Description

本発明は、各種電子機器の操作用スイッチとして使用されるスライドスイッチ構造を有するスイッチ装置に関する。   The present invention relates to a switch device having a slide switch structure used as an operation switch for various electronic devices.

従来のスイッチ装置としては、複数の固定接点が配設された絶縁板と、これら固定接点と摺接する可動接片と、この可動接点を保持し摺動させる操作子と、これらを覆うカバー及びケースとによって構成されたものが知られている（例えば、特許文献１参照）。   As a conventional switch device, there are an insulating plate provided with a plurality of fixed contacts, a movable contact piece that is in sliding contact with the fixed contacts, an operation element that holds and slides the movable contacts, and a cover and a case that cover them. (For example, refer to Patent Document 1).

図９〜図１１は、該スイッチ装置の平面図を示したものであり、図９は可動接片が中立位置Ｎの状態、図１０は可動接片が第１位置ＭＤの状態、図１１は可動接点が第２位置ＡＤの状態を示す。図では操作子、カバー及びケースの図示を省略している。図において、絶縁板１はその上面に共通固定接点１１、第１固定接点１２，１３及び第２固定接点１４，１５を設けている。   9 to 11 show plan views of the switch device. FIG. 9 shows a state in which the movable contact piece is in the neutral position N, FIG. 10 shows a state in which the movable contact piece is in the first position MD, and FIG. The movable contact shows the state of the second position AD. In the figure, the operator, the cover, and the case are not shown. In the figure, the insulating plate 1 is provided with a common fixed contact 11, first fixed contacts 12, 13 and second fixed contacts 14, 15 on the upper surface thereof.

そして、絶縁板１には図示しないノブの操作位置に対応した中立位置Ｎ、第１位置ＭＵ，ＭＤ及び第２位置ＡＵ，ＡＤと、可動接片２の移動範囲に対応した第１領域Ｚ１及び第２領域Ｚ２とを設定している。詳述すると、中立位置Ｎとはノブの位置が中立位置である際の可動接片２の位置であり、第１位置ＭＵ，ＭＤとはノブの操作位置が１段目の操作位置である際の可動接片２の位置であり、第２位置ＡＵ，ＡＤとはノブの操作位置が１段目からさらに操作された２段目の操作位置である際の可動接片２の位置である。また第１領域Ｚ１とは共通固定接点１１と第１固定接点１２，１３とが並んだ領域であり、第２領域Ｚ２とは共通固定接点１１と第２固定接点１４，１５とが並んだ領域である。   The insulating plate 1 includes a neutral position N corresponding to an operation position of a knob (not shown), first positions MU and MD, second positions AU and AD, and a first area Z1 corresponding to a moving range of the movable contact piece 2 and A second area Z2 is set. More specifically, the neutral position N is the position of the movable contact piece 2 when the knob is in the neutral position, and the first positions MU and MD are when the knob operation position is the first stage operation position. The second positions AU and AD are the positions of the movable contact piece 2 when the operation position of the knob is the second operation position further operated from the first stage. The first region Z1 is a region where the common fixed contact 11 and the first fixed contacts 12 and 13 are arranged, and the second region Z2 is a region where the common fixed contact 11 and the second fixed contacts 14 and 15 are arranged. It is.

可動接片３２は、前記絶縁板３１に設定した中立位置Ｎ、第１位置ＭＵ，ＭＤ及び第２位置ＡＵ，ＡＤ間において移動自在であり、かつ前記絶縁板１の第１領域Ｚ１を摺動する第１接片２１と、第２領域Ｚ２を摺動する第２接片２２とを有している。   The movable contact piece 32 is movable between the neutral position N, the first positions MU and MD, and the second positions AU and AD set on the insulating plate 31, and slides on the first region Z1 of the insulating plate 1. And a second contact piece 22 that slides in the second region Z2.

次に、上記したものの作動を説明する。まず、図９はノブを操作しない状態であり、可動接片３２の移動位置が中立位置Ｎに有る状態を示している。この状態では、可動接片３２はいずれの固定接点１１〜１５にも接触していないので、２段スイッチ装置は信号を出力しない。   Next, the operation of the above will be described. First, FIG. 9 shows a state where the knob is not operated, and the moving position of the movable contact piece 32 is in the neutral position N. In this state, since the movable contact piece 32 is not in contact with any of the fixed contacts 11 to 15, the two-stage switch device does not output a signal.

また、図１０はノブを１段目の操作位置に操作した状態であり、可動接片３２が中立位置Ｎから第１位置ＭＤに移動した状態を示している。この状態では、可動接片３２が共通固定接点１１と第１固定接点１２との両方に接触し、両固定接点１１，１２間を橋絡する。これにより、２段スイッチ装置は１段目の信号を入力するものとなる。   FIG. 10 shows a state in which the knob is operated to the first-stage operation position, and the movable contact piece 32 has moved from the neutral position N to the first position MD. In this state, the movable contact piece 32 contacts both the common fixed contact 11 and the first fixed contact 12, and bridges between the two fixed contacts 11 and 12. As a result, the two-stage switch device inputs the first-stage signal.

