FIG. 2 illustrates the micro switch 2 of the first embodiment. In addition, in the specification of this application, the direction of the microswitch 2 is expressed in FIG. 2 with the front left as the front, the deep right side as the rear, the upper as the upper, and the lower as the lower, but this is for The directions for ease of explanation are not a limitation on the assembly direction of the micro switch 2. As described above, the micro switch 2 is housed in an electronic device such as the operating device 1, and accepts the pressing operation received by the pressing operation portion 10 of the operating device 1 as an external pressing.

微開關2包括呈大致長方體狀的框體20。框體20藉由下部的基座（base）及上部的蓋體（cover）而形成。正面視時，自框體20的中心起至向左側橫向1/4左右的長度的位置，以朝上方的方式開設有開放框體20的上表面而成的插嵌口200。並且，在框體20的上表面的插嵌口200插嵌有承接來自框體20的外部的按壓而上下移動的按下構件21。另外，在本申請案中，框體20的插嵌口200是指嵌入按下構件21的入口部分，在圖2所示的示例中，是嵌入按下構件21的部位的周圍的邊緣的部分。而且，自框體20的下表面起，突出有作為能夠連接其他電氣構件的金屬片的三根連接端子部22。The micro switch 2 includes a frame 20 having a substantially rectangular parallelepiped shape. The frame body 20 is formed by a lower base and an upper cover. When viewed from the front, from the center of the frame 20 to a position of about 1/4 of the length to the left side, an insertion slot 200 that opens the upper surface of the frame 20 is opened upward. In addition, a pressing member 21 that receives pressing from the outside of the frame 20 and moves up and down is inserted into the insertion slot 200 on the upper surface of the frame 20. In addition, in the present application, the insertion slot 200 of the frame body 20 refers to the entrance portion where the pressing member 21 is inserted. In the example shown in FIG. 2, it is the part of the periphery of the portion where the pressing member 21 is inserted. . In addition, from the lower surface of the frame body 20, three connection terminal portions 22 that are metal pieces that can be connected to other electrical components protrude.

在框體20中，自開設插嵌口200的上表面的部位起至連續的前後的面，刻製有對按下構件21的上下的移動進行引導的引導槽201。按下構件21的上表面以空開若干間隙的方式插嵌於插嵌口200，成為對框體20內進行遮蔽以免異物進入的板狀的遮蔽部210。而且，按下構件21的前表面及後表面以空開若干間隙的方式嵌合於框體20的引導槽201，成為被引導槽201引導的嵌合板211。In the frame body 20, a guide groove 201 that guides the vertical movement of the pressing member 21 is engraved from the position where the upper surface of the insertion slot 200 is opened to the continuous front and rear surfaces. The upper surface of the pressing member 21 is inserted into the insertion slot 200 with a few gaps open, and becomes a plate-shaped shielding portion 210 that shields the inside of the frame 20 to prevent foreign matter from entering. Furthermore, the front surface and the rear surface of the pressing member 21 are fitted into the guide groove 201 of the frame body 20 with a slight gap, and become a fitting plate 211 guided by the guide groove 201.

在按下構件21的嵌合板211的下端突出設置有向左右突出的限制突起212。而且，框體20的引導槽201的下端成為左右方向的寬度寬的限制槽202。限制槽202的左右方向的長度比包括限制突起212的按下構件21的下端的左右方向的長度長若干，而且，限制槽202的上下方向的高度為限制突起212的上下方向的高度的2倍左右的高度。因此，藉由將按下構件21的限制突起212卡合於框體20的限制槽202，則按下構件21的上下方向的移動受到限制。The lower end of the fitting plate 211 of the pressing member 21 is provided with a restricting protrusion 212 protruding left and right. Furthermore, the lower end of the guide groove 201 of the frame body 20 becomes a restriction groove 202 with a wide width in the left-right direction. The length of the restriction groove 202 in the left-right direction is slightly longer than the length of the lower end of the pressing member 21 including the restriction protrusion 212 in the left-right direction, and the height of the restriction groove 202 in the vertical direction is twice the height of the restriction protrusion 212 in the vertical direction Height from left to right. Therefore, by engaging the restriction protrusion 212 of the pressing member 21 with the restriction groove 202 of the frame body 20, the vertical movement of the pressing member 21 is restricted.

