Abstract

The present invention addresses the problem of providing a method capable of meeting a request for using a rocker switch for various purposes by shortening the entire size of the rocker switch, and improving the stability of an energized state by increasing a contact force at the contact of the rocker switch. In order to solve this problem, coil springs 12 repeatedly undergo compression or releasing in accordance with a pressing operation. A fitting part 112 is provided to a button 11 so as to fit one end of each of the coil springs 12. A load piece 131 is provided to a movable contact piece 13, is fitted to the other end of each of the coil springs 12, and transmits elastic energy generated by compression or releasing of the coil springs 12 to the movable contact piece 13. The movable contact piece 13 oscillates by using the transmitted elastic energy while a contact point serves as a support point S while the contact point is moved.

Description

スイッチ装置Switch device
 本発明は、スイッチ装置に関する。 The present invention relates to a switch device.
 操作ボタンの両端をシーソーのように交互に押下することで電気回路の接続状態と遮断状態との切り替えを行うスイッチは、ロッカスイッチとも呼ばれ、屋内外を問わず多く利用されている。
 従来からあるロッカスイッチには、コイルバネの弾性エネルギーを利用して、ハウジングに固定された受部を支点として可動接片を搖動させるもの(特許文献1)や、搖動自在な滑動部を可動接片上で滑動させるもの(特許文献2)がある。
A switch that switches between the connection state and the cutoff state of the electric circuit by alternately pressing both ends of the operation button like a seesaw is also called a rocker switch, and is widely used both indoors and outdoors.
Conventional rocker switches use the elastic energy of a coil spring to swing a movable contact piece with a receiving portion fixed to a housing as a fulcrum (Patent Literature 1), and a swingable sliding portion on a movable contact piece. (Patent Document 2).
特開2012-074301号公報JP 2012-074301 A 特開2018-125205号公報JP 2018-125205 A
 ロッカスイッチは、様々な用途に利用されるため、用途に応じてスイッチの高さを低くしたいとする要望もある。しかしながら、特許文献1に記載されたスイッチ装置(ロッカスイッチ)は、上述したように支点がハウジングに固定された状態で可動接片が搖動する構成となっている。このため、可動接片を搖動自在とするべく長いコイルバネを採用する必要があり、用途に応じてロッカスイッチを低背化させたいとする要望に応えることが困難であった。
 またさらに、コイルバネは、長ければ長いほど可動接片に加わる荷重が小さくなるので、それに伴い、可動接片が接触端子に接触する際の接触力が小さくなる。そうすると、通電状態の安定性が損なわれるおそれもある。このため、可動接片が接触端子に接触する際の接触力を大きくしたいという要望があった。
Since rocker switches are used for various purposes, there is also a demand for reducing the height of the switch according to the purpose. However, the switch device (rocker switch) described in Patent Literature 1 has a configuration in which the movable contact piece swings with the fulcrum fixed to the housing as described above. For this reason, it is necessary to employ a long coil spring so that the movable contact piece can swing freely, and it has been difficult to meet the demand for reducing the height of the rocker switch according to the application.
Furthermore, since the load applied to the movable contact piece decreases as the length of the coil spring increases, the contact force when the movable contact piece contacts the contact terminal decreases accordingly. Then, the stability of the energized state may be impaired. For this reason, there has been a demand for increasing the contact force when the movable contact piece contacts the contact terminal.
 また、特許文献2に記載されたロッカスイッチは、搖動自在な滑動部を可動接片上で滑動させるスイッチ構造とすることで、ロッカスイッチの低背化を実現させている。しかしながら、特許文献2に記載されたロッカスイッチは、支点となる受部と荷重点との距離が比較的短いので、ロッカスイッチの接点における接触力を強くするためには、荷重点に対し比較的大きな力を加える必要がある。 The rocker switch described in Patent Document 2 has a switch structure in which a swingable sliding portion slides on a movable contact piece, thereby realizing a low-profile rocker switch. However, the rocker switch described in Patent Literature 2 has a relatively short distance between the receiving portion serving as a fulcrum and the load point. You need to apply great force.
 本発明は、このような状況に鑑みてなされたものであり、ロッカスイッチ全体のサイズを短小化させて、様々な用途にロッカスイッチを利用したいとする要望に応えるとともに、ロッカスイッチの接点における接触力を強くして、通電状態の安定性を高めることができる手法を提供することを目的とする。 The present invention has been made in view of such circumstances, and has been made to reduce the size of the entire rocker switch, respond to a demand for using the rocker switch for various applications, and provide a contact at a contact of the rocker switch. It is an object of the present invention to provide a method capable of increasing the power and improving the stability of the energized state.

