Description

本発明は、本体カバーに形成された挿通孔に挿通され、本体側への押し込み変位により本体内のスイッチ素子を操作する押圧子と、前記押圧子を本体カバーよりも外方で片持ち状態で保持する弾性保持片と、を備えたスイッチ構造に関する。   The present invention includes a pressing element which is inserted into an insertion hole formed in the main body cover and operates a switch element in the main body by a pressing displacement toward the main body side, and the pressing element is in a cantilever state outside the main body cover. The present invention relates to a switch structure including an elastic holding piece.

上記のような従来のスイッチ構造として特許文献１に記載のものが知られている。かかるスイッチ構造では、押圧子又はそれを保持する弾性保持片が本体側に向けて押圧されると、弾性保持片の弾性復元力に抗して押圧子が本体側へ押し込み変位して、当該変位した押圧子により本体内のスイッチ素子が押圧操作される。一方、押圧子又は弾性保持片に対する押圧が解除されると、弾性保持片の弾性復元力により押圧子が本体とは反対側に変位して、本体内のスイッチ素子の押圧操作が解除される。   As a conventional switch structure as described above, the one described in Patent Document 1 is known. In such a switch structure, when the pressing element or the elastic holding piece that holds the pressing element is pressed toward the main body, the pressing element is pushed and displaced toward the main body against the elastic restoring force of the elastic holding piece. The switch element in the main body is pressed by the pressed element. On the other hand, when the pressure on the pressing element or the elastic holding piece is released, the pressing element is displaced to the side opposite to the main body by the elastic restoring force of the elastic holding piece, and the pressing operation of the switch element in the main body is released.

特開平０８−２３５９５６号公報Japanese Patent Laid-Open No. 08-235958

上記のような押圧子が弾性保持片により本体カバーよりも外方で片持ち状態で保持されているスイッチ構造では、本体カバーに押圧子が挿通する挿通孔を形成する必要があるため、本体カバーの強度低下や当該挿通孔を介した本体内への塵埃や虫や結露水等（以下「塵埃等」と呼ぶ。）の浸入が問題となる。
特に、弾性保持片の自由端側に押圧子を固定した場合、その押圧子は、本体側への押し込み変位の際に、押し込み方向の奥側ほど弾性保持片の固定端側に変位させて傾斜する姿勢に変化する。即ち、押圧子を本体側へ押し込み変位させると、挿通孔を挿通する押圧子の部位が、本体カバーの面内方向において弾性保持片の固定端側に近づく方向に変位する。よって、本体カバーに形成される挿通孔の大きさは、このような押圧子の姿勢変化を許容するべく、押圧子の外形よりも十分大きめに設定する必要がある。このことで、上述のような本体カバーの強度低下や塵埃等の浸入の問題が顕著となる。 In a switch structure in which the above-described pressing element is held in a cantilevered state outside the main body cover by the elastic holding piece, it is necessary to form an insertion hole through which the pressing element is inserted in the main body cover. There is a problem that the strength is reduced and the intrusion of dust, insects, condensed water, etc. (hereinafter referred to as “dust etc.”) into the main body through the insertion hole.
In particular, when the pressing element is fixed to the free end side of the elastic holding piece, the pressing element is inclined by being displaced toward the fixed end side of the elastic holding piece toward the back side in the pressing direction at the time of pressing displacement to the main body side. The posture changes. That is, when the pressing element is pushed and displaced toward the main body, the portion of the pressing element that is inserted through the insertion hole is displaced in a direction approaching the fixed end side of the elastic holding piece in the in-plane direction of the main body cover. Therefore, it is necessary to set the size of the insertion hole formed in the main body cover to be sufficiently larger than the outer shape of the presser to allow such a change in the posture of the presser. As a result, the problems of the strength reduction of the main body cover and the intrusion of dust and the like as described above become significant.

この実情に鑑み、本発明の主たる課題は、本体カバーの挿通孔に挿通されている押圧子が、弾性保持片により本体カバーよりも外方で片持ち状態で保持されているスイッチ構造において、本体カバーを補強すると共に、挿通孔を介した本体内への塵埃等の浸入を抑制する技術を提供する点にある。   In view of this situation, the main problem of the present invention is that in the switch structure in which the pressing member inserted through the insertion hole of the main body cover is held in a cantilever state outside the main body cover by the elastic holding piece, The present invention is to provide a technique for reinforcing the cover and suppressing intrusion of dust and the like into the main body through the insertion hole.