また、図１１はノブを２段目の操作位置に操作した状態であり、可動接片３２が中立位置Ｎから第２位置ＡＤに移動した状態を示している。この状態では、可動接片３２が共通固定接点１１と第２固定接点１４との両方に接触し、両固定接点１１，１４間を橋絡する。これにより、２段スイッチ装置は２段目の信号を入力するものとなる。   FIG. 11 shows a state in which the knob is operated to the second operation position, and the movable contact piece 32 has moved from the neutral position N to the second position AD. In this state, the movable contact piece 32 contacts both the common fixed contact 11 and the second fixed contact 14, and bridges between the fixed contacts 11 and 14. As a result, the two-stage switch device inputs the second-stage signal.

また、基台に、スライド部材のスライド移動方向に沿って延びるガイド溝を設け、ガイド溝の両側に可動接点部材が摺動する一対の壁部を設け、この壁部に個別固定接点を形成したことから、球状の可動接点部材を確実に接触させることができる。
また、壁部を、球面状または斜面状に形成し、個別固定接点を壁部の一部に球面状または斜面状に突出させて一体に埋設して形成したことから、可動接点部材が摺動するガイド溝の壁部に導電部である個別固定接点と非導電部とを簡単に形成することができる。
また、個別固定接点またはガイド溝に、可動接点部材が摺動する際にクリック感触を生起させる段差部を設けたことから、スライド部材のスライド操作時にクリック感触を付与でき、良好な操作感触が得られる。
また、弾性部材は、導電性のばね部材からなり、ばね部材の他端側を共通固定接点と導通させたことから、共通固定接点との導通経路をばね部材で形成できるので、部品点数の削減が図れる。

It is formed in a box shape. A projecting portion 1c projecting outward is provided in the center of the outer surface of the side surface of the base 1 that faces the opening 1b, and engaging projections that engage the cover 8 on both sides of the projecting portion 1c. 1d is provided. Further, the other opposing side surfaces of the base portion 1 are also provided with engaging protrusions 1d that engage with the cover 8 in the same manner.

また、基台１の突出部１ｃが設けられた側面の内側面両側には、導電性の金属板からなる一対の共通固定接点２、２がその一部を表出して埋設されている。また、収納部１ａの内底面両側には、スライド部材４のスライド移動方向に沿って延びる一対の凹溝部１ｅ、１ｅが設けられており、これら凹溝部１ｅ、１ｅの内底面にもそれぞれ共通固定接点２、２の一部が表出されている。この一対の凹溝部１ｅ、１ｅに、弾性部材７が収容されて、この弾性部材７の一端側が駆動板５に当接され、他端側が共通固定接点２と導通した状態で配設されている。
また、共通固定接点２、２の他端側は、基台１の他の対向する側面の外方に導出されて、それぞれ接続端子２ａ、２ａが設けられている。 A pair of common fixed contacts 2 and 2 made of a conductive metal plate are embedded on both sides of the inner side surface of the side surface of the base 1 where the protruding portion 1c is provided. A pair of concave groove portions 1e and 1e extending along the sliding movement direction of the slide member 4 are provided on both sides of the inner bottom surface of the storage portion 1a. A part of the contacts 2 and 2 is exposed. An elastic member 7 is accommodated in the pair of concave grooves 1 e and 1 e, and one end side of the elastic member 7 is in contact with the drive plate 5, and the other end side is disposed in a state of being connected to the common fixed contact 2. .
Moreover, the other end side of the common fixed contacts 2 and 2 is derived | led-out outside the other opposing side surface of the base 1, and the connection terminals 2a and 2a are provided, respectively.

また、収納部１ａの内底面中央には、スライド部材４のスライド移動方向に沿って延びる凹状で細溝状のガイド溝１ｆが設けられており、このガイド溝１ｆの両側にはガイド溝１ｆの底部から延設された一対の壁部１ｇ、１ｈが設けられている。また、この一対の壁部１ｇ、１ｈは、ガイド部１ｆの底部から壁部１ｇ、１ｈの上面に向かって、互いに拡開する方向に球面状または斜面状に形成されている（本実施例では球面状）。また、ガイド溝１ｆの略中央には、スライド部材４のスライド移動方向に沿って壁部１ｇ、１ｈの高さを異ならせるための段差部１ｉが設けられている。また、一対の壁部１ｇ、１ｈの両側には、一対の凹溝部１ｅ、１ｅとの間に、それぞれ突条の隔壁１ｊ、１ｊが設けられている。   In addition, a concave and narrow guide groove 1f extending along the sliding movement direction of the slide member 4 is provided at the center of the inner bottom surface of the storage portion 1a, and guide grooves 1f are formed on both sides of the guide groove 1f. A pair of wall portions 1g and 1h extending from the bottom portion are provided. Further, the pair of wall portions 1g and 1h are formed in a spherical shape or a slope shape in a direction of expanding from the bottom portion of the guide portion 1f toward the upper surface of the wall portions 1g and 1h (in this embodiment). Spherical). Further, a stepped portion 1i for varying the heights of the wall portions 1g and 1h along the slide movement direction of the slide member 4 is provided at substantially the center of the guide groove 1f. Further, on both sides of the pair of wall portions 1g and 1h, rib partition walls 1j and 1j are provided between the pair of groove portions 1e and 1e, respectively.

