Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. <Application Example> The operating device disclosed in this application is used, for example, as an operating device such as a mouse for operating a personal computer (hereinafter referred to as a personal computer). In addition, the switch disclosed in this application is incorporated as a microswitch into various electronic devices including the operating device. The switch is incorporated into the operating device as a switch assembly (hereinafter referred to as a switch unit) mounted on a substrate. Hereinafter, the operating device 1 and the switch 2 illustrated in the accompanying drawings, and further the switch unit 4 in which the switch 2 is mounted on the substrate 3 will be described with reference to the accompanying drawings. <Operating Device 1> First, the operating device 1 will be described. FIG. 1 is a schematic perspective view showing an example of the appearance of the operating device 1 disclosed in the present application. FIG. 1 shows an example of a mouse used in the operation of an electronic device such as a personal computer to which the operating device 1 disclosed in the present application is applied. The operating device 1 includes: a pressing operation unit 10 such as a mouse button that receives an operation pressed by a user's finger, and a rotating operation unit 11 such as a mouse wheel that receives an operation rotated by a user's finger. In addition, the rotating operation unit 11 is configured to receive not only a rotating operation but also a pressing operation, and also functions as the pressing operation unit 10. Further, in the operating device 1, a signal line 12 for outputting an electrical signal to an external device such as a personal computer is connected. In addition, the operating device 1 is not limited to wired communication using the signal line 12, and can output an electrical signal by various communication methods such as wireless communication. The operating device 1 houses the switch 2 described below as a switch assembly 4 inside in accordance with each of the pressing operation unit 10 and the rotating operation unit 11. In the operating device 1, when an operator performs a pressing operation on the pressing operation unit 10, the pressing operation unit 10 presses the corresponding switch 2 through an internal part (not shown). The switch 2 outputs a signal based on the pressing from the signal line 12 to an external electronic device such as a personal computer. Thus, the operating device 1 disclosed in the present application transmits the pressing operation received by the pressing operation unit 10 and / or the rotating operation unit 11 in the form of an external pressing to the switch 2, and outputs a signal based on the operation of the switch 2 from the signal line 12 to an external electronic device. <Structure of Switch Assembly 4 and Switch 2> Next, the switch assembly 4 and the switch 2 disclosed in the present application will be described. FIG. 2 is a schematic perspective view showing an example of the appearance of the switch assembly 4 disclosed in the present application. In addition, in the present application specification, regarding the direction of the switch 2, the position near the front left side when viewed from the front in FIG. 2 is referred to as the front, the right inner side is referred to as the rear, the left inner side is referred to as the left, the right near the front side is referred to as the right, the upper side is referred to as the upper, and the lower side is referred to as the lower, but it is a direction for convenience of explanation and does not limit the assembly direction of the switch 2. As described above, the switch assembly 4 is housed inside an electronic device such as the operating device 1 and receives the pressing operation received by parts such as the pressing operation unit 10 of the operating device 1 in the form of an external pressing. The switch assembly 4 is constituted by mounting a switch 2 such as a microswitch on a resin substrate 3 on which various circuits, components, and wirings are formed. The switch 2 includes a frame body 20 having a substantially rectangular parallelepiped shape. On the upper surface of the frame body 20, a rectangular insertion hole 200 for inserting a pressing member 21 is provided at a position left of the center when viewed from the front. The pressing member 21 inserted into the insertion hole 200 is a member that moves up and down within a range from the upper limit position to the lower limit position of the movement range when pressed from the outside of the frame body 20. The upper end of the pressing member 21 protrudes from the upper surface of the frame body 20. The switch 2 formed in this way transmits the pressing operation performed by the operator received by the pressing operation part 10 