特開２００７−３２４０９０号公報JP 2007-324090 A

プッシュスイッチ９００は、キートップ９３２を押圧した方向に、折込片９５８の先端部同士が対向して状態で、折込片９５８の先端部の下側がプリント基板９２６の後方固定ランド９５３に半田付けで固定されている。そのため、強めの力でキートップ９３２が押圧されたとしても、折込片９５８が広がって固定が緩むことは無い。しかしながら、昨今、携帯型の電子機器においては多機能化などに伴い、限られたスペースにより多くの電子部品を実装する為に、より小型のプッシュスイッチが求められている。特許文献１に記載のプッシュスイッチ９００と同じ構造で小型化した場合、金属カバー９３３の板厚が薄くなったり、半田付け可能な面積が小さくなったりする。そのため、小型化する前には問題の無かったレベルの強めの力でキートップ９３２が押圧された場合に、半田付けが外れないまでも、後方固定ランド９５３に半田付けがされていない折込片９５８の先端部の上側が広がり、ケース９２７に対する金属カバー９３３の保持が弱まることが懸念される。仮に、このようにケース９２７に対する金属カバー９３３の保持が弱まると、操作はできるが接触片９３０を介した中央電極とサイド電極との接離のタイミングがずれたり、操作感触が悪くなったりするなどの不具合が発生する。 The push switch 900 is fixed by soldering to the rear fixed land 953 of the printed circuit board 926 with the lower ends of the folded pieces 958 facing each other in the direction in which the key top 932 is pressed. Has been. Therefore, even if the key top 932 is pressed with a strong force, the folding piece 958 does not spread and the fixing is not loosened. However, in recent years, with the increase in functionality in portable electronic devices, a smaller push switch is required in order to mount more electronic components in a limited space. In the case of downsizing with the same structure as the push switch 900 described in Patent Document 1, the thickness of the metal cover 933 is reduced, and the solderable area is reduced. Therefore, when the key top 932 is pressed with a strong force of a level that had no problem before downsizing, the folded piece 958 that is not soldered to the rear fixed land 953 until the soldering is not removed. There is a concern that the upper side of the front end of the metal plate spreads and the holding of the metal cover 933 on the case 927 is weakened. If the holding of the metal cover 933 with respect to the case 927 is weakened in this way, the operation can be performed, but the contact / separation timing of the center electrode and the side electrode via the contact piece 930 is shifted, or the operation feeling is deteriorated. The problem occurs.

本発明は、上述した課題を解決して、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供するものである。 The present invention solves the above-described problems and provides a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.

It was set as the structure integrated by engaging. Thereby, since the part where the rear cover member was pressed and expanded is not spread, the pushing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.

請求項２の発明によれば、係合部を切り欠きからなる係合凹部とすることで、係合部を簡易に構成することができる。また、後方カバー部材の腕部が係合凹部の上下の内壁に当接するように係合する構成とすることで、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる、という効果を奏する。 According to invention of Claim 2, an engaging part can be comprised simply by making an engaging part into the engaging recessed part which consists of notches. In addition, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force by adopting a configuration in which the arms of the rear cover member are engaged so as to contact the upper and lower inner walls of the engagement recess. . Therefore, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force with a simple configuration.

請求項３の発明によれば、係合凹部の上下方向で対向する面部同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成され、先端が上下方向に２股に分割された係合端部が係合凹部に挿入され、係合端部を係合凹部の上下方向で対向する面部と当接するように押し広げて、前方カバー部材と後方カバー部材とが係合される構成とした。係合端部を上下方向に押し広げて、前方カバー部材と後方カバー部材と係合させると、係合凹部の上下方向で対向する面部同士の間隔が広い側の係合端部は、係合凹部の上下方向で対向する面部同士の間隔が狭い側の係合端部よりも広くなるように広げられる。これにより、係合端部はそれぞれ捻じられた様にひろげられ、係合端部と係合凹部との係合はより強固となり、押圧方向には外れにくくなる。また、係合凹部の上下方向で対向する面部同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成されているため、幅方向外方側に対しても係合は外れにくくなっている。したがって、基板取り付け後に前方側からの押圧操作に対してより耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 According to the invention of claim 3, the interval between the surface portions facing each other in the vertical direction of the engaging concave portion is formed so as to become narrower toward the outer side in the width direction, and the tip is divided into two forks in the vertical direction. The engagement end portion is inserted into the engagement recess, and the engagement end is expanded so as to come into contact with the surface portion facing the vertical direction of the engagement recess, so that the front cover member and the rear cover member are engaged. The configuration. When the engagement end portion is pushed up and down and engaged with the front cover member and the rear cover member, the engagement end portion on the side where the surface portions facing each other in the vertical direction of the engagement recess are wide is engaged. It is expanded so that the space | interval of the surface parts facing in the up-down direction of a recessed part may become wider than the engagement edge part of the narrow side. As a result, the engagement end portions are spread as if they were twisted, and the engagement between the engagement end portion and the engagement concave portion becomes stronger, and it is difficult to disengage in the pressing direction. In addition, since the interval between the surface portions facing each other in the vertical direction of the engagement concave portion is formed so as to narrow toward the outer side in the width direction, the engagement is not easily released even on the outer side in the width direction. It has become. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached.

請求項４の発明によれば、係合部を貫通孔からなる係合穴部とすることで、係合部を簡易に構成することができる。また、後方カバー部材の腕部が係合穴部に挿入され、折り曲げることで係合する構成とすることで、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる、という効果を奏する。 According to invention of Claim 4, an engaging part can be comprised simply by making an engaging part into the engaging hole part which consists of a through-hole. In addition, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force by adopting a configuration in which the arm portion of the rear cover member is inserted into the engagement hole portion and bent. Therefore, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force with a simple configuration.

請求項５の発明によれば、係合穴部の開口形状を、幅方向における外方側が円弧形状とすることで、幅方向における外方側においては上下方向の寸法が内方側よりも小さくなるので、係合穴部と腕部とを係合するときに、腕部が係合穴部の幅方向における外方側の面に接触すると、腕部は内方側へ寄せられる。したがって、前方カバー部材と後方カバー部材とをガタのない状態で固定することができ、外れにくい強固な係合とすることができる、という効果を奏する。 According to the fifth aspect of the present invention, the opening shape of the engagement hole portion is an arc shape on the outer side in the width direction, so that the vertical dimension is smaller on the outer side in the width direction than on the inner side. Therefore, when the engagement hole and the arm are engaged with each other, if the arm contacts the outer surface in the width direction of the engagement hole, the arm is moved inward. Therefore, there is an effect that the front cover member and the rear cover member can be fixed without any backlash, and a strong engagement that is difficult to come off can be obtained.

請求項６の発明によれば、第１半田付け部と第２半田付け部とを設けるとともに、第１半田付け部と第２半田付け部とが僅かな隙間を有して隣り合って配置されることで、第１半田付け部と第２半田付け部とを半田付けした際に、前方カバー部材と後方カバー部材とは半田により連結される。そのため、操作部材を強い力で押圧された場合にも、係合端部と係合凹部との係合箇所にかかる負荷が半田により連結された部分に分散されるため、係合端部と係合凹部との係合は外れにくくなる。したがって、基板取り付け後に前方側からの押圧操作に対してさらに耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 According to the invention of claim 6, the first soldering portion and the second soldering portion are provided, and the first soldering portion and the second soldering portion are arranged adjacent to each other with a slight gap. Thus, when the first soldering portion and the second soldering portion are soldered, the front cover member and the rear cover member are connected by solder. For this reason, even when the operation member is pressed with a strong force, the load applied to the engagement portion between the engagement end portion and the engagement recess portion is distributed to the portion connected by the solder. Engagement with the joint recess is difficult to disengage. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached.

請求項７の発明によれば、第１逃げ部および第２逃げ部を設けることで、プッシュスイッチを基板に半田付けする際に発生するフラックスが、第１逃げ部および第２逃げ部を伝わるため、フラックスがケースの空間部に到達するまでの距離を長くしたり、フラックスを空間部とは異なる方向へ誘導することができる。よって、空間部内にフラックスが入り込みにくくなり、フラックスの付着による可動接点部材と固定接点部との導通不良の発生を少なくすることができる。したがって、安定したスイッチングができるプッシュスイッチを提供することができる、という効果を奏する。 According to the seventh aspect of the present invention, since the first relief portion and the second relief portion are provided, the flux generated when the push switch is soldered to the substrate is transmitted through the first relief portion and the second relief portion. The distance until the flux reaches the space of the case can be increased, or the flux can be guided in a direction different from the space. Therefore, it becomes difficult for flux to enter the space portion, and occurrence of poor conduction between the movable contact member and the fixed contact portion due to adhesion of the flux can be reduced. Therefore, it is possible to provide a push switch capable of stable switching.

以上より、本発明によれば、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供することができる。 As described above, according to the present invention, it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.

次にプッシュスイッチ１００の構造について図２、図３および図１１を用いて説明する。図１１は図３（ｂ）に示す断面Ｂ−Ｂを示す模式断面図である。なお、可動接点部材２の断面部は２枚分をまとめて１つの断面で表している。 Next, the structure of the push switch 100 will be described with reference to FIGS. FIG. 11 is a schematic cross-sectional view showing a cross section BB shown in FIG. In addition, the cross-sectional part of the movable contact member 2 is represented by one cross section for two sheets.

