At this time, the pressing portion 285 of the push button knob 280 is in contact with the upper surface of the reversing plate 23 (that is, the pressing switch 21). Thus, the assembly of the rotary switch 1 is completed. Note that the above assembling procedure is one example, and it goes without saying that the assembling may be performed using other various assembling procedures.

次に、上記回転式スイッチ１の操作方法（動作）について説明する。ここではまず、図３に示すように、トルク切替レバー２２０の各開口２２９内に第１当接部１８０−１全体が収納され、同時に、各開口部２３０内に第２当接部１８０−２全体が収納されているとする。図８はこのときの開口部２２９、開口部２３０、第１当接部１８０−１、第２当接部１８０−２、クリック係合部２５９、弾接バネ１２０、補強板９０、回転部材７０の位置関係を示す概略展開断面図である。同図に示すように、各開口部２２９，２３０内に第１，第２当接部１８０−１，１８０−２全体がそれぞれ収納されているときは、第１当接部１８０−１の弾接部１８１はトルク切替レバー２２０の本体部２２１の上面から上方向に向かって突出している。従って、弾発部材１６０によって押し上げられている第１当接部１８０−１の弾接部１８１は、軸付き回転体２５０の下面に形成されたクリック係合部２５９に接触して係合する位置にある。一方このとき、作動部材１７０の弾接体取付部１７５の下端に取り付けた弾接バネ１２０の弾接部１２７は、補強板９０の弾接面９５から所定寸法だけ離れている。 Next, an operation method (operation) of the rotary switch 1 will be described. Here, first, as shown in FIG. 3, the entire first contact portion 180-1 is housed in each opening 229 of the torque switching lever 220, and at the same time, the second contact portion 180-2 is accommodated in each opening 230. It is assumed that the whole is stored. FIG. 8 shows the opening 229, the opening 230, the first contact portion 180-1, the second contact portion 180-2, the click engaging portion 259, the elastic contact spring 120, the reinforcing plate 90, and the rotating member 70 at this time. It is a schematic expanded sectional view which shows the positional relationship of. As shown in the drawing, when the entire first and second contact portions 180-1 and 180-2 are stored in the openings 229 and 230, respectively, the elasticity of the first contact portion 180-1 is used. The contact portion 181 protrudes upward from the upper surface of the main body 221 of the torque switching lever 220. Therefore, the elastic contact portion 181 of the first contact portion 180-1 pushed up by the elastic member 160 is brought into contact with and engages with the click engaging portion 259 formed on the lower surface of the rotating body 250 with the shaft. It is in. On the other hand, at this time, the elastic contact portion 127 of the elastic contact spring 120 attached to the lower end of the elastic contact member attachment portion 175 of the operation member 170 is separated from the elastic contact surface 95 of the reinforcing plate 90 by a predetermined dimension.

そしてこの状態で、回転つまみ３００を回転すると、図２に示すように、回転つまみ３００と一体に押釦つまみ２８０と軸付き回転体２５０と補強板９０と回転部材７０と摺動子６０が、回転軸Ｌ１を中心として回転し、摺動子６０の弾接部６７が第２フレキシブル回路基板５０の摺接パターン５３上を摺動し、その出力信号が変化する。回転つまみ３００を回転すると、これと一体に軸付き回転体２５０の下面に形成したクリック係合部２５９も回転するので、図８に示すように、これに弾接している第１当接部１８０−１の弾接部１８１は、クリック係合部２５９の凹凸上を上下動しながら弾接し、これによって回転つまみ３００の回転にクリック感触を与える。回転つまみ３００を回転した際、弾接バネ１２０の各弾接部１２７は補強板９０の弾接面９５には当接しない。つまり、弾接部１２７と弾接面９５の離間距離は、弾接部１８１がクリック係合部２５９の凸の部分を乗り越える際も接触しない離間寸法に形成されている。 When the rotary knob 300 is rotated in this state, as shown in FIG. 2, the push button knob 280, the rotating body 250 with the shaft, the reinforcing plate 90, the rotating member 70, and the slider 60 are integrally rotated with the rotating knob 300. Rotating around the axis L1, the elastic contact portion 67 of the slider 60 slides on the sliding contact pattern 53 of the second flexible circuit board 50, and the output signal changes. When the rotary knob 300 is rotated, the click engaging portion 259 formed on the lower surface of the rotating body 250 with the shaft is also rotated integrally therewith, so that the first contact portion 180 elastically contacting the rotary knob 300 as shown in FIG. The -1 elastic contact portion 181 elastically contacts the click engagement portion 259 while moving up and down on the unevenness, thereby giving a click feeling to the rotation of the rotary knob 300. When the rotary knob 300 is rotated, each elastic contact portion 127 of the elastic contact spring 120 does not contact the elastic contact surface 95 of the reinforcing plate 90. In other words, the separation distance between the elastic contact portion 127 and the elastic contact surface 95 is set to a distance such that the elastic contact portion 181 does not come into contact with the click engaging portion 259 even when it climbs over the convex portion.