of the operating device 1 to the pressing member 21 in the form of a pressing force from the outside of the housing 20. The pressing member 21 moves from the upper limit position to the lower limit position under the pressing force from the outside, and moves from the lower limit position to the upper limit position when the pressing force from the outside is released. Next, the internal structures of the switch assembly 4 and the switch 2 will be described. FIG. 3 is a schematic exploded perspective view showing an example of the switch assembly 4 disclosed in the present application. FIG. 4 is a schematic perspective view showing an example of the switch 2 disclosed in the present application. FIG. 5 is a schematic cross-sectional view showing an example of the switch 2 disclosed in the present application. FIG. 4 shows the inside visually recognizable from the viewpoint of the lower right oblique direction by removing the upper cover 20a included in the housing 20. FIG. 5 shows a cross-section cut by a vertical plane passing through the line segment A-B in FIG. 2 from the front viewpoint. The substrate 3 is formed in a substantially rectangular flat plate shape and has a substantially flat mounting surface 30 on which the switch 2 is mounted. In the illustrated example of the substrate 3, the mounting surface 30 is the upper surface. In order to fix the mounted switch 2, the substrate 3 is formed with a plurality of mounting holes 31 penetrating vertically. On the mounting surface 30 of the substrate 3, a thin plate electrode 32 for surface-mounting various components is mounted. The housing 20 included in the switch 2 has a substantially rectangular parallelepiped box shape, and the lower surface becomes the outer bottom surface 202 that abuts against the mounting surface 30 when mounted on the substrate 3. The housing 20 is formed by the upper cover 20a and the lower base 20b. The upper cover 20a is a substantially rectangular parallelepiped box with an open lower surface, and the lower surface is closed by the base 20b. In the housing 20 of the switch 2, a space for the accommodation chamber 203 for accommodating various components required for opening and closing the electrical circuit is ensured. In the accommodation chamber 203 of the housing 20, various components such as a support member 22, a movable member 23, and an optical member 24 are accommodated in addition to the pressing member 21. The housing 20 accommodates a light-emitting member 24a and a light-receiving member 24b as the optical member 24. An insertion hole 200 is formed in the upper surface of the cover 20a, which is the ceiling of the accommodation chamber 203, and the pressing member 21 is inserted through the insertion hole 200. The base 20b of the housing 20 is formed with a fixing portion 201 for fixing the support member 22 on the inner bottom surface located in the accommodation chamber 203. The lower surface of the base 20b forms the outer bottom surface 202 of the housing 20 having a substantially rectangular parallelepiped shape. When the switch 2 is mounted on the mounting surface 30 of the substrate 3, the outer bottom surface 202 of the housing 20 is fixed in a state of being in contact with the mounting surface 30 of the substrate 3. In the housing 20, a boss portion 204, a pair of locking portions 205, and a pair of holding portions 206 that protrude more downward than the outer bottom surface 202 are formed at the lower portion of the base 20b. When the switch 2 is mounted on the substrate 3, the boss portion 204, the pair of locking portions 205, and the pair of holding portions 206 formed on the base 20b of the housing 20 are respectively inserted into the mounting holes 31 of the substrate 3. The boss portion 204 has a substantially cylindrical shape with its central axis in the vertical direction, and is formed to protrude downward from a position slightly to the left of the center of the outer bottom surface 202. The boss portion 204 is inserted into the substantially circular mounting hole 31 formed in the substrate 3 for positioning the mounting position of the switch 2. The pair of locking portions 205 are respectively formed to extend downward from positions on the left and right of the outer bottom surface 202 sandwiching the boss portion 204, and their lower ends are bent toward the boss portion 204 to form a snap structure. The pair of locking portions 205 are inserted into the mounting holes 31 of the substrate 3 and are used for fixing the switch 2 through the snap structure. The pair of holding portions 206 are portions for holding the optical members 24 arranged in the front and rear directions near the right end of the substrate 3. In order to surface-mount the optical members 24 on the thin-film electrodes 32 of the mounting surface 30 of the substrate 3, the pair of holding portions 206 are formed in a shape