図１１に示すように、２枚重ねられた可動接点部材２は第２ケース部材３ｆの第２空間部３ｍ内に配置される。可動接点部材２は可動接点部２ａが前方（Ｘ１方向）へ突出する向きに配置され、常接接点部２ｃは第２空間部３ｍの後方側の内壁に露出する第２固定接点部３ｐと接触している。なお、可動接点部２ａは第１固定接点部３ｎとは離間している。シート部材６は、粘着面６ａが第２空間部３ｍに対向する向きで、可動接点部材２が配置された第２空間部３ｍを覆うように配置される。シート部材６は粘着面６ａの粘着力により第２ケース部材３ｆに保持されるとともに、可動接点部材２を第２空間部３ｍ内に保持する。シート部材６は屈曲性を有しているため、シート部材６を介して押圧された場合には、可動接点部材２の可動接点部２ａは第２空間部３ｍ内でも可動可能に保持されている。操作部材１は、ボタン部１ａを第１空間部３ｋ側から開口部３ｇに挿通した状態で、第１ケース部材３ｅの第１空間部３ｋ内に保持される。第１空間部３ｋ内に操作部材１を保持した第１ケース部材３ｅは、操作部材１のアクチュエータ部１ｃがシート部材６と対向する向きで、シート部材６を第２ケース部材３ｆと挟み込み、第１空間部３ｋと第２空間部３ｍとが空間部３ｂを形成するように係合する。このように第１ケース部材３ｅと第２ケース部材３ｆとを係合することで、操作部材１のアクチュエータ部１ｃと可動接点部材２の可動接点部２ａとはシート部材６を介して接触する。また、前方カバー部材４は、貫通穴４ａに操作部材１のボタン部１ａを挿通させるとともに、位置決め孔部４ｅ（図１０参照）にそれぞれ第１ケース部材３ｅの位置決め凸部３ｈを挿通させて、空間部３ｂを覆うように第１ケース部材３ｅと係合している。また、後方カバー部材５は、基部５ａでケース３（第２ケース部材３ｆ）の後方側を覆うとともに、腕部５ｂを前方に延出させた状態で第２ケース部材３ｆと係合している。また前方へ延出した腕部５ｂが、前方カバー部材４の係合部４Ａ（係合凹部４ｂ）にそれぞれ係合されて前方カバー部材４と後方カバー部材５とが一体化されている。なお、係合端部５ｃは係合部４Ａである係合凹部４ｂに挿入されて、図３（ｂ）に示すように、係合凹部４ｂの上下方向で対向する内壁である面部４ｃと当接するように押し広げられ、係合している。このように係合端部５ｃが押し広げられ、係合凹部４ｂと当接することで前方カバー部材４と後方カバー部材５とが一体化されている。また、係合端部５ｃが押し広げられ、係合凹部４ｂと当接することで、第１ケース部材３ｅと第２ケース部材３ｆとは、シート部材６を圧接挟持する。このようにして第１実施形態におけるプッシュスイッチ１００は構成される。プッシュスイッチ１００は、図３（ｂ）に示すように、第１半田付け部４ｄと第２半田付け部５ｄとは、僅かな隙間Ｄを有して隣り合って配置されている。また、ケース３の、第１半田付け部４ｄおよび第２半田付け部５ｄと対向する箇所には、図２（ｂ）に示すように、凹形状に形成された第１逃げ部３ｃが設けられ、ケース３の下面（Ｚ２方向側の面）には、幅方向（Ｙ１−Ｙ２方向）に溝状に延設された第２逃げ部３ｄが設けられている。 As shown in FIG. 11, the two movable contact members 2 stacked are disposed in the second space 3m of the second case member 3f. The movable contact member 2 is disposed in a direction in which the movable contact portion 2a protrudes forward (X1 direction), and the permanent contact portion 2c contacts the second fixed contact portion 3p exposed on the inner wall on the rear side of the second space portion 3m. doing. The movable contact portion 2a is separated from the first fixed contact portion 3n. The sheet member 6 is disposed so as to cover the second space portion 3m where the movable contact member 2 is disposed, with the adhesive surface 6a facing the second space portion 3m. The sheet member 6 is held by the second case member 3f by the adhesive force of the adhesive surface 6a, and holds the movable contact member 2 in the second space 3m. Since the sheet member 6 has flexibility, when the sheet member 6 is pressed through the sheet member 6, the movable contact portion 2a of the movable contact member 2 is movably held in the second space 3m. . The operating member 1 is held in the first space portion 3k of the first case member 3e in a state where the button portion 1a is inserted through the opening 3g from the first space portion 3k side. The first case member 3e holding the operation member 1 in the first space 3k sandwiches the sheet member 6 with the second case member 3f with the actuator portion 1c of the operation member 1 facing the sheet member 6, and second The 1 space part 3k and the 2nd space part 3m engage so that the space part 3b may be formed. By engaging the first case member 3e and the second case member 3f in this way, the actuator portion 1c of the operation member 1 and the movable contact portion 2a of the movable contact member 2 are in contact via the sheet member 6. Further, the front cover member 4 allows the button portion 1a of the operation member 1 to be inserted into the through hole 4a, and allows the positioning convex portion 3h of the first case member 3e to be inserted into the positioning hole portion 4e (see FIG. 10). The first case member 3e is engaged so as to cover the space 3b. The rear cover member 5 covers the rear side of the case 3 (second case member 3f) with the base portion 5a, and engages with the second case member 3f with the arm portion 5b extending forward. . Further, the arm portion 5b extending forward is engaged with the engagement portion 4A (engagement recess 4b) of the front cover member 4, and the front cover member 4 and the rear cover member 5 are integrated. The engaging end portion 5c is inserted into the engaging recess 4b which is the engaging portion 4A, and as shown in FIG. 3B, the engaging end 5c contacts the surface portion 4c which is the inner wall facing the engaging recess 4b in the vertical direction. It is spread and engaged so that it touches. In this way, the engagement end portion 5c is spread and contacted with the engagement recess 4b, whereby the front cover member 4 and the rear cover member 5 are integrated. In addition, the engagement end portion 5c is expanded and brought into contact with the engagement recess 4b, whereby the first case member 3e and the second case member 3f press-clamp the sheet member 6. In this way, the push switch 100 in the first embodiment is configured. As shown in FIG. 3B, in the push switch 100, the first soldering portion 4d and the second soldering portion 5d are arranged adjacent to each other with a slight gap D. Further, as shown in FIG. 2B, a first relief portion 3c formed in a concave shape is provided at a location of the case 3 facing the first soldering portion 4d and the second soldering portion 5d. The lower surface (surface on the Z2 direction side) of the case 3 is provided with a second relief portion 3d extending in a groove shape in the width direction (Y1-Y2 direction).

次にプッシュスイッチ１００の動作について図１１および図１２を用いて説明する。図１２は図１１に示す状態から押圧操作された後の状態を示す模式断面図である。 Next, the operation of the push switch 100 will be described with reference to FIGS. 11 and 12. 12 is a schematic cross-sectional view showing a state after a pressing operation is performed from the state shown in FIG.

図１１に示す状態は、プッシュスイッチ１００が操作されていない初期状態を示している。図１１に示す状態においては、常接接点部２ｃは第２固定接点部３ｐと接触しているが、可動接点部２ａは第１固定接点部３ｎとは離間している。つまり、図１１に示す状態は、第１固定接点部３ｎと第２固定接点部３ｐとの電気的な導通は無い状態である。図１１に示す状態から、図１２に示すように、操作部材１を後方側（Ｘ２方向）へ押圧すると、シート部材６を介して可動接点部２ａに接触するアクチュエータ部１ｃは可動接点部２ａを後方側へ押圧する。押圧された可動接点部２ａは後方側へ撓んだ後に反転し、第１固定接点部３ｎに接触する。可動接点部２ａと第１固定接点部３ｎとが接触することで、第１固定接点部３ｎと第２固定接点部３ｐとは、可動接点部材２を介して電気的に導通される。また、操作部材１への押圧を解除すると、可動接点部２ａの弾性力により、図１１に示す初期状態に復帰し、第１固定接点部３ｎと第２固定接点部３ｐとの電気的な導通は無い状態となる。このように、第１固定接点部３ｎと第２固定接点部３ｐとの電気的な導通状態を切り替えることで入力を行なうことができ、プッシュスイッチとして機能する。 The state shown in FIG. 11 shows an initial state where the push switch 100 is not operated. In the state shown in FIG. 11, the normal contact portion 2 c is in contact with the second fixed contact portion 3 p, but the movable contact portion 2 a is separated from the first fixed contact portion 3 n. That is, the state shown in FIG. 11 is a state where there is no electrical continuity between the first fixed contact portion 3n and the second fixed contact portion 3p. When the operation member 1 is pressed backward (X2 direction) from the state shown in FIG. 11, the actuator portion 1 c that contacts the movable contact portion 2 a via the sheet member 6 moves the movable contact portion 2 a. Press backwards. The pressed movable contact portion 2a bends backward and then reverses to contact the first fixed contact portion 3n. When the movable contact portion 2a and the first fixed contact portion 3n come into contact with each other, the first fixed contact portion 3n and the second fixed contact portion 3p are electrically connected via the movable contact member 2. Further, when the pressing on the operation member 1 is released, the initial state shown in FIG. 11 is restored by the elastic force of the movable contact portion 2a, and electrical conduction between the first fixed contact portion 3n and the second fixed contact portion 3p. There will be no state. Thus, an input can be performed by switching the electrical continuity between the first fixed contact portion 3n and the second fixed contact portion 3p, and the device functions as a push switch.

