　（プッシュスイッチ１００の概要）
　図１は、一実施形態に係るプッシュスイッチ１００の上方から見た外観斜視図である。図２は、一実施形態に係るプッシュスイッチ１００の下方から見た外観斜視図である。 (Overview of Push Switch 100)
FIG. 1 is an external perspective view of the push switch 100 according to the embodiment as viewed from above. FIG. 2 is an external perspective view of the push switch 100 according to the embodiment as viewed from below.
　図１および図２に示すプッシュスイッチ１００は、例えば、ＰＣ（Personal Computer）等に用いられるキーボードが備える複数の入力キーの各々に用いられるものである。図１および図２に示すように、プッシュスイッチ１００は、概ね直方体形状のハウジング１６０と、概ね直方体形状のスライダ１１０とを備えている。 The push switch 100 shown in FIGS. 1 and 2 is used for each of a plurality of input keys included in a keyboard used for, for example, a PC (Personal Computer) or the like. As shown in FIGS. 1 and 2, the push switch 100 includes a substantially rectangular parallelepiped housing 160 and a substantially rectangular parallelepiped slider 110.
　スライダ１１０は、ハウジング１６０に対して上下方向に移動可能に設けられている。また、図２に示すように、ハウジング１６０の底面からは、第１の外部接続端子１４１および第２の外部接続端子１５１が下方に突出して設けられている。 The slider 110 is provided so as to be movable in the vertical direction with respect to the housing 160. Further, as shown in FIG. 2, a first external connection terminal 141 and a second external connection terminal 151 are provided so as to project downward from the bottom surface of the housing 160.
　このように構成されたプッシュスイッチ１００は、操作者によってスライダ１１０が押下操作されることにより、スライダ１１０が下方に移動して、ハウジング１６０の底面から下方に突出して設けられた第１の外部接続端子１４１および第２の外部接続端子１５１を、互いに導通させることができる。 In the push switch 100 configured in this way, when the slider 110 is pressed by the operator, the slider 110 moves downward and is provided so as to project downward from the bottom surface of the housing 160. The terminal 141 and the second external connection terminal 151 can be made conductive with each other.
　なお、スライダ１１０は、ハウジング１６０の内部に設けられたコイルスプリング１２０（図３および図５参照）により、上方に付勢されている。これにより、スライダ１１０は、操作者による押下操作から解放されると、所定の高さ位置に自動的に復帰する。 The slider 110 is urged upward by a coil spring 120 (see FIGS. 3 and 5) provided inside the housing 160. As a result, the slider 110 automatically returns to a predetermined height position when released from the pressing operation by the operator.

　図３に示すように、プッシュスイッチ１００は、スライダ１１０、コイルスプリング１２０、リンク機構１３０、可動接点部材１４０、固定接点部材１５０、ハウジング１６０、および板バネ１７０を備える。 As shown in FIG. 3, the push switch 100 includes a slider 110, a coil spring 120, a link mechanism 130, a movable contact member 140, a fixed contact member 150, a housing 160, and a leaf spring 170.
　＜スライダ１１０＞
　スライダ１１０は、「操作部材」の一例であり、操作者による押下操作がなされる部材である。スライダ１１０は、例えば、合成樹脂素材が用いられて形成される。スライダ１１０は、リンク機構１３０を介して、ハウジング１６０に対して上下方向へ移動可能に支持される。スライダ１１０は、概ね直方体形状を有する。 <Slider 110>
The slider 110 is an example of an "operation member", and is a member that is pressed by an operator. The slider 110 is formed, for example, by using a synthetic resin material. The slider 110 is movably supported in the vertical direction with respect to the housing 160 via the link mechanism 130. The slider 110 has a substantially rectangular parallelepiped shape.
　図４および図５に示すように、スライダ１１０の内部には、下側が開口した収容空間１１０Ａを有する。収容空間１１０Ａは、上下方向（Ｚ軸方向）からの平面視において、ハウジング１６０の外形状よりも僅かに大きい矩形状を有する。 As shown in FIGS. 4 and 5, a storage space 110A having an open lower side is provided inside the slider 110. The accommodation space 110A has a rectangular shape slightly larger than the outer shape of the housing 160 in a plan view from the vertical direction (Z-axis direction).