また、ガイド溝１ｆの両側の一対の壁部１ｇ、１ｈには、略対向する位置に、同じく導電性の金属板からなる１段目スイッチ及び２段目スイッチの接点部を構成する、第１個別固定接点３ａ及び第２個別固定接点３ｂからなる個別固定接点３が、その一部を表出してそれぞれ埋設されている。この場合、それぞれの個別固定接点３は、一対の壁部１ｇ、１ｈの一部に球面状または斜面状（本実施例では球面状）に突出させて一体に埋設して形成されている。そして、この一対の壁部１ｇ、１ｈ上を可動接点部材６が摺動するものとなっており、可動接点部材６が順次、第１個別固定接点３ａ及び第２個別固定接点３ｂと摺接するものとなっている。   Further, the first stage switch and the second stage switch, which are also made of a conductive metal plate, are formed at substantially opposite positions on the pair of wall parts 1g and 1h on both sides of the guide groove 1f. A part of the individual fixed contact 3 composed of the individual fixed contact 3a and the second individual fixed contact 3b is exposed and embedded. In this case, each of the individual fixed contacts 3 is formed by being embedded in a part of a pair of wall portions 1g, 1h so as to protrude in a spherical shape or a slope shape (spherical shape in this embodiment). The movable contact member 6 slides on the pair of wall portions 1g and 1h, and the movable contact member 6 sequentially contacts the first individual fixed contact 3a and the second individual fixed contact 3b. It has become.

このように、一対の壁部１ｇ、１ｈを、球面状に形成し、第１及び第２個別固定接点３ａ、３ｂを一対の壁部１ｇ、１ｈの一部に球面状に突出させて一体に埋設して形成したことから、可動接点部材６が摺動するガイド溝１ｆの壁部１ｇ、１ｈに導電部である個別固定接点３と非導電部とを簡単に形成することができるものとなっている。   In this way, the pair of wall portions 1g and 1h are formed into a spherical shape, and the first and second individual fixed contacts 3a and 3b are projected into a spherical shape on a part of the pair of wall portions 1g and 1h so as to be integrated. Since it is embedded and formed, the individual fixed contact 3 as a conductive portion and the nonconductive portion can be easily formed on the wall portions 1g and 1h of the guide groove 1f on which the movable contact member 6 slides. ing.

また、この時、ガイド溝１ｆの略中央には、スライド部材４のスライド移動方向に沿って壁部１ｇ、１ｈの高さを異ならせる段差部１ｉが設けられており、この段差部１ｉを設けることにより、スライド部材４がスライド移動する際に、可動接点部材６が壁部１ｇ、１ｈ上を摺動して段差部１ｉに当接することで、スライド部材４のスライド操作時にクリック感触を付与でき、良好な操作感触が得られるものとなっている。
また、それぞれの個別固定接点３の他端側は、基台１の側面に設けられた突出部１ｃの外方に導出されて、それぞれ接続端子３ｃ及び３ｄが設けられている。 At this time, a step portion 1i is provided at approximately the center of the guide groove 1f so as to vary the height of the wall portions 1g and 1h along the slide movement direction of the slide member 4. The step portion 1i is provided. Thus, when the slide member 4 slides, the movable contact member 6 slides on the wall portions 1g and 1h and comes into contact with the stepped portion 1i, so that a click feeling can be given during the slide operation of the slide member 4. A good operation feeling can be obtained.
Further, the other end side of each individual fixed contact 3 is led out of the protruding portion 1c provided on the side surface of the base 1, and is provided with connection terminals 3c and 3d, respectively.

また、図２、図５に示すように、基台１の開口部１ｂから見て左側に位置する１段目スイッチである第１個別固定接点３ａは、右側に位置する２段目スイッチである第２個別固定接点３ｂに比べて、可動接点部材６の摺動方向すなわちスライド部材４のスライド移動方向の前端側（開口部１ｂ側）の表出部の長さが若干長く形成されている。このため、スライド部材４のスライド移動時には、可動接点部材６が第１個別固定接点３ａに接触した後、第２個別固定接点３ｂに接触するものとなり、１段目スイッチがオンした後、２段目スイッチがオンするものとなっている。   As shown in FIGS. 2 and 5, the first individual fixed contact 3a, which is a first-stage switch located on the left side when viewed from the opening 1b of the base 1, is a second-stage switch located on the right side. Compared to the second individual fixed contact 3b, the length of the exposed portion on the front end side (opening portion 1b side) in the sliding direction of the movable contact member 6, that is, the sliding movement direction of the slide member 4, is formed slightly longer. Therefore, when the slide member 4 is slid, the movable contact member 6 comes into contact with the first individual fixed contact 3a, and then comes into contact with the second individual fixed contact 3b. The eye switch is turned on.

また、この場合、ガイド溝１ｆの略中央に設けられたクリック用の段差部１ｉは、一方の１段目スイッチである第１個別固定接点３ａが設けられた壁部１ｇ側では、導電部にかかった位置に設けられ、他方の２段目スイッチである第２個別固定接点３ｂが設けられた壁部１ｈ側では、合成樹脂材からなる非導電部に設けられており、このため、スライド部材４のスライド移動時には、可動接点部材６が第１個別固定接点３ａに接触した後、可動接点部材６が段差部１ｉを乗り上げることによりクリック感触が得られ、その後、第２個別固定接点３ｂに接触するものとなっている。   Further, in this case, the click step portion 1i provided in the approximate center of the guide groove 1f is connected to the conductive portion on the wall portion 1g side where the first individual fixed contact 3a which is one of the first step switches is provided. On the wall 1h side provided with the second individual fixed contact 3b, which is the other second-stage switch, is provided in the non-conductive portion made of a synthetic resin material. 4, when the movable contact member 6 comes into contact with the first individual fixed contact 3 a, the movable contact member 6 rides on the stepped portion 1 i to obtain a click feeling, and then contacts the second individual fixed contact 3 b. It is supposed to be.