以下、本実施形態としたことによる効果について説明する。なお、図１３は第1実施形態における係合凹部４ｂと係合端部５ｃとの係合状態を示す模式図である。 Hereinafter, the effect by having set it as this embodiment is demonstrated. FIG. 13 is a schematic diagram showing an engagement state between the engagement recess 4b and the engagement end 5c in the first embodiment.

本実施形態のプッシュスイッチ１００では、操作部材１と、可動接点部材２と、固定接点部３ａを有し、操作部材１および可動接点部材２を収容可能で前方側が開放された空間部３ｂを備えるケース３と、空間部３ｂを覆う前方カバー部材４と、ケース３の後方側を覆う基部５ａと、基部５ａの両端から前方側にそれぞれ延出している腕部５ｂとを備える後方カバー部材５と、を有するプッシュスイッチにおいて、前方カバー部材４には、操作部材１が突出する貫通穴４ａと、両端側に後方カバー部材５の腕部５ｂと係合される係合部４Ａとが設けられており、前方カバー部材４の係合部４Ａに後方カバー部材５の腕部５ｂがそれぞれ係合されて前方カバー部材４と後方カバー部材５とが一体化されている、構成とした。 The push switch 100 according to this embodiment includes an operation member 1, a movable contact member 2, and a fixed contact portion 3a, and includes a space portion 3b that can accommodate the operation member 1 and the movable contact member 2 and that is open on the front side. A rear cover member 5 including a case 3, a front cover member 4 covering the space portion 3b, a base portion 5a covering the rear side of the case 3, and arm portions 5b extending from both ends of the base portion 5a to the front side, respectively In the push switch having the above, the front cover member 4 is provided with a through hole 4a from which the operation member 1 protrudes, and an engagement portion 4A to be engaged with the arm portion 5b of the rear cover member 5 at both ends. The arm portion 5b of the rear cover member 5 is engaged with the engaging portion 4A of the front cover member 4 so that the front cover member 4 and the rear cover member 5 are integrated.

これにより、後方カバー部材５の基部５ａがケース３の後方側を覆う、すなわちケース３の後方側には後方カバー部材５が分断された箇所が無いとともに、２つの腕部５ｂを前方カバー部材４と係合させて一体化させる構成とした。これにより、押圧されて後方カバー部材５の分断された箇所が広がることはないので、先行技術に比べて前方側からの押し込み強度を向上させることができる。よって、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 Accordingly, the base portion 5a of the rear cover member 5 covers the rear side of the case 3, that is, the rear portion of the case 3 has no part where the rear cover member 5 is divided, and the two arm portions 5b are connected to the front cover member 4. To be integrated with each other. Thereby, since the part where the rear cover member 5 was pressed and spread does not spread, the pushing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.

また、本実施形態のプッシュスイッチ１００では、操作部材１と、可動接点部材２と、固定接点部３ａを有し、操作部材１および可動接点部材２を収容可能で前方側が開放された空間部３ｂを備えるケース３と、空間部３ｂを覆う前方カバー部材４と、ケース３の後方側を覆う基部５ａと、基部５ａの両端から前方側にそれぞれ延出している腕部５ｂとを備える後方カバー部材５と、を有するプッシュスイッチにおいて、前方カバー部材４には、操作部材１が突出する貫通穴４ａと、両端に後方カバー部材５の腕部５ｂと係合される係合凹部４ｂとが設けられており、前方カバー部材４の係合凹部４ｂに後方カバー部材５の腕部５ｂがそれぞれ係合されて前方カバー部材４と後方カバー部材５とが一体化されている、構成とした。
また、本実施形態のプッシュスイッチ１００では、係合部４Ａが切り欠きからなる係合凹部４ｂであり、後方カバー部材５の腕部５ｂが係合凹部４ｂの上下の内壁に当接するように係合している、構成とした。 Further, in the push switch 100 of the present embodiment, the operation member 1, the movable contact member 2, and the fixed contact portion 3a, the operation member 1 and the movable contact member 2 can be accommodated, and the space portion 3b opened on the front side. A rear cover member comprising: a case 3 including: a front cover member 4 that covers the space 3b; a base portion 5a that covers the rear side of the case 3; and an arm portion 5b that extends from both ends of the base portion 5a to the front side. 5, the front cover member 4 is provided with a through hole 4a from which the operation member 1 protrudes, and engagement recesses 4b engaged with the arm portions 5b of the rear cover member 5 at both ends. The arm 5b of the rear cover member 5 is engaged with the engagement recess 4b of the front cover member 4 so that the front cover member 4 and the rear cover member 5 are integrated.
Further, in the push switch 100 of the present embodiment, the engaging portion 4A is the engaging recess 4b formed by a notch, and the arm portion 5b of the rear cover member 5 is engaged with the upper and lower inner walls of the engaging recess 4b. The configuration is matched.

これにより、後方側カバー部材の基部５ａがケース３の後方側を覆う、すなわちケース３の後方側には後方側カバー部材が分断された箇所が無いとともに、２つの腕部５ｂを前方側カバー部材と係合させて一体化させる構成とした。これにより、押圧されて後方側カバー部材の分断された箇所が広がることはないので、先行技術に比べて前方側からの押し込み強度を向上させることができる。よって、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。
これにより、係合部４Ａを切り欠きからなる係合凹部４ｂとすることで、係合部４Ａを簡易に構成することができる。また、後方カバー部材５の腕部５ｂが係合凹部４ｂの上下の内壁に当接するように係合する構成とすることで、前方カバー部材４と後方カバー部材５とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材４と後方カバー部材５とを十分な保持力で係合することができる、という効果を奏する。 Accordingly, the base portion 5a of the rear cover member covers the rear side of the case 3, that is, there is no portion where the rear cover member is divided on the rear side of the case 3, and the two arm portions 5b are connected to the front cover member. To be integrated with each other. Thereby, since the part where the rear cover member is divided by being pressed does not spread, the pressing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.
Thereby, 4 A of engaging parts can be simply comprised by making the engaging part 4A into the engaging recessed part 4b which consists of notches. In addition, the front cover member 4 and the rear cover member 5 are engaged with each other with a sufficient holding force by engaging the arm portion 5b of the rear cover member 5 so as to contact the upper and lower inner walls of the engagement recess 4b. Can be combined. Therefore, the front cover member 4 and the rear cover member 5 can be engaged with each other with a sufficient holding force with a simple configuration.

また、本実施形態のプッシュスイッチ１００では、前方カバー部材４の係合凹部４ｂの上下方向で対向する面部４ｃ同士の間隔は、幅方向外方側に向うにしたがって狭くなるように形成されており、後方カバー部材５の腕部５ｂは、先端が上下方向に２股に分割された係合端部５ｃとなっており、係合端部５ｃは係合凹部４ｂに挿入されて、係合凹部４ｂの上下方向で対向する面部４ｃと当接するように押し広げられて係合されている、構成とした。 Moreover, in the push switch 100 of this embodiment, the space | interval of the surface parts 4c which oppose the up-down direction of the engaging recessed part 4b of the front cover member 4 is formed so that it may become narrow toward the width direction outward side. The arm portion 5b of the rear cover member 5 is an engagement end portion 5c whose tip is divided into two forks in the vertical direction, and the engagement end portion 5c is inserted into the engagement recess portion 4b, It is configured to be expanded and engaged so as to come into contact with the surface portion 4c opposed in the vertical direction of 4b.

これにより、係合凹部４ｂの上下方向で対向する面部４ｃ同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成され、先端が上下方向に２股に分割された係合端部５ｃが係合凹部４ｂに挿入され、係合端部５ｃを係合凹部４ｂの上下方向で対向する面部４ｃと当接するように押し広げて、前方カバー部材４と後方カバー部材５とが係合される構成とした。係合端部５ｃを上下方向に押し広げて、前方カバー部材４と後方カバー部材５と係合させると、係合凹部４ｂの上下方向で対向する面部４ｃ同士の間隔が広い側の係合端部５ｃは、係合凹部４ｂの上下方向で対向する面部４ｃ同士の間隔が狭い側の係合端部５ｃよりも広くなるように広げられる。これにより、図１３に示すように係合端部５ｃは、それぞれ捻じられた様にひろげられ、係合端部５ｃと係合凹部４ｂとの係合はより強固となり、押圧方向には外れにくくなる。また、係合凹部４ｂの上下方向で対向する面部４ｃ同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成されているため、幅方向外方側に対しても係合は外れにくくなっている。したがって、基板取り付け後に前方側からの押圧操作に対してより耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 Thus, the engagement end is formed such that the interval between the surface portions 4c opposed to each other in the vertical direction of the engagement recess 4b becomes narrower toward the outer side in the width direction, and the tip is divided into two forks in the vertical direction. The portion 5c is inserted into the engagement recess 4b, and the engagement end portion 5c is expanded so as to contact the surface portion 4c opposed to the engagement recess 4b in the vertical direction, so that the front cover member 4 and the rear cover member 5 are engaged. The composition was combined. When the engagement end portion 5c is pushed up and down and engaged with the front cover member 4 and the rear cover member 5, the engagement end on the side where the interval between the surface portions 4c facing each other in the vertical direction of the engagement recess 4b is wide. The part 5c is widened so as to be wider than the engagement end part 5c on the side where the distance between the face parts 4c facing each other in the vertical direction of the engagement concave part 4b is narrow. As a result, as shown in FIG. 13, the engagement end portions 5c are expanded as if they were twisted, and the engagement between the engagement end portions 5c and the engagement recesses 4b becomes stronger and is less likely to come off in the pressing direction. Become. Moreover, since the space | interval of the surface parts 4c which oppose the up-down direction of the engagement recessed part 4b is formed so that it may become narrow as it goes to the width direction outer side, engagement is also performed to the width direction outer side. It is hard to come off. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached.