　収容空間１１０Ａには、下側の開口からハウジング１６０が挿通される。スライダ１１０は、上下方向への移動に伴い、収容空間１１０Ａ内でハウジング１６０が上下方向に摺動する。これにより、スライダ１１０は、上下方向に移動する際の水平方向のガタが生じ難くなっている。 The housing 160 is inserted into the accommodation space 110A from the lower opening. As the slider 110 moves in the vertical direction, the housing 160 slides in the vertical direction in the accommodation space 110A. As a result, the slider 110 is less likely to play in the horizontal direction when moving in the vertical direction.
　スライダ１１０は、収容空間１１０Ａ内に配置されるコイルスプリング１２０によって、上方へ付勢される。このため、スライダ１１０は、ユーザによる押下操作がなされていないとき、所定の高さ位置にある。また、スライダ１１０は、ユーザによる押下操作から解放されると、所定の高さ位置まで自動的に復帰する。スライダ１１０の上面には、矩形状のシート１１１が貼付されている。例えば、シート１１１は、スライダ１１０の上面に形成されている孔を塞いで、当該孔からの埃等の浸入を防ぐ目的で設けられている。なお、シート１１１は、プッシュスイッチ１００の機能を示す文字が形成されたり、操作者に対して触感を呈示する粗面加工が施されたりしてもよい。 The slider 110 is urged upward by the coil spring 120 arranged in the accommodation space 110A. Therefore, the slider 110 is in a predetermined height position when no pressing operation is performed by the user. Further, when the slider 110 is released from the pressing operation by the user, the slider 110 automatically returns to a predetermined height position. A rectangular sheet 111 is attached to the upper surface of the slider 110. For example, the sheet 111 is provided for the purpose of closing a hole formed on the upper surface of the slider 110 and preventing dust or the like from entering through the hole. The sheet 111 may be formed with characters indicating the function of the push switch 100, or may be roughened to give a tactile sensation to the operator.
　スライダ１１０は、光透過性を有する部材が用いられて形成される。これにより、スライダ１１０は、例えば、スライダ１１０の裏側から光が照射された際に、スライダ１１０全体を発光させて、スライダ１１０に被せて取り付けられるつまみ（図示省略）に形成された文字を発光させることができる。この場合、シート１１１は、つまみに形成された文字を、乳白色且つ均等に発光させる効果を奏することができる。なお、シート１１１に文字等が形成されている場合、スライダ１１０は、シート１１１に形成された文字等のみを発光させるように構成されてもよい。 The slider 110 is formed by using a member having light transmission. As a result, for example, when the slider 110 is irradiated with light from the back side of the slider 110, the entire slider 110 is made to emit light, and a character formed on a knob (not shown) attached over the slider 110 is made to emit light. be able to. In this case, the sheet 111 can have the effect of causing the characters formed on the knobs to emit light in a milky white color evenly. When characters or the like are formed on the sheet 111, the slider 110 may be configured to emit only the characters or the like formed on the sheet 111.
　図４に示すように、収容空間１１０Ａの天井面には、一対の保持腕１１２、一対の軸支部１１３、および柱状部１１４が設けられている。 As shown in FIG. 4, a pair of holding arms 112, a pair of shaft support portions 113, and a columnar portion 114 are provided on the ceiling surface of the accommodation space 110A.
　一対の保持腕１１２は、収容空間１１０Ａの天井面のＸ軸負側において、Ｙ軸方向に並べて設けられている。一対の保持腕１１２は、後述するリンク機構１３０が備える第１のアーム部材１３１の軸部１３１Ａを回動可能に保持する。 The pair of holding arms 112 are provided side by side in the Y-axis direction on the negative side of the X-axis of the ceiling surface of the accommodation space 110A. The pair of holding arms 112 rotatably hold the shaft portion 131A of the first arm member 131 provided in the link mechanism 130 described later.
