スイッチswitch
　本発明は、照明装置の点灯／消灯の操作に用いて好適なスイッチに関する。 The present invention relates to a switch suitable for use in turning on / off a lighting device.
　従来から、照明装置等の負荷の動作状態を表示する表示用光源を備え、照明装置の点灯／消灯の操作に用いられるスイッチが知られている。この種のスイッチは、通常壁面などの造営面に取り付け枠を介して埋設されている。 2. Description of the Related Art Conventionally, a switch that includes a light source for display that displays an operating state of a load such as a lighting device and is used for turning on / off the lighting device is known. This type of switch is normally embedded in a construction surface such as a wall surface via a mounting frame.
　例えば、日本国特開２００３－２７２４８１号公報には、ピアノハンドル式スイッチにおいて、ＬＥＤ（発光ダイオード）を表示用光源として用いた技術が開示されている。ピアノハンドル式スイッチとは、操作ハンドルとして、ピアノタッチ操作によって押圧されるピアノハンドルが適用されているスイッチである。操作ハンドルは、スイッチ本体の端縁部から突出された支軸によって回動自在に支持され、スイッチ本体に組み込まれている押釦ハンドルに駆動力を伝達する。 For example, Japanese Patent Application Laid-Open No. 2003-272481 discloses a technique using an LED (light emitting diode) as a display light source in a piano handle type switch. The piano handle type switch is a switch to which a piano handle pressed by a piano touch operation is applied as an operation handle. The operation handle is rotatably supported by a support shaft protruding from an end edge portion of the switch body, and transmits a driving force to a push button handle incorporated in the switch body.
　また、日本国特開２０１１－２４３２９５号公報には、縦長形状の操作ハンドルの上下方向に長尺状に形成された点灯表示部にＬＥＤから出力された光を導光する縦長形状の導光体を備えたスイッチが開示されている。 Japanese Patent Application Laid-Open No. 2011-243295 discloses a vertically long light guide that guides light output from an LED to a lighting display portion that is formed in a vertically long shape of a vertically long operation handle. A switch is disclosed.
　従来のピアノハンドル式スイッチにおいて、押釦ハンドルは、支軸とは反対側の端縁部に形成されている。従って、負荷の動作状態を表示する表示用ＬＥＤ及びその出力光を表示する表示部は、押釦ハンドル及び押釦ハンドルによって駆動される反転ハンドル等との干渉を回避して、支軸の近傍に配設されている。操作ハンドルは、支軸を中心として回動する構造であるため、支軸から離れた場所すなわち操作ハンドルの先端領域に操作部が位置する。このため、表示用ＬＥＤの表示部から離れた場所に位置される操作部を操作する必要があり、直感的な操作が困難で使い勝手がよくなかった。 In a conventional piano handle type switch, the push button handle is formed on the edge portion on the opposite side to the support shaft. Therefore, the display LED for displaying the operation state of the load and the display unit for displaying the output light are disposed in the vicinity of the support shaft while avoiding interference with the push button handle and the reversing handle driven by the push button handle. Has been. Since the operation handle has a structure that rotates about the support shaft, the operation unit is located at a position away from the support shaft, that is, in a tip region of the operation handle. For this reason, it is necessary to operate the operation part located in the place away from the display part of LED for a display, and intuitive operation was difficult and was not convenient.
　一方、支軸とは反対側の端縁部に表示用ＬＥＤを配設するために、押釦ハンドルを支軸に接近させて配設し、押釦ハンドルの往復ストロークを従来のスイッチと同等に確保した場合、操作ハンドルのストロークが大きくなり、操作性が悪化する。また、移動量が大きい操作部の近傍に表示用ＬＥＤが位置されるため、表示用ＬＥＤの出力光が操作ハンドルの周辺から漏れやすくなる。 On the other hand, in order to dispose the display LED on the edge opposite to the support shaft, the push button handle is disposed close to the support shaft, and the reciprocating stroke of the push button handle is assured as the conventional switch. In this case, the stroke of the operation handle becomes large and the operability is deteriorated. Further, since the display LED is positioned in the vicinity of the operation unit having a large movement amount, the output light of the display LED is likely to leak from the periphery of the operation handle.
　本発明は、上記課題を解決するためになされたものであり、良好な操作性を維持しつつ、直感的な操作を可能として使い勝手を高めることができるスイッチを提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a switch that can be operated intuitively while maintaining good operability and can be improved in usability.

　本発明の一実施形態によるスイッチについて図面を参照して説明する。図１は同スイッチを用いた照明システムの回路構成を示す。スイッチ１は、白熱灯、蛍光灯又はＬＥＤ電球などの負荷Ｌと交流電源との間に直列接続され、負荷Ｌへの給電を制御する。スイッチ１は、開閉部２と、トランス３と、オン表示用ＬＥＤ（表示用光源）４と、ダイオード５と、抵抗６と、オフ表示用ＬＥＤ（表示用光源）７と、抵抗８、ダイオード９等を備える。 A switch according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a circuit configuration of an illumination system using the switch. The switch 1 is connected in series between a load L such as an incandescent lamp, a fluorescent lamp, or an LED bulb and an AC power supply, and controls power supply to the load L. The switch 1 includes an open / close unit 2, a transformer 3, an on display LED (display light source) 4, a diode 5, a resistor 6, an off display LED (display light source) 7, a resistor 8, and a diode 9. Etc.