また、本実施形態のプッシュスイッチ１００では、前方カバー部材４には、第１半田付け部４ｄが設けられ、後方カバー部材５には、第２半田付け部５ｄが設けられ、第１半田付け部４ｄと第２半田付け部５ｄとは、僅かな隙間Ｄを有して隣り合って配置されている、構成とした。 In the push switch 100 according to the present embodiment, the front cover member 4 is provided with a first soldering portion 4d, and the rear cover member 5 is provided with a second soldering portion 5d. 4d and the 2nd soldering part 5d were set as the structure arrange | positioned adjacent to each other with a slight gap D.

これにより、第１半田付け部４ｄと第２半田付け部５ｄとを設けるとともに、第１半田付け部４ｄと第２半田付け部５ｄとが僅かな隙間Ｄを有して隣り合って配置されることで、第１半田付け部４ｄと第２半田付け部５ｄとを半田付けした際に、前方カバー部材４と後方カバー部材５とは半田により連結される。そのため、操作部材１を強い力で押圧された場合にも、係合端部５ｃと係合凹部４ｂとの係合箇所にかかる負荷が半田により連結された部分に分散されるため、係合端部５ｃと係合凹部４ｂとの係合は外れにくくなる。したがって、基板取り付け後に前方側からの押圧操作に対してさらに耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。例えば、図３に記載の基板ＣＢ１にプッシュスイッチ１００がマウントされると、第１半田付け部４ｄと第２半田付け部５ｄとは同じランドＬＮ１上に配置される。このようなランドＬＮ１上に第１半田付け部４ｄおよび第２半田付け部５ｄを半田付けすると、ランドＬＮ１を伝わって半田が繋がり、前方カバー部材４と後方カバー部材５とは半田により連結される。 Thus, the first soldering part 4d and the second soldering part 5d are provided, and the first soldering part 4d and the second soldering part 5d are arranged adjacent to each other with a slight gap D. Thus, when the first soldering portion 4d and the second soldering portion 5d are soldered, the front cover member 4 and the rear cover member 5 are connected by solder. For this reason, even when the operation member 1 is pressed with a strong force, the load applied to the engagement portion between the engagement end portion 5c and the engagement recess portion 4b is distributed to the portion connected by the solder. The engagement between the portion 5c and the engagement recess 4b is difficult to disengage. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached. For example, when the push switch 100 is mounted on the substrate CB1 illustrated in FIG. 3, the first soldering portion 4d and the second soldering portion 5d are disposed on the same land LN1. When the first soldering portion 4d and the second soldering portion 5d are soldered on the land LN1, the solder is connected through the land LN1, and the front cover member 4 and the rear cover member 5 are connected by solder. .

また、本実施形態のプッシュスイッチ１００では、ケース３の、第１半田付け部４ｄおよび第２半田付け部５ｄと対向する箇所には、凹形状に形成された第１逃げ部３ｃが設けられ、ケース３の下面には、幅方向に溝状に延設された第２逃げ部３ｄが設けられている、構成とした。 Further, in the push switch 100 of the present embodiment, the case 3 is provided with a first relief portion 3c formed in a concave shape at a location facing the first soldering portion 4d and the second soldering portion 5d, The lower surface of the case 3 is provided with a second relief portion 3d extending in a groove shape in the width direction.

これにより、第１逃げ部３ｃおよび第２逃げ部３ｄを設けることで、プッシュスイッチを基板に半田付けする際に発生するフラックスが、第１逃げ部３ｃおよび第２逃げ部３ｄを伝わるため、フラックスがケース３の空間部３ｂに到達するまでの距離を長くしたり、フラックスを空間部３ｂとは異なる方向へ誘導することができる。よって、空間部３ｂ内にフラックスが入り込みにくくなり、フラックスの付着による可動接点部材２と固定接点部３ａとの導通不良の発生を少なくすることができる。したがって、安定したスイッチングができるプッシュスイッチを提供することができる、という効果を奏する。 Thus, by providing the first escape portion 3c and the second escape portion 3d, the flux generated when the push switch is soldered to the substrate is transmitted to the first escape portion 3c and the second escape portion 3d. The distance until the space 3b reaches the space 3b of the case 3 can be increased, or the flux can be guided in a direction different from the space 3b. Therefore, it becomes difficult for flux to enter the space 3b, and the occurrence of poor conduction between the movable contact member 2 and the fixed contact 3a due to adhesion of the flux can be reduced. Therefore, it is possible to provide a push switch capable of stable switching.

また、第１逃げ部３ｃに対向する第１半田付け部４ｄおよび第２半田付け部５ｄの面には、半田付けした際にフィレットが形成されるため、第１半田付け部４ｄおよび第２半田付け部５ｄは両側にフィレットが形成され、プッシュスイッチ１００は基板に対してより強固に保持される。 In addition, since fillets are formed on the surfaces of the first soldering portion 4d and the second soldering portion 5d facing the first relief portion 3c when soldering, the first soldering portion 4d and the second soldering portion are formed. The attaching part 5d is formed with fillets on both sides, and the push switch 100 is held more firmly against the substrate.

また、本実施形態のプッシュスイッチでは、ケース３の後方側に位置する、後方カバー部材５の基部５ａから下方へ延出して第３半田付け部５ｆを有する構成とした。 Further, the push switch of the present embodiment is configured to have a third soldering portion 5f extending downward from the base portion 5a of the rear cover member 5 located on the rear side of the case 3.

次にプッシュスイッチ２００の構造について図２２および図２８を用いて説明する。図２８は図１７（ｂ）に示す断面Ｆ−Ｆを示す模式断面図である。なお、説明を容易にするため、第２固定接点部２４ｇの位置は実際の位置とは異なる。 Next, the structure of the push switch 200 will be described with reference to FIGS. FIG. 28 is a schematic sectional view showing a section FF shown in FIG. For ease of explanation, the position of the second fixed contact portion 24g is different from the actual position.