　柱状部１１４は、収容空間１１０Ａの天井面の中央に設けられている。柱状部１１４は、収容空間１１０Ａの天井面から下方に突出した円柱状を有する。柱状部１１４は、スライダ１１０の上下方向の移動に伴って、ハウジング１６０に設けられた筒部１６２内を、上下方向に摺動可能である。これにより、柱状部１１４は、スライダ１１０の左右方向のガタや、スライダ１１０の傾きを抑制することができる。また、図４および図５に示すように、柱状部１１４には、底面から上方に向って凹んだ凹み部１１４Ａが形成されている。凹み部１１４Ａの内壁面は、上方に向ってドーム状に湾曲した湾曲面となっている。これにより、柱状部１１４は、凹み部１１４Ａの下側から光が照射された場合に、凹み部１１４Ａの内壁面によって光を拡散して、スライダ１１０を均一に発光させることができる。 The columnar portion 114 is provided in the center of the ceiling surface of the accommodation space 110A. The columnar portion 114 has a columnar shape protruding downward from the ceiling surface of the accommodation space 110A. The columnar portion 114 is slidable in the vertical direction in the tubular portion 162 provided in the housing 160 as the slider 110 moves in the vertical direction. As a result, the columnar portion 114 can suppress backlash in the left-right direction of the slider 110 and tilt of the slider 110. Further, as shown in FIGS. 4 and 5, the columnar portion 114 is formed with a recessed portion 114A that is recessed upward from the bottom surface. The inner wall surface of the recessed portion 114A is a curved surface that is curved upward in a dome shape. As a result, when the columnar portion 114 is irradiated with light from the lower side of the recessed portion 114A, the light is diffused by the inner wall surface of the recessed portion 114A so that the slider 110 can emit light uniformly.
　一対の軸支部１１３は、Ｘ軸正側において、Ｙ軸方向に並べて設けられている。一対の軸支部１１３の各々には、Ｘ軸方向に延在するスライド溝１１３Ａが形成されている。これにより、一対の軸支部１１３は、スライド溝１１３Ａ内で、後述するリンク機構１３０が備える第２のアーム部材１３２の軸部１３２Ａの両端部を、Ｘ軸方向にスライド可能に支持する。 The pair of shaft support 113s are provided side by side in the Y-axis direction on the positive side of the X-axis. A slide groove 113A extending in the X-axis direction is formed in each of the pair of shaft support portions 113. As a result, the pair of shaft support portions 113 slidably support both ends of the shaft portion 132A of the second arm member 132 provided in the link mechanism 130, which will be described later, in the slide groove 113A in the X-axis direction.
　＜コイルスプリング１２０＞
　コイルスプリング１２０は、「付勢手段」の一例である。コイルスプリング１２０は、スライダ１１０の収容空間１１０Ａ内において、上下方向に弾性変形可能に配置される。コイルスプリング１２０の上側の環状開口部内には、スライダ１１０の収容空間１１０Ａの天井面に設けられた柱状部１１４が挿通される。コイルスプリング１２０の下側の環状開口部内には、ハウジング１６０の収容空間１６０Ａの内底面に設けられた筒部１６２が挿通される。これにより、コイルスプリング１２０は、左右方向へのガタや湾曲などが生じないように、上下方向に弾性変形可能となっている。コイルスプリング１２０は、スライダ１１０を上方に付勢する。これにより、コイルスプリング１２０は、スライダ１１０に対する押下操作が解放されたとき、スライダ１１０を所定の高さ位置まで自動的に復帰させることができる。 <Coil spring 120>
The coil spring 120 is an example of the “urging means”. The coil spring 120 is arranged so as to be elastically deformable in the vertical direction in the accommodation space 110A of the slider 110. A columnar portion 114 provided on the ceiling surface of the accommodation space 110A of the slider 110 is inserted into the annular opening on the upper side of the coil spring 120. A tubular portion 162 provided on the inner bottom surface of the accommodation space 160A of the housing 160 is inserted into the annular opening on the lower side of the coil spring 120. As a result, the coil spring 120 can be elastically deformed in the vertical direction so as not to cause backlash or bending in the horizontal direction. The coil spring 120 urges the slider 110 upward. As a result, the coil spring 120 can automatically return the slider 110 to a predetermined height position when the pressing operation on the slider 110 is released.
　＜リンク機構１３０＞
　リンク機構１３０は、第１のアーム部材１３１および第２のアーム部材１３２を有する。第１のアーム部材１３１は、互いに平行な一対の軸部１３１Ａ，１３１Ｂと、互いに平行な一対の連結部１３１Ｃ，１３１Ｄとを有して構成された、四角枠状の部材である。 <Link mechanism 130>
The link mechanism 130 has a first arm member 131 and a second arm member 132. The first arm member 131 is a square frame-shaped member having a pair of shaft portions 131A and 131B parallel to each other and a pair of connecting portions 131C and 131D parallel to each other.