本体カバーに形成された挿通孔に挿通され、本体側への押し込み変位により本体内のスイッチ素子を操作する押圧子と、
前記押圧子を本体カバーよりも外方で片持ち状態で保持する弾性保持片と、を備えたスイッチ構造において、
前記本体カバーに、前記挿通孔の外周縁部から少なくとも外方に突出する筒状のスリーブ部を備えてもよい。 Inserted into the insertion hole formed in the body cover, a pushing element for operating the switching elements in the body by a pushing displacement in the main body,
In the switch structure with an elastic holding piece for holding in a cantilever state the pushing element at the outside than the body cover,
The body cover may comprise a cylindrical sleeve portion which projects at least outward from the outer peripheral edge of the insertion hole.

本構成によれば、本体カバーの挿通孔の外周縁にスリーブ部が設けられているので、当該挿通孔の外周縁部の強度が向上する。更に、このスリーブ部が挿通孔の外周縁から外方に突出するように設けられているので、本体カバーの外表面を伝って挿通孔に近づく塵埃等は、当該スリーブ部が障壁となって挿通孔に浸入し難くなる。
従って、本発明により、本体カバーの挿通孔に挿通されている押圧子が、弾性保持片により本体カバーよりも外方で片持ち状態で保持されているスイッチ構造において、本体カバーを補強すると共に、挿通孔を介した本体内への塵埃等の浸入を抑制する技術を提供することができる。 According to this configuration, since the sleeve portion on the outer periphery of the insertion hole of the cover is provided, the strength of the outer peripheral edge portion of the insertion hole is improved. Further, since the sleeve portion is provided so as to protrude outward from the outer peripheral edge of the insertion hole, dust or the like that approaches the insertion hole along the outer surface of the main body cover is inserted through the sleeve portion as a barrier. It becomes difficult to enter the hole.
Therefore, according to the present invention, in the switch structure in which the pressing member inserted into the insertion hole of the main body cover is held in a cantilever state outside the main body cover by the elastic holding piece, the main body cover is reinforced. It is possible to provide a technique for suppressing entry of dust and the like into the main body through the insertion hole.

前記スリーブ部の内周面のうち少なくとも前記弾性保持片の固定端側の面が、前記押圧子の押し込み方向の奥側ほど前記固定端側に位置するテーパー状に形成されてもよい。 Is pre-Symbol presser is fixed to the free end of the elastic retaining piece,
Of the inner peripheral surface of the sleeve portion, at least the surface on the fixed end side of the elastic holding piece may be formed in a tapered shape located closer to the fixed end side toward the back side in the pressing direction of the presser.

本構成によれば、弾性保持片の自由端側に押圧子が固定されているので、その押圧子は、本体側への押し込み変位の際に、押し込み方向の奥側ほど弾性保持片の固定端側に変位させて傾斜する姿勢に変化する。それに対し、スリーブ部の内周面のうち少なくとも弾性保持片の固定端側の面が上記のようなテーパー状に形成されおり、押圧子の押し込み移動に伴う姿勢変化をスリーブ部の内周面が邪魔することがないので、当該スリーブ部の外方側の端部の開口部をできるだけ小さくして、押圧子との間の隙間を介して本体内に塵埃等が浸入することを抑制することができる。 According to this configuration, since the pushing element on the free end side of the elastic holding pieces are fixed, the pressing element, when the push-displacement in the main body, the push-in direction of the back side as the elastic holding pieces fixed The posture changes to an end side and tilts. On the other hand, at least the surface of the elastic holding piece on the fixed end side of the inner peripheral surface of the sleeve portion is formed in a taper shape as described above, and the inner peripheral surface of the sleeve portion is subject to the posture change accompanying the pushing movement of the presser. Since there is no hindrance, it is possible to suppress the intrusion of dust or the like into the main body through the gap between the presser by making the opening at the outer end of the sleeve portion as small as possible. it can.

前記押圧子における前記弾性保持片との接続部側に、前記スイッチ素子が操作される設定押し込み位置に前記押圧子が押し込み変位したときに前記スリーブ部の端部と当接する当接部を備えてもよい。 The connection portion between the elastic holding pieces before Symbol presser includes an end abutment portion abutting of the sleeve portion when the pushing element pushes displaced to set the pushed-in position of the switching element is operated May be .