where a part protrudes more downward than the mounting surface 30, so that the contact surface 240, which is the lower surface of the optical member 24, is coplanar with the outer bottom surface 202 of the switch 2 and is in contact with the mounting surface 30 of the substrate 3. The housing 20 is formed with a light-emitting holding portion 206a for holding the light-emitting member 24a of the optical member 24 and a light-receiving holding portion 206b for holding the light-receiving member 24b of the optical member 24 in the front and rear directions as the pair of holding portions 206, and a gap for the movable member 23 is ensured between the light-emitting holding portion 206a and the light-receiving holding portion 206b. A more detailed description will be given of the shape of the holding portion 206 formed on the housing 20 and the optical member 24. FIG. 6 is a schematic perspective view showing an enlarged part of the switch 2 disclosed in the present application. FIG. 7 is a schematic cross-sectional view showing an enlarged part of the switch 2 disclosed in the present application. FIGS. 6 and 7 show an enlarged view of the holding portion 206 formed on the housing 20, the optical member 24 held by the holding portion 206, and their vicinity. FIG. 7 shows a cross-section in a state where the switch 2 is mounted on the substrate 3. The holding portion 206 of the housing 20 is not limited to a state of completely fixing the optical member 24, and may be formed to hold it with some play, but it is preferably held to suppress movement in directions other than the optical axis direction (the front-rear direction in FIG. 5) (the up-down and left-right directions in FIG. 5). The switch 2 disclosed in the present application can maintain accuracy and responsiveness even in a state where the output of light emission and light reception of the optical member 24 is suppressed by stabilizing the position in the optical axis direction. The optical axis direction in the present application indicates the direction of the irradiated light, and in the case of installation, it means the so-called structural axis, but it can also be the direction of an axis based on other definitions such as the optical axis and the maximum luminous intensity axis. When assembling the switch 2, the optical member 24 (light emitting member 24a, light receiving member 24b) is assembled by inserting it in the optical axis direction into the holding portion 206 (light emitting holding portion 206a, light receiving holding portion 206b). When mounting the switch 2 on the substrate 3, the holding portion 206 of the housing 20 holds the optical member 24 so that the contact surface 240 of the optical member 24 and the outer bottom surface 202 of the housing 20 are in contact with the mounting surface 30 of the substrate 3 in a substantially coplanar manner. The optical member 24 of the switch 2 having a flat and substantially rectangular shape becomes a concave electrode 241 whose lower left and right edges are cut into a concave curved surface shape. When surface-mounting the thin-film electrode 32 formed on the contact surface 240 of the substrate 3, solder is applied to the concave electrode 241 of the optical member 24. Since the optical member 24 applies solder to the concave electrode 241 cut into a concave curved surface shape, the contact surface 240 can be surface-mounted while maintaining contact with the mounting surface 30 of the substrate 3. Returning to FIGS. 3, 4, and 5, various members housed in the housing chamber 203 of the housing 20 will be described. The support member 22 is a member that supports the movable member 23 so that it can operate, and is fixed to the housing chamber 203 by the fixing portion 201 of the housing 20. The support member 22 is a substantially U-shaped member that connects a first support portion 220 erected on the left side in the housing chamber 203 and a second support portion 221 erected substantially in the center in the housing chamber 203 through a connecting portion 222 fixed to the lower part of the housing chamber 203 by the fixing portion 201. The movable member 23 is a member supported by the support member 22 in the accommodation chamber 203 and operated by the pressing of the pressing member 21. The movable member 23 includes a movable piece 230 formed of a flexible metal thin plate, and a shielding plate 231 that transmits / shields the light emitted from the light-emitting member 24a. The movable piece 230 is arranged such that the longitudinal direction is the left-right direction in the accommodation chamber 203. The left end side of the movable piece 230 is a fixed end supported by the first support portion 220 of the support member 22, and serves as a swing fulcrum when the movable member 23 performs a swinging motion. The right end side of the movable piece 230 is a free end, and