進而，在按下構件21的遮蔽部210的上表面突出設置有在前後方向上***的一條被按壓突起210a，被按壓突起210a承接來自外部的按壓。Furthermore, on the upper surface of the shielding portion 210 of the pressing member 21, a pressed protrusion 210a protruding in the front-rear direction is protrudingly provided, and the pressing protrusion 210a receives pressing from the outside.

在如此形成的微開關2中，操作裝置1所承接到的來自外部的按下操作被作為來自框體20的外部的按壓而經由被按壓突起210a傳遞至按下構件21。按下構件21接受來自外部的按壓而向作為框體20的內側的下側移動，當來自外部的按壓釋放時，向作為框體20的外側的上側移動。即，按下構件21根據來自外部的按壓狀況而在上側（框體20的外側）的第一位置與下側（框體20的內側）的第二位置之間，以按下構件21的嵌合板211藉由框體20的引導槽201引導的方式進行移動。作為上限的第一位置及作為下限的第二位置是藉由由框體20的限制槽202與按下構件21的限制突起212的卡合構成的限制來決定。In the micro switch 2 formed in this way, the pressing operation from the outside received by the operating device 1 is transmitted to the pressing member 21 via the pressed protrusion 210 a as a pressing from the outside of the housing 20. The pressing member 21 receives pressure from the outside and moves to the lower side as the inner side of the housing 20, and when the pressure from the outside is released, moves to the upper side as the outer side of the housing 20. That is, the pressing member 21 is located between the first position on the upper side (outside the frame 20) and the second position on the lower side (inside the frame 20) according to the pressing condition from the outside, so that the pressing member 21 is embedded The hinge 211 is moved by being guided by the guide groove 201 of the frame 20. The first position as the upper limit and the second position as the lower limit are determined by the restriction formed by the engagement of the restriction groove 202 of the frame body 20 and the restriction protrusion 212 of the pressing member 21.

其次，對微開關2的內部結構進行說明。圖3是表示本申請案所記載的微開關2的剖面及外觀的一例的概略立體剖面圖。圖4是表示本申請案所記載的微開關2的剖面的一例的概略剖面圖。圖3及圖4對第1實施方式的微開關2進行例示，並將包括圖2所示的A-B線段的垂直面所切斷的剖面以朝向箭頭方向的方式表示。另外，圖3以來自與圖2相同的方向的視點來進行展示，圖4是以來自正面的視點來進行表示。Next, the internal structure of the micro switch 2 will be described. 3 is a schematic perspective cross-sectional view showing an example of the cross section and appearance of the micro switch 2 described in the present application. FIG. 4 is a schematic cross-sectional view showing an example of the cross section of the micro switch 2 described in the present application. 3 and 4 illustrate the microswitch 2 of the first embodiment, and show the cross section cut by the vertical plane including the line segment A-B shown in FIG. 2 facing the arrow direction. In addition, FIG. 3 is shown with a viewpoint from the same direction as FIG. 2, and FIG. 4 is shown with a viewpoint from the front.

在微開關2的框體20內，確保有作為接點室24的區域，所述接點室24收容作為開關而對電氣電路進行開閉的接點機構23。在接點室24的上方確保有用以供按下構件21上下移動的區域作為按下室25。而且，在按下室25的底面開設有供按下構件21插通的插通孔250，按下室25的底面與接點室24的上表面藉由插通孔250而貫通。In the housing 20 of the micro switch 2, an area is secured as a contact chamber 24, and the contact chamber 24 houses a contact mechanism 23 that opens and closes an electric circuit as a switch. A region for the pressing member 21 to move up and down is secured above the contact chamber 24 as the pressing chamber 25. Furthermore, an insertion hole 250 through which the pressing member 21 is inserted is opened in the bottom surface of the pressing chamber 25, and the bottom surface of the pressing chamber 25 and the upper surface of the contact chamber 24 are penetrated by the insertion hole 250.