図２８に示すように、可動接点部材２２は第２ケース部材２４の第２空間部２４ｂ内に収容される。可動接点部材２２は可動接点部２２ａが前方（Ｘ１方向）へ突出する向きに配置され、一方（図２３に示すＺ２方向側）の常接接点部２２ｃは第２空間部２４ｂの最奥面２４ｅに露出する第２固定接点部２４ｇの接触部２４ｈ（図１９参照）と接触し、他方の常接接点部２２ｃは、最奥面２４ｅの第１固定接点部２４ｆを挟んで第２固定接点部２４ｇに対向する位置に周辺接触部２４ｑと同じ高さとなるように突出している箇所（図１９参照）に接触している。なお、可動接点部２２ａは第１固定接点部２４ｆとは離間している。シート部材２９は、粘着面２９ａが第２空間部２４ｂに対向する向きで、可動接点部材２２が配置された第２空間部２４ｂを覆うように配置される。シート部材２９は粘着面２９ａの粘着力により第２ケース部材２４の第２対向面２４ｄに保持されるとともに、可動接点部材２２を第２空間部２４ｂ内に保持して、可動接点部材２２と第２固定接点部２４ｇとは常時接触される。シート部材２９は屈曲性を有しているため、シート部材２９を介して押圧された場合には、可動接点部材２２の可動接点部２２ａは第２空間部２４ｂ内でも可動可能で、かつ中央接触部２４ｎ（図１９参照）と接触可能な位置に保持されている。操作部材２１は、ボタン部２１ｃを第１空間部２５ａ側から開口部２５ｅに挿通した状態で、第１ケース部材２５の第１空間部２５ａ内に保持される。なお、操作部材２１は、その一部（突出部２１ａ（図２４参照））が突出形状部２５ｄ（図２１参照）に配置されるとともに案内され、第１空間部２５ａ内をスライド移動可能に保持されている。第１空間部２５ａ内に操作部材２１を保持した第１ケース部材２５は、操作部材２１のアクチュエータ部２１ｂがシート部材２９と対向する向きで、第２ケース部材２４と係合する。すなわち、第１対向面２５ｃと第２対向面２４ｄとでシート部材２９を挟み込み、第１空間部２５ａと第２空間部２４ｂとが、操作部材２１及び可動接点部材２２を収容する空間部２３ａを形成するように係合する。このように第１ケース部材２５と第２ケース部材２４とを係合することで、操作部材２１のアクチュエータ部２１ｂと可動接点部材２２の可動接点部２２ａとはシート部材２９を介して接触する。また、前方カバー部材２７は、操作部材２１のボタン部２１ｃが貫通穴２７ａから突出した状態で、空間部２３ａを覆うように第１ケース部材２５と係合している。また、後方カバー部材２８は、基部２８ａでケース２３（第２ケース部材２４）の後方側を覆うとともに、腕部２８ｂを前方に延出させた状態で第２ケース部材２４と係合している。また前方へ延出した腕部２８ｂが、前方カバー部材２７の係合部２７ｂにそれぞれ係合されて前方カバー部材２７と後方カバー部材２８とが一体化され、カバー部材２６が形成されている。なお、第２実施形態においては、係合部２７ｂと腕部２８ｂとの係合は、後方カバー部材２８の腕部２８ｂの先端部２８ｃが、前方カバー部材２７の係合穴部２７ｃに挿入され、前方カバー部材２７の前方側にて内方側に折り曲げられて係合することで行われている。このように、カバー部材２６（図２５参照）が形成されることで、第１ケース部材２５と第２ケース部材２４とは、シート部材２９を圧接挟持する。このようにして第２実施形態におけるプッシュスイッチ２００は構成される。プッシュスイッチ２００が形成されると、図２２に示すように、突出形状部２５ｄの一部と第２対向面２４ｄの一部とが対向するように配置されている。したがって、突出形状部２５ｄに沿って移動可能に配置される操作部材２１の突出部２１ａは、第２対向面２４ｄに接触可能な位置に配置されている。ただし、操作部材２１を介して可動接点部材２２を押圧し、可動接点部２２ａを固定接点部２４ａ（第１固定接点部２４ｆ）に接触させたときに、突出部２１ａは第２対向面２４ｄから離間している。また、第２開口２４ｃの外形形状の長手辺と短手辺とが交差する箇所が突出形状部２５ｄに対応した箇所に配置されているため、操作部材２１の突出部２１ａは、第２開口２４ｃの外形形状の長手辺と短手辺とが交差する箇所で、第２対向面２４ｄに接触可能な位置に配置されている。また、第２ケース部材２４の第２対向面２４ｄにおいて、操作部材２１の突出部２１ａが当接可能な位置は、横方向における第２固定接点部２４ｇの接触部２４ｈの外方側に位置している。なお、図２２においては、シート部材２９を図示していないが、実際には、第１ケース部材２５の第１対向面２５ｃと第２ケース部材２４の第２対向面２４ｄとの間にはシート部材２９が挟まれている。 As shown in FIG. 28, the movable contact member 22 is accommodated in the second space 24 b of the second case member 24. The movable contact member 22 is disposed in a direction in which the movable contact portion 22a protrudes forward (X1 direction), and the permanent contact portion 22c (on the Z2 direction side shown in FIG. 23) is the innermost surface 24e of the second space portion 24b. The second fixed contact portion 24g is in contact with the contact portion 24h (see FIG. 19) of the second fixed contact portion 24g exposed on the other side, and the other permanent contact portion 22c sandwiches the first fixed contact portion 24f on the innermost surface 24e. It is in contact with a location (see FIG. 19) that protrudes so as to be at the same height as the peripheral contact portion 24q at a position facing 24g. The movable contact portion 22a is separated from the first fixed contact portion 24f. The sheet member 29 is disposed so as to cover the second space portion 24b where the movable contact member 22 is disposed, with the adhesive surface 29a facing the second space portion 24b. The sheet member 29 is held on the second facing surface 24d of the second case member 24 by the adhesive force of the adhesive surface 29a, and the movable contact member 22 is held in the second space portion 24b, so that the movable contact member 22 and the second contact surface 22 2 is always in contact with the fixed contact portion 24g. Since the sheet member 29 has flexibility, when the sheet member 29 is pressed through the sheet member 29, the movable contact portion 22a of the movable contact member 22 is movable in the second space portion 24b and is in the center contact. The portion 24n (see FIG. 19) is held at a position where it can come into contact. The operation member 21 is held in the first space portion 25a of the first case member 25 in a state where the button portion 21c is inserted into the opening portion 25e from the first space portion 25a side. Note that a part of the operation member 21 (protruding portion 21a (see FIG. 24)) is arranged and guided in the protruding shape portion 25d (see FIG. 21), and is slidably held in the first space portion 25a. Has been. The first case member 25 holding the operation member 21 in the first space portion 25 a engages with the second case member 24 in a direction in which the actuator portion 21 b of the operation member 21 faces the sheet member 29. That is, the sheet member 29 is sandwiched between the first facing surface 25c and the second facing surface 24d, and the first space portion 25a and the second space portion 24b define the space portion 23a that houses the operation member 21 and the movable contact member 22. Engage to form. Thus, by engaging the first case member 25 and the second case member 24, the actuator portion 21 b of the operation member 21 and the movable contact portion 22 a of the movable contact member 22 are brought into contact with each other via the sheet member 29. Further, the front cover member 27 is engaged with the first case member 25 so as to cover the space portion 23a in a state where the button portion 21c of the operation member 21 protrudes from the through hole 27a. Further, the rear cover member 28 covers the rear side of the case 23 (second case member 24) with the base portion 28a, and is engaged with the second case member 24 with the arm portion 28b extending forward. . Further, the arm portion 28 b extending forward is engaged with the engaging portion 27 b of the front cover member 27, and the front cover member 27 and the rear cover member 28 are integrated to form the cover member 26. In the second embodiment, the engagement between the engagement portion 27 b and the arm portion 28 b is such that the tip end portion 28 c of the arm portion 28 b of the rear cover member 28 is inserted into the engagement hole portion 27 c of the front cover member 27. The front cover member 27 is bent and engaged inward on the front side. Thus, by forming the cover member 26 (see FIG. 25), the first case member 25 and the second case member 24 press and sandwich the sheet member 29. In this way, the push switch 200 in the second embodiment is configured. When the push switch 200 is formed, as shown in FIG. 22, a part of the projecting shape part 25d and a part of the second facing surface 24d are arranged to face each other. Therefore, the protruding portion 21a of the operating member 21 that is movably disposed along the protruding shape portion 25d is disposed at a position that can contact the second facing surface 24d. However, when the movable contact member 22 is pressed via the operation member 21 and the movable contact portion 22a is brought into contact with the fixed contact portion 24a (first fixed contact portion 24f), the protruding portion 21a extends from the second facing surface 24d. It is separated. In addition, since the portion where the long side and the short side of the outer shape of the second opening 24c intersect is disposed at a position corresponding to the protruding shape portion 25d, the protruding portion 21a of the operation member 21 is provided with the second opening 24c. The outer shape is disposed at a position where the long side and the short side of the outer shape can contact the second facing surface 24d. Further, on the second facing surface 24d of the second case member 24, the position where the protruding portion 21a of the operation member 21 can abut is located on the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction. ing. Although the sheet member 29 is not illustrated in FIG. 22, the sheet is actually between the first facing surface 25 c of the first case member 25 and the second facing surface 24 d of the second case member 24. The member 29 is sandwiched.

次にプッシュスイッチ２００の動作について図２８ないし図３０を用いて説明する。図２９は図２８に示す状態から押圧操作された後の状態を示す模式断面図である。図３０は第２実施形態におけるプッシュスイッチ２００がオーバーストロークになった状態を示す模式断面図である。 Next, the operation of the push switch 200 will be described with reference to FIGS. 29 is a schematic cross-sectional view showing a state after a pressing operation is performed from the state shown in FIG. FIG. 30 is a schematic cross-sectional view showing a state where the push switch 200 according to the second embodiment has an overstroke.