[First Embodiment]
(Basic configuration)
In the rocker switch 1 according to the first embodiment of the present invention, when the coil spring is compressed or released, the point at which the movable contact piece 13 and the receiving portion 141 come into contact with each other is set as the fulcrum S, and the movable contact point S is moved while moving. The piece 13 is rocked. Specifically, when the rocker switch 1 in the cut-off state is pressed to make the energized state, the fulcrum S becomes the fulcrum S1 shown in FIG. 3A, the fulcrum S2 shown in FIG. 3B, and the fulcrum S2 shown in FIG. The fulcrum S3 shown in FIG. 4B and the fulcrum S5 shown in FIG. 5 move in this order. In addition, when the rocker switch 1 in the energized state is pressed down so as to be in the cutoff state, the fulcrum S is the fulcrum S5 shown in FIG. 5, the fulcrum S4 shown in FIG. 4B, and the fulcrum S3 shown in FIG. 4A. , The fulcrum S2 shown in FIG. 3B and the fulcrum S1 shown in FIG. 3A.
That is, when the rocker switch 1 is depressed to turn on the rocker switch 1 in the cut-off state, the rocker switch 1 is moved from the fulcrum S1 to the receiving portion 141 formed on the upper surface of the common terminal 14. When the movable contact piece 13 swings while moving the position of the fulcrum S in the order of S5, and when a pressing operation is performed to make the movable state into the blocking state, the movable fulcrum 13 is moved while moving the position of the fulcrum S in the reverse order. This is a rocker switch having the characteristic that the contact piece 13 swings.
The rocker switch 1 is configured to include a button 11, a coil spring 12, a movable contact piece 13, a common terminal 14, a contact terminal 15, and a housing 16, as shown in FIGS. .
 以下、ロッカスイッチ1の各構成要素について詳しく説明する。 Hereinafter, each component of the rocker switch 1 will be described in detail.
 (ボタン)
 ボタン11は、ロッカスイッチ1に対する操作を受け付けるためのボタンであり、軸111を回転軸として搖動可能とするボタンである。軸111は、ハウジング16の軸受161によって軸支されている。
 具体的には、ボタン11は、ロッカスイッチ1を遮断状態から通電状態にするための押下操作(以下、「通電操作」と呼ぶ)と、通電状態から遮断状態にするための押下操作(以下、「遮断操作」と呼ぶ)とを受け付ける。
 ボタン11に対する押下操作のうち、通電操作が行われる場合と、遮断操作が行われる場合とで押下される位置が異なる。例えば図3Aに示すように遮断状態にあるロッカスイッチ1に対して通電操作が行われる場合には、ボタン11の中央部よりも左側が押下される。また例えば図5に示すように通電状態にあるロッカスイッチ1に対して遮断操作が行われる場合には、ボタン11の中央部よりも右側が押下される。ボタン11の中央部よりも左側が押下されると、ボタン11は、軸111を回転軸として左回りに回転するように搖動し、ハウジング16に係止される。ボタン11の中央部よりも右側が押下されると、ボタン11は、軸111を回転軸として右回りに回転するように搖動し、ハウジング16に係止される。
 ボタン11に対する押下操作がなされると、コイルバネ12が圧縮又は開放し、その圧縮又は開放により生じる弾性エネルギーを利用して可動接片13が搖動する。
(button)
The button 11 is a button for receiving an operation on the rocker switch 1, and is a button that can swing about the shaft 111 as a rotation axis. The shaft 111 is supported by a bearing 161 of the housing 16.
Specifically, the button 11 is depressed to change the rocker switch 1 from the cut-off state to the energized state (hereinafter, referred to as “energizing operation”), and is depressed to change the rocker switch 1 from the energized state to the cut-off state (hereinafter, referred to as “operation”). (Referred to as “interruption operation”).
Of the pressing operations on the button 11, the pressed positions are different between when the energizing operation is performed and when the shutoff operation is performed. For example, when the energizing operation is performed on the rocker switch 1 in the cutoff state as shown in FIG. 3A, the left side of the button 11 is pressed down from the center. Further, for example, when the shut-off operation is performed on the rocker switch 1 in the energized state as shown in FIG. 5, the right side of the button 11 is depressed. When the left side of the button 11 is pressed down from the center, the button 11 swings so as to rotate counterclockwise about the shaft 111 as a rotation axis, and is locked to the housing 16. When the right side of the button 11 is pressed down, the button 11 swings so as to rotate clockwise about the shaft 111 as a rotation axis, and is locked to the housing 16.