本構成によれば、押圧子の押し込み変位の際に、上記当接部が上記スリーブ部の端部と当接することにより、当該押圧子の設定押し込み位置よりも奥側への変位を規制して、スイッチ素子の過剰な押圧を回避することができる。
本発明の第１特徴構成は、本体カバーに形成された挿通孔に挿通され、本体側への押し込み変位により本体内のスイッチ素子を操作する押圧子と、
前記押圧子を本体カバーよりも外方で片持ち状態で保持する弾性保持片と、を備えたスイッチ構造であって、
前記本体カバーに、前記挿通孔の外周縁部から少なくとも外方に突出する筒状のスリーブ部を備え、
前記押圧子の姿勢は、押圧時において、押し込み方向の奥側ほど前記弾性保持片の固定端側に変位させて傾斜する傾斜姿勢に変化し、
前記挿通孔の大きさが、前記押圧子の前記傾斜姿勢への姿勢変化を許容するように設定されていると共に、前記スリーブ部の外方側の端部の開口部が前記挿通孔よりも小さく設定されている点にある。
本発明の第２特徴構成は、前記スリーブ部の内周面のうち少なくとも前記弾性保持片の固定端側の面が、前記傾斜姿勢に変化した前記押圧子の外面に沿うように形成されている点にある。
本発明の第３特徴構成は、前記押圧子の姿勢は、非押圧時において、前記本体カバーに対して略直交する方向に軸心を沿わせた直交姿勢となり、
前記挿通孔の大きさが、前記押圧子の前記直交姿勢から前記傾斜姿勢への姿勢変化を許容するように設定されている点にある。 According to this configuration, when the pressing element is displaced, the contact portion abuts the end of the sleeve portion, thereby restricting the displacement of the pressing element to the back side from the set pushing position. Further, excessive pressing of the switch element can be avoided.
The first characteristic configuration of the present invention is a pressing element that is inserted into an insertion hole formed in the main body cover and operates a switch element in the main body by pushing displacement toward the main body side,
An elastic holding piece that holds the presser in a cantilevered state outside the main body cover, and a switch structure comprising:
The main body cover includes a cylindrical sleeve portion that protrudes at least outward from an outer peripheral edge portion of the insertion hole,
At the time of pressing, the posture of the pressing element changes to an inclined posture that is inclined by being displaced toward the fixed end side of the elastic holding piece toward the back side in the pushing direction,
The size of the insertion hole is set so as to allow the posture change of the pressing element to the inclined posture, and the opening at the outer end of the sleeve portion is smaller than the insertion hole. It is in the set point.
According to a second characteristic configuration of the present invention, at least a surface on the fixed end side of the elastic holding piece among the inner peripheral surface of the sleeve portion is formed along the outer surface of the pressing element changed to the inclined posture. In the point.

本発明の実施形態について、図面に基づいて説明する。
図１に示す本実施形態のスイッチ構造１０は、例えば警報器や測定器などのような各種電気機器に適用可能なスイッチ構造として構成されている。かかるスイッチ構造１０は、スイッチ素子１１を操作するための押圧子１３と、当該押圧子１３を保持する弾性保持片１４とを備える。
押圧子１３は、電気機器の本体１の外表面を覆う本体カバー２に形成された挿通孔２ａに挿通され、本体１側への押し込み変位により本体１内のスイッチ素子１１を操作するものとして構成されている。一方、弾性保持片１４は、押圧子１３を本体カバー２よりも外方で片持ち状態で保持するものとして構成されている。 Embodiments of the present invention will be described with reference to the drawings.
The switch structure 10 of the present embodiment shown in FIG. 1 is configured as a switch structure applicable to various electric devices such as an alarm device and a measuring device. The switch structure 10 includes a pressing element 13 for operating the switching element 11 and an elastic holding piece 14 that holds the pressing element 13.
The pressing element 13 is configured to be inserted into an insertion hole 2a formed in the main body cover 2 that covers the outer surface of the main body 1 of the electric device, and to operate the switch element 11 in the main body 1 by pushing displacement toward the main body 1 side. Has been. On the other hand, the elastic holding piece 14 is configured to hold the pressing element 13 in a cantilever state outside the main body cover 2.