図２８に示す状態は、プッシュスイッチ２００が操作されていない初期状態を示している。図２８に示す状態においては、常接接点部２２ｃは第２固定接点部２４ｇと接触しているが、可動接点部２２ａは第１固定接点部２４ｆとは離間している。つまり、図２８に示す状態は、第１固定接点部２４ｆと第２固定接点部２４ｇとの電気的な導通は無い状態である。図２８に示す状態から、図２９に示すように、操作部材２１を後方側（Ｘ２方向）へ押圧すると、シート部材２９を介して可動接点部２２ａに接触するアクチュエータ部２１ｂは可動接点部２２ａを後方側へ押圧する。押圧された可動接点部２２ａは後方側へ撓んだ後に反転し、第１固定接点部２４ｆに接触する。可動接点部２２ａと第１固定接点部２４ｆとが接触することで、第１固定接点部２４ｆと第２固定接点部２４ｇとは、可動接点部材２２を介して電気的に導通される。また、操作部材２１への押圧を解除すると、可動接点部２２ａの弾性力により、図２８に示す初期状態に復帰し、第１固定接点部２４ｆと第２固定接点部２４ｇとの電気的な導通は無い状態となる。このように、可動接点部材２２と第１固定接点部２４ｆとが接離し、第１固定接点部２４ｆと第２固定接点部２４ｇとの電気的な導通状態を切り替えることで入力を行なうことができ、外部と電気的に接続可能な外部接続端子２４ｒを介して入力信号として出力され、プッシュスイッチとして機能する。また、可動接点部２２ａと第１固定接点部２４ｆとが接触するとき、操作部材２１の鍔部２１ｄ（突出部２１ａ（図２４参照））と第２ケース部材２４の第２対向面２４ｄとは離間している。しかし、操作者により操作部材２１を必要以上の力で押し込み操作された場合や、プッシュスイッチ２００が取り付けられた電子機器などを誤って落下させ、操作部材２１を押圧する方向に衝撃が加わった場合など、可動接点部２２ａと第１固定接点部２４ｆとが接触したあとにオーバーストロークになる場合もある。このようなオーバーストロークとなった場合には、図３０に示すように、操作部材２１のアクチュエータ部２１ｂが潰れるとともに、突出部２１ａ（図２４参照）が第２ケース部材２４の第２対向面２４ｄに接触し、操作部材２１がさらに後方へ押し込まれるのを阻止する。なお、図３０においては、アクチュエータ部２１ｂがほとんどなくなるまで潰れるように図示しているが、実際には、アクチュエータ部２１ｂの先端部が潰れる程度であり、アクチュエータ部２１ｂの先端部が潰れた後であっても、プッシュスイッチ２００への入力操作は可能である。 The state shown in FIG. 28 shows an initial state where the push switch 200 is not operated. In the state shown in FIG. 28, the normal contact portion 22c is in contact with the second fixed contact portion 24g, but the movable contact portion 22a is separated from the first fixed contact portion 24f. That is, the state shown in FIG. 28 is a state where there is no electrical continuity between the first fixed contact portion 24f and the second fixed contact portion 24g. From the state shown in FIG. 28, as shown in FIG. 29, when the operating member 21 is pressed backward (X2 direction), the actuator portion 21b that contacts the movable contact portion 22a via the sheet member 29 moves the movable contact portion 22a. Press backwards. The pressed movable contact portion 22a is inverted after being bent backward, and comes into contact with the first fixed contact portion 24f. When the movable contact portion 22a and the first fixed contact portion 24f come into contact with each other, the first fixed contact portion 24f and the second fixed contact portion 24g are electrically connected via the movable contact member 22. Further, when the pressing on the operation member 21 is released, the initial state shown in FIG. 28 is restored by the elastic force of the movable contact portion 22a, and the electrical continuity between the first fixed contact portion 24f and the second fixed contact portion 24g. There will be no state. As described above, the movable contact member 22 and the first fixed contact portion 24f are brought into contact with and separated from each other, and the input can be performed by switching the electrical conduction state between the first fixed contact portion 24f and the second fixed contact portion 24g. It is output as an input signal via an external connection terminal 24r that can be electrically connected to the outside, and functions as a push switch. Further, when the movable contact portion 22a and the first fixed contact portion 24f come into contact with each other, the flange portion 21d (projecting portion 21a (see FIG. 24)) of the operation member 21 and the second facing surface 24d of the second case member 24 are It is separated. However, when the operation member 21 is pushed in with an excessive force by the operator, or when an electronic device or the like to which the push switch 200 is attached is accidentally dropped and an impact is applied in the direction in which the operation member 21 is pressed. For example, an overstroke may occur after the movable contact portion 22a and the first fixed contact portion 24f come into contact with each other. In such an overstroke, as shown in FIG. 30, the actuator portion 21 b of the operation member 21 is crushed and the protruding portion 21 a (see FIG. 24) is the second facing surface 24 d of the second case member 24. This prevents the operation member 21 from being pushed further backward. In FIG. 30, the actuator portion 21b is shown to be crushed until it almost disappears, but in reality, the tip portion of the actuator portion 21b is crushed, and after the tip portion of the actuator portion 21b is crushed. Even if it exists, the input operation to the push switch 200 is possible.

以下、本実施形態としたことによる効果について説明する。なお、一部の効果の説明には図１６または図３１を用いて説明する。図３１は図１５に記載のＧ部を拡大して示す拡大図である。 Hereinafter, the effect by having set it as this embodiment is demonstrated. Some effects will be described with reference to FIG. 16 or FIG. FIG. 31 is an enlarged view showing a G portion shown in FIG.

A rear cover member 28 including a case 23, a front cover member 27 covering the space portion 23a, a base portion 28a covering the rear side of the case 23, and arm portions 28b extending from both ends of the base portion 28a to the front side. In the push switch having the above, the front cover member 27 is provided with a through hole 27a from which the operation member 21 protrudes, and an engagement portion 27b to be engaged with the arm portion 28b of the rear cover member 28 at both ends. The arm portion 28b of the rear cover member 28 is engaged with the engaging portion 27b of the front cover member 27, respectively, so that the front cover member 27 and the rear cover member 28 are engaged. There are integrated, it has a structure.

これにより、後方カバー部材２８の基部２８ａがケース２３の後方側を覆う、すなわちケース２３の後方側には後方カバー部材２８が分断された箇所が無いとともに、２つの腕部２８ｂを前方カバー部材２７と係合させて一体化させる構成とした。これにより、押圧されたときに、選考技術のように後方カバー部材２８の分断された箇所が広がることはないので、先行技術に比べて前方側からの押し込み強度を向上させることができる。よって、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 Accordingly, the base portion 28a of the rear cover member 28 covers the rear side of the case 23, that is, there is no portion where the rear cover member 28 is divided on the rear side of the case 23, and the two arm portions 28b are connected to the front cover member 27. To be integrated with each other. Thereby, since the part where the rear cover member 28 was divided does not spread like the selection technique when pressed, the pushing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.

また、本実施形態のプッシュスイッチ２００では、係合部２７ｂが貫通孔からなる係合穴部２７ｃであり、後方カバー部材２８の腕部２８ｂが係合穴部２７ｃに挿入され、前方カバー部材２７の前方側にて内方側に折り曲げられて係合している、構成とした。 Further, in the push switch 200 of the present embodiment, the engaging portion 27b is an engaging hole portion 27c formed of a through hole, and the arm portion 28b of the rear cover member 28 is inserted into the engaging hole portion 27c, so that the front cover member 27 is inserted. It is set as the structure which is bend | folded and engaged in the inward side in the front side.

これにより、係合部２７ｂを貫通孔からなる係合穴部２７ｃとすることで、係合部２７ｂを簡易に構成することができる。また、後方カバー部材２８の腕部２８ｂが係合穴部２７ｃに挿入され、折り曲げることで係合する構成とすることで、前方カバー部材２７と後方カバー部材２８とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材２７と後方カバー部材２８とを十分な保持力で係合することができる、という効果を奏する。 Thereby, the engaging part 27b can be simply comprised by making the engaging part 27b into the engaging hole part 27c which consists of a through-hole. In addition, the arm portion 28b of the rear cover member 28 is inserted into the engagement hole portion 27c and engaged by being bent, so that the front cover member 27 and the rear cover member 28 are engaged with a sufficient holding force. can do. Therefore, the front cover member 27 and the rear cover member 28 can be engaged with each other with a sufficient holding force with a simple configuration.

また、本実施形態のプッシュスイッチ２００では、前方カバー部材２７の係合穴部２７ｃの開口形状は幅方向における外方側が円弧形状となっており、後方カバー部材２８の腕部２８ｂの先端部２８ｃは係合穴部２７ｃに挿入可能に形成されており、係合穴部２７ｃに挿入されて、内方側に折り曲げられて係合されている、構成とした。 Further, in the push switch 200 of the present embodiment, the opening shape of the engagement hole portion 27c of the front cover member 27 has an arc shape on the outer side in the width direction, and the distal end portion 28c of the arm portion 28b of the rear cover member 28. Is formed so as to be insertable into the engagement hole 27c, and is inserted into the engagement hole 27c, bent inward and engaged.

これにより、係合穴部２７ｃの開口形状を、幅方向における外方側が円弧形状とすることで、幅方向における外方側においては上下方向の寸法が内方側よりも小さくなる。係合穴部２７ｃと腕部２８ｂとを係合するために、腕部２８ｂの先端部２８ｃを内方側に折り曲げたときに、腕部２８ｂが係合穴部２７ｃの幅方向における外方側へ広がりやすい。仮に広がったとしても、図３１に破線で示すように、腕部２８ｂが係合穴部２７ｃの幅方向における外方側（図３１においてはＹ１方向側）の円弧形状の面に接触し、外方側へ広がることなく、腕部２８ｂは内方側へ寄せられる。したがって、前方カバー部材２７と後方カバー部材２８とをガタのない状態で固定することができ、外れにくい強固な係合とすることができる、という効果を奏する。 Thereby, the dimension of the up-down direction is smaller on the outer side in the width direction than on the inner side by setting the opening shape of the engagement hole portion 27c to an arc shape on the outer side in the width direction. When the distal end portion 28c of the arm portion 28b is bent inward to engage the engagement hole portion 27c with the arm portion 28b, the arm portion 28b is located outward in the width direction of the engagement hole portion 27c. Easy to spread. Even if it spreads, as shown by a broken line in FIG. 31, the arm portion 28b contacts the arc-shaped surface on the outer side in the width direction of the engagement hole portion 27c (the Y1 direction side in FIG. 31) The arm portion 28b is moved toward the inner side without spreading toward the inner side. Therefore, it is possible to fix the front cover member 27 and the rear cover member 28 without any backlash and to achieve a strong engagement that is difficult to come off.