When the button 11 is pressed, the coil spring 12 is compressed or released, and the movable contact piece 13 swings using elastic energy generated by the compression or release.
 (コイルバネ)
 コイルバネ12は、図3A~図5に示すように、一方の端部が、ボタン11の嵌合部112に嵌合され、他方の端部が、可動接片13の荷重片131に嵌合されたコイルバネである。コイルバネ12は、図3A~図5に示すように、ボタン11に対する押下操作を受けると圧縮又は開放を繰り返す。圧縮又は開放により生じた弾性エネルギーは、可動接片13に伝達されることで可動接片13が搖動する。
 なお、スイッチ構造の見やすさの見地から、コイルバネ12の外観の表示は図1のみとし、図3A~図5では、コイルバネ12の位置や動きを示す中心軸のみを破線で表示している。
(Coil spring)
As shown in FIGS. 3A to 5, the coil spring 12 has one end fitted to the fitting portion 112 of the button 11 and the other end fitted to the load piece 131 of the movable contact piece 13. Coil spring. As shown in FIGS. 3A to 5, the coil spring 12 repeatedly compresses or opens when it receives a pressing operation on the button 11. The elastic energy generated by the compression or release is transmitted to the movable contact 13, so that the movable contact 13 swings.
In addition, from the viewpoint of the visibility of the switch structure, only the appearance of the coil spring 12 is shown in FIG. 1, and only the center axis indicating the position and movement of the coil spring 12 is shown in broken lines in FIGS. 3A to 5.
 (可動接片)
 可動接片13は、コイルバネ12の圧縮又は開放により生じる弾性エネルギーを利用して搖動する接片であり、荷重片131と、接触片132と、端部133と、底部134とを含むように構成されている。可動接片13は、共通端子14の上面に形成された受け部141において、支点Sの位置を移動させながら搖動する。
 荷重片131は、コイルバネ12に嵌合される部材であり、コイルバネ12に嵌合された荷重片131の端部は、可動接片13がコイルバネ12の圧縮又は開放により生じた弾性エネルギーを利用して搖動する際の荷重点LPとなる。
 ここで、本発明に係るロッカスイッチ1における荷重点LPと支点Sとの距離は、長ければ長い方ほど、梃の原理によって荷重点LPに加える力が小さくて済む。このため、荷重点LPと支点Sとの距離については、図3A等に示すように、荷重片131の長さの分だけ確保することができる。その結果、短いコイルバネ12を採用することでロッカスイッチ1の低背化を図った場合であっても、接点Pにおいて十分な接触力を確保することができる。
 接触片132は、接触端子15の接触片151と接点Pで接触することで、ロッカスイッチ1を通電状態にするための部材である。
 端部133は、接触片132とは反対側の端部のことをいう。端部133は、ロッカスイッチ1が遮断状態のときはハウジング16により係止された状態となるが、ロッカスイッチ1が通電状態のときはハウジング16から離隔した状態となる。
 底部134は、共通端子14の上面に形成される受部141のいずれかの位置に対し、点又は面で接触している部位である。ボタン11に対する押下操作が行われると、底部134と受部141との接触部分が、可動接片13が搖動する際の支点Sとなる。
(Movable contact)
The movable contact piece 13 is a contact piece that swings using elastic energy generated by compression or release of the coil spring 12, and is configured to include a load piece 131, a contact piece 132, an end 133, and a bottom 134. Have been. The movable contact piece 13 swings while moving the position of the fulcrum S in the receiving portion 141 formed on the upper surface of the common terminal 14.
The load piece 131 is a member fitted to the coil spring 12. The end of the load piece 131 fitted to the coil spring 12 uses elastic energy generated by the movable contact piece 13 by compression or release of the coil spring 12. Point LP when swinging.
Here, the longer the distance between the load point LP and the fulcrum S in the rocker switch 1 according to the present invention, the smaller the force applied to the load point LP by the lever principle. For this reason, the distance between the load point LP and the fulcrum S can be ensured by the length of the load piece 131 as shown in FIG. 3A and the like. As a result, even when the height of the rocker switch 1 is reduced by employing the short coil spring 12, a sufficient contact force can be secured at the contact point P.
The contact piece 132 is a member for bringing the rocker switch 1 into an energized state by making contact with the contact piece 151 of the contact terminal 15 at the contact point P.