　開閉部２は、負荷Ｌ、交流電源、トランス３の１次コイル３ａによって構成される回路に直列接続される。トランス３は、開閉部２の閉成時に１次コイル３ａに入力された交流電流によって励磁して、２次コイル３ｂから交流電流を出力する。オン表示用ＬＥＤ４は、２次コイル３ｂから給電を受けて発光し、負荷Ｌが動作中である旨を表示する。オン表示用ＬＥＤ４としては、例えば、赤色又は橙色のＬＥＤが適用される。ダイオード５は、交流電流に対応するようオン表示用ＬＥＤ４とは逆向きに並列接続される。抵抗６は、２次コイル３ｂとオン表示用ＬＥＤ４との間に直列接続され、オン表示用ＬＥＤ４に流れる電流を制限し、オン表示用ＬＥＤ４の明るさを調整する。オフ表示用ＬＥＤ７は、開閉部２に並列に接続され、開閉部２が開成したとき発光し、負荷Ｌが非動作中である旨を表示する。オフ表示用ＬＥＤ７としては、例えば、緑色又は青色のＬＥＤが適用される。抵抗８は、オフ表示用ＬＥＤ７に直列接続され、オフ表示用ＬＥＤ７に流れる電流を制限する。ダイオード９は、交流電流に対応するようオフ表示用ＬＥＤ７とは逆向きに並列接続される。開閉部２が開成しているとき、負荷Ｌが誤動作（例えば照明装置の場合点灯）することを防止するために、オフ表示用ＬＥＤ７に直列接続されている抵抗８のインピーダンスを大きくしている。また、トランス３の２次コイル３ｂにはほとんど誘導起電力が誘起されないので、オン表示用ＬＥＤ４は点灯しない。 The switching unit 2 is connected in series to a circuit constituted by a load L, an AC power source, and a primary coil 3a of the transformer 3. The transformer 3 is excited by an alternating current input to the primary coil 3a when the switching unit 2 is closed, and outputs an alternating current from the secondary coil 3b. The on-display LED 4 emits light upon receiving power from the secondary coil 3b, and displays that the load L is in operation. As the on display LED 4, for example, a red or orange LED is applied. The diode 5 is connected in parallel in the opposite direction to the on-display LED 4 so as to correspond to an alternating current. The resistor 6 is connected in series between the secondary coil 3 b and the on-display LED 4, limits the current flowing through the on-display LED 4, and adjusts the brightness of the on-display LED 4. The off-display LED 7 is connected in parallel to the opening / closing part 2, emits light when the opening / closing part 2 is opened, and displays that the load L is not operating. For example, a green or blue LED is applied as the off-display LED 7. The resistor 8 is connected in series to the off-display LED 7 and limits the current flowing through the off-display LED 7. The diode 9 is connected in parallel in the opposite direction to the off-display LED 7 so as to correspond to an alternating current. When the opening / closing part 2 is opened, the impedance of the resistor 8 connected in series to the off-display LED 7 is increased in order to prevent the load L from malfunctioning (for example, lighting in the case of a lighting device). Further, since the induced electromotive force is hardly induced in the secondary coil 3b of the transformer 3, the on-display LED 4 is not lit.
　図２はスイッチ１の概略構成を示す。スイッチ１は、ピアノハンドル式スイッチと称され、ピアノタッチ操作によって開閉されるスイッチである。スイッチ１は、スイッチ本体１０と、操作ハンドル１１と、取付枠１２と、化粧プレート１３等によって構成される。操作ハンドル１１は、絶縁性を有する樹脂材料によって形成され、スイッチ本体１０の前面に装着され、ユーザによって操作される。取付枠１２は、例えば、金属板をプレス加工することにより形成され、造営面１００（図３参照）に装着される。取付枠１２の内側にはスイッチ本体１０が取り付けられ、スイッチ本体１０は取付枠１２によって支持される。図２は、２つのスイッチ本体１０及び操作ハンドル１１が取付枠１２に取り付けられた形態を示しているが、スイッチ本体１０及び操作ハンドル１１の個数は１つであっても３つ以上であってもよい。化粧プレート１３は、樹脂材料等により成形され、取付枠１２の前面に装着されてスイッチ１の前面、特に取付枠１２の周辺を装飾する。 FIG. 2 shows a schematic configuration of the switch 1. The switch 1 is called a piano handle type switch, and is a switch that is opened and closed by a piano touch operation. The switch 1 includes a switch body 10, an operation handle 11, a mounting frame 12, a decorative plate 13, and the like. The operation handle 11 is formed of an insulating resin material, is attached to the front surface of the switch body 10, and is operated by a user. The attachment frame 12 is formed, for example, by pressing a metal plate, and is attached to the construction surface 100 (see FIG. 3). A switch body 10 is attached to the inside of the mounting frame 12, and the switch body 10 is supported by the mounting frame 12. FIG. 2 shows a configuration in which two switch bodies 10 and operation handles 11 are attached to the mounting frame 12. However, the number of switch bodies 10 and operation handles 11 is one or three or more. Also good. The decorative plate 13 is formed of a resin material or the like and is mounted on the front surface of the mounting frame 12 to decorate the front surface of the switch 1, particularly the periphery of the mounting frame 12.
　図３はスイッチ１の断面を示す。スイッチ本体１０は、図１に示した開閉部２、トランス３、オン表示用ＬＥＤ４、ダイオード５、抵抗６、オフ表示用ＬＥＤ７、抵抗８、ダイオード９等を有する。本実施形態において、オン表示用ＬＥＤ４には砲弾型のＬＥＤが、オフ表示用ＬＥＤ７にはチップ型のＬＥＤが適用される。オン表示用ＬＥＤ４として適用される砲弾型のＬＥＤは、集光作用により光軸方向に強い光を照射でき、負荷Ｌとしての照明器具が点灯している状況（スイッチ１の周囲が明るい状況）においても、出力光を容易に視認可能である。一方、オフ表示用ＬＥＤ７は、負荷Ｌとしての照明器具が消灯している状況（スイッチ１の周囲が暗い状況）で出力光を視認できればよいため、チップ型のＬＥＤが用いられる。 FIG. 3 shows a cross section of the switch 1. The switch body 10 includes the opening / closing part 2, the transformer 3, the on display LED 4, the diode 5, the resistor 6, the off display LED 7, the resistor 8, the diode 9, and the like shown in FIG. In this embodiment, a bullet-type LED is applied to the on-display LED 4 and a chip-type LED is applied to the off-display LED 7. The bullet-type LED applied as the on-display LED 4 can irradiate strong light in the optical axis direction due to the light collecting action, and the lighting fixture as the load L is lit (a situation where the periphery of the switch 1 is bright). In addition, the output light is easily visible. On the other hand, as the off-display LED 7, a chip-type LED is used because it is only necessary to visually recognize the output light in a situation where the lighting fixture as the load L is turned off (a situation where the periphery of the switch 1 is dark).