次に、トルク切替レバー２２０のレバー２３１を、真上から見て左方向に所定角度回動すると、トルク切替レバー２２０のクリック当接部２３３の一方の凹部に弾接していたクリック用ボール２００が、もう一方の凹部に凸部を乗り越えて係合する際に、クリック感触を生じる。なおトルク切替レバー２２０の回動範囲は、トルク切替レバー２２０の一対の被当接面２３９に、ケース１３０の一対の当接面１４２が当接する範囲であり、言い換えれば、クリック用ボール２００がクリック当接部２３３の一方の凹部からもう一方の凹部に移動する範囲である。 Next, when the lever 231 of the torque switching lever 220 is rotated by a predetermined angle to the left as viewed from directly above, the click ball 200 that has elastically contacted one of the recesses of the click contact portion 233 of the torque switching lever 220 is moved. In addition, a click feel is generated when engaging with the other concave portion over the convex portion. The rotation range of the torque switching lever 220 is a range in which the pair of contact surfaces 142 of the case 130 abut on the pair of contact surfaces 239 of the torque switching lever 220. In other words, the click ball 200 clicks. This is a range in which the contact portion 233 moves from one concave portion to the other concave portion.

図７はトルク切替レバー２２０を上記のように回動したときの概略断面図（図２と同一部分の断面図）である。また図９はこのときの開口部２２９、開口部２３０、第１当接部１８０−１、第２当接部１８０−２、クリック係合部２５９、弾接バネ１２０、補強板９０、回転部材７０の位置関係を示す概略展開断面図である。トルク切替レバー２２０を回動したとき、作動部材１７０に対してトルク切替レバー２２０が、図８の矢印Ｃで示す方向に相対的に移動する。これによって、トルク切替レバー２２０に設けた開口部２２９の外周辺２２９ａ部分が第１当接部１８０−１の傾斜部１８５に接触し、同時にトルク切替レバー２２０に設けた開口部２３０の外周辺２３０ａ部分が第２当接部１８０−２の傾斜部１９３に接触し、第１，第２当接部１８０−１，１８０−２（即ち作動部材１７０全体）が真下方向に移動する。これによって、図９に示すように、第１当接部１８０−１の弾接部１８１が下降してトルク切替レバー２２０の開口部２２９内に入り込む。このときトルク切替レバー２２０の下面には、第１当接部１８０−１の支持部１８３と、第２当接部１８０−２の支持部１９１が弾接する。従って、この状態のときは、第１当接部１８０−１の弾接部１８１は、軸付き回転体２５０の本体部２５１下面に形成されたクリック係合部２５９から乖離し、接触（弾接）しない。一方このとき、作動部材１７０の弾接体取付部１７５の下端に取り付けた弾接バネ１２０の弾接部１２７は、下降することで、補強板９０の弾接面９５に弾接する。 FIG. 7 is a schematic cross-sectional view (cross-sectional view of the same portion as FIG. 2) when the torque switching lever 220 is rotated as described above. FIG. 9 shows the opening 229, the opening 230, the first contact portion 180-1, the second contact portion 180-2, the click engaging portion 259, the elastic contact spring 120, the reinforcing plate 90, and the rotating member at this time. It is a schematic expanded sectional view which shows the positional relationship of 70. When the torque switching lever 220 is rotated, the torque switching lever 220 moves relative to the operating member 170 in the direction indicated by the arrow C in FIG. As a result, the outer periphery 229a of the opening 229 provided in the torque switching lever 220 comes into contact with the inclined portion 185 of the first contact portion 180-1, and at the same time, the outer periphery 230a of the opening 230 provided in the torque switching lever 220. The portion contacts the inclined portion 193 of the second contact portion 180-2, and the first and second contact portions 180-1 and 180-2 (that is, the entire operation member 170) move right below. Thereby, as shown in FIG. 9, the elastic contact portion 181 of the first contact portion 180-1 descends and enters the opening 229 of the torque switching lever 220. At this time, the support portion 183 of the first contact portion 180-1 and the support portion 191 of the second contact portion 180-2 elastically contact the lower surface of the torque switching lever 220. Therefore, in this state, the elastic contact portion 181 of the first contact portion 180-1 separates from the click engaging portion 259 formed on the lower surface of the main body 251 of the rotating body 250 with the shaft, and contacts (elastic contact). )do not do. On the other hand, at this time, the elastic contact portion 127 of the elastic contact spring 120 attached to the lower end of the elastic contact member attachment portion 175 of the operating member 170 comes down and makes elastic contact with the elastic contact surface 95 of the reinforcing plate 90.