The end 133 refers to an end opposite to the contact piece 132. The end portion 133 is locked by the housing 16 when the rocker switch 1 is in the cut-off state, but is separated from the housing 16 when the rocker switch 1 is in the energized state.
The bottom portion 134 is a portion that is in point or surface contact with any position of the receiving portion 141 formed on the upper surface of the common terminal 14. When the pressing operation on the button 11 is performed, the contact portion between the bottom portion 134 and the receiving portion 141 becomes a fulcrum S when the movable contact piece 13 swings.
 可動接片13は、ボタン11に対する通電操作が行われると搖動し、接触端子15に接触する。これによりロッカスイッチ1は通電状態となる。また、可動接片13は、ボタン11に対する遮断操作が行われると、通電操作が行われたときとは逆回転で搖動し、接触片151から離隔する。これによりロッカスイッチ1は遮断状態となる。
 具体的には、可動接片13は、ボタン11に対する遮断操作が行われた後は、図3Aに示すように、接触端子15と離隔し、端部133がハウジング16に係止されて静止した状態となる。
The movable contact piece 13 swings when a power supply operation is performed on the button 11, and comes into contact with the contact terminal 15. As a result, the rocker switch 1 is turned on. In addition, when the shutoff operation on the button 11 is performed, the movable contact piece 13 swings in a reverse rotation to that when the energizing operation is performed, and separates from the contact piece 151. As a result, the rocker switch 1 is turned off.
Specifically, after the operation of shutting off the button 11 is performed, the movable contact piece 13 is separated from the contact terminal 15 as shown in FIG. State.
 ここで、ボタン11に対する通電操作が行われると、可動接片13は、図3B、図4A、図4Bの順で示すように、ハウジング16から端部133を離隔させるとともに、受部141上の支点Sを接触端子15側(図面における右方向)に移動させながら搖動する。
 つまり、共通端子14は、所定の厚みを有するため、共通端子14の上面が、可動接片13と接触する受部141を形成することとなる。可動接片13は、共通端子14の上面に形成された受部141の面に沿って、接触する部分(すなわち支点S)を移動させながら搖動する。
Here, when the energizing operation on the button 11 is performed, the movable contact piece 13 separates the end portion 133 from the housing 16 as shown in FIG. 3B, FIG. 4A, and FIG. It swings while moving the fulcrum S toward the contact terminal 15 (to the right in the drawing).
That is, since the common terminal 14 has a predetermined thickness, the upper surface of the common terminal 14 forms the receiving portion 141 that comes into contact with the movable contact piece 13. The movable contact piece 13 swings along the surface of the receiving portion 141 formed on the upper surface of the common terminal 14 while moving the contact portion (that is, the fulcrum S).
 搖動した可動接片13は、図5に示すように、接触端子15に係止されることで静止する。このとき、可動接片13の接触片132が、接触端子15の接触片151に接触して通電状態となるが、可動接片13には、コイルバネ12の圧縮又は開放により生じた強い弾性エネルギーが加えられている。このため、接触片132は、通電状態の安定性を十分に確保できる接力で接触片151に押圧された状態になる。 可 動 The movable contact piece 13 that has swung is stopped by being locked to the contact terminal 15 as shown in FIG. At this time, the contact piece 132 of the movable contact 13 comes into contact with the contact piece 151 of the contact terminal 15 to be in an energized state. Have been added. For this reason, the contact piece 132 is pressed by the contact piece 151 with a contact force that can sufficiently secure the stability of the energized state.
 ここで、ボタン11に対する遮断操作が行われると、可動接片13は、図4B、図4A、図3Bの順で示すように、接触片151から接触片132を離隔させるとともに、受部141上の支点Sを接触端子15とは反対側(図面における左方向)に移動させながら搖動する。
 搖動した可動接片13は、上述した図3Aに示すように、ハウジング16に端部133を係止されることで静止する。このとき、可動接片13の接触片132は、接触端子15の接触片151と離隔した状態となるので、ロッカスイッチ1は遮断状態となる。
Here, when the shut-off operation is performed on the button 11, the movable contact piece 13 separates the contact piece 132 from the contact piece 151 as shown in FIG. 4B, FIG. 4A, and FIG. Swings while moving the fulcrum S on the side opposite to the contact terminal 15 (to the left in the drawing).
The swingable movable contact piece 13 stops as the end portion 133 is locked to the housing 16 as shown in FIG. 3A described above. At this time, since the contact piece 132 of the movable contact piece 13 is separated from the contact piece 151 of the contact terminal 15, the rocker switch 1 is turned off.