　また、スイッチ本体１０は、さらに端子板１４ａ，１４ｂ，１４ｃと、反転ハンドル１５と、押釦ハンドル１６と、回路基板１７と、外周ボディ１８と、カバー１９等を有する。端子板１４ａは、一端が交流電源とスイッチ１を接続する電線１０１と、他端が開閉部２とそれぞれ接続される。電線１０１の先端部は、ばね部材（図示せず）によって付勢され、電線１０１と端子板１４ａとの接続状態が保持される。端子板１４ｂは、一端がトランス３の１次コイル３ａと他端がスイッチ１と負荷Ｌを接続する電線１０２とそれぞれ接続される。電線１０２の先端部も、ばね部材（図示せず）によって付勢され、電線１０２と端子板１４ｂとの接続状態が保持される。端子板１４ｃは、一端がトランス３の１次コイル３ａと他端が開閉部２とそれぞれ接続される。トランス３は、開閉部２の近傍（電線１０１と電線１０２との間）に設けられていてもよい。 The switch body 10 further includes terminal plates 14a, 14b, 14c, a reversing handle 15, a push button handle 16, a circuit board 17, an outer peripheral body 18, a cover 19, and the like. One end of the terminal plate 14 a is connected to the electric wire 101 connecting the AC power source and the switch 1, and the other end is connected to the opening / closing part 2. The tip of the electric wire 101 is urged by a spring member (not shown), and the connection state between the electric wire 101 and the terminal plate 14a is maintained. One end of the terminal plate 14 b is connected to the primary coil 3 a of the transformer 3 and the other end is connected to the electric wire 102 connecting the switch 1 and the load L. The distal end portion of the electric wire 102 is also biased by a spring member (not shown), and the connection state between the electric wire 102 and the terminal plate 14b is maintained. One end of the terminal plate 14 c is connected to the primary coil 3 a of the transformer 3 and the other end is connected to the opening / closing part 2. The transformer 3 may be provided in the vicinity of the opening / closing part 2 (between the electric wire 101 and the electric wire 102).
　反転ハンドル１５は、外周ボディ１８によって回動自在に軸支され、押釦ハンドル１６から入力された往復方向の駆動力を回転方向の駆動力に変換して、開閉部２に伝達する。押釦ハンドル１６は、カバー１９によって往復自在に支持され、操作ハンドル１１から入力された駆動力を反転ハンドル１５に伝達する。 The reversing handle 15 is pivotally supported by the outer peripheral body 18, converts the reciprocating driving force input from the push button handle 16 into a rotating driving force and transmits it to the opening / closing unit 2. The push button handle 16 is reciprocally supported by the cover 19 and transmits the driving force input from the operation handle 11 to the reversing handle 15.
　プリント回路基板１７は、オン表示用ＬＥＤ４、ダイオード５、抵抗６、オフ表示用ＬＥＤ７、抵抗８等を搭載する。プリント回路基板１７に替えて、上記各部品を接続する金属板（リード）をインサート成形したマウント部材であってもよい。この場合、マウント部材は、絶縁性を有する樹脂材料によってブロック状に形成される。オン表示用ＬＥＤ４、オフ表示用ＬＥＤ７は、スイッチ１の前面側に配設される。プリント回路基板１７に実装されるオン表示用ＬＥＤ４、オフ表示用ＬＥＤ７は、それぞれの底面の高さを揃えて基板の表面に載置される。ブロック状のマウント部材が用いられる場合も同様である。オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７から出力される光は、後述する第１導光体４１、第２導光体４２、配光体４３等を透過してスイッチ１の外部から視認され、負荷Ｌの動作を確認できる。オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７は、樹脂材料等の絶縁体から成るマウント部材に実装されていてもよい。 The printed circuit board 17 is equipped with an on-display LED 4, a diode 5, a resistor 6, an off-display LED 7, a resistor 8, and the like. Instead of the printed circuit board 17, a mount member formed by insert molding a metal plate (lead) for connecting each of the above components may be used. In this case, the mount member is formed in a block shape by an insulating resin material. The on display LED 4 and the off display LED 7 are arranged on the front side of the switch 1. The on-display LED 4 and the off-display LED 7 mounted on the printed circuit board 17 are placed on the surface of the board with the heights of the bottom surfaces thereof being aligned. The same applies when a block-shaped mount member is used. Light output from the on-display LED 4 and the off-display LED 7 passes through a first light guide body 41, a second light guide body 42, a light distribution body 43, and the like, which will be described later, and is viewed from the outside of the switch 1, and is loaded. The operation of L can be confirmed. The on display LED 4 and the off display LED 7 may be mounted on a mount member made of an insulator such as a resin material.

　ユーザによって操作ハンドル１１が押圧操作されるたびに、その駆動力が押釦ハンドル１６、反転ハンドル１５に順次伝達され、可動板２１が駆動されて開閉部２が閉開する。その一連動作は、特許文献１等に示されたスイッチと同様であるため、その説明は省略する。 Every time the operation handle 11 is pressed by the user, the driving force is sequentially transmitted to the push button handle 16 and the reversing handle 15, and the movable plate 21 is driven to open and close the opening / closing part 2. Since the series of operations is the same as that of the switch disclosed in Patent Document 1 and the like, the description thereof is omitted.