在按下室25內，在底面所開設的插通孔250的周圍，形成有朝上側（框體20的外側）突出的內壁部251，藉由內壁部251圍繞著插通孔250的周圍。內壁部251的高度即內壁部251的插通方向的長度形成為比插嵌口200與遮蔽部210的緣部的間隙長。In the press chamber 25, an inner wall portion 251 protruding upward (outside the frame 20) is formed around the insertion hole 250 opened on the bottom surface. The inner wall portion 251 surrounds the insertion hole 250 around. The height of the inner wall portion 251, that is, the length of the insertion direction of the inner wall portion 251 is formed to be longer than the gap between the insertion slot 200 and the edge of the shielding portion 210.

在按下室25內上下移動的按下構件21的下部形成為插通於插通孔250的插通部213，插通部213的下端（朝向框體20內的內端）插通插通孔250而到達接點室24內。插通部213以空開若干間隙的方式插嵌於插通孔250，因此，按下構件21能夠一面維持著將插通部213插通於插通孔250的狀態一面上下移動。按下構件21的插通部213將按下構件21的上下移動傳遞給接點室24內，作用於接點室24內的接點機構23。The lower part of the pressing member 21 that moves up and down in the pressing chamber 25 is formed as an insertion portion 213 inserted into the insertion hole 250, and the lower end of the insertion portion 213 (toward the inner end in the housing 20) is inserted through The hole 250 reaches the contact chamber 24. The insertion portion 213 is inserted into the insertion hole 250 with a few gaps open. Therefore, the pressing member 21 can move up and down while maintaining the insertion portion 213 inserted into the insertion hole 250. The insertion portion 213 of the pressing member 21 transmits the vertical movement of the pressing member 21 to the contact chamber 24 and acts on the contact mechanism 23 in the contact chamber 24.

如前所述，在按下構件21的上部形成有以空開若干間隙的方式插嵌於插嵌口200的板狀的遮蔽部210。而且，在按下構件21中，在與插嵌口200接近的遮蔽部210的緣部形成有朝下側（框體20的內側）突出的外壁部210b。As described above, the upper portion of the pressing member 21 is formed with a plate-shaped shielding portion 210 that is inserted into the insertion slot 200 with a certain gap. In addition, in the pressing member 21, an outer wall portion 210 b protruding downward (inside the frame body 20) is formed on the edge of the shielding portion 210 close to the insertion fitting opening 200.

如此形成的按下構件21的剖面形狀，藉由在上部於水平方向上長的遮蔽部210及向下方延伸的插通部213而形成為大致T字狀。而且，按下構件21在相對於插通孔250而成為與接點室24相反的一側的上部，具有對插通孔250進行遮蔽的遮蔽部210。遮蔽部210中，自上方的視點，即自插通部213的插通方向觀察的形狀以藉由比插通孔250大的面積覆蓋插通孔250的方式形成。因此，在以來自上方的視點對微開關2進行目視確認的情況下，插通孔250不會露出而藉由遮蔽部210遮蔽。在框體20內，在按下室25內的底面，開設有插通孔250，按下室25的上方為經開放的插嵌口200。因對插嵌口200插嵌按下構件21，所以開設有插通孔250的按下室25藉由遮蔽部210以空開若干間隙的方式關閉。插通孔250開設在按下室25的底面的大致中央，因此遮蔽部210覆蓋插通孔250。The cross-sectional shape of the pressing member 21 formed in this way is formed into a substantially T-shape by the shielding portion 210 that is elongated in the horizontal direction at the upper portion and the insertion portion 213 that extends downward. In addition, the pressing member 21 has a shielding portion 210 that shields the insertion hole 250 at an upper portion on the side opposite to the contact chamber 24 with respect to the insertion hole 250. In the shielding portion 210, a shape viewed from an upper viewpoint, that is, from the insertion direction of the insertion portion 213, is formed so as to cover the insertion hole 250 with a larger area than the insertion hole 250. Therefore, when the microswitch 2 is visually confirmed from a viewpoint from above, the insertion hole 250 is not exposed but is shielded by the shielding portion 210. In the frame body 20, an insertion hole 250 is opened on the bottom surface of the pressing chamber 25, and an insertion slot 200 is opened above the pressing chamber 25. Since the pressing member 21 is inserted into the insertion insertion hole 200, the pressing chamber 25 with the insertion hole 250 is closed by the shielding portion 210 with a certain gap. The insertion hole 250 is opened in the approximate center of the bottom surface of the pressing chamber 25, so the shielding portion 210 covers the insertion hole 250.

