なく、上記問題への解決の要望が強くなってきている。In the prior art, when the thickness dimension of the case opening button hole 3 is made smaller than the size (planar dimension) of the button 1, the button 1 is not attached to the opening button hole 3 in the state shown in FIG. 2 (c). Get caught,
It has a fatal drawback that it causes a so-called clinging phenomenon and does not return to the state shown in FIG. 2 (a) even if the finger is released after pressing the button 1, and in recent years, electronic devices have been vigorously implemented. However, it cannot be applied to thin-design phones, and there is a growing demand for solutions to the above problems.
本考案の目的はこのような要望を実現できる押釦スイ
ッチを得るにある。An object of the present invention is to obtain a push button switch that can meet such a demand.

る。The push button switch of the present invention comprises a casing having an opening button hole for inserting a push button, a movable contact elastically movable,
A printed circuit board having a fixed electrode facing the lower part of the movable contact through a minute gap, a button having the movable contact at the lower part, and an upper part of the button from an opening button hole formed in the housing. In a push-button switch device in which the movable contact is separated from and brought into contact with the fixed electrode by projecting upward and downward through a gap, and the movable contact is separated from and in contact with the fixed electrode, and the casing is composed of one thin panel, and the button is cylindrical. The opening button hole has a trapezoidal cross section in which the rear side of the housing is larger than the front side, and the inclination angle of the ladder is Even when the button is pushed down to the maximum and tilted, the side surface of the button is set to a value not less than the inner peripheral surface of the opening button hole.
本考案の押釦スイッチにおいては、釦上面の一端部を
押下した場合は、釦は押下された側と反対側の他端ツバ
部を支点とする回転動作によって回動し、その後は下動
と回動を同時に行なって可動接点が固定電極に接するよ
うになる。In the push button switch of the present invention, when one end of the upper surface of the button is pressed, the button is rotated by the rotation operation with the other end flange portion on the opposite side to the pressed side as a fulcrum, and then downward movement and rotation. The movable contacts come into contact with the fixed electrode by simultaneously performing the movement.
以下図面によって本考案の実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第１図（ａ），（ｂ），（ｃ）は本考案の一実施例を
示す動作説明のための断面図で、きょう体２の開口釦穴
３は、きょう体２の表面側の穴寸法に対し裏面側をより
大きくする断面梯形状とし、釦１と開口釦穴３との隙間
はきょう体２の表面側は小さく、きょう体２の裏面側は
大きくする。1 (a), (b), and (c) are sectional views for explaining the operation of an embodiment of the present invention. The opening button hole 3 of the casing 2 is a hole on the front side of the casing 2. The back surface side is larger than the size, and the cross section has a trapezoidal shape.
なお、上記釦穴３の梯形の傾斜角が小さいと第３図に
示すように釦１の一側面が釦穴３の一側内周傾斜面に全
体として接触するようになり、押釦下時の摩擦抵抗が大
きくなると共に、上記くいつき現象を生ずるため、上記
傾斜角は第１図（ａ）〜（ｃ）に示すように上記釦１を
最大に押し下げ傾斜した場合でも上記釦１の一側面が釦
穴３の一側内周傾斜面に接しないようになる値以上とす
る必要がある。When the trapezoidal inclination angle of the button hole 3 is small, one side surface of the button 1 comes into contact with the one side inner peripheral inclined surface of the button hole 3 as a whole, as shown in FIG. Since the frictional resistance increases and the sticking phenomenon occurs, the tilt angle is one side surface of the button 1 even when the button 1 is pushed down to the maximum as shown in FIGS. 1 (a) to (c). It is necessary to have a value equal to or larger than a value at which the one side inner peripheral inclined surface of the buttonhole 3 is not contacted.
本考案の押釦スイッチは上記のような構成であるか
ら、釦１の上面一端部を押下すると、釦１は押下した側
と反対側のきょう体２の裏面と接している釦１の他端ツ
バ部１−１を支点として回動し、第１図（ｂ）のように

１が、その端押し側の側面をきょう体２の開口釦穴３の
表面側に接した状態を維持しながら下動し、第１図
（ｃ）に示すように可動接点４が基板６上の固定電極に
接するようになる。この場合釦１の他方の側の側面は釦
１が傾いても開口釦穴３の壁面とは接触せず、従って摩
擦力は増大せず、またきょう体２を薄いパネルで形成し
ても従来のように釦１と開口釦穴３との間にくいつき現
象を生ぜず、釦１が復旧しないという致命的な欠点を解
消できる。Since the push-button switch of the present invention has the above-mentioned structure, when one end of the upper surface of the button 1 is pressed, the other end of the button 1 which is in contact with the back surface of the casing 2 opposite to the pressed side is pressed. The part 1-1 rotates as a fulcrum, and the side surface on one side of the button 1 which is pushed as shown in FIG. 1 (b) comes into contact with the front side of the opening button hole 3 of the casing 2. After that, while maintaining the state that the button 1 is in contact with the side surface on the end pushing side of the button 2 on the front surface side of the opening button hole 3 of the casing 2 while gradually rotating the fulcrum to the opposite side and deepening the inclination. While moving downward, the movable contact 4 comes into contact with the fixed electrode on the substrate 6 as shown in FIG. In this case, the side surface on the other side of the button 1 does not come into contact with the wall surface of the opening button hole 3 even if the button 1 is tilted, so that the frictional force does not increase, and even if the housing 2 is formed of a thin panel, As described above, the fatal defect that the button 1 does not recover does not occur without causing the sticking phenomenon between the button 1 and the opening button hole 3.
以上説明したように本考案による押釦スイッチによれ
ば安定な釦動作を可能とし、よって信頼性の高い接点の
閉成，開離を行なう効果を有する。As described above, the push-button switch according to the present invention enables stable button operation, and thus has the effect of closing and opening contacts with high reliability.
