piece 7d cut and raised inside the housing 1 from the lid 7. Accordingly, the operating portion 6c rotates downward (clockwise) as shown in FIG. 5B while being elastically displaced by the arm portion 6e, so that the tip of the operating portion 6c is moved. The central portion 4 b of the movable contact 4 is pressed through the dustproof sheet 5.
As a result, the movable contact 4 formed of a reversing spring is reversed downward to obtain a click feeling, and the central portion 4b comes into contact with the fixed contact 3 and the switch is turned on. At this time, the spring receiving portion 6g on the back side of the operation member 6 is not in contact with the return spring portion 7c of the lid body 7, and the return force to the operation member 6 is not applied.

この状態から、押圧部６ｄを更に押圧すると、図６に示すようにスイッチがオンの状態のまま、操作部材６が図示右方向へスライド移動して背面側のばね受け部６ｇが蓋体７の復帰ばね部７ｃと当接して復帰ばね部７ｃが撓むことにより復帰力が付与される状態となる。
この状態から、更に押圧部６ｄを押圧すると、図７に示すように復帰ばね部７ｃが更に撓んで、押圧部６ｄのストッパー部６ｆがハウジング１と蓋体７のストッパー面に当接して操作部材６のスライド移動が停止される。この時には、復帰ばね部７ｃのばね性により操作部材６は図示左方向へ復帰力が付与された状態となっている。 When the pressing portion 6d is further pressed from this state, the operating member 6 slides to the right in the figure while the switch is on as shown in FIG. When the return spring portion 7c is bent in contact with the return spring portion 7c, a return force is applied.
When the pressing portion 6d is further pressed from this state, the return spring portion 7c is further bent as shown in FIG. 7, and the stopper portion 6f of the pressing portion 6d comes into contact with the stopper surfaces of the housing 1 and the lid body 7 to operate the operating member. 6 slide movement is stopped. At this time, due to the spring property of the return spring portion 7c, the operation member 6 is in a state in which a return force is applied in the left direction in the figure.

この状態から、押圧部６ｄの押圧状態を解除すると、操作部材６は復帰ばね部７ｃの復帰力により押し戻されて図示左方向へスライド移動されるものとなり、これに伴って、アーム部６ｅ自体の弾発力により作動部６ｃが図５（ｂ）の上（反時計）方向に回動しながら傾斜片７ｄの斜面上を摺動することにより、操作部材６が図５の左方向へスライド移動して図４に示す初期状態に復帰する。この時、作動部６ｃの回動に伴い、可動接点４の中央部４ｂも弾発力により上方へ反転復帰して固定接点３より離間し、スイッチがオフ状態となる。 When the pressing state of the pressing portion 6d is released from this state, the operation member 6 is pushed back by the return force of the return spring portion 7c and is slid to the left in the drawing, and accordingly, the arm portion 6e itself is moved. The operating member 6 slides to the left in FIG. 5 by sliding on the inclined surface of the inclined piece 7d while the operating portion 6c rotates upward (counterclockwise) in FIG. Then, the initial state shown in FIG. 4 is restored. At this time, with the rotation of the operating portion 6c, the central portion 4b of the movable contact 4 is also reversed and returned upward by the elastic force and is separated from the fixed contact 3, and the switch is turned off.

尚、上記実施例では、前記復帰ばね部７ｃを、前記蓋体７に形成して、前記操作部材６が前記可動接点４をスイッチ切換え位置へ反転させてオンさせるまでスライド移動した際に、前記操作部材６の背面側のばね受け部６ｇと前記蓋体７とが前記復帰ばね部７ｃを介して当接可能なように配置する構成としたが、これに限らず、操作部材６の背面側に復帰ばね部を形成して、蓋体７の内面にばね受け部を形成するようにしても良い。
このように、復帰ばね部７ｃを操作部材６あるいは蓋体７のどちらか一方に設けようにようにすれば、構成が簡易となり、組立性が向上される。 In the above embodiment, the return spring portion 7c is formed on the lid body 7, and when the operation member 6 slides until the movable contact 4 is turned to the switch switching position by turning it over, The configuration is such that the spring receiving portion 6g on the back side of the operation member 6 and the lid 7 can be brought into contact with each other via the return spring portion 7c. Alternatively, a return spring portion may be formed, and a spring receiving portion may be formed on the inner surface of the lid body 7.
Thus, if the return spring portion 7c is provided on either the operating member 6 or the lid 7, the configuration becomes simple and the assemblability is improved.