　第２のアーム部材１３２は、互いに平行な一対の軸部１３２Ａ，１３２Ｂと、互いに平行な一対の連結部１３２Ｃ，１３２Ｄとを有して構成された、四角枠状の部材である。第２のアーム部材１３２のＹ軸方向の幅は、第１のアーム部材１３１のＹ軸方向の幅よりも小さくなっている。これにより、第２のアーム部材１３２は、第１のアーム部材１３１の枠内に配置可能となっている。 The second arm member 132 is a square frame-shaped member having a pair of shaft portions 132A and 132B parallel to each other and a pair of connecting portions 132C and 132D parallel to each other. The width of the second arm member 132 in the Y-axis direction is smaller than the width of the first arm member 131 in the Y-axis direction. As a result, the second arm member 132 can be arranged in the frame of the first arm member 131.
　第１のアーム部材１３１および第２のアーム部材１３２は、互いにＸ字状に交差するように、互いに組み合わされる。第１のアーム部材１３１および第２のアーム部材１３２は、互いに交差する部分に設けられた回動軸部１３０Ａによって、互いに回動可能に連結されている。これにより、リンク機構１３０は、スライダ１１０を昇降させる昇降機構として機能する。 The first arm member 131 and the second arm member 132 are combined with each other so as to intersect each other in an X shape. The first arm member 131 and the second arm member 132 are rotatably connected to each other by a rotation shaft portion 130A provided at a portion intersecting each other. As a result, the link mechanism 130 functions as an elevating mechanism for elevating and lowering the slider 110.
　第１のアーム部材１３１の上側（Ｚ軸正側）且つＸ軸負側の軸部１３１Ａは、スライダ１１０の収容空間１１０Ａの天井面に設けられた一対の保持腕１１２によって、回動可能に保持される。 The shaft portion 131A on the upper side (Z-axis positive side) and the X-axis negative side of the first arm member 131 is rotatably held by a pair of holding arms 112 provided on the ceiling surface of the accommodation space 110A of the slider 110. Will be done.
　第１のアーム部材１３１の下側（Ｚ軸負側）且つＸ軸正側の軸部１３１Ｂは、ハウジング１６０の収容空間１６０ＡのＹ軸方向における垂直な一対の側壁面に設けられた一対の軸支部１６３によって支持される。これにより、軸部１３１Ｂは、リンク機構１３０の昇降動作に伴って、一対の軸支部１６３に従ってＸ軸方向へ自由に移動可能である。すなわち、軸部１３１Ｂは、「リンク機構の昇降動作に伴って水平方向に移動する水平移動部」の一例である。軸部１３１Ｂは、可動接点部材１４０に形成されているＵ字状のフック１４３内に配置される（図５参照）。これにより、軸部１３１Ｂは、Ｘ軸方向への移動に伴って、可動接点部材１４０をＸ軸方向に伸縮させつつ、可動接点部材１４０に設けられた可動接点１４２を、Ｘ軸方向に移動させることができる。例えば、スライダ１１０を下方に押し下げられた場合、軸部１３１Ｂは、Ｘ軸正方向へ移動する。これにより、軸部１３１Ｂは、可動接点部材１４０をＸ軸正方向に伸張させつつ、可動接点１４２をＸ軸正方向に移動させて、可動接点１４２を固定接点１５２に接触させることができる。 The shaft portion 131B on the lower side (Z-axis negative side) and the X-axis positive side of the first arm member 131 is a pair of shafts provided on a pair of side wall surfaces perpendicular to the Y-axis direction of the accommodation space 160A of the housing 160. Supported by branch 163. As a result, the shaft portion 131B can freely move in the X-axis direction according to the pair of shaft support portions 163 as the link mechanism 130 moves up and down. That is, the shaft portion 131B is an example of a "horizontal moving portion that moves in the horizontal direction as the link mechanism moves up and down". The shaft portion 131B is arranged in a U-shaped hook 143 formed on the movable contact member 140 (see FIG. 5). As a result, the shaft portion 131B moves the movable contact member 142 provided on the movable contact member 140 in the X-axis direction while expanding and contracting the movable contact member 140 in the X-axis direction as the shaft portion 131B moves in the X-axis direction. be able to. For example, when the slider 110 is pushed down, the shaft portion 131B moves in the positive direction of the X-axis. As a result, the shaft portion 131B can move the movable contact member 142 in the positive direction of the X-axis while extending the movable contact member 140 in the positive direction of the X-axis, so that the movable contact 142 can be brought into contact with the fixed contact 152.