對收容於接點室24內的接點機構23進行說明。在接點室24內，作為接點機構23而配設有共通接點端子230、第一接點端子231、第二接點端子232、可動接觸片233等構件。共通接點端子230配設於接點室24內的左側，與左側的連接端子部22電性連接。第一接點端子231配設於接點室24內的右上側，與右側的連接端子部22電性連接。第二接點端子232配設於接點室24內的右下側，與中央的連接端子部22電性連接。The contact mechanism 23 housed in the contact chamber 24 will be described. In the contact chamber 24, as the contact mechanism 23, members such as a common contact terminal 230, a first contact terminal 231, a second contact terminal 232, and a movable contact piece 233 are arranged. The common contact terminal 230 is arranged on the left side of the contact chamber 24 and is electrically connected to the connection terminal portion 22 on the left side. The first contact terminal 231 is arranged on the upper right side of the contact chamber 24 and is electrically connected to the connection terminal portion 22 on the right side. The second contact terminal 232 is arranged on the lower right side in the contact chamber 24 and is electrically connected to the central connection terminal 22.

可動接觸片233是在接點室24內在左右方向上延伸的板狀的導電性金屬構件。可動接點的左端成為卡止於共通接點端子230的固定端。可動接點的右端成為在第一接點端子231與第二接點端子232之間進行移動的自由端。另外，可動接觸片233形成為中央附近被衝壓並被折彎成圓弧狀的復位彈簧，復位彈簧被固定於接點室24內。The movable contact piece 233 is a plate-shaped conductive metal member extending in the left-right direction in the contact chamber 24. The left end of the movable contact becomes a fixed end that is locked to the common contact terminal 230. The right end of the movable contact becomes a free end for movement between the first contact terminal 231 and the second contact terminal 232. In addition, the movable contact piece 233 is formed as a return spring punched near the center and bent into an arc shape, and the return spring is fixed in the contact chamber 24.

如此構成的接點機構23中，藉由按下構件21受到按壓，插通部213向下方移動，將可動接觸片233按下。藉由可動接觸片233被按下，可動接觸片233的自由端即右端側下降，與第二接點端子232接觸。藉此，與共通接點端子230連接的左側的連接端子部22跟與第二接點端子232連接的中央的連接端子部22成為導通狀態。In the contact mechanism 23 thus configured, when the pressing member 21 is pressed, the insertion portion 213 moves downward, and the movable contact piece 233 is pressed down. When the movable contact piece 233 is pressed down, the free end of the movable contact piece 233, that is, the right end side, descends and comes into contact with the second contact terminal 232. Thereby, the connection terminal portion 22 on the left side connected to the common contact terminal 230 and the connection terminal portion 22 in the center connected to the second contact terminal 232 become conductive.

當解除按下構件21的按壓時，可動接觸片233被復位彈簧向上側施力。藉由可動接觸片233被向上側施力，插通部213（按下構件21）向上方移動。而且，藉由可動接觸片233被復位彈簧向上側施力，可動接觸片233的自由端即右端側上升，與第一接點端子231接觸。藉此，與共通接點端子230連接的左側的連接端子部22跟與第一接點端子231連接的右側的連接端子部22成為導通狀態。When the pressing of the pressing member 21 is released, the movable contact piece 233 is urged upward by the return spring. When the movable contact piece 233 is urged upward, the insertion portion 213 (the pressing member 21) moves upward. Then, as the movable contact piece 233 is urged upward by the return spring, the free end of the movable contact piece 233, that is, the right end side, rises to contact the first contact terminal 231. Thereby, the connection terminal portion 22 on the left side connected to the common contact terminal 230 and the connection terminal portion 22 on the right side connected to the first contact terminal 231 become conductive.