スライド部材４は、同じく合成樹脂等の絶縁材で形成され、基台１の収納部１ａにスライド移動可能に収容された駆動部４ａと、この駆動部４ａの前方に設けられ、基台１の開口部１ｂから突出された矩形状の操作部４ｂとを有している。また、駆動部４ａは、両側面に設けられ、収納部１ａの内壁面と摺動する一対の摺動腕部４ｃ、４ｃと、これら摺動腕部４ｃ、４ｃより内側に設けられ、可動接点部材６を保持する接点保持部４ｄと、接点保持部４ｄの上面側に突出され、駆動板５をスライド部材４のスライド移動方向に移動可能に係合する矩形状の係合凸部４ｅとを有している。   The slide member 4 is also formed of an insulating material such as synthetic resin, and is provided in front of the drive unit 4a and a drive unit 4a that is slidably accommodated in the storage unit 1a of the base 1. And a rectangular operation portion 4b protruding from the opening 1b. The drive unit 4a is provided on both side surfaces, and is provided inside the pair of sliding arm portions 4c and 4c that slide on the inner wall surface of the storage unit 1a, and the movable contact points 4c and 4c. A contact holding portion 4d that holds the member 6 and a rectangular engagement convex portion 4e that protrudes to the upper surface side of the contact holding portion 4d and engages the drive plate 5 so as to be movable in the sliding movement direction of the slide member 4. Have.

また、接点保持部４ｄの後方側中央には、可動接点部材６を収容する半円状の保持孔部４ｆが設けられており、この保持孔部４ｆの内周面には、基台１の収納部１ａの内底面側に向かって拡開する傾斜面１ｇが設けられている。そして、可動接点部材６が接点保持部４ｄの保持孔部４ｆと駆動板５とによって挟持された時、この傾斜面１ｇにより可動接点部材６を複数の個別固定接点３と摺接する方向に付勢させるものとなっている。   In addition, a semicircular holding hole 4f that accommodates the movable contact member 6 is provided in the center on the rear side of the contact holding part 4d, and an inner peripheral surface of the holding hole 4f is provided on the inner peripheral surface of the base 1. An inclined surface 1g that expands toward the inner bottom surface side of the storage portion 1a is provided. When the movable contact member 6 is sandwiched between the holding hole portion 4f of the contact holding portion 4d and the drive plate 5, the movable contact member 6 is urged in a direction in which the movable contact member 6 slides on the plurality of individual fixed contacts 3 by the inclined surface 1g. It is something to be made.

駆動板５は、導電性の金属板を打ち抜き折り曲げることにより形成されており、平板状で一端側に両翼部５ｂ、５ｂを有する略Ｔ字状の基板部５ａと、この基板部５ａの略中央に設けられた矩形状の係合孔５ｃと、基板部５ａの両翼部５ｂ、５ｂの周縁部から下方に直角に折り曲げられて同一平面上に対向して形成された一対のばね当接部５ｄ、５ｄと、基板部５ａの他端側に下方に直角に折り曲げられて形成された接点押圧部５ｅとを有している。   The drive plate 5 is formed by punching and bending a conductive metal plate. The drive plate 5 is flat and has a substantially T-shaped substrate portion 5a having both wing portions 5b and 5b on one end side, and an approximate center of the substrate portion 5a. And a pair of spring contact portions 5d formed to face each other on the same plane by being bent downward at right angles from the peripheral portions of both wing portions 5b and 5b of the base plate portion 5a. 5d and a contact pressing part 5e formed by bending downward at a right angle on the other end side of the substrate part 5a.

この駆動板５は、スライド部材４の駆動部４ａの上面側に載置され、基板部５ａに設けられた矩形状の係合孔５ｃがスライド部材４の駆動部４ａに設けられた矩形状の係合凸部４ｅに係合されており、スライド部材４のスライド移動に従動して駆動板５がスライド部材４のスライド移動方向に移動可能となっている。この場合、係合孔５ｃは係合凸部４ｅに比べてスライド方向の寸法がやや大きく形成されており、駆動板５がスライド部材４の駆動部４ａ上を独自にスライド移動可能となるように遊嵌された状態となっている。   The drive plate 5 is placed on the upper surface side of the drive unit 4 a of the slide member 4, and a rectangular engagement hole 5 c provided in the substrate unit 5 a is formed in a rectangular shape provided in the drive unit 4 a of the slide member 4. The drive plate 5 is engaged with the engagement convex portion 4 e and is movable in the slide movement direction of the slide member 4 following the slide movement of the slide member 4. In this case, the engagement hole 5c is formed to have a slightly larger dimension in the sliding direction than the engagement convex portion 4e, so that the drive plate 5 can independently slide on the drive portion 4a of the slide member 4. It is in a loosely fitted state.