また、本実施形態のプッシュスイッチ２００では、固定接点部２４ａを有し、可動接点部材２２を収容する第２空間部２４ｂを備える第２ケース部材２４と、第２ケース部材２４と係合して、操作部材２１を案内するようにその一部を収容する第１空間部２５ａを備える第１ケース部材２５と、からなるプッシュスイッチにおいて、第２ケース部材２４は第２空間部２４ｂが開口した第２開口２４ｃのある第２対向面２４ｄを有し、第１ケース部材２５は第１空間部２５ａが開口した第１開口２５ｂのある第１対向面２５ｃを有し、第２ケース部材２４と第１ケース部材２５とは、第２対向面２４ｄと第１対向面２５ｃとを対向させて係合され、第１開口２５ｂの外形形状を第２開口２４ｃの外形形状に重ねたとき、第１開口２５ｂの外形形状は第２開口２４ｃの外形形状からはみ出す突出形状部２５ｄを有し、操作部材２１は第１開口２５ｂの外形形状に沿うように形成されて、突出形状部２５ｄに配置される突出部２１ａを有し、操作部材２１を介して可動接点部材２２を固定接点部２４ａに接触させたときに、突出部２１ａは第２対向面２４ｄから離間している、構成とした。 Further, in the push switch 200 of the present embodiment, the second case member 24 having the fixed contact portion 24 a and having the second space portion 24 b for accommodating the movable contact member 22 is engaged with the second case member 24. In the push switch comprising the first case member 25 including the first space portion 25a that accommodates a part of the operation member 21 so as to guide the operation member 21, the second case member 24 has the second space portion 24b opened. The first case member 25 has a first facing surface 25c with a first opening 25b in which the first space 25a is opened, and the second case member 24 and the second case member 24 have a second facing surface 24d with two openings 24c. The first case member 25 is engaged with the second facing surface 24d and the first facing surface 25c facing each other. When the outer shape of the first opening 25b is overlapped with the outer shape of the second opening 24c, the first opening is formed. 25b external shape Has a protruding portion 25d that protrudes from the outer shape of the second opening 24c, and the operating member 21 has a protruding portion 21a that is formed along the outer shape of the first opening 25b and is disposed in the protruding shape portion 25d. When the movable contact member 22 is brought into contact with the fixed contact portion 24a via the operation member 21, the protruding portion 21a is separated from the second facing surface 24d.

これにより、第１開口２５ｂの外形形状を第２開口２４ｃの外形形状に重ねたとき、第１開口２５ｂの外形形状は第２開口２４ｃの外形形状からはみ出すように形成された突出形状部２５ｄを有し、操作部材２１は第１開口２５ｂの外形形状に沿うように形成されており、突出形状部２５ｄに配置される突出部２１ａを有する構成とした。したがって、誤って操作部材２１が無理押しされるなど、オーバーストロークとなったときに、操作部材２１の突出部２１ａを第２対向面２４ｄに当接させることでストッパを構成して、過剰な押し込み時の耐性を向上させることができる。このような構造であれば、押圧操作された方向に可動接点部材２２が配置された構造であっても、過剰なオーバーストロークを止めることができる。したがって、押圧操作された方向に可動接点部材２２が配置され、過剰な押し込みに対応可能なプッシュスイッチを提供することができる、という効果を奏する。 As a result, when the outer shape of the first opening 25b is overlapped with the outer shape of the second opening 24c, the outer shape of the first opening 25b is changed from the protruding shape portion 25d formed so as to protrude from the outer shape of the second opening 24c. The operation member 21 is formed so as to follow the outer shape of the first opening 25b, and has a protruding portion 21a disposed on the protruding shape portion 25d. Therefore, when the operation member 21 is accidentally pushed by force, for example, when an overstroke occurs, a stopper is formed by bringing the protruding portion 21a of the operation member 21 into contact with the second facing surface 24d, and excessive push-in is performed. Time tolerance can be improved. With such a structure, an excessive overstroke can be stopped even if the movable contact member 22 is arranged in the direction in which the pressing operation is performed. Therefore, there is an effect that the movable contact member 22 is arranged in the direction in which the pressing operation is performed, and a push switch that can cope with excessive pressing can be provided.

また、本実施形態のプッシュスイッチ２００では、第２開口２４ｃの外形形状は、長手辺が直線形状で、短手辺が円弧形状の長方形状であり、可動接点部材２２は第２開口２４ｃの外形形状に沿うように形成され、操作部材２１の突出部２１ａは、第２開口２４ｃの外形形状の長手辺と短手辺とが交差する箇所で、第２対向面２４ｄに接触可能に形成されている、構成とした。 Further, in the push switch 200 of the present embodiment, the outer shape of the second opening 24c is a rectangular shape having a long side of a straight line and a short side of an arc, and the movable contact member 22 has an outer shape of the second opening 24c. The protruding portion 21a of the operation member 21 is formed so as to be in contact with the second facing surface 24d at a location where the long side and the short side of the outer shape of the second opening 24c intersect. It was configured.

これにより、第２開口２４ｃの外形形状を、長手辺が直線形状で、短手辺が円弧形状の長方形状とし、短手辺と長手辺とが交差する位置で突出部２１ａが第２対向面２４ｄに接触可能とすることで、仮にオーバーストロークになった場合に、突出部２１ａと第２対向面２４ｄとの接触面積を大きくすることができる。すなわち、より大きな荷重が加わった場合にも、破損することなく操作部材２１の移動を止めることができる。したがって、押圧操作された方向に可動接点部材２２が配置され、過剰な押し込みに対応可能なプッシュスイッチを提供することができる、という効果を奏する。 As a result, the outer shape of the second opening 24c is a rectangular shape having a long side having a linear shape and a short side having an arc shape, and the projecting portion 21a has a second opposing surface at a position where the short side and the long side intersect. By making the contact with 24d possible, the contact area between the protruding portion 21a and the second facing surface 24d can be increased if an overstroke occurs. That is, even when a larger load is applied, the movement of the operation member 21 can be stopped without being damaged. Therefore, there is an effect that the movable contact member 22 is arranged in the direction in which the pressing operation is performed, and a push switch that can cope with excessive pressing can be provided.

また、本実施形態のプッシュスイッチ２００では、可動接点部材２２は、ばね性を有する金属板から形成されており、操作部材２１は、可動接点部材２２を押圧するための合成樹脂材からなるアクチュエータ部２１ｂを有し、アクチュエータ部２１ｂは、可動接点部材２２を撓ませることが可能で、かつ第２ケース部材２４を破損させない所定の荷重が加わったときに潰れる、構成とした。 Further, in the push switch 200 of the present embodiment, the movable contact member 22 is formed from a metal plate having a spring property, and the operation member 21 is an actuator portion made of a synthetic resin material for pressing the movable contact member 22. The actuator portion 21b is configured to be able to bend the movable contact member 22 and to be crushed when a predetermined load that does not damage the second case member 24 is applied.

これにより、可動接点部材２２を撓ませることが可能で、かつ第２ケース部材２４を破損させない所定の荷重が加わったときに、アクチュエータ部２１ｂが潰れる構成としたことで、仮にオーバーストロークになった場合には、先ず、アクチュエータ部２１ｂが潰れ、そのあとに突出部２１ａと第２対向面２４ｄとが当接することになる。そのため、第２ケース部材２４に過剰な押圧付加が加わることによる、固定接点部２４ａの周辺の破損を軽減することができる。また、アクチュエータ部２１ｂは、オーバーストロークの移動量分であるわずかな量しか潰れないので、スイッチ機能が完全に喪失することは無い。したがって、押圧操作された方向に可動接点部材２２が配置され、過剰な押し込みに対応可能なプッシュスイッチを提供することができる、という効果を奏する。 Accordingly, the movable contact member 22 can be bent and the actuator portion 21b is crushed when a predetermined load that does not damage the second case member 24 is applied. In this case, the actuator portion 21b is first crushed, and then the protruding portion 21a and the second facing surface 24d come into contact with each other. Therefore, damage around the fixed contact portion 24a due to excessive pressing applied to the second case member 24 can be reduced. Further, since the actuator portion 21b can be crushed by a small amount corresponding to the amount of movement of the overstroke, the switch function is not completely lost. Therefore, there is an effect that the movable contact member 22 is arranged in the direction in which the pressing operation is performed, and a push switch that can cope with excessive pressing can be provided.

また、本実施形態のプッシュスイッチ２００では、固定接点部２４ａは、第２空間部２４ｂの第２開口２４ｃに対向する側の面である最奥面２４ｅに形成され、最奥面２４ｅの中央部分に形成される第１固定接点部２４ｆと、最奥面２４ｅにおいて第２空間部２４ｂの長手側の壁の近くに形成される第２固定接点部２４ｇと、からなり、第１固定接点部２４ｆおよび第２固定接点部２４ｇは、可動接点部材２２が接触する接触部２４ｈを有しており、第２ケース部材２４の第２対向面２４ｄにおいて、操作部材２１の突出部２１ａが当接可能な位置は、横方向における第２固定接点部２４ｇの接触部２４ｈの外方側に位置している、構成とした。 Further, in the push switch 200 of the present embodiment, the fixed contact portion 24a is formed on the innermost surface 24e that is a surface facing the second opening 24c of the second space portion 24b, and a central portion of the innermost surface 24e. The first fixed contact portion 24f formed on the innermost surface 24e and the second fixed contact portion 24g formed near the longitudinal wall of the second space portion 24b. The second fixed contact portion 24g has a contact portion 24h with which the movable contact member 22 contacts, and the protruding portion 21a of the operation member 21 can come into contact with the second facing surface 24d of the second case member 24. The position is set to be located on the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction.