押圧子１３と弾性保持片１４とは、一体成形された樹脂製の押圧部材１２が有する部位として設けられている。
押圧部材１２が有する弾性保持片１４は、本体カバー２よりも外方に配置され、当該本体カバー２と略平行に延びる板状又は棒状に形成されている。また、この弾性保持片１４の本体カバー２に対する遠近方向での厚みは、当該弾性保持片１４が所望の弾性復元力を発現させながら湾曲可能な程度に設定されている。 The pressing element 13 and the elastic holding piece 14 are provided as parts of the integrally formed resin pressing member 12.
The elastic holding piece 14 of the pressing member 12 is disposed on the outer side of the main body cover 2 and is formed in a plate shape or a rod shape extending substantially parallel to the main body cover 2. Further, the thickness of the elastic holding piece 14 in the perspective direction with respect to the main body cover 2 is set such that the elastic holding piece 14 can be bent while exhibiting a desired elastic restoring force.

弾性保持片１４の一方側（図１及び図２において上方側）の端部には、本体カバー２に向かう方向（図１及び図２において右方向）に延びる柱状の支持柱体１５が形成されている。この支持柱体１５は、先端部に形成された係止部１５ａを本体カバー２に形成された係止孔２ｂに係止させる形態で、本体カバー２に固定される。
一方、弾性保持片１４の他方側（図１及び図２において下方側）の端部には、本体カバー２に向かう方向に延びる円柱状の押圧子１３が形成されている。この押圧子１３は、本体カバー２に形成された挿通孔２ａに挿通されて、その先端部をスイッチ素子１１に当接させる状態で配置されている。 A columnar support column 15 extending in a direction toward the main body cover 2 (right direction in FIGS. 1 and 2) is formed at one end (upper side in FIGS. 1 and 2) of the elastic holding piece 14. ing. The support column 15 is fixed to the main body cover 2 in such a manner that a locking portion 15 a formed at the distal end portion is locked in a locking hole 2 b formed in the main body cover 2.
On the other hand, a columnar pressing element 13 extending in the direction toward the main body cover 2 is formed at the end of the other side (the lower side in FIGS. 1 and 2) of the elastic holding piece 14. The pressing element 13 is inserted in an insertion hole 2 a formed in the main body cover 2, and is arranged in a state in which a tip portion thereof is in contact with the switch element 11.

即ち、弾性保持片１４は、本体カバー２に固定される支持柱体１５が突出形成された一方側の端部を固定端とし、押圧子１３が固定された他方側の端部を自由端とする状態で、本体カバー２の挿通孔２ａに挿通される押圧子１３を片持ち状態で保持するものとなる。   In other words, the elastic holding piece 14 has one end portion on which the support column 15 fixed to the main body cover 2 is protruded as a fixed end, and the other end portion to which the pressing element 13 is fixed as a free end. In this state, the pressing element 13 inserted through the insertion hole 2a of the main body cover 2 is held in a cantilever state.

そして、押圧子１３又はそれを保持する弾性保持片１４が本体１側に向けて押圧される押圧時において、図２に示すように、弾性保持片１４が湾曲しながら、当該弾性保持片１４の弾性復元力に抗して押圧子１３が本体１側（図２において右側）へ押し込み変位する。すると、当該変位した押圧子１３により本体１内のスイッチ素子１１が押圧操作されることになる。
一方、押圧子１３又は弾性保持片１４に対する押圧が解除される非押圧時において、図１に示すように、弾性保持片１４の湾曲が解消されながら、当該弾性保持片１４の弾性復元力により押圧子１３が本体１とは反対側（図１において左側）に変位する。すると、本体１内のスイッチ素子１１の押圧操作が解除されることになる。 When the pressing element 13 or the elastic holding piece 14 holding the pressing element 13 is pressed toward the main body 1, the elastic holding piece 14 is curved while the elastic holding piece 14 is curved as shown in FIG. 2. The pressing element 13 is pushed and displaced toward the main body 1 side (the right side in FIG. 2) against the elastic restoring force. Then, the switch element 11 in the main body 1 is pressed by the displaced pressing element 13.
On the other hand, when the pressure against the pressing element 13 or the elastic holding piece 14 is not pressed, the elastic holding piece 14 is pressed by the elastic restoring force while the bending of the elastic holding piece 14 is canceled as shown in FIG. The child 13 is displaced to the side opposite to the main body 1 (left side in FIG. 1). Then, the pressing operation of the switch element 11 in the main body 1 is released.