また、この時、駆動板５の両翼部５ｂ、５ｂに設けられた一対のばね当接部５ｄ、５ｄが、スライド部材４の駆動部４ａの両側面に設けられた一対の摺動腕部４ｃ、４ｃの後方側面に対向あるいは当接した状態で配置され、また、他端側に設けられた接点押圧部５ｅが、接点保持部４ｆの後方中央に設けられた保持孔部４ｆの内周面と対向した状態で配置されている。   At this time, the pair of spring contact portions 5d and 5d provided on both wing portions 5b and 5b of the drive plate 5 are paired with a pair of sliding arm portions 4c provided on both side surfaces of the drive portion 4a of the slide member 4. 4c is arranged in a state of being opposed to or in contact with the rear side surface of 4c, and the contact pressing portion 5e provided on the other end side is an inner peripheral surface of the holding hole portion 4f provided in the rear center of the contact holding portion 4f. It is arranged in a state of facing.

可動接点部材６は、導電性の金属材で球状に形成されている。この可動接点部材６は、自身では弾性を有しておらず、従来の可動接片が自身の撓みによる弾圧力によって摺動時の接点圧を生起させているのに対して、可動接点部材６自身の撓みで接点圧を生起させる必要がないため、金属球等で簡単に形成できるので、小型化が可能となっている。この可動接点部材６は、駆動板５の接点押圧部５ｅとスライド部材４の保持孔部４ｆの内周面に設けられた傾斜面１ｇとの間に挟持されてスライド部材４に従動可能に保持されるものとなっているので、可動接点部材６を球状に形成してもスライド移動時に安定して導通状態を維持することができる。   The movable contact member 6 is formed in a spherical shape with a conductive metal material. The movable contact member 6 does not have elasticity by itself, whereas the conventional movable contact piece generates a contact pressure at the time of sliding due to an elastic force due to its own bending, whereas the movable contact member 6 Since it is not necessary to generate contact pressure by its own bending, it can be easily formed with a metal ball or the like, and thus it can be miniaturized. The movable contact member 6 is sandwiched between a contact pressing portion 5e of the drive plate 5 and an inclined surface 1g provided on the inner peripheral surface of the holding hole portion 4f of the slide member 4, and is held so as to be able to follow the slide member 4. Therefore, even if the movable contact member 6 is formed in a spherical shape, the conductive state can be stably maintained during the sliding movement.

弾性部材７は、導電性の金属線材からなるコイルばねで形成されている。この弾性部材７は、一端側がスライド部材４の駆動部４ａの上面側に載置された駆動板５のばね当接部５ｄに当接され、他端側が基台１の突出部１ｃが設けられた側面の内側面両側に表出した共通固定接点２に当接された状態で、基台１の収納部１ａの内底面に形成された凹溝部１ｅ内に配設されており、駆動部材５と共通固定接点２とが弾性部材７であるコイルばねを介して電気的に導通されている。また、この弾性部材７で、収納部１ａ内にスライド移動可能に収容されたスライド部材４を一方向（図３の右方向）に弾性付勢している。   The elastic member 7 is formed of a coil spring made of a conductive metal wire. One end of the elastic member 7 is in contact with a spring contact portion 5d of the drive plate 5 placed on the upper surface side of the drive portion 4a of the slide member 4, and the other end is provided with a protruding portion 1c of the base 1. The drive member 5 is disposed in a concave groove 1e formed on the inner bottom surface of the storage portion 1a of the base 1 in contact with the common fixed contact 2 exposed on both inner side surfaces of the side surface. And the common fixed contact 2 are electrically connected via a coil spring which is an elastic member 7. Further, the elastic member 7 elastically biases the slide member 4 accommodated in the accommodating portion 1a so as to be slidable in one direction (right direction in FIG. 3).

この場合、弾性部材７は、駆動板５の基板部５ａの両翼部５ｂ、５ｂに設けられた一対のばね当接部５ｄ、５ｄと、基台１の突出部１ｃが設けられた側面の内側面両側に表出した一対の共通固定接点２、２との間に、２個配設されている。すなわち、弾性部材７は、可動接点部材６を中心として対向する位置に一対設けられている。そして、このために、複数の弾性部材７によって可動接点部材６を弾圧することになるので、大きな接点圧が得られると共に、スイッチ内にこれらの弾性部材７をバランス良く配置できることから、可動接点部材６を個別固定接点３と確実に接触させることができるものとなる。   In this case, the elastic member 7 has a pair of spring contact portions 5d and 5d provided on both wing portions 5b and 5b of the base plate portion 5a of the drive plate 5 and a side surface provided with the protruding portion 1c of the base 1. Two pieces are arranged between the pair of common fixed contacts 2 and 2 exposed on both sides of the side surface. That is, a pair of elastic members 7 are provided at positions facing each other with the movable contact member 6 as a center. For this reason, since the movable contact member 6 is elastically pressed by the plurality of elastic members 7, a large contact pressure can be obtained, and these elastic members 7 can be arranged in a balanced manner in the switch. 6 can be reliably brought into contact with the individual fixed contact 3.

