【先願発明】
横Ｕ字形ばね片（接点ばね片、ブラシ）とホルダー（プッシュレバー、作動子）を一体とした「接点ばね片」ユニットの構成は出願人がはじめて開発したものであり、これまで該接点ばね片ユニットに係る各種スイッチにつき多数件の特許出願を行っており、特開平５−２１１０２１号（特願平４−１８３００２号）（特許第３１１８０８６号）「プッシュスイッチ」特開平６−１２４６２３号（特願平４−２９７６６６号）「プッシュスイッチ」特開平１０−５０１７４号（特願平８−２１６１６４号）「スイッチのＵ形接点ばね片」などがある。

【００２９】
上記の特性によって、強固な基幹となるばね片ホルダーの幅と合わせて接点ばね片の幅及びプッシュレバーの幅（厚さ）を設定でき、よって、極めて小型かつ薄形のプッシュレバースイッチを構成できる革新的な特徴がある。
【００３０】
接点ばね片ユニットのばね片ホルダーのＵ形部カバーに小支軸を突設して、該小支軸をプッシュレバーの支軸と同心軸状に取付けたので、プッシュレバーの支軸を支点とした回動操作時に接点ばねユニットも同支点、同軌道回転することになって、操作用のアンバランスを生じない特徴がある。
【００３１】
プッシュレバーユニットを、プッシュレバーの支軸のスリットに接点ばね片ユニットの小支軸を通して両支軸を同心軸状に取付けると共に、プッシュレバーの下面に突設したリブに接点ばね片ユニットの内側接点ばね片のコ形部を嵌合するだけで、極めて簡単かつ迅速に組立て及び取外しができる利点があり、また、ケースに装着後は組立方向の外れを２重接点ばね片の弾力で有効に防止し得る特徴がある。
【００３２】
接点ばねユニットはそれを操作するプッシュレバー、押ボタン等の形状、寸法等に関係なくケース内等に設置してその作用、効果を発揮できる特性を有するので、該接点ばね片ユニットを独立した部材（パーツ）として、種々のスイッチに汎用し得る多大な利点がある。

[0002]
[Invention of prior application]
The configuration of the "contact spring piece" unit in which the horizontal U-shaped spring piece (contact spring piece, brush) and the holder (push lever, actuator) are integrated has been developed for the first time by the applicant, and the contact spring piece has hitherto been developed. A number of patent applications have been filed for various switches related to the unit. Japanese Patent Application Laid-Open No. Hei 5-212102 (Japanese Patent Application No. 4-183002) (Japanese Patent No. 3118086) "Push Switch" Japanese Patent Application Laid-open No. Hei 6-124623 (Japanese Patent Application) JP-A-4-297666) "Push switch" JP-A-10-50174 (Japanese Patent Application No. 8-216164), "U-shaped contact spring piece of switch" and the like.

[Conventional issues]
For example, the switch described in the above-mentioned Japanese Patent Application Laid-Open No. 10-50174 is provided in an extremely thin shape, and the U-shaped contact spring piece is composed of an inner and outer double narrow spring piece. When a contact spring piece unit is integrally mounted on a push lever (operator) to provide a contact spring piece unit, a support portion (a portion which does not perform a spring action on a spring contact action) is appropriately attached. However, there is a problem that it is difficult to stably attach a very small and narrow spring piece (for example, a width of 1.0 mm or less) to the push lever so that it can withstand several hundred thousand switching operations. Is small, narrow and double, and still has a low elasticity. Therefore, it is necessary to obtain a sufficient contact pressure that does not cause chattering between the contact of the spring piece and the fixed contact and to restore the original position of the push lever (actuator). Run short In order to make the push lever switch smaller and thinner than before, it is necessary to interpose a strong and stable connection between the U-shaped contact spring piece and the push lever, There has been a demand for the development and provision of effective means capable of increasing the elasticity of a piece.
[0004]
[Problems solved by the invention]
Therefore, the present invention provides a spring piece holder which is a strong metal U-shaped member prior to attaching the contact spring piece comprising the narrow inner and outer double spring pieces to the push lever. A "contact spring piece unit" which is firmly and integrally fixed by appropriate fixing means such as caulking or the like and has an increased elasticity of the spring piece in a durable and stable configuration is provided, and the contact spring piece unit is attached to the push lever. By providing a "push lever unit", we have solved the above-mentioned problems, and developed a general-purpose contact spring piece unit developed to solve the above-mentioned problems as a movable contact member (part) for various switches. Thus, the versatility of the U-shaped contact spring piece can be significantly improved in the future.

The push lever unit is inserted into the case, and its support shaft is pivotally supported by the shaft hole of the case so as to be rotatable at a set angle, and the contact of the outer contact spring piece of the double contact spring piece is used as the fixed contact of the case. In contact with (ON), the contact of the inner contact spring piece is provided opposite to the fixed contact of the case (OFF), and the push lever unit is urged upward about the support shaft by the restoring elasticity of the double contact spring piece. The problem has been solved by a push lever switch which is provided with an operation part which is turned and protrudes out of the case.

【effect】
The contact spring piece unit is fitted with a double contact spring piece into a strong metal spring piece holder in the state of accumulated power with its support and contact part compressed inward, and the support part is crimped to the mounting part, etc. The contact portion of each contact spring piece can have strong elasticity, and the width of the contact spring piece (set to be substantially the same width as the spring piece holder) is extremely small. Even if it is set, the operation and effect as a switch, that is, the operation and effect of maintaining the set contact pressure of the movable contact of the contact spring piece and the fixed contact of the case, preventing chattering, and cleaning by pressing and twisting are sufficient. Spring elasticity is obtained.
[0028]
Similarly, the contact spring piece unit is fitted with a double contact spring piece into a strong metal spring piece holder with its support part and the contact part inwardly compressed, and the support part is crimped to the mounting part. And the like, so that a contact spring piece unit having a very strong, stable and excellent durability can be provided.
[0029]
Due to the above characteristics, the width of the contact spring piece and the width (thickness) of the push lever can be set in accordance with the width of the spring piece holder which is a strong base, so that an extremely small and thin push lever switch can be configured. There are innovative features.
[0030]
The small support shaft protrudes from the U-shaped cover of the spring piece holder of the contact spring piece unit, and the small support shaft is mounted concentrically with the support shaft of the push lever. The contact spring unit also rotates at the same fulcrum and the same trajectory at the time of the turning operation described above, so that there is no unbalance for operation.
[0031]
Attach the push lever unit to the slit of the support shaft of the push lever through the small support shaft of the contact spring piece unit and attach both supports concentrically. At the same time, attach the inner contact of the contact spring piece unit to the rib protruding from the lower surface of the push lever. By simply fitting the U-shaped part of the spring piece, it has the advantage that it can be assembled and removed very easily and quickly, and after being mounted on the case, the detachment in the assembly direction is effectively prevented by the elasticity of the double contact spring piece. There are features that can be done.
[0032]
The contact spring unit is installed in a case or the like regardless of the shape, size, etc. of the push lever, push button, etc. that operates it, and has the property of exhibiting its function and effect. As (parts), there is a great advantage that can be used for various switches.