また、前記操作部材６に、操作部材６がスライド方向へ移動する際に前記ハウジング１及び蓋体７のストッパー面に当接するストッパー部６ｆを設け、前記操作部材６と蓋体７とが、前記復帰ばね部７ｃを介して当接してからストッパー部６ｆがストッパー面に当接するまでの間、前記復帰ばね部７ｃにより前記操作部材６へ復帰力を付与するようにしたことから、操作部材６のストッパー部６ｆがストッパー面と当接する位置にスライド移動するまで、前記復帰ばね部７ｃが連続して復帰力を付与するので、操作部材６のスライド移動後の復帰を確実に行なうことができるものとなっている。 The operating member 6 is provided with a stopper portion 6f that comes into contact with the stopper surfaces of the housing 1 and the lid body 7 when the operating member 6 moves in the sliding direction, and the operating member 6 and the lid body 7 Since the return spring portion 7c applies a return force to the operation member 6 from the time of contact through the return spring portion 7c until the stopper portion 6f contacts the stopper surface, The return spring portion 7c continuously applies a return force until the stopper portion 6f slides to a position where it abuts against the stopper surface, so that the operation member 6 can be reliably returned after the slide movement. It has become.

また、反転ばねの裏面に接点部を設けて前記可動接点４を形成し、前記ハウジング１の収納部１ａの内底面に前記固定接点２、３を設け、この固定接点２、３上に反転ばねからなる可動接点４を反復反転可能に配設し、前記操作部材６の押圧操作時に、作動部６ｃを介して可動接点４が反転して接点部が前記固定接点２、３と接触してスイッチ信号の切換えが行なわれると共に、それ以降、操作部材６がスライド移動した際に、前記復帰ばね部７ｃにより前記操作部材６へ復帰力を付与するようにしたことから、前記操作部材６がスイッチ信号の切換えが行なわれた後のスライド位置で、前記復帰ばね部７ｃが復帰力を付与するので、前記操作部材の復帰を確実に行なえ、所望のクリック感触を得ることができるものとなっている。 Further, a contact portion is provided on the back surface of the reversing spring to form the movable contact 4, the fixed contacts 2 and 3 are provided on the inner bottom surface of the housing portion 1 a of the housing 1, and the reversing spring is provided on the fixed contacts 2 and 3. The movable contact 4 is arranged so as to be repeatedly reversible, and when the operation member 6 is pressed, the movable contact 4 is reversed via the actuating portion 6c so that the contact portion contacts the fixed contacts 2 and 3 and is switched. Since the switching of the signal is performed, and thereafter, when the operation member 6 slides, the return spring portion 7c applies a return force to the operation member 6, so that the operation member 6 receives the switch signal. Since the return spring portion 7c applies a return force at the slide position after the switching of the operation, the operation member can be reliably returned and a desired click feeling can be obtained.

また、前記操作部材６に可撓性を有する作動部６ｃを形成し、前記蓋体７にはハウジング１の収納部１ａ内に切り起こされた傾斜片７ｄを形成して、前記操作部材６の押圧操作時には、押圧部６ｄの押圧に伴って、前記作動部６ｃが前記傾斜片７ｄ上を摺動して下方へ撓むことで、作動部６ｃが可動接点４を押圧するようにしたことから、前記操作部材６のスライド操作時に、前記可動接点４を下方へ押圧する作動部６ｃを操作部材６に一体的に形成できるので、押釦スイッチの薄型化が図れるものとなっている。 In addition, the operating member 6 is formed with a flexible operating portion 6 c, and the lid 7 is formed with an inclined piece 7 d cut and raised in the housing portion 1 a of the housing 1. At the time of the pressing operation, as the pressing portion 6d is pressed, the operating portion 6c slides on the inclined piece 7d and bends downward, so that the operating portion 6c presses the movable contact 4. Since the operating portion 6c that presses the movable contact 4 downward can be formed integrally with the operating member 6 when the operating member 6 is slid, the push button switch can be made thinner.