また、弾性部材７は、導電性のばね部材から形成して、ばね部材の他端側を共通固定接点２と導通させるようにしたので、共通固定接点２との導通経路をスライド部材４を付勢する弾性部材であるばね部材を兼用して形成できるため、部品点数の削減が図れるものとなっている。   Further, the elastic member 7 is formed of a conductive spring member, and the other end side of the spring member is electrically connected to the common fixed contact 2. Therefore, the slide member 4 is attached to the conductive path with the common fixed contact 2. Since the spring member, which is an elastic member to be energized, can also be formed, the number of parts can be reduced.

また、図３、図４に示すように、弾性部材７が収納部１ａに組み込まれた状態では、弾性部材７の一端側が駆動板５のばね当接部５ｄに当接され、駆動板５がスライド部材４と共にスライド部材４の操作部４ｂが突出する方向へ付勢されており、この時、駆動板５の接点押圧部５ｅと、スライド部材４の保持孔部４ｆの内周面に設けられた傾斜面１ｇとの間に挟持された球状の可動接点部材６は、弾性部材７の弾圧力による接点押圧部５ｅの押圧力（図４の右方向）によって、保持孔部４ｆの傾斜面１ｇに押圧され、この傾斜面１ｇに沿って収納部１ａの内底面側（図４の下方向）へ弾圧されている。   As shown in FIGS. 3 and 4, in a state where the elastic member 7 is incorporated in the storage portion 1 a, one end side of the elastic member 7 is brought into contact with the spring contact portion 5 d of the drive plate 5, and the drive plate 5 is Along with the slide member 4, the operation portion 4 b of the slide member 4 is urged in a protruding direction, and at this time, the contact pressing portion 5 e of the drive plate 5 and the inner peripheral surface of the holding hole portion 4 f of the slide member 4 are provided. The spherical movable contact member 6 sandwiched between the inclined surface 1g and the inclined surface 1g of the holding hole portion 4f by the pressing force of the contact pressing portion 5e due to the elastic force of the elastic member 7 (right direction in FIG. 4). Is pressed to the inner bottom surface side (downward in FIG. 4) of the storage portion 1a along the inclined surface 1g.

このように、球状の可動接点部材６を、弾性部材７の弾圧力により駆動板５の一端側とスライド部材４との間に挟持し、この可動接点部材６を挟持するスライド部材４の当接面に傾斜面１ｇを設けると共に、この傾斜面１ｇにより可動接点部材６を複数の個別固定接点３と摺接する方向に付勢させるようにしたので、簡単な構造で、球状の可動接点部材６を、第１個別固定接点３ａ及び第２個別固定接点３ｂと確実に摺接させることができる。   In this manner, the spherical movable contact member 6 is sandwiched between the one end side of the drive plate 5 and the slide member 4 by the elastic force of the elastic member 7, and the slide member 4 that sandwiches the movable contact member 6 abuts. Since the inclined surface 1g is provided on the surface, and the movable contact member 6 is urged in the sliding contact direction with the plurality of individual fixed contacts 3 by the inclined surface 1g, the spherical movable contact member 6 can be formed with a simple structure. The first individual fixed contact 3a and the second individual fixed contact 3b can be surely brought into sliding contact.

また、収納部１ａの内底面には、スライド部材４のスライド移動方向に沿って延びるガイド溝１ｆを設け、このガイド溝１ｆの両側には、球状の可動接点部材６が跨って摺動する一対の壁部１ｇ、１ｈが設けられており、これら一対の壁部１ｇ、１ｈにそれぞれ第１及び第２個別固定接点３ａ、３ｂを突出させて一体に埋設して形成し、この一対の壁部１ｇ、１ｈ上を球状の可動接点部材６が摺動するものとなっており、可動接点部材６が順次、第１個別固定接点３ａ及び第２個別固定接点３ｂと摺接することから、球状の可動接点部材６を確実に接触させることができるものとなっている。   Further, a guide groove 1f extending along the sliding movement direction of the slide member 4 is provided on the inner bottom surface of the storage portion 1a, and a pair of the spherical movable contact members 6 slide over both sides of the guide groove 1f. The wall portions 1g and 1h are provided, and the pair of wall portions 1g and 1h are formed by projecting the first and second individual fixed contacts 3a and 3b, respectively, and embedding them integrally. The spherical movable contact member 6 slides on 1g and 1h, and the movable contact member 6 sequentially contacts the first individual fixed contact 3a and the second individual fixed contact 3b. The contact member 6 can be reliably brought into contact.

カバー８は、平板状の金属板からなり、略矩形状の蓋部８ａと、対向する両側部の前方側、及び後側部の両端側に、それぞれ下方へ屈曲して設けられた同形の一対の脚部８ｂ、８ｂ、及び８ｂ、８ｂとを有している。また、蓋部８ａにはスライド部材４のスライド方向に延設された略長方形状の膨出部８ｃが設けられ、この膨出部８ｃ内にスライド部材４の矩形状の係合凸部４ｅが移動可能に配置されている。また、それぞれの一対の脚部８ｂ、８ｂは、Ｌ字状の係止爪８ｄ、８ｄを有しており、これら係止爪８ｄ、８ｄが、基台１の開口部１ｂに対向する側面、及び他の対向する側面に同じく突出して設けられた係合突起１ｄと係合することによりカバー８が基台１の収納部１ａの上面側に装着されている。   The cover 8 is made of a flat metal plate, and has a substantially rectangular lid portion 8a, a pair of identical shapes provided on the front side of the opposite side portions and the both end sides of the rear side portion, and bent downward. Leg portions 8b and 8b and 8b and 8b. Further, the lid portion 8a is provided with a substantially rectangular bulging portion 8c extending in the sliding direction of the sliding member 4, and the rectangular engaging convex portion 4e of the sliding member 4 is formed in the bulging portion 8c. It is arranged to be movable. Each of the pair of leg portions 8b, 8b has L-shaped locking claws 8d, 8d, and these locking claws 8d, 8d are side surfaces facing the opening 1b of the base 1, The cover 8 is mounted on the upper surface side of the storage portion 1a of the base 1 by engaging with the engaging protrusions 1d that are also provided so as to protrude on the other opposing side surfaces.