　第２のアーム部材１３２の上側（Ｚ軸正側）且つＸ軸正側の軸部１３２Ａは、当該軸部１３２Ａの両端部１３２Ｅが、スライダ１１０の収容空間１１０Ａの天井面に設けられた一対の軸支部１１３によって支持されるため、一対の軸支部１１３に従ってＸ軸方向にスライド可能である。 In the shaft portion 132A on the upper side (Z-axis positive side) and the X-axis positive side of the second arm member 132, both ends 132E of the shaft portion 132A are provided on the ceiling surface of the accommodation space 110A of the slider 110. Since it is supported by the shaft support 113, it can slide in the X-axis direction according to the pair of shaft support 113.
　第２のアーム部材１３２の下側（Ｚ軸負側）且つＸ軸負側の軸部１３２Ｂは、ハウジング１６０の収容空間１６０Ａの内底面に設けられた一対の保持腕１６１によって、回動可能に保持される。 The shaft portion 132B on the lower side (Z-axis negative side) and the X-axis negative side of the second arm member 132 can be rotated by a pair of holding arms 161 provided on the inner bottom surface of the accommodation space 160A of the housing 160. Be retained.
　このように構成されたリンク機構１３０は、スライダ１１０の上下移動にともなって、第１のアーム部材１３１が軸部１３１Ａを中心として回動し、第２のアーム部材１３２が軸部１３２Ｂを中心として回動することにより、第１のアーム部材１３１と第２のアーム部材１３２との交差角度が変化しつつ、上下方向（Ｚ軸方向）およびＸ軸方向に伸縮する。これにより、リンク機構１３０は、スライダ１１０の操作面（上面）の何れの位置が押された場合であっても、スライダ１１０の水平状態を保ったまま、スライダ１１０を下方へ移動させることができる。 In the link mechanism 130 configured in this way, the first arm member 131 rotates about the shaft portion 131A and the second arm member 132 rotates about the shaft portion 132B as the slider 110 moves up and down.

　（プッシュスイッチ１００の動作）
　図９および図１０は、一実施形態に係るプッシュスイッチ１００の動作を示す図である。図９は、スライダ１１０に対する押下操作がなされていない状態のプッシュスイッチ１００のＡ－Ａ断面線（図１参照）による断面を表している。図１０は、スライダ１１０に対する押下操作がなされた状態のプッシュスイッチ１００のＡ－Ａ断面線による断面を表している。 (Operation of push switch 100)
9 and 10 are diagrams showing the operation of the push switch 100 according to the embodiment. FIG. 9 shows a cross section of the push switch 100 in a state where the slider 110 is not pressed, according to the AA cross-sectional line (see FIG. 1). FIG. 10 shows a cross section of the push switch 100 in a state where the slider 110 is pressed, according to the AA cross section.
　図９に示すように、本実施形態のプッシュスイッチ１００は、スライダ１１０に対する下方への押下操作がなされると（図中Ｄ１）、第２のアーム部材１３２が、軸部１３２Ｂを中心に、Ｙ軸負側から見て時計回りに回動する（図中Ｄ２）。これにより、第２のアーム部材１３２の軸部１３２Ａの両端部１３２Ｅが、一対の軸支部１１３のスライド溝１１３Ａ内を、Ｘ軸正方向にスライド移動する（図中Ｄ３）。 As shown in FIG. 9, in the push switch 100 of the present embodiment, when a downward pressing operation with respect to the slider 110 is performed (D1 in the figure), the second arm member 132 is Y-centered on the shaft portion 132B. It rotates clockwise when viewed from the negative side of the shaft (D2 in the figure). As a result, both end portions 132E of the shaft portion 132A of the second arm member 132 slide and move in the X-axis positive direction in the slide grooves 113A of the pair of shaft support portions 113 (D3 in the drawing).