本実施例の構成と、上記した第一の実施例の構成とで異なる点は、操作部材の作動部の構成が一部相違する点と駆動変換部材を設けた点である。
尚、上記した第一の実施例と同一の構成部品については同一の符号を付してその詳細な説明は省略する。 The difference between the configuration of the present embodiment and the configuration of the first embodiment described above is that the configuration of the operating portion of the operation member is partially different from that of the first embodiment.
The same components as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

図８乃至図１０に示す、押し釦スイッチは、収納部を有するハウジング１と、収納部の内底面に対向して設けられた固定接点２、３と、これら固定接点２、３上に配設された反転ばねからなる可動接点４と、この可動接点４上に設けられ、ポリイミド等からなる防塵シート５と、この防塵シート５を介して可動接点４を作動させる駆動変換部材８と、この駆動変換部材８を駆動する操作部材９と、前記ハウジング１の上面に取付けられ、前記収納部を覆う蓋体７とから構成されている。尚、ハウジング１と蓋体７とでスイッチの筐体を構成している。 The push button switch shown in FIGS. 8 to 10 is disposed on the housing 1 having a storage portion, fixed contacts 2 and 3 provided to face the inner bottom surface of the storage portion, and the fixed contacts 2 and 3. A movable contact 4 made of a reversing spring, a dustproof sheet 5 made of polyimide or the like provided on the movable contact 4, a drive conversion member 8 for operating the movable contact 4 via the dustproof sheet 5, and this drive An operation member 9 that drives the conversion member 8 and a lid 7 that is attached to the upper surface of the housing 1 and covers the storage portion. The housing 1 and the lid 7 constitute a switch housing.

操作部材９は、合成樹脂などの絶縁材からなり、この操作部材９には、略方形状で中央に開口部９ａを有する基台部９ｂと、この開口部９ａの一内面に設けられた傾斜面を有する作動部９ｃと、前記ハウジング１の切窓部１ｃより外方へ突出する押圧部９ｄとが形成されている。 The operation member 9 is made of an insulating material such as a synthetic resin. The operation member 9 includes a base portion 9b having a substantially square shape and an opening 9a at the center, and an inclination provided on one inner surface of the opening 9a. An actuating part 9c having a surface and a pressing part 9d protruding outward from the cut window part 1c of the housing 1 are formed.

また、操作部材９は、前記ハウジング１の上面に載置された防塵シート５の上面に載置され、ハウジング１の切窓部１ｃから突出した押圧部９ｄが押圧されることにより、ハウジング１の収納部１ａ内に横方向にスライド移動可能に配設されている。また、押圧部９ｄには、押圧された時にハウジング１及び後述する蓋体７のストッパー面と当接するストッパー部９ｅが形成されており、また、基台部９ｂ後方には、蓋体７に設けられた復帰ばね部７ｃと当接するばね受け部９ｆが設けられている。 The operation member 9 is placed on the upper surface of the dustproof sheet 5 placed on the upper surface of the housing 1, and the pressing portion 9 d protruding from the cut window portion 1 c of the housing 1 is pressed, whereby the housing 1 is stored. It is arranged in the part 1a so as to be slidable in the lateral direction. The pressing portion 9d is formed with a stopper portion 9e that comes into contact with the stopper surface of the housing 1 and a lid body 7 to be described later when pressed, and is provided on the lid body 7 behind the base portion 9b. A spring receiving portion 9f that comes into contact with the return spring portion 7c is provided.