the shielding plate 231 is mounted thereon. Near the center of the movable piece 230, it is pressed into a tongue shape, and a biasing portion 2300 that functions as an arcuate return spring is formed. The biasing portion 2300 is connected to the outside pressed on the right end side, and the left end side is cut off. The left end side of the biasing portion 2300 formed on the movable piece 230 is supported by the second support portion 221 of the support member 22. The movable piece 230 is supported by the support member 22 so that the biasing portion 2300 is deformed into an arc shape, and thus the biasing portion 2300 functions as a leaf spring. The biasing portion 2300 generates a reaction force that overcomes the pressing of the pressing member 21. The upper part of the shielding plate 231 of the movable member 23 is a portion that can be mounted on the movable piece 230, and extends in a substantially rectangular plate shape from the upper part downward. The shielding plate 231 is mounted on the movable piece 230 at the upper part such that the normal direction of the plate-shaped portion is the optical axis direction (front-rear direction) of the optical member 24. The shielding plate 231 is arranged to be located between the light-emitting member 24a and the light-receiving member 24b of the optical member 24. The shielding plate 231 is provided with a through window 2310 having a substantially rectangular shape through which the light emitted from the optical member 24 passes. The optical member 24 is a member held by the holding portion 206 in the accommodation chamber 203, and includes a light-emitting member 24a held by the light-emitting holding portion 206a and a light-receiving member 24b held by the light-receiving holding portion 206b. The optical member 24 is formed in a substantially flat shape, and the lower surface is substantially flat and is a contact surface 240 that is surface-mounted in a state of being in contact with the mounting surface 30 of the substrate 3. The light-emitting member 24a emits light, and the light-receiving member 24b receives the light emitted from the light-emitting member 24a. The light-emitting member 24a is composed of a light-emitting element such as an LED (Light Emitting Diode), and the light-emitting portion protrudes in the optical axis direction. The light-receiving member 24b is composed of a light-receiving element such as a PD (Photo Diode) or a PT (Photo Transistor) for detecting light, and the light-detecting portion protrudes in the optical axis direction. The light-emitting member 24a and the light-receiving member 24b are respectively held by the light-emitting holding portion 206a and the light-receiving holding portion 206b such that the optical axes are aligned, and are arranged facing each other on the substrate 3. <Operation of Switch 2> Next, the opening and closing of the circuit in Switch 2 disclosed in the present application will be described. FIGS. 8 and 9 are schematic cross-sectional views showing an example of Switch 2 disclosed in the present application. FIG. 8 shows a cross-section cut by a vertical plane passing through line segment A-B shown in FIG. 2 from a front view point, and FIG. 9 shows a cross-section cut by a vertical plane passing through line segment C-D shown in FIG. 2 from a right view point. FIGS. 8 and 9 show a state where the pressing member 21 is not pressed from the outside and is located at the upper limit position of the movement range. In the state where the pressing member 21 illustrated in FIGS. 8 and 9 is located at the upper limit position, the optical path between the light emitting member 24a and the light receiving member 24b is blocked by the shielding plate 231 of the movable member 23. Therefore, the light emitted from the light emitting member 24a is blocked by the shielding plate 231. FIG. 10 is a schematic cross-sectional view showing an example of Switch 2 disclosed in the present application. FIG. 10 shows a state where the pressing member 21 is pressed from the state shown in FIG. 8 and moves to the lower limit position of the movement range. In the state where the pressing member 21 illustrated in FIG. 10 is located at the lower limit position, the optical path between the light emitting member 24a and the light receiving member 24b passes through the through window 2310 formed in the shielding plate 231. Therefore, the light receiving member 24b receives the light emitted from the light emitting member 24a. The Switch 2 disclosed in the present application outputs a signal for opening and closing the circuit to an external electronic device based on the shielding / transmission of light by a pressing operation according to the reception state of the light emitted from the light emitting member 24a by the light receiving member 24b. For example, in the open state where the pressing member 21 is located