　スイッチ１は、オン表示用ＬＥＤ４又はオフ表示用ＬＥＤ７の出力光をスイッチ１の外部に出射するための構成として、第１導光体４１、第２導光体４２及び配光体４３を有する。開閉部２の開閉に伴い、オン表示用ＬＥＤ４又はオフ表示用ＬＥＤ７が発光すると、その出力光は、第２導光体４２及び第１導光体４１を順次透過して、配光体４３から出射される。 The switch 1 includes a first light guide 41, a second light guide 42, and a light distribution body 43 as a configuration for emitting the output light of the on-display LED 4 or the off-display LED 7 to the outside of the switch 1.

Emitted.
　図４は、スイッチ本体１０と、スイッチ本体１０の前面に装着される操作ハンドル１１を示す。スイッチ本体１０の筐体は、外周ボディ１８と、カバー１９等によって構成される。外周ボディ１８は、図３に示すように、開閉部２、トランス３、端子板１４ａ，１４ｂ，１４ｃ、反転ハンドル１５、回路基板１７及び第２導光体４２等のスイッチ１を構成する主要な部品を収容する。第２導光体４２は、透孔性を有する樹脂材料等によって形成され、オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光を第１導光体４１に導く。第２導光体４２は、カバー１９の前面に形成されている貫通穴１９ｂに嵌合される。カバー１９には、押釦ハンドル１６が組み込まれる。押釦ハンドル１６は、操作ハンドル１１の操作部１１ｃの側、すなわち、軸受け部１１ｂから離れた側に配設される。このため、操作ハンドル１１のストロークを適正値に設定することができ、良好な操作性が得られる。 FIG. 4 shows the switch body 10 and the operation handle 11 attached to the front surface of the switch body 10. The casing of the switch body 10 includes an outer peripheral body 18 and a cover 19. As shown in FIG. 3, the outer peripheral body 18 is a main component of the switch 1 such as the opening / closing part 2, the transformer 3, the terminal plates 14 a, 14 b, 14 c, the reversing handle 15, the circuit board 17, and the second light guide 42. Accommodates parts. The second light guide 42 is formed of a resin material having a permeability, and guides output light of the on-display LED 4 and the off-display LED 7 to the first light guide 41. The second light guide 42 is fitted into a through hole 19 b formed on the front surface of the cover 19. A push button handle 16 is incorporated in the cover 19. The push button handle 16 is disposed on the operation portion 11c side of the operation handle 11, that is, on the side away from the bearing portion 11b. For this reason, the stroke of the operation handle 11 can be set to an appropriate value, and good operability can be obtained.
　カバー１９は、支軸１９ａと、貫通穴１９ｂを有する。支軸１９ａは、第２導光体４２の近傍でカバー１９の端縁に形成され、操作ハンドル１１の軸受け部１１ｂと嵌合し、操作ハンドル１１を回動自在に支持する。貫通穴１９ｂは、支軸１９ａの近傍でカバー１９の前壁面を貫通する。貫通穴１９ｂには、第２導光体４２が嵌合され、オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光が出射される。 The cover 19 has a support shaft 19a and a through hole 19b. The support shaft 19a is formed on the edge of the cover 19 in the vicinity of the second light guide 42, is fitted to the bearing portion 11b of the operation handle 11, and supports the operation handle 11 so as to be rotatable. The through hole 19b penetrates the front wall surface of the cover 19 in the vicinity of the support shaft 19a. The second light guide 42 is fitted into the through hole 19b, and the output light of the on display LED 4 and the off display LED 7 is emitted.
　操作ハンドル１１は、表示部１１ａと、軸受け部１１ｂ、操作部１１ｃと、第１導光体４１と、配光体４３を有する。表示部１１ａは、軸受け部１１ｂから離れた操作部１１ｃの側に形成される。ここで、軸受け部１１ｂから離れた側とは、軸受け部１１ｂを操作ハンドル１１の基端とすると、操作ハンドル１１の中心部よりも先端の側であり、必ずしも操作ハンドル１１の端縁部である必要はない。表示部１１ａに形成されている貫通穴に配光体４３が嵌合され、配光体４３からオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光が出射される。軸受け部１１ｂは、支軸１９ａに対応して操作ハンドル１１の背面の端縁近傍において、第１導光体４１を挟んで１対形成される。軸受け部１１ｂが支軸１９ａに嵌合されることにより、スイッチ本体１０によって操作ハンドル１１が回動自在に支持される。操作部１１ｃは、ユーザによって押圧操作される部分であり、軸受け部１１ｂから離れた側に設けられる。すなわち、操作部１１ｃを構成する領域の一部に形成されている表示部１１ａの貫通穴に配光体４３が嵌合される。第１導光体４１は、例えば、超音波溶着などの熱溶着によって操作ハンドル１１に接合される。これにより、両者を接合するための固定部材が不要となり、スイッチ１の構成を簡素化できる。第１導光体４１及び配光体４３は、操作ハンドル１１に設けられているので、操作ハンドル１１の回動に伴い、一体的に回動する。 The operation handle 11 includes a display unit 11a, a bearing unit 11b, an operation unit 11c, a first light guide 41, and a light distribution body 43. The display unit 11a is formed on the operation unit 11c side away from the bearing unit 11b. Here, the side away from the bearing portion 11b is the tip side of the center portion of the operation handle 11 and is always the edge portion of the operation handle 11 when the bearing portion 11b is the base end of the operation handle 11. There is no need. The light distribution body 43 is fitted into the through hole formed in the display portion 11a, and output light from the on display LED 4 and the off display LED 7 is emitted from the light distribution body 43. A pair of bearing portions 11b is formed in the vicinity of the edge of the back surface of the operation handle 11 with the first light guide 41 interposed therebetween corresponding to the support shaft 19a. By fitting the bearing portion 11b to the support shaft 19a, the operation handle 11 is rotatably supported by the switch body 10. The operation portion 11c is a portion that is pressed by the user, and is provided on the side away from the bearing portion 11b. That is, the light distribution body 43 is fitted into the through hole of the display unit 11a formed in a part of the region constituting the operation unit 11c. The first light guide 41 is joined to the operation handle 11 by heat welding such as ultrasonic welding. Thereby, the fixing member for joining both becomes unnecessary, and the structure of the switch 1 can be simplified. Since the first light guide body 41 and the light distribution body 43 are provided on the operation handle 11, the first light guide body 41 and the light distribution body 43 rotate integrally with the rotation of the operation handle 11.