另外，在圖式中，圖示了按下構件21未受到按壓的狀態，但為了使各構件易於識別，將第一接點端子231與可動接觸片233離開若干來進行了記載。但是，原本，在按下構件21未受到按壓的狀態下，第一接點端子231與可動接觸片233處於接觸狀態。In addition, in the drawing, a state where the pressing member 21 is not pressed is illustrated, but in order to make each member easy to recognize, the first contact terminal 231 and the movable contact piece 233 are slightly separated and described. However, originally, when the pressing member 21 is not pressed, the first contact terminal 231 and the movable contact piece 233 are in contact.

本申請案所例示的接點機構23只不過是例示了能夠展開為各種方式的本申請案所記載的微開關2的一方式。可對本申請案的微開關2應用電路藉由插通部213的按下而進行開閉、接觸/分離的各種接點機構23。例如，可應用本申請案申請人所揭示的日本專利特開2017-16807號公報所記載的機構等各種技術。The contact mechanism 23 exemplified in the present application is only an example of one mode of the micro switch 2 described in the present application that can be expanded into various modes. The microswitch 2 of the present application can be applied to various contact mechanisms 23 that can be opened and closed, contacted and separated by pressing the insertion portion 213. For example, various technologies such as the mechanism described in Japanese Patent Laid-Open No. 2017-16807 disclosed by the applicant of this application can be applied.

對如上所述般構成的本申請案所記載的第1實施方式的微開關2的功能進行說明。圖5A及圖5B是對本申請案所記載的微開關2的剖面的一部分的示例進行放大表示的概略放大剖面圖。圖5A及圖5B是以微開關2的按下室25為中心進行放大的剖面，以容易識別按下構件21的位置及與其他構件的關係的方式進行了示意性表示。圖5A示出了按下構件21未自外部接受按壓而位於上側的第一位置的狀態，圖5B示出了按下構件21自外部受到按壓而位於下側的第二位置的狀態。The function of the micro switch 2 of the first embodiment described in the present application configured as described above will be described. 5A and 5B are schematic enlarged cross-sectional views showing an example of a part of the cross section of the micro switch 2 described in the present application. FIGS. 5A and 5B are enlarged cross-sections centered on the pressing chamber 25 of the micro switch 2 and schematically show the position of the pressing member 21 and the relationship with other members. FIG. 5A shows a state where the pressing member 21 is located at the first position on the upper side without being pressed from the outside, and FIG. 5B illustrates a state where the pressing member 21 is pressed from the outside and located at the second position on the lower side.

具有本申請案所記載的微開關2的滑鼠等操作裝置1存在於結構上產生間隙的情況。即便自操作裝置1的間隙進入了線頭等異物，由於微開關2藉由框體20保護，接點室24被收容於框體20內，因此異物不易侵入至接點室24內。即，接點室24成為閉合結構，抑制了因異物附著於接點室24內的構件而導致的接觸不良等不良狀況的產生。以下，對操作裝置1內進入了異物的狀況進行假設，一面設想異物侵入至接點室24為止的路徑，一面對微開關2的防塵功能進行說明。The operating device 1 such as a mouse having the micro switch 2 described in the present application may have a gap in the structure. Even if foreign objects such as thread stubs enter from the gap of the operating device 1, since the micro switch 2 is protected by the housing 20 and the contact chamber 24 is housed in the housing 20, the foreign matter is unlikely to intrude into the contact chamber 24. That is, the contact chamber 24 has a closed structure, and the occurrence of defects such as poor contact caused by foreign matter adhering to the members in the contact chamber 24 is suppressed. Hereinafter, assuming that a foreign object enters the operating device 1, a path through which the foreign object enters the contact chamber 24 is assumed, and the dustproof function of the micro switch 2 is described.

