【考案の詳細な説明】 ［産業上の利用分野］ 本考案は、切換え位置の保持機能を向上させたスライ
ドスイッチに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a slide switch having an improved function of holding a switching position.

［従来の技術］ ３ポジション式のスライドスイッチは実用に供されて
いる。この種のスイッチは、例えばA,B,Cの３個の接点
を有するとすると、Ａ−B,A−C,B−Ｃの３種のポジショ
ンを切換えることができ、この種のスイッチとしてスラ
イド式のものが用いられている。[Prior Art] A three-position slide switch is in practical use. If this type of switch has, for example, three contacts A, B, and C, three types of positions, AB, AC, and BC, can be switched. The formula type is used.

この種のスイッチは、ケース外に突出する摘みを左右
に摺動させてケース内のスライダを摺動させ、スライダ
側の可動接点をケース側の固定接点に対して移動させ、
例えば、左、中央、右の各位置で各接点相互を接続させ
るものである。ところで、スライダを各位置で確実に保
持せしめるため、スライダ裏面と、ケースの対向する壁
面間に、スライダを押圧するバネを介装し、かかるバネ
として、中間部を湾曲させた山型の細い横長の板バネが
用いられ、バネは単に壁面とスライダ裏面間に介装され
ているだけである。This type of switch slides a knob protruding out of the case left and right to slide a slider in the case, and moves a movable contact on the slider side with respect to a fixed contact on the case side,
For example, the respective contacts are connected to each other at left, center, and right positions. By the way, in order to securely hold the slider at each position, a spring that presses the slider is interposed between the back surface of the slider and the facing wall surface of the case, and as such a spring, a slender oblong shape having a curved middle portion is used. Is simply interposed between the wall surface and the slider back surface.

［考案が解決しようとする課題］ かかる従来構造は、上記板バネがケースの内壁面とス
ライダ裏面との間に介設（挟入）されているだけなの
で、以下のような不具合がある。[Problem to be Solved by the Invention] Such a conventional structure has the following inconveniences because the leaf spring is only interposed (inserted) between the inner wall surface of the case and the slider back surface.

即ち、バネはケース内壁面とスライダ裏面間に挟入さ
れ、この間で押圧されているだけなので、スライダの摺
動で右、或いは左にこれとともにケース内の隙間内でス
リップする可能性が有る。スライダが右、或いは左の位
置の場合は、バネがスリップしても、ケースのこの方向
の端部にバネ端部が当接し、スライダがこれとは反対方
向に押圧されて該位置での保持性が確実となる。一方、
バネの長さ方向とケースとの間に隙間があることから、
スライダを中央部にセットした際、バネが左右にスリッ
プする虞があり、これがため、スライダが左右に微動
し、当該位置での保持性が不安定となり、接触不良を生
じる虞が有る。That is, since the spring is sandwiched between the inner wall surface of the case and the back surface of the slider and is only pressed between the inner wall surface and the slider, there is a possibility that the slider slides to the right or to the left together with the slider in the gap in the case. When the slider is in the right or left position, even if the spring slips, the spring end abuts on the end in this direction of the case, and the slider is pressed in the opposite direction to hold the slider in that position. Sex is assured. on the other hand,
Because there is a gap between the length direction of the spring and the case,
When the slider is set at the center, the spring may slip left and right, which may cause the slider to slightly move left and right, making the holding property at the position unstable and causing a poor contact.

そこで、ケース側のバネと対応する壁面に対し、バネ
の長さ方向の精度を向上させれば、バネ両端部と壁面間
の隙間が無くなるので、バネは左右にガタ付かず、中央
部での保持性も確実化するが、一方、スイッチは極めて
小型であり、又、当然のこと乍らバネも極めて微小であ
り、ケース、バネの製作上、精度維持、精度管理が甚だ
しく困難で、ケースの組み付け誤差等を考慮すると、実
質上かかる方策は不可能に近い。Therefore, if the accuracy in the length direction of the spring is improved with respect to the wall corresponding to the spring on the case side, there is no gap between both ends of the spring and the wall, so that the spring does not rattle left and right, and the spring in the center part The switchability is also ensured, but on the other hand, the switch is extremely small, and naturally, the spring is also extremely small, and it is extremely difficult to maintain and control the accuracy of the case and the spring in manufacturing the spring. Considering assembly errors and the like, such a measure is practically impossible.

本考案は、かかる課題を解決すべくなされたもので、
その目的とする処は、上記したバネを、ケースとスライ

易いスイッチが得られる。[Effects of the Invention] As is apparent from the above description, according to the present invention, the slider, and thus the movable contact, has good holding properties at any of the three positions, and especially at the intermediate position, the spring is moved toward the case. The left and right direction is regulated and fixed by the locking recess and the locking piece, so there is a slight movement of the spring to the left and right due to the gap naturally generated between the left and right ends of the spring and the left and right parts of the case inner wall, with backlash Therefore, even if the slider and the movable contact face the conventional unstable intermediate position, they do not slightly move left and right or rattle, and the slider and the movable contact can be reliably held at the intermediate position. Thus, it is possible to eliminate defects such as poor connection at the intermediate position, and to obtain a three-position slide switch excellent in function. As a result of the above, it is possible to prevent backlash when operating this type of switch that requires a large number of manual operations, so that an operation feeling is improved and a switch that is easy to operate is obtained.

又、以上を、ケース内壁に凹部を設け、一方、バネに
は、一端部に係止部を下方に垂下延設し、これお凹部に