　第１導光体４１は、透孔性を有する樹脂材料等によって形成され、操作ハンドル１１の背面に組み込まれる。第１導光体４１は、第２導光体４２から出射されたオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光を導光する軸受け部１１ｂから離れた側、すなわち操作部１１ｃの側に配設された配光体４３に導く。 The first light guide 41 is formed of a resin material having a hole and the like, and is incorporated in the back surface of the operation handle 11. The first light guide 41 is arranged on the side away from the bearing portion 11b that guides the output light of the on display LED 4 and the off display LED 7 emitted from the second light guide 42, that is, on the operation portion 11c side. Guide to the light distribution body 43 provided.
　配光体４３は、第１導光体４１によって導かれたオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光を所望の範囲に配光して出射する。操作部１１ｃを構成する領域に配光体４３が設けられているので、ユーザは配光体４３から出射されたオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光をよりどころとして操作部１１ｃを操作することができる。例えば、暗闇の中でもオフ表示用ＬＥＤ７の出力光を頼りにすれば、容易に操作部１１ｃを操作することができる。 The light distribution body 43 distributes the output light of the on-display LED 4 and the off-display LED 7 guided by the first light guide 41 to a desired range and emits the light. Since the light distribution body 43 is provided in a region constituting the operation section 11c, the user operates the operation section 11c using the output light of the on display LED 4 and the off display LED 7 emitted from the light distribution body 43 as a source. can do. For example, the operation unit 11c can be easily operated by relying on the output light of the off-display LED 7 even in the dark.
　図５は、第１導光体４１を示す。第１導光体４１は、第１入射部４１ａと、第１反射部４１ｂと、第１導光部４１ｃと、第２反射部４１ｄと、第１出射部４１ｅを有する。第１入射部４１ａは、第１導光体４１の一端に設けられ、第２導光体４２から出射されたオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光が入射される。第１反射部４１ｂは、第１入射部４１ａと第１導光部４１ｃとの間に設けられ、第１入射部４１ａから入射された出力光を反射して、光の向きを第１導光部４１ｃすなわち操作部１１ｃの方向に変える。第１導光部４１ｃは、第１反射部４１ｂと第２反射部４１ｄとの間に設けられ、第１反射部４１ｂによって反射された出力光を操作部１１ｃの側に配設されている第２反射部４１ｄまで導く。第２反射部４１ｄは、第１導光部４１ｃと第１出射部４１ｅとの間に設けられ、第１導光部４１ｃから導かれた出力光を反射して、光の向きを第１出射部４１ｅの方向に変える。第１出射部４１ｅは、第１導光体４１の他端に設けられ、第２反射部４１ｄによって反射された出力光を出射する。 FIG. 5 shows the first light guide 41. The first light guide 41 includes a first incident part 41a, a first reflection part 41b, a first light guide part 41c, a second reflection part 41d, and a first emission part 41e. The first incident portion 41 a is provided at one end of the first light guide 41, and the output light of the on-display LED 4 and the off-display LED 7 emitted from the second light guide 42 is incident thereon. The first reflecting portion 41b is provided between the first incident portion 41a and the first light guide portion 41c, reflects the output light incident from the first incident portion 41a, and changes the direction of the light to the first light guide. It changes to the direction of the part 41c, ie, the operation part 11c. The first light guide part 41c is provided between the first reflection part 41b and the second reflection part 41d, and the output light reflected by the first reflection part 41b is disposed on the operation part 11c side. 2 It guides to 41d part. The second reflection part 41d is provided between the first light guide part 41c and the first light emission part 41e, reflects the output light guided from the first light guide part 41c, and changes the direction of the light to the first emission. It changes to the direction of the part 41e. The first emission part 41e is provided at the other end of the first light guide 41 and emits output light reflected by the second reflection part 41d.
　第１導光体４１は、操作ハンドル１１がスイッチ本体１０に装着されたとき、第１入射部４１ａと第２導光体４２の第２出射部４２ｃとが対向するように、操作ハンドル１１に組み込まれる。第１導光部４１ｃにおけるスイッチ１の奥行き方向の厚み寸法Ｔ１は、第１入射部４１ａから第１反射部４１ｂに至る部分のスイッチ１の奥行き方向の厚み寸法Ｔ２よりも小さく設定されている。これにより、操作ハンドル１１と押釦ハンドル１６との隙間に、第１導光部４１ｃを配置でき、操作ハンドル１１が操作されたとき、第１導光部４１ｃがカバー１９等と干渉して操作ハンドル１１の回動を妨げることが防止される。なお、第１導光部４１ｃを介して操作ハンドル１１の操作部１１ｃに付与された駆動力を押釦ハンドル１６に伝達する構成としてもよい。また、第１導光体４１の第１入射部４１ａを第２導光体４２の第２出射部４２ｃに接近させることにより、第２出射部４２ｃから出射された光を効率よく第１入射部４１ａに入射させることができる。また、第２出射部４２ｃから出射された光が操作ハンドル１１の周辺から漏れることを抑制できる。 When the operation handle 11 is attached to the switch body 10, the first light guide 41 is placed on the operation handle 11 so that the first incident portion 41 a and the second emission portion 42 c of the second light guide 42 face each other. Incorporated. The thickness dimension T1 in the depth direction of the switch 1 in the first light guide 41c is set to be smaller than the thickness dimension T2 in the depth direction of the switch 1 in the portion from the first incident part 41a to the first reflecting part 41b. As a result, the first light guide 41c can be disposed in the gap between the operation handle 11 and the push button handle 16, and when the operation handle 11 is operated, the first light guide 41c interferes with the cover 19 and the like. 11 is prevented from obstructing the rotation. In addition, it is good also as a structure which transmits the driving force provided to the operation part 11c of the operation handle 11 to the pushbutton handle 16 via the 1st light guide part 41c. In addition, by making the first incident portion 41a of the first light guide 41 approach the second emission portion 42c of the second light guide 42, the light emitted from the second emission portion 42c is efficiently converted into the first incident portion. It can enter into 41a. Moreover, it can suppress that the light radiate | emitted from the 2nd output part 42c leaks from the periphery of the operation handle 11. FIG.