 (共通端子)
 共通端子14は、上面が、可動接片13と接触する部分となる受部141を形成しており、他方の端部が、ハウジング16に固定されている端子である。上面が受部141を形成しているので、上述したように、可動接片13は、共通端子14の受部141の面に沿って、接触する部分(すなわち支点S)を移動させながら搖動する。
(Common terminal)
The common terminal 14 is a terminal whose upper surface forms a receiving portion 141 that is to be in contact with the movable contact piece 13, and whose other end is fixed to the housing 16. Since the upper surface forms the receiving portion 141, as described above, the movable contact piece 13 swings along the surface of the receiving portion 141 of the common terminal 14 while moving the contacting portion (that is, the fulcrum S). .
 (接触端子)
 接触端子15は、一方の端部に接触片151を有し、他方の端部がハウジング16に固定されている端子である。
 ボタン11に対する通電操作が行われると、可動接片13が搖動し、接触片151が可動接片13の接触片132を係止する。これにより、接触片151と接触片132とが接点Pで接触した状態となるため、ロッカスイッチ1が通電状態になる。
 そして、ボタン11に対する遮断操作が行われると、可動接片13が搖動し、接触片151から接触片132が離隔する。これにより、接触片151と接触片132とが接触していない状態となるため、ロッカスイッチ1が遮断状態になる。
(Contact terminal)
The contact terminal 15 is a terminal having a contact piece 151 at one end and having the other end fixed to the housing 16.
When an energizing operation is performed on the button 11, the movable contact piece 13 swings, and the contact piece 151 locks the contact piece 132 of the movable contact piece 13. Accordingly, the contact piece 151 and the contact piece 132 come into contact with each other at the contact point P, so that the rocker switch 1 is turned on.
When the shutoff operation is performed on the button 11, the movable contact piece 13 swings, and the contact piece 132 is separated from the contact piece 151. As a result, the contact piece 151 and the contact piece 132 are not in contact with each other, and the rocker switch 1 is turned off.
 (ハウジング)
 ハウジング16は、中心部に、ボタン11と、コイルバネ12と、可動接片13と、共通端子14と、接触端子15とを配置させるための空洞Hを有する箱状のハウジングであり、ロッカスイッチ1を構成する部材を直接的又は間接的に支持する。ハウジング16には、ボタン11の軸111を軸支する軸受161が設けられている。
(housing)
The housing 16 is a box-shaped housing having a hollow H in which a button 11, a coil spring 12, a movable contact piece 13, a common terminal 14, and a contact terminal 15 are arranged at the center. Is supported directly or indirectly. The housing 16 is provided with a bearing 161 that supports the shaft 111 of the button 11.
 ロッカスイッチ1は、以上の構成を有することにより、ロッカスイッチ1全体のサイズを短小化させて、様々な用途にロッカスイッチ1を利用したいとする要望に応えるとともに、ロッカスイッチ1の接点における接触力を強くして、通電状態の安定性を高めることが可能となる。 Since the rocker switch 1 has the above configuration, the overall size of the rocker switch 1 can be reduced to meet the demand for using the rocker switch 1 for various applications, and the contact force at the contacts of the rocker switch 1 can be improved. And the stability of the energized state can be increased.
 [第2実施形態]
 (基本構成)
 本発明の第2実施形態に係るロッカスイッチ2は、図6に示すように、第1実施形態と同様に、コイルバネ12が圧縮又は開放する際、可動接片23と受部141とが接触する部分を支点Sとし、支点Sの位置を移動させながら搖動する。すなわち、ロッカスイッチ2は、共通端子14の上面に形成された受け部141において、支点Sの位置を移動させながら可動接片23が搖動する、という特徴を有するロッカスイッチである。
 ロッカスイッチ2は、図6に示すように、ボタン21と、コイルバネ12と、可動接片23と、共通端子14と、接触端子15と、ハウジング16とを含むように構成されている。
[Second embodiment]
(Basic configuration)
In the rocker switch 2 according to the second embodiment of the present invention, as shown in FIG. 6, when the coil spring 12 is compressed or released, the movable contact piece 23 comes into contact with the receiving portion 141 as in the first embodiment. The portion is set as a fulcrum S, and swings while moving the position of the fulcrum S. That is, the rocker switch 2 is a rocker switch having a characteristic that the movable contact piece 23 swings while moving the position of the fulcrum S in the receiving portion 141 formed on the upper surface of the common terminal 14.