　同時に、第１のアーム部材１３１が、軸部１３１Ａを中心に、Ｙ軸負側から見て反時計回りに回動する（図中Ｄ４）。これにより、第１のアーム部材１３１の軸部１３１Ｂが、可動接点部材１４０のフック１４３内に保持された状態で、一対の軸支部１６３の水平溝内をＸ軸正側に水平移動することで、一端（Ｘ軸負側の端部）がハウジング１６０に固定された可動接点部材１４０を伸張させつつ、可動接点部材１４０のＸ軸正側の連結部１４０Ｄを、Ｘ軸正側に移動させる（図中Ｄ５）。 At the same time, the first arm member 131 rotates counterclockwise with respect to the shaft portion 131A when viewed from the negative side of the Y axis (D4 in the figure). As a result, the shaft portion 131B of the first arm member 131 is horizontally moved in the horizontal groove of the pair of shaft support portions 163 to the positive side of the X axis while being held in the hook 143 of the movable contact member 140. While extending the movable contact member 140 whose one end (the end on the negative side of the X axis) is fixed to the housing 160, the connecting portion 140D on the positive side of the X axis of the movable contact member 140 is moved to the positive side of the X axis ( D5) in the figure.
　これにより、図１０に示すように、可動接点部材１４０の連結部１４０Ｄに設けられた可動接点１４２が、当該可動接点１４２と対向して設けられた固定接点１５２と接触する。その結果、可動接点部材１４０に設けられた第１の外部接続端子１４１と、固定接点部材１５０に設けられた第２の外部接続端子１５１とが、互いに導通することとなる。 As a result, as shown in FIG. 10, the movable contact 142 provided in the connecting portion 140D of the movable contact member 140 comes into contact with the fixed contact 152 provided facing the movable contact 142. As a result, the first external connection terminal 141 provided on the movable contact member 140 and the second external connection terminal 151 provided on the fixed contact member 150 are electrically connected to each other.
　さらに、スライダ１１０に対する押下操作が解除されると、コイルスプリング１２０からの上方への付勢力により、スライダ１１０は、上方へ移動して（図中Ｄ６）、元の高さ位置に自動的に復帰する。この際、第１のアーム部材１３１の軸部１３１Ｂが、可動接点部材１４０のフック１４３内に保持された状態で、一対の軸支部１６３の水平溝内をＸ軸負側に水平移動することで、伸張した状態の可動接点部材１４０を元の状態に復帰させつつ、可動接点部材１４０のＸ軸正側の連結部１４０Ｄを、Ｘ軸負側に移動させる（図中Ｄ７）。これにより、図９に示すように、可動接点部材１４０の連結部１４０Ｄに設けられた可動接点１４２が、当該可動接点１４２と対向して設けられた固定接点１５２と離間した状態に復帰する。 Further, when the pressing operation on the slider 110 is released, the slider 110 moves upward (D6 in the figure) due to the upward urging force from the coil spring 120, and automatically returns to the original height position. To do. At this time, the shaft portion 131B of the first arm member 131 is horizontally moved in the horizontal groove of the pair of shaft support portions 163 to the negative side of the X axis while being held in the hook 143 of the movable contact member 140. While returning the movable contact member 140 in the extended state to the original state, the connecting portion 140D on the positive side of the X axis of the movable contact member 140 is moved to the negative side of the X axis (D7 in the figure). As a result, as shown in FIG. 9, the movable contact 142 provided in the connecting portion 140D of the movable contact member 140 returns to a state of being separated from the fixed contact 152 provided facing the movable contact 142.

That is, since the push switch 100 according to one embodiment can enhance the interlocking between the slider 110 and the movable contact 142, it is possible to present a direct switch operation feeling to the operator.
　また、一実施形態に係るプッシュスイッチ１００において、可動接点部材１４０は、水平方向における一端が、ハウジング１６０に固定され、水平方向における他端に、可動接点１４２を有し、リンク機構１３０の昇降動作に伴って、水平方向に伸縮することにより、可動接点１４２が水平方向に移動可能である。 Further, in the push switch 100 according to one embodiment, the movable contact member 140 has one end fixed to the housing 160 in the horizontal direction and the movable contact 142 at the other end in the horizontal direction, and the link mechanism 130 moves up and down. As a result, the movable contact 142 can move in the horizontal direction by expanding and contracting in the horizontal direction.