　図６は、第２導光体４２を示す。第２導光体４２は、第２入射部４２ａと、第２導光部４２ｂと、第２出射部４２ｃを有する。第２入射部４２ａは、先端部の高さの異なるオン表示用ＬＥＤ４（砲弾型ＬＥＤ）及びオフ表示用ＬＥＤ７（チップ型ＬＥＤ）に対応させて段違い（階段状）に形成されている。これにより、第２導光体４２の第２入射部４２ａをオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出射部に接近させて、光源から出射された光を効率よく第２入射部４２ａに入射させることができる。 FIG. 6 shows the second light guide 42. The second light guide 42 includes a second incident part 42a, a second light guide part 42b, and a second emission part 42c. The second incident portion 42a is formed in a step (stepped shape) corresponding to the on display LED 4 (bullet type LED) and the off display LED 7 (chip type LED) having different tip heights. Accordingly, the second incident portion 42a of the second light guide 42 is brought close to the emitting portions of the on-display LED 4 and the off-display LED 7, and the light emitted from the light source is efficiently incident on the second incident portion 42a. be able to.
　また、第１導光体４１の第１反射部４１ｂは、複数の表示用光源のうちいずれかの光源（例えば、オン表示用ＬＥＤ４）の光軸上に配置されている。一方、第１反射部４１ｂはオフ表示用ＬＥＤ７の光軸上に配置されていない。これにより、オン表示用ＬＥＤ４の出力光を明るく、オフ表示用ＬＥＤ７の出力光をほんのりとやわらかく表示することができる。第１反射部４１ｂをオフ表示用ＬＥＤ７の光軸上に配置することにより、オフ表示用ＬＥＤ７も明るく表示することができる。 Further, the first reflecting portion 41b of the first light guide 41 is disposed on the optical axis of any one of the light sources for display (for example, the on-display LED 4). On the other hand, the 1st reflection part 41b is not arrange | positioned on the optical axis of LED7 for off display. Thereby, the output light of the on-display LED 4 can be brightened and the output light of the off-display LED 7 can be displayed slightly softly. By disposing the first reflecting portion 41b on the optical axis of the off-display LED 7, the off-display LED 7 can also be displayed brightly.
　第１導光体４１の第１入射部４１ａが第２導光体４２の第２出射部４２ｃと干渉して操作ハンドル１１の回動を妨げないように、第１入射部４１ａと第２出射部４２ｃとは所定の間隔を隔てて配設されている。本実施形態では、操作ハンドル１１の回動中心となる支軸１９ａの近傍に第１入射部４１ａが位置されるので、操作ハンドル１１の回動に伴う第１入射部４１ａの移動が抑制される。従って、第１入射部４１ａと第２出射部４２ｃとの干渉が発生しにくくなり、第１入射部４１ａと第２出射部４２ｃとの間隔を小さく設定して、第２出射部４２ｃから出射された光を効率よく第１入射部４１ａに入射させることができる。 The first incident portion 41a and the second emission portion are arranged so that the first incidence portion 41a of the first light guide body 41 does not interfere with the second emission portion 42c of the second light guide body 42 and prevent the operation handle 11 from rotating. The part 42c is disposed at a predetermined interval. In the present embodiment, since the first incident portion 41a is located in the vicinity of the support shaft 19a serving as the rotation center of the operation handle 11, the movement of the first incident portion 41a accompanying the rotation of the operation handle 11 is suppressed. . Accordingly, interference between the first incident portion 41a and the second emission portion 42c is less likely to occur, and the interval between the first incidence portion 41a and the second emission portion 42c is set to be small and emitted from the second emission portion 42c. Can efficiently enter the first incident portion 41a.
　図７は、オン表示用ＬＥＤ４の出力光が第２導光体４２及び第１導光体４１によって導かれ、配光体４３から出射される様子を示している。また、図８は、オフ表示用ＬＥＤ７の出力光が第２導光体４２及び第１導光体４１によって導かれ、配光体４３から出射される様子を示している。オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光は、第２導光体４２の端面によって適宜反射されながら、第１導光体４１に入射する。第１導光体４１に入射した出力光は、第１反射部４１ｂ及び第２反射部４１ｄの他第１導光部４１ｃの端面によって適宜反射されながら、配光体４３に入射する。 FIG. 7 shows a state in which the output light of the on-display LED 4 is guided by the second light guide 42 and the first light guide 41 and is emitted from the light distribution body 43. FIG. 8 shows a state in which the output light of the off-display LED 7 is guided by the second light guide 42 and the first light guide 41 and is emitted from the light distribution body 43. The output light of the on display LED 4 and the off display LED 7 is incident on the first light guide 41 while being appropriately reflected by the end surface of the second light guide 42. The output light incident on the first light guide 41 is incident on the light distribution body 43 while being appropriately reflected by the end surfaces of the first light guide 41c in addition to the first reflector 41b and the second reflector 41d.