スイッチ構造１０の押圧子１３の姿勢は、図１に示す非押圧時において、本体カバー２に対して略直交する方向に軸心を沿わせた姿勢（以下、この姿勢を「直交姿勢」と呼ぶ。）となるが、図２に示す押圧時において、押し込み方向の奥側ほど弾性保持片１４の支持柱体１５側（固定端側）に変位させて傾斜する姿勢（以下、この姿勢を「傾斜姿勢」と呼ぶ。）に変化する。
よって、押圧子１３が挿通される本体カバー２の挿通孔２ａの大きさは、このような押圧子１３の直交姿勢から傾斜姿勢への姿勢変化を許容するべく、非押圧時において少なくとも弾性保持片１４の支持柱体１５に近い側において広めの隙間が形成されるように、押圧子１３の外形よりも十分大きめに設定する必要がある。そして、このように挿通孔２ａを大きめに形成すると、本体カバー２の強度低下や当該挿通孔２ａを介した本体１内への塵埃等の浸入が問題となる。
そこで、本実施形態のスイッチ構造１０は、本体カバー２を補強すると共に、挿通孔２ａを介した本体１内への塵埃等の浸入を抑制するための特徴構成を有しており、その特徴構成の詳細について、以下に説明を加える。 The posture of the pressing element 13 of the switch structure 10 is a posture in which the axis is aligned in a direction substantially orthogonal to the main body cover 2 when not pressed as shown in FIG. 1 (hereinafter, this posture is referred to as “orthogonal posture”). 2), however, when the pressure shown in FIG. 2 is pressed, the back of the pushing direction is displaced toward the support column 15 (fixed end side) of the elastic holding piece 14 (hereinafter referred to as “tilt”). Called “posture”).
Therefore, the size of the insertion hole 2a of the main body cover 2 through which the presser 13 is inserted is at least an elastic holding piece when not pressed so as to allow such a change in the posture of the presser 13 from the orthogonal posture to the inclined posture. It is necessary to set it to be sufficiently larger than the outer shape of the presser 13 so that a wide gap is formed on the side close to the support column body 14. If the insertion hole 2a is formed to be large in this way, there is a problem in that the strength of the main body cover 2 is reduced and dust or the like enters the main body 1 through the insertion hole 2a.
Therefore, the switch structure 10 of the present embodiment has a characteristic configuration for reinforcing the main body cover 2 and suppressing intrusion of dust or the like into the main body 1 through the insertion hole 2a. The details will be described below.

本体カバー２には、図３にも示すように、挿通孔２ａの外周縁部から押圧子１３の軸心方向に沿って突出する筒状のスリーブ部２０が設けられており、これにより、挿通孔２ａの外周縁部の強度が向上されている。
このスリーブ部２０としては、挿通孔２ａの外周縁部から外方（図３において上方）に突出する外スリーブ部２０Ａと、挿通孔２ａの外周縁部から内方（図３において下方）に突出する内スリーブ部２０Ｂとが設けられている。そして、少なくとも外スリーブ部２０Ａが設けられていることで、本体カバー２の外表面を伝って挿通孔２ａに近づく塵埃等は、当該外スリーブ部２０Ａが障壁となって、挿通孔２ａを介して本体１内に浸入し難くなる。 As shown in FIG. 3, the main body cover 2 is provided with a cylindrical sleeve portion 20 that protrudes from the outer peripheral edge portion of the insertion hole 2 a along the axial direction of the presser 13. The strength of the outer peripheral edge of the hole 2a is improved.
As the sleeve portion 20, an outer sleeve portion 20A that protrudes outward (upward in FIG. 3) from the outer peripheral edge portion of the insertion hole 2a, and an inner portion (downward in FIG. 3) protrudes from the outer peripheral edge portion of the insertion hole 2a. An inner sleeve portion 20B is provided. Since at least the outer sleeve portion 20A is provided, dust and the like approaching the insertion hole 2a along the outer surface of the main body cover 2 can be passed through the insertion hole 2a with the outer sleeve portion 20A serving as a barrier. It becomes difficult to enter the main body 1.