そしてこの状態で、回転つまみ３００を回転すると、前述のように、摺動子６０の弾接部６７が第２フレキシブル回路基板５０の摺接パターン５３上を摺動し、その出力信号が変化する。回転つまみ３００を回転する際、これと一体に軸付き回転体２５０の下面に形成したクリック係合部２５９も回転するが、図９に示すように、このクリック係合部２５９に第１当接部１８０−１の弾接部１８１は弾接しないので、回転つまみ３００の回転にクリック感触は生じない。一方、この状態のときは、弾接バネ１２０の弾接部１２７が補強板９０の弾接面９５に弾接しているので、回転つまみ３００の回転の際、前記弾接によって、その回転に所手の回転トルクを生じる。 When the rotary knob 300 is rotated in this state, the elastic contact portion 67 of the slider 60 slides on the sliding contact pattern 53 of the second flexible circuit board 50 as described above, and the output signal changes. . When the rotary knob 300 is rotated, the click engaging portion 259 formed on the lower surface of the rotating body 250 with the shaft also rotates together therewith, but as shown in FIG. Since the elastic contact portion 181 of the portion 180-1 does not elastically contact, the click of the rotation knob 300 does not occur. On the other hand, in this state, the elastic contact portion 127 of the elastic contact spring 120 is in elastic contact with the elastic contact surface 95 of the reinforcing plate 90. Therefore, when the rotary knob 300 rotates, the elastic contact causes the elastic contact. Generates hand torque.

前記トルク切替レバー２２０を元の位置に回動して戻せば（図９に示す矢印Ｄ方向に移動）、開口部２２９の外周辺２２９ａ部分が再び第１当接部１８０−１の傾斜部１８５に接触しながらその上を摺動し、同時に開口部２３０の外周辺２３０ａ部分が再び第２当接部１８０−２の傾斜部１９３に接触しながらその上を摺動し、第１，第２当接部１８０−１，１８０−２（即ち作動部材１７０全体）が真上方向に移動し、これによって、第１当接部１８０−１の弾接部１８１が上昇してトルク切替レバー２２０の開口部２２９から上方に突出してゆき、図８に示す状態に戻る。これによって、第１当接部１８０−１の弾接部１８１は、軸付き回転体２５０のクリック係合部２５９に弾接し、再びクリック感触を生じる状態になり、同時に、弾接バネ１２０の各弾接部１２７は補強板９０の弾接面９５から所定距離離間し、再び回転つまみ３００の回転トルクが小さくなる状態になる。 When the torque switching lever 220 is turned back to the original position (moved in the direction of arrow D shown in FIG. 9), the outer peripheral portion 229a of the opening 229 is again inclined 185 of the first contact portion 180-1. And at the same time, the outer peripheral portion 230a of the opening 230 slides on the inclined portion 193 of the second contact portion 180-2 again while contacting with the first and second portions. The contact portions 180-1 and 180-2 (that is, the entire operation member 170) move right above, whereby the elastic contact portion 181 of the first contact portion 180-1 rises and the torque switching lever 220 It protrudes upward from the opening 229 and returns to the state shown in FIG. As a result, the elastic contact portion 181 of the first contact portion 180-1 elastically contacts the click engaging portion 259 of the rotating body 250 with the shaft, so that a click feeling is again generated. The elastic contact portion 127 is separated from the elastic contact surface 95 of the reinforcing plate 90 by a predetermined distance, and the rotational knob 300 is again in a state where the rotational torque is reduced.