　第１導光体４１の第１反射部４１ｂは、放物面又は楕円面によって構成されている。第１反射部４１ｂが放物面によって構成されている形態によれば、複数の光源から出射された出力光を効率よく反射して、第１導光部４１ｃに導くことができる。また、第１反射部４１ｂが楕円面によって構成されている形態によれば、複数の光源のうち、一方の光源から出射された出力光を特に効率よく反射して、第１導光部４１ｃに導くことができる。 The first reflecting portion 41b of the first light guide 41 is configured by a paraboloid or an ellipsoid. According to the form in which the first reflecting portion 41b is configured by a paraboloid, output light emitted from a plurality of light sources can be efficiently reflected and guided to the first light guide portion 41c. In addition, according to the form in which the first reflecting portion 41b is configured by an elliptical surface, the output light emitted from one of the plurality of light sources is particularly efficiently reflected to the first light guide portion 41c. Can lead.
　また、配光体４３の表面には、プリズムが形成されている。これにより、配光体４３を透過する光量を低下させることなく、配光体４３の外側からスイッチ１の内部構造が見えにくくなる。また、配光体４３は、例えば、光拡散材を含有する透孔材料によって構成される。これにより、配光体４３の外側からスイッチ１の内部構造が見えにくくなる。また、オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光が配光体４３を透過する際に、光拡散材によって拡散され、均一でぼんやりとしたやわらかい光を出射できるようになる。 Also, a prism is formed on the surface of the light distribution body 43. This makes it difficult to see the internal structure of the switch 1 from the outside of the light distribution body 43 without reducing the amount of light transmitted through the light distribution body 43. Moreover, the light distribution body 43 is comprised by the through-hole material containing a light-diffusion material, for example. Thereby, it becomes difficult to see the internal structure of the switch 1 from the outside of the light distribution body 43. Further, when the output light of the on-display LED 4 and the off-display LED 7 is transmitted through the light distribution body 43, the light is diffused by the light diffusing material, and uniform, faint and soft light can be emitted.
　以上のような構成を有する本実施形態のスイッチ１によれば、オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光は、操作ハンドル１１において光源から離れた操作部１１ｃの側で出射される。これにより、良好な操作性を維持しつつ、直感的な操作を可能として使い勝手を高めることができる。また、移動量の大きい操作部１１ｃから離れた位置にオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７が配置されているので、操作ハンドル１１の周辺からオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光が漏れることが抑制される。 According to the switch 1 of the present embodiment having the above-described configuration, the output light of the on-display LED 4 and the off-display LED 7 is emitted from the operation handle 11 on the side of the operation unit 11c away from the light source. As a result, while maintaining good operability, an intuitive operation can be performed and usability can be improved. Further, since the on display LED 4 and the off display LED 7 are disposed at a position away from the operation unit 11c having a large movement amount, the output light of the on display LED 4 and the off display LED 7 leaks from the periphery of the operation handle 11. It is suppressed.
　また、操作ハンドル１１が、オン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７の出力光を操作部１１ｃの側に導く第１導光体４１を有するので、簡素な構成でありながら、負荷Ｌの動作状態を光源から離れた操作部１１ｃの側で表示できる。 In addition, since the operation handle 11 includes the first light guide 41 that guides the output light of the on-display LED 4 and the off-display LED 7 to the operation unit 11c side, the operating state of the load L can be changed with a simple configuration. The image can be displayed on the side of the operation unit 11c away from the light source.
　回動する第１導光体４１と光源であるオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７との間に第２導光体４２が設けられているので、光源の出力光を効率よく第１導光体４１に導くことができる。 Since the second light guide 42 is provided between the rotating first light guide 41 and the on-display LED 4 and the off-display LED 7 which are light sources, the output light of the light source is efficiently guided to the first light guide. It can be guided to the body 41.
　第１導光体４１は、第１入射部４１ａと、第１反射部４１ｂと、第１導光部４１ｃと、第１出射部４１ｅを有するので、簡素な構成で、光源の出力光の向きを変えながら第１出射部４１ｅに導くことができる。また、第１導光部４１ｃの厚み寸法Ｔ１が、第１入射部４１ａから第１反射部４１ｂに至る部分の厚み寸法Ｔ２よりも小さいので、第１導光部４１ｃがスイッチ本体１０等と干渉して操作ハンドル１１の回動を妨げることが防止される。 Since the first light guide 41 includes the first incident portion 41a, the first reflection portion 41b, the first light guide portion 41c, and the first emission portion 41e, the direction of the output light of the light source is simple. Can be guided to the first emitting part 41e. Moreover, since the thickness dimension T1 of the first light guide 41c is smaller than the thickness dimension T2 of the portion from the first incident part 41a to the first reflection part 41b, the first light guide part 41c interferes with the switch body 10 and the like. Thus, hindering the rotation of the operation handle 11 is prevented.
　表示用光源として、複数種類のＬＥＤ４，７が設けられているので、負荷Ｌの動作状態に応じて、表示部の表示を切り替えることができ、スイッチ１の使い勝手が高められる。 Since a plurality of types of LEDs 4 and 7 are provided as the display light source, the display on the display unit can be switched according to the operating state of the load L, and the usability of the switch 1 is enhanced.
　また、複数種類のＬＥＤ４，７が、回路基板１７にそれぞれ実装されているので、簡素な構成で容易にＬＥＤ４，７を実装でき、スイッチ１のコストダウンを図ることができる。また、第２導光体４２における第２入射部４２ａは、各ＬＥＤ４，７の先端に対応して段違いに形成されているので、第２入射部４２ａを各ＬＥＤ４，７の出射部に接近させて、光源から出射された光を効率よく第２入射部４２ａに入射させることができる。 Further, since a plurality of types of LEDs 4 and 7 are mounted on the circuit board 17, the LEDs 4 and 7 can be easily mounted with a simple configuration, and the cost of the switch 1 can be reduced. Moreover, since the 2nd incident part 42a in the 2nd light guide 42 is formed in steps corresponding to the front-end | tip of each LED4, 7, the 2nd incident part 42a is made to approach the radiation | emission part of each LED4,7. Thus, the light emitted from the light source can be efficiently incident on the second incident portion 42a.