在接點室24的上部開設有供按下構件21的插通部213插通的插通孔250，但如圖5A、圖5B等所示，被按下構件21的遮蔽部210遮蔽，因此，異物不易自插通部213與插通孔250之間的若干間隙而進入至接點室24內。The upper part of the contact chamber 24 is provided with an insertion hole 250 through which the insertion portion 213 of the pressing member 21 is inserted. However, as shown in FIGS. 5A and 5B, it is shielded by the shielding portion 210 of the pressing member 21. Therefore, it is difficult for foreign matter to enter the contact chamber 24 from the gaps between the insertion portion 213 and the insertion hole 250.

而且，如圖5A及圖5B所例示，在與框體20的插嵌口200接近的遮蔽部210的左右方向的緣部，形成有朝下方（框體20的內側）突出的外壁部210b，因此如圖5A所示，即便在按下構件21位於上側的第一位置的情況下，外壁部210b的下端亦位於比作為框體20的上表面的插嵌口200低的位置。即，與插嵌口200接近的遮蔽部210的緣部的下端（成為框體20的內側的前端的內端）在按下構件21位於第一位置的情況下，位於插嵌口200的下側（框體20的內部側）。藉此，在按下構件21上升的情況下，遮蔽部210的下端亦不會上升至插嵌口200之上，從而防止了附著於框體20的上表面的異物穿過遮蔽部210的下方而進入至按下室25內。Furthermore, as illustrated in FIGS. 5A and 5B, an outer wall 210b protruding downward (inside of the frame 20) is formed at the edge of the shielding portion 210 in the left-right direction close to the insertion slot 200 of the frame 20. Therefore, as shown in FIG. 5A, even when the pressing member 21 is located at the first position on the upper side, the lower end of the outer wall portion 210 b is located at a lower position than the insertion slot 200 which is the upper surface of the frame body 20. That is, the lower end of the edge of the shielding portion 210 (the inner end that becomes the front end of the inner side of the frame body 20) close to the insertion slot 200 is located below the insertion slot 200 when the pressing member 21 is in the first position. Side (the inner side of the housing 20). Thereby, when the pressing member 21 is raised, the lower end of the shielding portion 210 will not rise above the insertion slot 200, thereby preventing foreign matter attached to the upper surface of the frame body 20 from passing under the shielding portion 210 And enter into the press room 25.

進而，如圖5B所示，在按下構件21位於下側的第二位置的情況下，外壁部210b的下端（相對於框體20而言為內端）下降至按下室25內的底面附近。即便在按下構件21位於下側的第二位置的情況下，遮蔽部210的上表面的位置相對於框體20的上表面而言，亦位於同等或上側的位置，因此不會在框體20的上表面產生凹陷而滯留異物。Furthermore, as shown in FIG. 5B, when the pressing member 21 is located at the second lower position, the lower end of the outer wall portion 210b (the inner end with respect to the frame 20) is lowered to the bottom surface of the pressing chamber 25 nearby. Even when the pressing member 21 is located at the second position on the lower side, the position of the upper surface of the shielding portion 210 is at the same or upper position relative to the upper surface of the frame body 20, so it will not be in the frame body. The upper surface of 20 is dented and foreign matter is retained.

即便異物自按下構件21與框體20的間隙進入到了按下室25內，由於在插通孔250的周圍形成有內壁部251，因此進入至按下室25內的異物不易越過內壁部251而自插通部213與插通孔250之間的間隙進入至接點室24內。Even if foreign matter enters the pressing chamber 25 from the gap between the pressing member 21 and the frame 20, the inner wall portion 251 is formed around the insertion hole 250, so the foreign matter entering the pressing chamber 25 cannot easily pass the inner wall. The portion 251 enters the contact chamber 24 from the gap between the insertion portion 213 and the insertion hole 250.