次に、図４乃至図８を用いて本発明のスイッチ装置の動作を説明する。
まず、図４に示す初期状態では、スライド部材４は弾性部材７の弾圧力により駆動板５を介して図示右方向へ付勢されている。この時、球状の可動接点部材６は、弾性部材６の弾圧力により駆動板５を介してスライド部材４の傾斜面１ｇに押圧されて下方に付勢され、接点圧を生起した状態で収納部１ａの内底面に形成されたガイド溝１ｆの両壁部１ｇ、１ｈ上に弾圧されている。この状態では、可動接点部材６は、第１個別固定接点３ａ及び第２個別固定接点３ｂとは離間しておりスイッチはオフ状態となっている。 Next, the operation of the switch device of the present invention will be described with reference to FIGS.
First, in the initial state shown in FIG. 4, the slide member 4 is urged rightward in the drawing via the drive plate 5 by the elastic force of the elastic member 7. At this time, the spherical movable contact member 6 is pressed against the inclined surface 1g of the slide member 4 via the drive plate 5 by the elastic force of the elastic member 6 and is urged downward, and the storage portion is brought into contact with the contact pressure. It is repressed on both wall parts 1g and 1h of the guide groove 1f formed in the inner bottom face of 1a. In this state, the movable contact member 6 is separated from the first individual fixed contact 3a and the second individual fixed contact 3b, and the switch is off.

次に、図７に示すようにスライド部材４を図示左方向へ押圧操作すると、弾性部材７の付勢力に抗してスライド部材４及び駆動板５と可動接点部材６が左方向に移動し、可動接点部材６がガイド溝１ｆの両壁部１ｇ、１ｈ上を摺動して、図５で左側に示す壁部１ｇに表出された第１個別固定接点３ａの前端側に接触して、第１個別可動接点３ａと共通個別固定接点２が可動接点部材６、駆動板５及び弾性部材７を介して電気的に導通され１段目スイッチがオン状態となる。
この時、可動接点部材６は、スライド部材４の押圧操作に伴い圧縮された弾性部材７の更に加圧された弾圧力により第１個別固定接点３ａに弾圧されるので、確実に安定した接点圧が得られるものとなる。 Next, when the slide member 4 is pressed to the left as shown in FIG. 7, the slide member 4, the drive plate 5, and the movable contact member 6 move to the left against the urging force of the elastic member 7, The movable contact member 6 slides on both the wall portions 1g and 1h of the guide groove 1f and comes into contact with the front end side of the first individual fixed contact 3a exposed on the wall portion 1g shown on the left side in FIG. The first individual movable contact 3a and the common individual fixed contact 2 are electrically connected via the movable contact member 6, the drive plate 5, and the elastic member 7, and the first stage switch is turned on.
At this time, the movable contact member 6 is elastically pressed against the first individual fixed contact 3a by the pressurized elastic force of the elastic member 7 compressed in accordance with the pressing operation of the slide member 4, so that a stable contact pressure can be ensured. Is obtained.

次に、この状態から、図８に示すように、更にスライド部材４を図示左方向に押圧操作すると、更に弾性部材７の付勢力に抗してスライド部材４及び駆動板５と可動接点部材６が左方向に移動し、可動接点部材６が壁部１ｇ、１ｈ上を摺動してガイド溝１ｆの略中央に設けられた段差部１ｉ（図５参照）に当接して、可動接点部材６が壁部１ｇ、１ｈの段差を乗り越える時にクリック感触が生起されるものとなる。そして、可動接点部材６が図５で右側に示す壁部１ｈに表出された第２個別固定接点３ｂと接触して、第２個別可動接点３ｂと共通個別固定接点２が可動接点部材６、駆動板５及び弾性部材７を介して電気的に導通され２段目スイッチがオン状態となる。   Next, as shown in FIG. 8, when the slide member 4 is further pressed to the left in this state from this state, the slide member 4, the drive plate 5, and the movable contact member 6 are further resisted against the urging force of the elastic member 7. Moves to the left, and the movable contact member 6 slides on the wall portions 1g and 1h and comes into contact with a step portion 1i (see FIG. 5) provided substantially at the center of the guide groove 1f. A click feeling is generated when the wall climbs over the steps of the walls 1g and 1h. Then, the movable contact member 6 comes into contact with the second individual fixed contact 3b exposed on the wall 1h shown on the right side in FIG. 5, and the second individual movable contact 3b and the common individual fixed contact 2 are moved to the movable contact member 6, The second stage switch is turned on by electrical conduction through the drive plate 5 and the elastic member 7.