つまり上記回転式スイッチ１によれば、トルク切替レバー２２０の回動位置に応じて、回転つまみ３００を回転した際にクリック感触が生じると同時にその回転トルクを小さくする状態と、回転つまみ３００を回転した際にクリック感触が生じないと同時にその回転トルクを大きくする状態とを、切り替えることができる。さらにいえば、クリック感触が生じるときは、そのことによって回転つまみ３００の回転トルクが大きくなるので、その分、弾接バネ１２０による回転トルクを小さくして過度に回転トルクが大きくならないようにし、クリック感触が生じないときは、そのことによって回転つまみ３００の回転トルクが小さくなるので、その分、弾接バネ１２０による回転トルクを大きくして回転トルクが適度に大きくなるようにしている。これによって、クリック感触が生じる時も生じない時も、適度な回転トルクが得られるようになる。 In other words, according to the rotary switch 1, according to the rotational position of the torque switching lever 220, a click feel is generated when the rotary knob 300 is rotated, and the rotation torque is reduced at the same time. In this case, it is possible to switch between a state in which a click feeling does not occur and a state in which the rotational torque is increased. Furthermore, when a click feeling is generated, the rotation torque of the rotary knob 300 is increased by that. Therefore, the rotation torque by the elastic contact spring 120 is reduced by that amount so that the rotation torque is not excessively increased. When the touch does not occur, the rotation torque of the rotary knob 300 is reduced by that. Therefore, the rotation torque by the elastic contact spring 120 is increased accordingly, so that the rotation torque is appropriately increased. As a result, an appropriate rotation torque can be obtained regardless of whether or not the click feeling occurs.

一方、押釦つまみ２８０のつまみ部２８１の上面を下方向に向けて押圧してこれを下降すれば、その押圧部２８５が反転板２３を押圧してこれを反転し、押圧スイッチ２１がオンする。前記押圧を解除すれば、反転板２３の弾性復帰力によって押釦つまみ２８０は元の位置に押し上げられ、押圧スイッチ２１はオフする。 On the other hand, when the upper surface of the knob portion 281 of the push button knob 280 is pressed downward and lowered, the pressing portion 285 presses the reversing plate 23 to reverse it, and the pressing switch 21 is turned on. When the pressing is released, the push button knob 280 is pushed up to the original position by the elastic return force of the reversing plate 23, and the pressing switch 21 is turned off.

なお、上記回転式スイッチ１において、さらに、切替体取付部材１００（例えば第２フレキシブル回路基板５０に対向する側の面）に別途摺動子を取り付けると共に、第２フレキシブル回路基板５０の上面に前記摺動子が摺接する摺接パターン（例えば位置検出用パターン）を設け、これによって切替体取付部材１００と一体に回転するトルク切替レバー２２０の位置（回動位置）を検出等できるように構成しても良い。 In the rotary switch 1, a slider is separately attached to the switching body attaching member 100 (for example, the surface facing the second flexible circuit board 50), and the switching member is attached to the upper surface of the second flexible circuit board 50. A sliding contact pattern (for example, a pattern for position detection) with which the slider slides is provided so that the position (rotational position) of the torque switching lever 220 that rotates integrally with the switching body mounting member 100 can be detected. May be.