尚、本実施例の蓋体７は、導電性の金属板を打ち抜き、折り曲げることにより形成され、平板状の上板部７ａを有し、Ｌ字状の係合片部７ｂと、一方に膨出する復帰ばね部７ｃが形成されている構成においては上記した第一実施例の構成と同一であるが、蓋体７の上板部７ａには、中央部よりハウジング１の収納部１ａ内側に切り起こされた傾斜片７ｄは設けられておらず。この点が一部相違している。その為、蓋体７の上面に開口が形成されないため、防塵性を増すことができ、基板への実装時に、マウンタでのエアー吸引を確実に行なえ、実装精度を高めることができる。 The lid body 7 of this embodiment is formed by punching and bending a conductive metal plate, has a flat plate-like upper plate portion 7a, and has an L-shaped engagement piece portion 7b and a bulge in one side. The configuration in which the return spring portion 7c is formed is the same as the configuration of the first embodiment described above, but the upper plate portion 7a of the lid body 7 is located inside the housing portion 1a of the housing 1 from the center portion. The cut and raised inclined piece 7d is not provided. This is partly different. For this reason, since no opening is formed on the upper surface of the lid 7, dustproofness can be increased, air can be reliably sucked by the mounter during mounting on the substrate, and mounting accuracy can be improved.

駆動変換部材８は、弾性を有する薄板金属板からなり、平板状の基板部８ａとこの基板部８ａの上面側に突出して形成された円環状の駆動部８ｂとを有している。この駆動変換部材８は、前記ハウジング１の上面に載置された防塵シート５の上面に載置され、ハウジング１と蓋体７との間に挟持されている。また、駆動変換部材８の上面側には、駆動部８ｂと傾斜面の作動部９ｃが当接された状態で、操作部材９がスライド移動可能に配置されている。
そして、操作部材９が押圧された際には、作動部９ｃの傾斜面と駆動部８ｂとが摺動することにより、駆動部８ｂが押し下げられて、可動接点４の中央部４ｂを下方へ押圧するようになっている。 The drive conversion member 8 is made of an elastic thin metal plate, and has a flat plate-like substrate portion 8a and an annular drive portion 8b formed to protrude from the upper surface side of the substrate portion 8a. The drive conversion member 8 is placed on the upper surface of the dustproof sheet 5 placed on the upper surface of the housing 1, and is sandwiched between the housing 1 and the lid body 7. Further, the operation member 9 is slidably disposed on the upper surface side of the drive conversion member 8 in a state where the drive portion 8b and the inclined operation portion 9c are in contact with each other.
When the operation member 9 is pressed, the driving portion 8b is pushed down by sliding the inclined surface of the operating portion 9c and the driving portion 8b, and the central portion 4b of the movable contact 4 is pressed downward. It is supposed to be.

上記構成の押釦スイッチを組み立てるには、まず、ハウジング１の収納部１ａ内に可動接点４を載置し、この可動接点４上を防塵シート５で覆い、この防塵シート５の周囲をハウジング１の上面に貼り付ける。次に、この防塵シート５上に駆動変換部材８と操作部材９を配置した後、蓋体７をハウジング１上に載置する。この時、それぞれの四隅に形成された、係合片部７ｂと突起１ｂとをそれぞれ嵌合させて蓋体７をハウジング１に係止させることにより組立が完了する。 In order to assemble the pushbutton switch having the above-described configuration, first, the movable contact 4 is placed in the housing 1a of the housing 1, the movable contact 4 is covered with the dustproof sheet 5, and the periphery of the dustproof sheet 5 is surrounded by the housing 1. Paste on top. Next, after the drive conversion member 8 and the operation member 9 are disposed on the dustproof sheet 5, the lid body 7 is placed on the housing 1. At this time, the assembly is completed by engaging the engaging pieces 7b and the projections 1b formed at the four corners and locking the lid 7 to the housing 1, respectively.