この時、球状の可動接点部材６は、段差部１ｉにより壁部１ｇ、１ｈの高さが変わるため、スライド部材４の傾斜面１ｇに沿って上方へ移動することになるが、駆動板５はスライド部材４の駆動部４ａ上を独自にスライド移動可能に遊嵌されているため、可動接点部材６を押圧している駆動板５の接点押圧部５ｅが、スライド部材４のスライド移動方向（図８で左側）へ移動することにより、可動接点部材６は上方への移動が可能となっている。
また、可動接点部材６は、スライド部材４の押圧操作に伴い圧縮された弾性部材７の更に加圧された弾圧力により第２個別固定接点３ｂに弾圧されるので、更に、確実に安定した接点圧が得られるものとなる。 At this time, the spherical movable contact member 6 moves upward along the inclined surface 1g of the slide member 4 because the heights of the wall portions 1g and 1h are changed by the step portion 1i. Since the slide member 4 is loosely fitted so as to be slidable independently on the drive part 4a, the contact pressing part 5e of the drive plate 5 pressing the movable contact member 6 is slid in the sliding direction of the slide member 4 (see FIG. 8 to the left), the movable contact member 6 can be moved upward.
Further, since the movable contact member 6 is elastically pressed against the second individual fixed contact 3b by the pressurized elastic force of the elastic member 7 which is compressed in accordance with the pressing operation of the slide member 4, a more stable and stable contact is achieved. Pressure is obtained.

尚、本実施例では、２段目スイッチのオン時にクリック感触を発生する構造で説明したが、第１個別固定接点３ａの前端側にも同様な段差部を設けて、１段目スイッチのオン時においてもクリック感触が生起されるようにしてもよい。   In this embodiment, the structure is described in which a click feeling is generated when the second stage switch is turned on. However, a similar step portion is provided on the front end side of the first individual fixed contact 3a to turn on the first stage switch. A click feeling may be generated even at times.

上記した本発明の実施例によれば、スライド部材４に、弾性部材７の一端側と当接し、この弾性部材７の付勢方向に移動可能な駆動板５を設けると共に、可動接点部材６を球状に形成し、この可動接点部材６をスライド部材４と駆動板５との間に挟持して、スライド部材４に従動可能に保持し、弾性部材７の弾圧力によって可動接点部材６を個別固定接点３ａ、３ｂと摺接する方向に付勢させて、可動接点部材６を個別固定接点３ａ、３ｂに圧接させるようにしたので、弾性部材７によって可動接点部材６を弾圧することにより、小さな可動接点部材でも接点圧を増加させることができ、球状の可動接点部材６を個別固定接点３ａ、３ｂと確実に摺接でき、接触信頼性の高いスイッチ装置を提供できるものとなっている。   According to the above-described embodiment of the present invention, the slide member 4 is provided with the drive plate 5 that contacts the one end side of the elastic member 7 and is movable in the urging direction of the elastic member 7, and the movable contact member 6 is The movable contact member 6 is formed in a spherical shape, and is held between the slide member 4 and the drive plate 5 so as to be driven by the slide member 4. The movable contact member 6 is individually fixed by the elastic force of the elastic member 7. Since the movable contact member 6 is urged in the sliding contact direction with the contacts 3a and 3b to press-contact the individual fixed contacts 3a and 3b, the movable contact member 6 is elastically pressed by the elastic member 7 so that the small movable contact is obtained. The contact pressure can be increased even with the member, the spherical movable contact member 6 can be slidably contacted with the individual fixed contacts 3a and 3b, and a switch device with high contact reliability can be provided.

尚、上記した本発明の実施例では、個別固定接点をスライド部材の移動方向に複数設け、スライド位置に対応した複数の信号入力を行うスイッチで説明したが、本発明はこのような多段入力を行うものに限定されるものではない。
例えば、個別固定接点３ａのみを形成して、他の個別固定接点３ｂの形成位置には絶縁樹脂を盛って、他の個別固定接点３ｂとその出力端子３ｄとを省くことにより1段スイッチとして構成しても良い。その場合は、個別固定接点３ａに可動接点部材６が当接してスイッチがオン状態に切り替わった後に、更にスライド部材４をスライド移動させることが可能となり、接点部の接点圧を確保すると共に作動力および操作量の大きなスイッチを提供することが可能となる。
また、個別固定接点３ｂのみを設けて１段スイッチを構成する場合には、可動接点部材６が壁部１ｇ、１ｈの段差を乗り越えてクリック感触が発生した後に接点部によるスイッチ切換えを行うことが可能となる。 In the embodiment of the present invention described above, a plurality of individual fixed contacts are provided in the moving direction of the slide member, and a switch for inputting a plurality of signals corresponding to the slide position has been described. However, the present invention provides such a multistage input. You are not limited to what you do.
For example, it is configured as a one-stage switch by forming only the individual fixed contact 3a, placing insulating resin on the position where the other individual fixed contact 3b is formed, and omitting the other individual fixed contact 3b and its output terminal 3d. You may do it. In that case, after the movable contact member 6 comes into contact with the individual fixed contact 3a and the switch is turned on, the slide member 4 can be further slid, and the contact pressure of the contact portion is ensured and the operating force is increased.