　これにより、一実施形態に係るプッシュスイッチ１００は、比較的簡単な構成で、可動接点１４２を水平方向に移動させることができる。また、一実施形態に係るプッシュスイッチ１００は、可動接点部材１４０の形状（例えば、フック１４３の位置）を変更することで、可動接点１４２と固定接点１５２との接触タイミングを容易に変更することができる。例えば、一実施形態に係るプッシュスイッチ１００は、可動接点部材１４０の形状を変更することで、スライダ１１０をフルストロークさせなくとも、可動接点１４２と固定接点１５２との接触させることもできる。すなわち、スライダ１１０が、操作者によって押圧されて移動可能な範囲における最下部に至る前に、可動接点１４２と固定接点１５２とが接触するように可動接点部材１４０を形状化することが可能である。 As a result, the push switch 100 according to the embodiment can move the movable contact 142 in the horizontal direction with a relatively simple configuration. Further, in the push switch 100 according to one embodiment, the contact timing between the movable contact 142 and the fixed contact 152 can be easily changed by changing the shape of the movable contact member 140 (for example, the position of the hook 143). it can. For example, in the push switch 100 according to one embodiment, by changing the shape of the movable contact member 140, the movable contact 142 and the fixed contact 152 can be brought into contact with each other without making the slider 110 a full stroke. That is, it is possible to shape the movable contact member 140 so that the movable contact 142 and the fixed contact 152 come into contact with each other before the slider 110 reaches the bottom of the movable range pressed by the operator. ..
　また、一実施形態に係るプッシュスイッチ１００において、可動接点部材１４０は、複数回折り曲げられつつ、水平方向に延在する形状を有することにより、水平方向に伸縮可能である。 Further, in the push switch 100 according to one embodiment, the movable contact member 140 can be expanded and contracted in the horizontal direction by having a shape extending in the horizontal direction while being bent a plurality of times.
　これにより、一実施形態に係るプッシュスイッチ１００は、可動接点部材１４０に容易にバネ性を持たせることができる。また、一実施形態に係るプッシュスイッチ１００は、折り曲げ形状等を変更することで、可動接点部材１４０のばね特性を容易に変更することができる。また、一実施形態に係るプッシュスイッチ１００は、可動接点部材１４０に折り曲げ部を複数設けたことによって、可動接点部材１４０に係る負荷を各折り曲げ部に分散することができ、よって、可動接点部材１４０の耐久性を高めることができる。 As a result, the push switch 100 according to the embodiment can easily give the movable contact member 140 a spring property. Further, the push switch 100 according to the embodiment can easily change the spring characteristics of the movable contact member 140 by changing the bent shape or the like. Further, in the push switch 100 according to one embodiment, by providing a plurality of bent portions in the movable contact member 140, the load related to the movable contact member 140 can be distributed to each bent portion, and thus the movable contact member 140. Durability can be increased.
　さらに、一実施形態に係るプッシュスイッチ１００は、ハウジング１６０に設けられた筒部１６２の内部に、任意の発光手段を設けることができるため、プッシュスイッチ１００全体の薄型化に影響を及ぼすことなく、スライダ１１０に対して裏側から光を照射して、スライダ１１０の少なくとも一部を発光させることができる。 Further, in the push switch 100 according to the embodiment, since any light emitting means can be provided inside the tubular portion 162 provided in the housing 160, the push switch 100 as a whole is not affected by the thinning. Light can be applied to the slider 110 from the back side to cause at least a part of the slider 110 to emit light.
　特に、一実施形態に係るプッシュスイッチ１００は、コイルスプリング１２０、リンク機構１３０、および可動接点部材１４０が、いずれも筒部１６２の周囲を取り囲む環状をなしているため、発光手段から出射された光が、これらの部材によって遮られないようにすることができる。したがって、一実施形態に係るプッシュスイッチ１００は、発光手段から出射された光の利用効率を高めることができる。 In particular, in the push switch 100 according to the embodiment, since the coil spring 120, the link mechanism 130, and the movable contact member 140 all form an annular shape surrounding the circumference of the tubular portion 162, the light emitted from the light emitting means is emitted. However, it can be prevented from being blocked by these members. Therefore, the push switch 100 according to the embodiment can improve the utilization efficiency of the light emitted from the light emitting means.
　また、一実施形態に係るプッシュスイッチ１００は、可動接点１４２が単純に固定接点１５２に接離する構成を採用しているため、可動接点１４２と固定接点１５２との摺動摩擦が殆ど生じることなく、よって、可動接点１４２および固定接点１５２の耐久性を高めることができる。 Further, since the push switch 100 according to the embodiment adopts a configuration in which the movable contact 142 is simply brought into contact with and separated from the fixed contact 152, there is almost no sliding friction between the movable contact 142 and the fixed contact 152. Therefore, the durability of the movable contact 142 and the fixed contact 152 can be improved.