また上記回転式スイッチ１においては、回転つまみ３００を回転した際の、クリック感触の有無と回転トルクの増減とを連動させる構成としたが、クリック感触の有無は必須ではなく、クリック感触の有無にかかわらず、単に回転トルクの大きさを変更するように構成しても良い。この場合、例えば上記例では、第１，第２当接部１８０−１，１８０−２と開口部２２９，２３０の形状を全て、第２当接部１８０−２と開口部２３０の形状にし、またクリック係合部２５９を省略する等すれば良い。 Further, in the rotary switch 1, the presence / absence of the click feeling and the increase / decrease of the rotation torque when the rotary knob 300 is rotated are linked, but the presence / absence of the click feeling is not essential. Regardless, the configuration may be such that the magnitude of the rotational torque is simply changed. In this case, for example, in the above example, the shapes of the first and second contact portions 180-1 and 180-2 and the openings 229 and 230 are all changed to the shape of the second contact portion 180-2 and the opening 230. Further, the click engagement portion 259 may be omitted.

また上記回転式スイッチ１においては、トルク切替レバー２２０を回動することで、弾接バネ１２０の弾接部１２７を弾接面９５に弾接する位置と乖離する位置とに変更するように構成したが（つまり、弾接バネ１２０によって回転トルクが生じる場合と生じない場合に変更するように構成したが）、トルク切替レバー２２０を回動することで、弾接バネ１２０の弾接部１２７を弾接面９５に強く弾接する位置と弱く弾接する位置とに変更するように構成してもよい（つまり、弾接バネ１２０による回転トルクが大きい場合と小さい場合に変更するように構成してもよい）。 Further, in the rotary switch 1, by rotating the torque switching lever 220, the elastic contact portion 127 of the elastic contact spring 120 is changed to a position at which the elastic contact portion 127 elastically contacts the elastic contact surface 95 and a position separated therefrom. However, the torque switching lever 220 is rotated to cause the elastic contact portion 127 of the elastic contact spring 120 to be elasticated. The position may be changed between a position where the elastic contact with the contact surface 95 is strong and a position where the elastic contact with the contact surface 95 is weak (that is, the position may be changed when the rotational torque by the elastic spring 120 is large or small). ).

また上記第１当接部１８０−１は、弾接部１８１と傾斜部１８５の間に支持部１８３を設けたが、支持部１８３を省略して、弾接部１８１と傾斜部１８５を直接接続しても良い。このとき傾斜部１８５の傾斜角度と、これに接続する弾接部１８１の傾斜面の傾斜角度を同一にしても良い。またこのとき、弾接部１８１の頂点部分を、支持部１８３の代りに用い、トルク切替レバー２２０を図９に示すように回動したときに、弾接部１８１の頂点部分がトルク切替レバー２２０の下面に弾接するように構成しても良い。また第２当接部１８０−２の支持部１９１を省略しても良い。 In the first contact portion 180-1, the support portion 183 is provided between the elastic contact portion 181 and the inclined portion 185, but the support portion 183 is omitted and the elastic contact portion 181 and the inclined portion 185 are directly connected. You may. At this time, the inclination angle of the inclined portion 185 and the inclination angle of the inclined surface of the elastic contact portion 181 connected thereto may be the same. Also, at this time, when the torque switching lever 220 is rotated as shown in FIG. 9, the top of the elastic contact portion 181 is used instead of the support portion 183, and the top of the elastic contact portion 181 is moved to the torque switching lever 220. May be configured to be in elastic contact with the lower surface of the. Further, the support portion 191 of the second contact portion 180-2 may be omitted.