更に、スリーブ部２０は、図１及び図３に示すように、押圧子１３の押し込み方向の奥側（図１において右側、図３において下側）ほど内径及び外形が漸次拡大する形状、具体的には奥側が大径側である円錐台筒状に構成されている。この構成により、スリーブ部２０の内周面のうち少なくとも弾性保持片１４の固定端側（言い換えれば、支持柱体１５側）の面（以下、「固定端側内周面」と呼ぶ。）が、押圧子１３の押し込み方向の奥側ほど固定端側に位置するテーパー状に形成されることになる。この構成により、押圧子１３の押し込み移動に伴う姿勢変化をスリーブ部２０の内周面が邪魔することがないので、当該スリーブ部２０の外方側の端部２０ａの開口部をできるだけ小さくして、押圧子１３との隙間を介して本体１内に塵埃等が浸入することを抑制することができる。   Further, as shown in FIGS. 1 and 3, the sleeve portion 20 has a shape in which the inner diameter and the outer shape gradually increase toward the back side in the pushing direction of the presser 13 (the right side in FIG. 1 and the lower side in FIG. 3). Is configured in a truncated cone shape with the back side being the large diameter side. With this configuration, at least the surface of the inner peripheral surface of the sleeve portion 20 on the fixed end side (in other words, the support column 15 side) of the elastic holding piece 14 (hereinafter referred to as “fixed end side inner peripheral surface”). The inner side of the pressing element 13 in the pushing direction is formed in a tapered shape located on the fixed end side. With this configuration, since the inner peripheral surface of the sleeve portion 20 does not disturb the posture change accompanying the pushing movement of the presser 13, the opening portion of the outer end portion 20a of the sleeve portion 20 is made as small as possible. Intrusion of dust or the like into the main body 1 through the gap with the pressing element 13 can be suppressed.

更に、スリーブ部２０の内周面のテーパ角度は、傾斜姿勢に変化した押圧子１３の外面に沿うものに設定されている。即ち、図２に示すように、押圧子１３が本体１側へ押し込み変位する押圧時において、スリーブ部２０の固定端側の内周面が、傾斜姿勢に変化した押圧子１３の外面に沿ったものとなる。このことで、押圧子１３をスムーズに押し込み変位させることができる。   Furthermore, the taper angle of the inner peripheral surface of the sleeve portion 20 is set to be along the outer surface of the presser 13 changed to the inclined posture. That is, as shown in FIG. 2, when the presser 13 is pressed and displaced toward the main body 1, the inner peripheral surface on the fixed end side of the sleeve portion 20 is along the outer surface of the presser 13 changed to the inclined posture. It will be a thing. Thereby, the presser 13 can be pushed and displaced smoothly.

更に、上記スリーブ部２０の外方側（弾性保持片１４側）の端部２０ａの開口部では、押圧子１３の弾性保持片１４に対する接続部と近いことから、押圧子１３が弾性保持片１４の固定端側へ近づくような変位は少なくなる。よって、スリーブ部２０の端部２０ａの開口部とそれに挿通される押圧子１３との間の隙間を極力小さいものに設定して、その隙間を介して本体１内に塵埃等が浸入することを一層抑制することができる。   Further, since the opening portion of the end portion 20a on the outer side (the elastic holding piece 14 side) of the sleeve portion 20 is close to the connecting portion of the pressing piece 13 to the elastic holding piece 14, the pressing piece 13 is the elastic holding piece 14. Displacement that approaches the fixed end side is reduced. Therefore, the gap between the opening of the end portion 20a of the sleeve portion 20 and the presser 13 inserted through the opening is set to be as small as possible, and dust and the like enter the main body 1 through the gap. Further suppression can be achieved.

押圧子１３における弾性保持片１４との接続部側には、図３に示すように、押圧子１３の外周の４箇所において放射状に突出するリブ１６が形成されている。このようなリブ１６が形成されていることで、押圧子１３における弾性保持片１４との接続部の補強が行われている。
また、図２に示すように、この４箇所のリブ１６のうちの弾性保持片１４の自由端側のものは、スイッチ素子１１が操作される設定押し込み位置に押圧子１３が押し込み変位した押圧時において、スリーブ部２０の端部２０ａと当接する当接部として機能する。このことで、押圧子１３が設定押し込み位置よりも奥側への変位することが規制されて、スイッチ素子１１の過剰な押圧が回避されている。 As shown in FIG. 3, ribs 16 that project radially are formed at four locations on the outer periphery of the pressing element 13 on the side of the pressing element 13 that is connected to the elastic holding piece 14. By forming such a rib 16, the connection portion of the presser 13 with the elastic holding piece 14 is reinforced.
Also, as shown in FIG. 2, the elastic holding piece 14 of the four ribs 16 is on the free end side when the presser 13 is pushed and displaced to the set push position where the switch element 11 is operated. 2 functions as a contact portion that contacts the end portion 20a of the sleeve portion 20. As a result, the pressing element 13 is restricted from being displaced from the set pushing position to the back side, and excessive pressing of the switch element 11 is avoided.