　また、第１導光体４１の第１反射部４１ｂは、放物面又は楕円面によって構成されているので、複数の光源から出射された出力光又は一方の光源から出射された出力光を効率よく反射して、第１導光部４１ｃに導くことができる。 Moreover, since the 1st reflection part 41b of the 1st light guide 41 is comprised by the paraboloid or the elliptical surface, the output light radiate | emitted from the several light source or the output light radiate | emitted from one light source is efficient. It can be reflected well and guided to the first light guide 41c.
　また、第１導光体４１の第１反射部４１ｂは、オン表示用ＬＥＤ４の光軸上に配置されているので、オン表示用ＬＥＤ４の出力光を明るく表示することができる。一方、第１反射部４１ｂはオフ表示用ＬＥＤ７の光軸上に配置されていないので、オフ表示用ＬＥＤ７の出力光をほんのりとやわらかく表示することができる。このように、いずれかの光源の光軸上に第１反射部４１ｂを配置することにより、その光源の出力光を明るく表示することができる。また、オフ表示用ＬＥＤ７の光軸上にも第１反射部４１ｂを配置することにより、オフ表示用ＬＥＤ７も明るく表示することができる。 Further, since the first reflecting portion 41b of the first light guide 41 is disposed on the optical axis of the on-display LED 4, the output light of the on-display LED 4 can be displayed brightly. On the other hand, since the first reflecting portion 41b is not arranged on the optical axis of the off display LED 7, the output light of the off display LED 7 can be displayed slightly softly. As described above, by arranging the first reflecting portion 41b on the optical axis of any one of the light sources, the output light of the light source can be displayed brightly. Further, by disposing the first reflecting portion 41b on the optical axis of the off-display LED 7, the off-display LED 7 can also be displayed brightly.
　また、操作ハンドル１１が、配光体４３を有するので、ＬＥＤ４，７の出力光を所望の範囲に配光して出射することができ、スイッチ１の使い勝手が高められる。また、配光体４３の表面には、プリズムが形成されているので、配光体４３を透過する光量を低下させることなく、配光体４３の外側からスイッチ１の内部構造が見えにくくなり、スイッチ１の商品価値が高まる。また、配光体４３は、光拡散材を含有する透孔材料によって構成されているので、配光体４３の外側からスイッチ１の内部構造が見えにくくなる。また、ＬＥＤ４，７の出力光が配光体４３を透過する際に、光拡散材によって拡散され、均一でぼんやりとしたやわらかい光を出射できるようになり、スイッチ１の商品価値が高まる。 Further, since the operation handle 11 has the light distribution body 43, the output light of the LEDs 4 and 7 can be distributed and emitted within a desired range, and the usability of the switch 1 is improved. In addition, since the prism is formed on the surface of the light distribution body 43, the internal structure of the switch 1 becomes difficult to see from the outside of the light distribution body 43 without reducing the amount of light transmitted through the light distribution body 43. The product value of the switch 1 is increased. Moreover, since the light distribution body 43 is comprised by the through-hole material containing a light-diffusion material, it becomes difficult to see the internal structure of the switch 1 from the outer side of the light distribution body 43. FIG. Moreover, when the output light of LED4, 7 permeate | transmits the light distribution body 43, it will be spread | diffused by the light-diffusion material, and it will become possible to radiate | emit uniform and faint soft light, and the commercial value of switch 1 increases.
　なお、本発明は上記実施形態の構成に限られることはない。少なくとも操作ハンドル１１が、ＬＥＤ４，７の側でスイッチ本体１０によって回動自在に支持され、ＬＥＤ４，７の出力光は、操作ハンドル１１においてＬＥＤ４，７から離れた操作部１１ｃの側で出射されるように構成されていればよい。 The present invention is not limited to the configuration of the above embodiment. At least the operation handle 11 is rotatably supported by the switch body 10 on the LED 4, 7 side, and the output light of the LED 4, 7 is emitted on the operation portion 11 c side away from the LED 4, 7 in the operation handle 11. What is necessary is just to be comprised.
　また、本発明は種々の変形が可能である。例えば、表示用光源として用いられるオン表示用ＬＥＤ４及びオフ表示用ＬＥＤ７は、砲弾型及びチップ型のＬＥＤに限られず、他の形態のＬＥＤであってもよい。さらに、この表示用光源は、ＬＥＤに限られず、ネオンランプ、有機ＥＬ（Electro-Luminescence）等の光源であってもよい。 Further, the present invention can be variously modified. For example, the on-display LED 4 and the off-display LED 7 used as the display light source are not limited to the bullet-type and chip-type LEDs, and may be other types of LEDs. Furthermore, the light source for display is not limited to the LED, and may be a light source such as a neon lamp or an organic EL (Electro-Luminescence).
　また、表示用光源が第１導光体４１の第１入射部４１ａに対向するように近接配置されて、第２導光体４２が廃されていてもよい。また、第１導光体４１と配光体４３が一体に形成されていてもよい。 Further, the second light guide 42 may be discarded by arranging the display light source so as to face the first incident portion 41a of the first light guide 41. Moreover, the 1st light guide 41 and the light distribution body 43 may be formed integrally.
　また、負荷Ｌは、白熱灯、蛍光灯又はＬＥＤ電球などの照明器具に限られず、他の電気器具であってもよい。また、スイッチ本体１０は、外周ボディ１８と、カバー１９によって構成される形態に限られず、他の部品によって置換された形態又は他の部品を追加した形態であってもよい。 Further, the load L is not limited to a lighting fixture such as an incandescent lamp, a fluorescent lamp, or an LED bulb, and may be another electric appliance. Further, the switch body 10 is not limited to the form constituted by the outer peripheral body 18 and the cover 19, but may be a form replaced with other parts or a form added with other parts.