以上説明したように、回転式スイッチ１は、弾接部１２７を形成した弾接バネ１２０と、回転軸Ｌ１を中心に回転すると共に前記弾接バネ１２０の弾接部１２７に弾接することで回転トルクを付与する弾接面９５を設けた回転体（回転つまみ３００と軸付き回転体２５０と補強板９０と回転部材７０）と、前記回転体と一体に回転することで出力信号を変化させる検出手段（摺動子６０及び摺接パターン５３）と、前記回転軸Ｌ１を中心に回動可能であって回動位置に応じて前記弾接部１２７の位置を変更させるトルク切替レバー２２０とを具備し、前記トルク切替レバー２２０を回動することで、前記弾接部１２７が移動し、前記弾接面９５と前記弾接部１２７間の弾接状態を変更するように構成している。これによって、トルク切替レバー２２０を回動するだけで、回転体を回転する際の回転トルクの強弱を容易に変更することができる。 As described above, the rotary switch 1 rotates around the rotation axis L1 and the elastic contact spring 127 formed with the elastic contact portion 127, and rotates by elastically contacting the elastic contact portion 127 of the elastic contact spring 120. A rotating body (rotary knob 300, rotating body 250 with shaft, reinforcing plate 90, and rotating member 70) provided with an elastic contact surface 95 for applying a torque, and detection of changing an output signal by rotating integrally with the rotating body Means (slider 60 and sliding contact pattern 53), and a torque switching lever 220 rotatable about the rotation axis L1 and changing the position of the elastic contact portion 127 according to the rotating position. By rotating the torque switching lever 220, the elastic contact portion 127 is moved, and the elastic contact state between the elastic contact surface 95 and the elastic contact portion 127 is changed. Thus, the strength of the rotation torque when rotating the rotating body can be easily changed only by rotating the torque switching lever 220.

また上記回転式スイッチ１は、前記弾接バネ１２０と一体に上下動する作動部材１７０を有し、前記トルク切替レバー２２０には、このトルク切替レバー２２０を回転した際に、前記作動部材１７０に設けた当接部１８０（１８０−１，１８０−２）に干渉してこの作動部材１７０及び前記弾接バネ１２０を上下動させて、前記弾接面９５と前記弾接部１２７間の弾接状態を変更させる開口部２２９，２３０を設けている。作動部材１７０に設けた当接部１８０（１８０−１，１８０−２）と、トルク切替レバー２２０に設けた開口部２２９，２３０とを用いることで、トルク切替レバー２２０による弾接バネ１２０の上下動をスムーズに行わせることが可能になる。 In addition, the rotary switch 1 has an operating member 170 that moves up and down integrally with the elastic contact spring 120, and the torque switching lever 220 is provided with the operating member 170 when the torque switching lever 220 is rotated. The operating member 170 and the elastic contact spring 120 are moved up and down by interfering with the provided contact portions 180 (180-1 and 180-2), so that the elastic contact between the elastic contact surface 95 and the elastic contact portion 127 is performed. Openings 229 and 230 for changing the state are provided. By using the contact portions 180 (180-1, 180-2) provided on the operation member 170 and the openings 229, 230 provided on the torque switching lever 220, the elastic contact spring 120 can be moved up and down by the torque switching lever 220. The movement can be performed smoothly.

また上記回転スイッチ１の回転体は、回転つまみ３００と、前記検出手段（摺動子６０）を取り付ける回転部材７０と、前記回転つまみ３００と回転部材７０間を接続する軸２５３とを有し、前記回転つまみ３００と回転部材７０間に、前記トルク切替レバー２２０と前記作動部材１７０とを設置し、前記トルク切替レバー２２０の開口部２２９，２３０に前記作動部材１７０の突起状の当接部１８０を挿入し、前記トルク切替レバー２２０を回動することで、このトルク切替レバー２２０の開口部２２９，２３０の外周辺２２９ａ，２３０ａ部分が前記作動部材１７０の当接部１８０に干渉して作動部材１７０を上下動させる構成となっている。これによって、トルク切替レバー２２０の回動動作を作動部材１７０の上下の動作にスムーズに変換することができる。 The rotating body of the rotary switch 1 has a rotating knob 300, a rotating member 70 to which the detecting means (slider 60) is attached, and a shaft 253 connecting the rotating knob 300 and the rotating member 70, The torque switching lever 220 and the operating member 170 are installed between the rotary knob 300 and the rotating member 70, and the projecting abutting portions 180 of the operating member 170 fit into the openings 229 and 230 of the torque switching lever 220. Is inserted, and the torque switching lever 220 is rotated, so that the outer peripheral portions 229a and 230a of the openings 229 and 230 of the torque switching lever 220 interfere with the contact portion 180 of the operating member 170 and actuate the operating member. 170 is moved up and down. Thus, the turning operation of the torque switching lever 220 can be smoothly converted into the up and down operation of the operating member 170.