次に、図１１乃至図１３を用いて上記構成の押釦スイッチの動作を説明する。尚、各図の（ａ）は操作部材９と復帰ばね部７ｃとの関係を示す要部平面説明図、各図の（ｂ）は全体の要部断面説明図である。
まず、操作部材９が非押圧時の初期の状態においては、図１０に示すように、駆動変換部材８の駆動部８ｂは操作部材９の作動部９ｃの傾斜面の上部近傍に位置しており、下方へは弾性変位されないで可動接点４と固定接点３とは離間した状態となっている。 Next, the operation of the pushbutton switch having the above configuration will be described with reference to FIGS. In addition, (a) of each figure is principal part plane explanatory drawing which shows the relationship between the operation member 9 and the return spring part 7c, (b) of each figure is a principal part sectional explanatory drawing.
First, in the initial state when the operation member 9 is not pressed, the drive portion 8b of the drive conversion member 8 is located near the upper portion of the inclined surface of the operation portion 9c of the operation member 9 as shown in FIG. The movable contact 4 and the fixed contact 3 are separated from each other without being elastically displaced downward.

この状態から、操作部材９の押圧部９ｄを図１１の右方向へ押圧すると、作動部９ｃの傾斜面上を、駆動変換部材８の駆動部８ｂが摺動することにより案内され、これに伴い、駆動部８ｂが弾性変位しながら図１１（ｂ）に示すように下方向へ回動するので、この駆動部８ｂの下端が防塵シート５を介して可動接点４の中央部４ｂを押圧する。
これによって、反転ばねからなる可動接点４は下方へ反転してクリック感触が得られると共に、中央部４ｂが固定接点３と接触してスイッチがオンの状態となる。この時、操作部材９の背面側のばね受け部９ｆは、蓋体７の復帰ばね部７ｃには当接しておらず、操作部材９への復帰力は付与されない状態となっている。 From this state, when the pressing portion 9d of the operating member 9 is pressed in the right direction in FIG. 11, the driving portion 8b of the drive conversion member 8 is guided by sliding on the inclined surface of the operating portion 9c. Since the driving portion 8b is rotated downward as shown in FIG. 11B while being elastically displaced, the lower end of the driving portion 8b presses the central portion 4b of the movable contact 4 via the dustproof sheet 5.
As a result, the movable contact 4 formed of a reversing spring is reversed downward to obtain a click feeling, and the central portion 4b comes into contact with the fixed contact 3 and the switch is turned on. At this time, the spring receiving portion 9f on the back side of the operation member 9 is not in contact with the return spring portion 7c of the lid body 7, and the return force to the operation member 9 is not applied.

この状態から、押圧部９ｄを更に押圧すると、図１２に示すようにスイッチがオンの状態のまま、操作部材９が図示右方向へスライド移動して背面側のばね受け部９ｆが蓋体７の復帰ばね部７ｃと当接して復帰ばね部７ｃが撓むことにより復帰力が付与される状態となる。
この状態から、更に押圧部９ｄを押圧すると、図１３に示すように復帰ばね部７ｃが更に撓んで、押圧部９ｄのストッパー部９ｅがハウジング１と蓋体７のストッパー面に当接して操作部材９のスライド移動が停止される。この時には、復帰ばね部７ｃのばね性により操作部材９は図示左方向へ復帰力が付与された状態となっている。 When the pressing portion 9d is further pressed from this state, the operating member 9 slides to the right in the figure while the switch is on as shown in FIG. When the return spring portion 7c is bent in contact with the return spring portion 7c, a return force is applied.
When the pressing portion 9d is further pressed from this state, the return spring portion 7c is further bent as shown in FIG. 13, and the stopper portion 9e of the pressing portion 9d comes into contact with the stopper surfaces of the housing 1 and the lid body 7 to operate the operating member. 9 slide movement is stopped. At this time, due to the spring property of the return spring portion 7c, the operation member 9 is in a state where a return force is applied in the left direction in the figure.