これにより、横方向における第２固定接点部２４ｇの接触部２４ｈの外方側であれば、第２空間部２４ｂの最奥面２４ｅから固定接点部２４ａが露出する箇所がなくなるので、第２空間部２４ｂを設ける必要がなくなり、第２ケース部材２４の側壁を厚くすることができる。したがって、第２ケース部材２４の第２対向面２４ｄにおいて、操作部材２１の突出部２１ａが当接可能な位置を、横方向における第２固定接点部２４ｇの接触部２４ｈの外方側とすることで、突出部２１ａと第２対向面２４ｄとの接触面積を大きくすることができる。よって、より大きな荷重が加わった場合にも、破損することなく操作部材２１の移動を止めることができる、という効果を奏する。 Thereby, if it is on the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction, there is no place where the fixed contact portion 24a is exposed from the innermost surface 24e of the second space portion 24b. It is not necessary to provide the portion 24b, and the side wall of the second case member 24 can be thickened. Therefore, on the second facing surface 24d of the second case member 24, the position where the protruding portion 21a of the operation member 21 can come into contact is the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction. Thus, the contact area between the protruding portion 21a and the second facing surface 24d can be increased. Therefore, even when a larger load is applied, there is an effect that the movement of the operation member 21 can be stopped without being damaged.

また、本実施形態のプッシュスイッチ２００では、固定接点部２４ａを有し、操作部材２１及び可動接点部材２２を収容する空間部２３ａを備えるケース２３と、空間部２３ａを覆うカバー部材２６と、を備えたプッシュスイッチにおいて、固定接点部２４ａは空間部２３ａの一面である最奥面２４ｅに露出して形成されており、ケース２３は最奥面２４ｅの後方側に突出するように形成された本体部２４ｋを有し、本体部２４ｋには、後方側の端部から前方へ向かって一部切り欠かれた切り欠き部２４ｍを有し、固定接点部２４ａは、可動接点部材２２と接離する第１固定接点部２４ｆと、可動接点部材２２と常時接触する第２固定接点部２４ｇと、からなり、第１固定接点部２４ｆは、可動接点部材２２と接触する中央接触部２４ｎと、中央接触部２４ｎに連続して最奥面２４ｅから露出するとともに、中央接触部２４ｎの周囲へ延出された延出部２４ｐと、を有し、中央接触部２４ｎは、最奥面２４ｅの本体部２４ｋに対応した箇所に配置されている、構成とした。 Further, in the push switch 200 of the present embodiment, the case 23 having the fixed contact portion 24a and including the space portion 23a that houses the operation member 21 and the movable contact member 22, and the cover member 26 that covers the space portion 23a. In the provided push switch, the fixed contact portion 24a is formed so as to be exposed at the innermost surface 24e, which is one surface of the space portion 23a, and the case 23 is formed so as to protrude to the rear side of the innermost surface 24e. The main body portion 24k has a notch portion 24m partially cut away from the rear end portion toward the front, and the fixed contact portion 24a contacts and separates from the movable contact member 22. The first fixed contact portion 24f and the second fixed contact portion 24g that is always in contact with the movable contact member 22, and the first fixed contact portion 24f is a central contact portion 24n that is in contact with the movable contact member 22. The center contact portion 24n is exposed from the innermost surface 24e continuously to the center contact portion 24n, and has an extended portion 24p extending around the center contact portion 24n. The center contact portion 24n is a main body of the innermost surface 24e. It was set as the structure arrange | positioned in the location corresponding to the part 24k.

これにより、最奥面２４ｅの後方側で厚みのある本体部２４ｋに対応した箇所に中央接触部２４ｎを配置するとともに、中央接触部２４ｎの周囲に延出する延出部２４ｐを設けることで、押し込み操作されたときに、ケース２３に厚みのある部分で受け止めるとともに、受け止める面積を広げることができる。したがって、単位面積当たりで受け止める荷重を小さくするとともに、荷重に対して強い部分で受けることができる。よって、押し込み耐性の高いプッシュスイッチを提供することができる、という効果を奏する。 Thereby, while arrange | positioning the center contact part 24n in the location corresponding to the thick main-body part 24k on the back side of the innermost surface 24e, providing the extension part 24p extended around the center contact part 24n, When the push-in operation is performed, the case 23 can be received at a thick portion and the area to be received can be increased. Therefore, the load received per unit area can be reduced and received at a portion strong against the load. Therefore, it is possible to provide a push switch with high push resistance.

また、本実施形態のプッシュスイッチ２００では、第２固定接点部２４ｇの可動接点部材２２と接触する周辺接触部２４ｑは、最奥面２４ｅの切り欠き部２４ｍに対応した箇所に配置されている、構成とした。 Further, in the push switch 200 of the present embodiment, the peripheral contact portion 24q that contacts the movable contact member 22 of the second fixed contact portion 24g is disposed at a location corresponding to the notch portion 24m of the innermost surface 24e. The configuration.

これにより、周辺接触部２４ｑを切り欠き部２４ｍに対応した箇所に配置することで、本体部２４ｋに対応した箇所を、押し込み操作時に最も負荷がかかる中央接触部２４ｎおよび延出部２４ｐに、より大きな面積を確実に割り当てることが可能となる。したがって、より押し込み耐性の高いプッシュスイッチを提供することができる、という効果を奏する。 Thereby, by arranging the peripheral contact portion 24q at a location corresponding to the cutout portion 24m, the location corresponding to the main body portion 24k can be more concentrated on the central contact portion 24n and the extension portion 24p that are most loaded during the pushing operation. A large area can be reliably allocated. Therefore, it is possible to provide a push switch having higher push-in resistance.

また、本実施形態のプッシュスイッチ２００では、金属板からなりケース２３にインサート成型された回路部材３０は、一端に固定接点部２４ａを有するとともに、他端には、ケース２３の後方側から露出して外部と電気的に接続可能な外部接続端子２４ｒを有し、回路部材３０の固定接点部２４ａと外部接続端子２４ｒとの間には、上方からの平面視で、回路部材３０が延出する方向に対して交差する方向へ延出する許容部２４ｓが形成され、許容部２４ｓの幅寸法は、許容部２４ｓを間に挟んだ箇所の幅寸法よりも小さい、構成とした。 In the push switch 200 of the present embodiment, the circuit member 30 made of a metal plate and insert-molded in the case 23 has a fixed contact portion 24a at one end and is exposed from the rear side of the case 23 at the other end. The circuit member 30 extends between the fixed contact portion 24a of the circuit member 30 and the external connection terminal 24r in plan view from above. An allowable portion 24s extending in a direction crossing the direction is formed, and the width of the allowable portion 24s is smaller than the width of the portion sandwiching the allowable portion 24s therebetween.

プッシュスイッチ２００が電子機器などに取り付けられる場合には、プッシュスイッチ２００は、図１６に示すような、切り欠きが設けられた基板ＣＢ２に取り付けられる。プッシュスイッチ２００は、基板ＣＢ２の切り欠き部分の端部と切り欠き部２４ｍとが係合するとともに、外部接続端子２４ｒおよびケース２３の複数個所を基板ＣＢ２の上面に設けられたランドＬＮ２上に配置され、半田付けなどにより固定される。これにより、例えば、電子機器に搭載された状態で押し込み操作をされたとき、外部接続端子２４ｒは電子機器に半田付けなどにより固定されているため、押し込み荷重は外部接続端子２４ｒに加わることになる。外部接続端子２４ｒと固定接点部２４ａとの間に、前後の箇所より幅寸法が小さい許容部２４ｓを設けることで、押し込み操作をされたときに、押し込みされた方向へ微少量ではあるが許容部２４ｓが撓むことで、外部接続端子２４ｒにかかる負荷を吸収し軽減することができる。したがって、押し込み操作により半田付けされた外部接続端子２４ｒが外れるような不具合が発生し難くなる。よって、さらに押し込み耐性の高いプッシュスイッチを提供することができる、という効果を奏する。 When the push switch 200 is attached to an electronic device or the like, the push switch 200 is attached to a substrate CB2 provided with a notch as shown in FIG. In the push switch 200, the end of the cutout portion of the substrate CB2 and the cutout portion 24m are engaged, and the external connection terminal 24r and a plurality of places of the case 23 are disposed on the land LN2 provided on the upper surface of the substrate CB2. And fixed by soldering or the like. Thereby, for example, when a push-in operation is performed in a state where the electronic device is mounted on the electronic device, the external connection terminal 24r is fixed to the electronic device by soldering or the like, so that the push-in load is applied to the external connection terminal 24r. . By providing an allowance portion 24s having a smaller width than the front and rear portions between the external connection terminal 24r and the fixed contact portion 24a, when the push operation is performed, the allowance portion is slightly small in the pushed-in direction. By bending 24s, the load applied to the external connection terminal 24r can be absorbed and reduced. Therefore, it is difficult to cause a problem that the external connection terminal 24r soldered by the pushing operation is detached. Therefore, it is possible to provide a push switch with higher push resistance.