at the upper limit position of the movement range, the light is blocked, so the circuit is in an open state. In addition, in the pressed state where the pressing member 21 is located at the lower limit position of the movement range, the light is transmitted, so the circuit becomes a closed state. As described above, in the Switch 2 disclosed in the present application, the optical members 24 (light emitting member 24a, light receiving member 24b) are held in the housing 20 by the holding portions 206 (light emitting holding portion 206a, light receiving holding portion 206b). The held optical members 24 are surface-mounted on the mounting surface 30 of the substrate 3. Therefore, in the Switch 2 disclosed in the present application, the optical members 24 are positioned by the holding portions 206, so that misalignment during surface mounting can be prevented and the assembly accuracy can be improved. Therefore, the Switch 2 disclosed in the present application can improve the response time and accuracy without increasing the output for light emission, and thus has an excellent effect of being able to suppress power consumption. <Another form of switch 2> Fig. 11 is a schematic exploded perspective view showing an example of switch 2 disclosed in the present application. Fig. 11 shows another form of switch 2 disclosed in the present application. The switch 2 illustrated in Fig. 11 is a form with a different method of incorporating optical member 24. Switch 2 includes structures such as housing 20, pressing member 21, support member 22, movable member 23, and optical member 24. Housing 20 is formed by cover 20a and base 20b. Base 20b is formed with a holding portion 206 having an open upper surface. The bottom surface of support member 22 is formed in a plate shape and serves as a cover for base 20b such as to block the opening of the upper surface of holding portion 206. Fig. 12 is a schematic perspective view showing an enlarged part of switch 2 disclosed in the present application. Fig. 12 shows a state in which optical member 24 is incorporated into holding portion 206 formed in base 20b of housing 20. As illustrated in Fig. 12, switch 2 disclosed in the present application is assembled by inserting optical member 24 (light emitting member 24a, light receiving member 24b) into holding portion 206 from above, that is, from the opposite side of the outer bottom surface orthogonal to the optical axis direction. After incorporating optical member 24 into holding portion 206, the open upper surface of holding portion 206 is closed by covering support member 22. <Another form of switch 2> Fig. 13 is a schematic perspective view showing an example of switch 2 disclosed in the present application. Fig. 13 shows yet another form of switch 2 disclosed in the present application. The switch 2 illustrated in Fig. 13 is a form with a different method of incorporating optical member 24. Fig. 13 shows switch 2 from an obliquely lower direction, showing the state before installing one of optical members 24 and after installing the other. The lower part of holding portion 206 formed in base 20b of housing 20 of switch 2 is open. The cover 20a of housing 20 of switch 2 extends downward and is formed with a locking claw 207 having a bent front end. Locking claw 207 locks optical member 24 held by holding portion 206. Switch 2 disclosed in the present application is assembled by inserting optical member 24 (light emitting member 24a, light receiving member 24b) into holding portion 206 (light emitting holding portion 206a, light receiving holding portion 206b) from below, that is, from the outer bottom surface side orthogonal to the optical axis direction. Optical member 24 incorporated into holding portion 206 is locked by locking claw 207. The present invention is not limited to the various embodiments described above and can be developed into other various forms. Therefore, the above embodiments are merely simple illustrations in all aspects and are not to be construed in a limiting sense. The technical scope of the present invention is defined by the claims and is not restricted by any content in the main body of the description. Furthermore, all modifications and changes within the equivalent scope of the claims are within the scope of the present invention. For example, in the above-described embodiment, a form is shown in which the holding unit 206 holds the light-emitting member 24a in a manner that suppresses movement in a direction other than the optical axis direction. However, the present invention is not limited to this, and various forms such as a form in which movement in the optical axis direction is also suppressed can be developed. In addition, for example, in the above-described embodiment, a form is shown in which the light-emitting member 24a and the light-receiving member 24b are arranged facing each other.