另外，認為：若為大於或等於0.1 mm的異物，則藉由進入至接點室24內而引發異常的可能性變大。因此，理想的是將開設於框體20的插嵌口200與遮蔽部210的間隙，以及開設於框體20內的按下室25的底面的插通孔250與插通部213的間隙設為小於0.1 mm。而且，為了防止進入至按下室25內的異物進入至接點室24內，內壁部251的高度理想的設為大於或等於0.1 mm即比插嵌口200與遮蔽部210的緣部的間隙長。除此之外，藉由將按下構件21、框體20等各種構件間產生的間隙設計為恰當的大小，亦能夠抑制異物侵入至接點室24內。In addition, it is considered that if it is a foreign object greater than or equal to 0.1 mm, it is more likely to cause an abnormality by entering the contact chamber 24. Therefore, it is desirable to provide the gap between the insertion slot 200 and the shielding portion 210 opened in the frame 20 and the gap between the insertion hole 250 and the insertion portion 213 on the bottom surface of the pressing chamber 25 opened in the frame 20 It is less than 0.1 mm. Furthermore, in order to prevent foreign matter entering the pressing chamber 25 from entering the contact chamber 24, the height of the inner wall portion 251 is desirably set to be greater than or equal to 0.1 mm, that is, greater than the edge of the insertion slot 200 and the shielding portion 210. The gap is long. In addition, by designing the gaps generated between various members such as the pressing member 21 and the frame 20 to an appropriate size, it is also possible to prevent foreign matter from entering the contact chamber 24.

如上所述，本申請案所記載的微開關2防塵性高，即便在異物進入到了操作裝置1內的情況下，進入的異物亦不易侵入至微開關2的接點室24內。藉此，起到能夠抑制因侵入的異物導致的異常，例如動作不良的產生等優異的效果。As described above, the microswitch 2 described in the present application has high dust resistance, and even when foreign objects enter the operating device 1, the foreign objects do not easily enter the contact chamber 24 of the microswitch 2. Thereby, there is an excellent effect of being able to suppress abnormalities caused by intruding foreign objects, such as malfunctions.

另外，本申請案所記載的微開關2的效果不僅僅是防塵效果。例如，微開關2所具有的按下構件21可在組裝了框體20內部的構成後，自框體20的外側嵌入，所以與在框體20內裝配按下構件21的情況相比，組裝更容易。因此，本申請案所記載的微開關2起到可期待與組裝步驟相關的效率化、良率的提升等效果之類的優異效果。In addition, the effect of the micro switch 2 described in this application is not only the dustproof effect. For example, the pressing member 21 of the micro switch 2 can be fitted from the outside of the frame 20 after the internal structure of the frame 20 is assembled. Therefore, compared with the case where the pressing member 21 is assembled in the frame 20, the assembly Easier. Therefore, the microswitch 2 described in the present application has excellent effects such as effects such as efficiency improvement and yield improvement related to the assembly process.

進而，微開關2的按下構件21中，形成於按下構件21的遮蔽部210的緣部的外壁部210b被以空開若干間隙的方式插嵌於插嵌口200，並在框體20的前後的面亦刻製有引導槽201。藉此，在按下構件21受到按壓的情況下，插通部213不會傾斜而是筆直地***至插通孔250。因此，起到能夠抑制按下時的操作不良及動作不良的產生等優異的效果。Furthermore, in the pressing member 21 of the micro switch 2, the outer wall portion 210b formed on the edge of the shielding portion 210 of the pressing member 21 is inserted into the insertion slot 200 with a certain gap, and is inserted in the frame 20 Guide grooves 201 are also engraved on the front and back surfaces of the slab. Thereby, when the pressing member 21 is pressed, the insertion portion 213 is inserted straight into the insertion hole 250 without being inclined. Therefore, there is an excellent effect of being able to suppress the occurrence of malfunctions and malfunctions during pressing.

＜第2實施方式＞ 第2實施方式是在第1實施方式中，去除了形成於按下室25的插通孔250的周圍的內壁部251及形成於按下構件21的遮蔽部210的外壁部210b的構成。另外，在以下的說明中，針對與第1實施方式相同的構成，標注與第1實施方式相同的符號，以第1實施方式為參照而省略其說明。<Second Embodiment> In the second embodiment, in the first embodiment, the inner wall portion 251 formed around the insertion hole 250 of the pressing chamber 25 and the outer wall portion 210b formed on the shielding portion 210 of the pressing member 21 are removed.