この状態から、押圧部９ｄの押圧状態を解除すると、操作部材９は復帰ばね部７ｃの復帰力により押し戻されて図示左方向へスライド移動されるものとなり、これに伴って、駆動部８ｂ自体の弾発力により駆動部８ｂが図１１（ｂ）の上方向に回動しながら作動部９ｃの傾斜面上を摺動することにより、操作部材９が図１１の左方向へスライド移動して図１０に示す初期状態に復帰する。この時、駆動部８ｂの回動に伴い、可動接点４の中央部４ｂも弾発力により上方へ反転復帰して固定接点３より離間し、スイッチがオフ状態となる。 When the pressing state of the pressing portion 9d is released from this state, the operating member 9 is pushed back by the return force of the return spring portion 7c and is slid in the left direction in the drawing. The operating member 9 slides in the left direction in FIG. 11 by sliding the driving portion 8b on the inclined surface of the operating portion 9c while rotating upward in FIG. 10 returns to the initial state. At this time, with the rotation of the drive unit 8b, the central part 4b of the movable contact 4 is also reversed and returned upward by the elastic force and is separated from the fixed contact 3, and the switch is turned off.

このように、本実施例においては、前記操作部材９の作動部９ｃに傾斜面を形成し、前記ハウジング１の収納部１ａには揺動可能な駆動変換部材８を設け、操作部材９の押圧操作時に、押圧部９ｄの押圧に伴って作動部９ｃの傾斜面が駆動変換部材８の駆動部８ｂと摺動し、この駆動部８ｂが下方へ撓むことで反転ばねからなる可動接点４を押圧するようにしたことから、前記操作部材９の作動部９ｃと当接して揺動可能な前記駆動変換部材８を設けることにより、前記操作部材９のスライド方向と交差する方向に前記駆動変換部材８を移動できるので、確実に可動接点４を下方へ押圧することができるものとなっている。 Thus, in this embodiment, the operating portion 9c of the operating member 9 is formed with an inclined surface, and the housing 1a of the housing 1 is provided with the swingable drive conversion member 8 so that the operating member 9 is pressed. During operation, the inclined surface of the actuating portion 9c slides with the driving portion 8b of the drive converting member 8 in accordance with the pressing of the pressing portion 9d. Since it is configured to be pressed, by providing the drive conversion member 8 that can swing in contact with the operating portion 9 c of the operation member 9, the drive conversion member in a direction intersecting the sliding direction of the operation member 9. Since 8 can be moved, the movable contact 4 can be surely pressed downward.

上記した本発明の実施例によれば、前記操作部材６、９を押圧操作する際には、前記操作部材６、９が反転ばねからなる可動接点４をスイッチ切換え位置へ反転させるまでスライド移動した後に当接すると共に、それ以降、スライド移動した操作部材６、９への復帰力を連続して付与する復帰ばね部７ｃを設けたことから、押釦スイッチの復帰操作を、反転した可動接点４の自らの反転復帰する蓄力による操作部材６、９への付勢力に加えて、前記復帰ばね部７ｃの復帰力とによって前記操作部材６、９の復帰を行なうようにしたので、操作部材６、９の復帰を確実に行うことができるものとなっている。
また、前記可動接点４のスイッチ切換え位置への反転動作途上においては、前記操作部材６、９に前記復帰ばね部７ｃの付勢力は作用しないため、所望のクリック感触を得ることができるものとなっている。 According to the embodiment of the present invention described above, when the operation members 6 and 9 are pressed, the operation members 6 and 9 are slid until the movable contact 4 formed of a reversing spring is reversed to the switch switching position. Since the return spring portion 7c that abuts afterward and continuously applies a return force to the slidably moved operation members 6 and 9 thereafter is provided, the return operation of the push button switch is performed by the inverted movable contact 4 itself. In addition to the urging force applied to the operation members 6 and 9 by the stored force of reversing and returning, the operation members 6 and 9 are returned by the return force of the return spring portion 7c. Can be reliably restored.
Further, during the reversing operation of the movable contact 4 to the switch switching position, the urging force of the return spring portion 7c does not act on the operation members 6 and 9, so that a desired click feeling can be obtained. ing.