As shown in FIG. 6, the rocker switch 2 is configured to include a button 21, a coil spring 12, a movable contact piece 23, a common terminal 14, a contact terminal 15, and a housing 16.
 以下、ロッカスイッチ2の各構成要素について詳しく説明する。なお、コイルバネ12、共通端子14、接触端子15、及びハウジング16については、第1実施形態と同様又は略同様の構成となっているため、説明を省略する。 Hereinafter, each component of the rocker switch 2 will be described in detail. Note that the coil spring 12, the common terminal 14, the contact terminal 15, and the housing 16 have the same or substantially the same configuration as the first embodiment, and a description thereof will be omitted.
 (ボタン)
 ボタン21は、ロッカスイッチ2に対する操作を受け付けるためのボタンであり、軸211を回転軸として搖動可能とするボタンである。軸211は、ハウジング16の軸受161によって軸支されている。また、嵌合部212には、コイルバネ12が嵌合されている。
(button)
The button 21 is a button for receiving an operation on the rocker switch 2 and is a button that can swing about the shaft 211 as a rotation axis. The shaft 211 is supported by a bearing 161 of the housing 16. The coil spring 12 is fitted in the fitting portion 212.
 ボタン21は、搖動片213を有する。搖動片213は、ボタン11に対する押下操作に応じて、軸211を回転軸として搖動する。搖動片213の近傍には、可動接片23の第2荷重片235a及び235bが接するか又は僅かな隙間を隔てた状態で配置されている。このため、例えば搖動片213が接触端子15から離れる方向(すなわち、図面における左方向)に搖動すると、可動接片23の第2荷重片235aに接触して荷重が加わる。すると、可動接片23は、第1実施形態と同様に、支点Sを移動させながら搖動する。これにより、可動接片23の接触片232は、接触端子15の接触片151から離隔するため、ロッカスイッチ2は遮断状態となる。 The button 21 has a swinging piece 213. The swinging piece 213 swings around the shaft 211 as a rotation axis in response to a pressing operation on the button 11. In the vicinity of the swinging piece 213, the second load pieces 235a and 235b of the movable contact piece 23 are arranged in contact with each other or with a slight gap therebetween. Therefore, for example, when the swinging piece 213 swings away from the contact terminal 15 (that is, leftward in the drawing), a load is applied by contacting the second load piece 235a of the movable contact piece 23. Then, the movable contact piece 23 swings while moving the fulcrum S as in the first embodiment. As a result, the contact piece 232 of the movable contact piece 23 is separated from the contact piece 151 of the contact terminal 15, so that the rocker switch 2 is turned off.
 また例えば、図示はしないが、遮断状態にあるロッカスイッチ2において、搖動片213が接触端子15に近づく方向(すなわち、図面における右方向)に搖動すると、可動接片23の第2荷重片235bに接触して荷重が加わる。すると、可動接片23は、第1実施形態と同様に、支点Sを移動させながら搖動する。これにより、可動接片23の接触片232は、接触端子15の接触片151に接触するため、ロッカスイッチ2は通電状態となる。
 このように、第2実施形態の場合、第1実施形態と異なり、ボタン11に対する押下操作を直接的に可動接片23に伝達することもできる。
Further, for example, although not shown, in the rocker switch 2 in the cut-off state, when the swinging piece 213 swings in the direction approaching the contact terminal 15 (that is, rightward in the drawing), the second load piece 235b of the movable contact piece 23 Load is applied upon contact. Then, the movable contact piece 23 swings while moving the fulcrum S as in the first embodiment. As a result, the contact piece 232 of the movable contact piece 23 comes into contact with the contact piece 151 of the contact terminal 15, so that the rocker switch 2 is turned on.
As described above, in the case of the second embodiment, unlike the first embodiment, the pressing operation on the button 11 can be directly transmitted to the movable contact piece 23.
 (可動接片)
 可動接片23は、コイルバネ12の圧縮又は開放により生じる弾性エネルギーを利用して搖動する接片であり、第1荷重片231と、接触片232と、端部233と、底部234と、第2荷重片235a及び235bと、を含むように構成されている。可動接片23は、共通端子14の上面に形成された受け部141において、支点Sの位置を移動させながら搖動する。
 第1荷重片231は、コイルバネ12に嵌合される部材であり、コイルバネ12に嵌合された第1荷重片231の端部は、可動接片23がコイルバネ12の圧縮又は開放により生じた弾性エネルギーを利用して搖動する際の荷重点LPとなる。
