  On the other hand, in order to make the decoration by illumination of the key top more effective decoration, it is required to illuminate only the vicinity of the outer periphery of the top surface of the key top in a ring shape. In order to illuminate only the outer peripheral part of the top surface of the key top in a ring shape, for example, a shielding part made of non-transparent paint is applied to the central part of the top surface of the key top, and only the periphery of the key top is provided by this shielding part. The method of illuminating is generally used. In recent years, for the purpose of further effective decoration of the key top, there is a case in which a deposited film is formed by sputtering or the like instead of painting or printing as a shielding portion of the central portion of the key top. When a shielding part made of a deposited film is used, a high-grade metallic color can be obtained.

However, the deposited film by sputtering may not be formed well depending on the material compatibility depending on the material of the transparent key top such as PMMA resin. Further, even in the case of a shielding part by a method other than vapor deposition by sputtering (for example, printing or the like), depending on the material of the transparent key top, the formation thereof may not be successfully performed.

The lower surface is configured as a contact surface 95 by bending 90 ° in the opposite direction. A central opening 96 of the ground plate 90 is circular.

  The key top body 100 is made of a light-transmitting synthetic resin (for example, PMMA resin), and is configured to cover the upper portion of the substantially cylindrical side wall portion 101 with the upper surface 103. A tongue-shaped guide protrusion 105 projects from the position of the lower outer periphery of the side wall 101 facing 180 ° outwardly in the radial direction, and the shielding member storage section 107 is recessed in a circle at the center of the upper surface 103.

Both attachment fixing portions 111 are provided at positions facing both attachment portions 63 of the pressing plate 60.

  The shielding member 120 is formed by molding a non-translucent synthetic resin (for example, ABS resin) into a substantially disc shape, and a pair of cylindrical locking portions 121 (on the front side in FIG. (Only one is shown). Each locking portion 121 is provided at a position facing the opening 109 of the key top body 100 with an outer diameter dimension inserted into the opening 109. A metal vapor deposition film is formed on at least the upper surface of the shielding member 120 by sputtering. In this embodiment, aluminum (Al) is used as the material of the vapor deposition film, but other various vapor deposition materials such as tin (Sn) may be used (the same applies to vapor deposition films formed on other members). In this embodiment, the ABS resin is used as the shielding member 120 because it is easy to form a vapor deposition film. As described above, it is not easy to form a vapor deposition film on the surface of the PMMA resin constituting the key top body 100 due to the compatibility of both.

  First, a method for assembling the key top 50 for the push switch will be described. First, the shielding member 120 is accommodated in the shielding member accommodating portion 107 of the key top body 100, and at that time, the pair of locking portions 121 of the shielding member 120 are disposed.

At this time, both contact portions 93 which are the peripheral portions of the ground plate 90 are in contact with the ground pattern on the upper surface of the second ground substrate 80, and the top and bottom of the ground plate 90 and the second ground substrate 80 are in contact with the key top body 100. The structure is sandwiched between the pressing plate 60. Further, the contact portion 93 of the ground plate 90 is positioned so as to be directly below the guide protrusion 105 of the key top body 100.

  Next, the fixing member 150 and the swing knob 190 are connected by the connecting member 210. That is, the connecting member 210 is disposed on the fixing member 150, and at this time, each connecting portion 159 of the fixing member 150 is inserted into each mounting hole 215 of the connecting member 210, and each connecting portion 159 protruding to the upper surface side of the connecting member 210. Clamp the parts and fix them together. Next, the connecting member 210 to which the fixing member 150 is attached is disposed on the lower surface of the swing knob 190, and at this time, each pressing portion 193 of the swing knob 190 is inserted into each attachment portion 217 of the connection member 210. The fixing portions 195 projecting to the lower surface side of the rim are heat-caulked to fix them together. As a result, the swing knob 190 is swingably attached to the fixed member 150.

  Then, the swing knob 190 to which the fixing member 150 and the connecting member 210 are attached is stored in the electronic component storage portion 233 from the lower surface side of the case 230, and the upper portion of the swing knob 190 projects from the opening 235. At the same time, the insertion protrusions 237 protruding from the lower surface of the case 230 are inserted into the insertion holes 163 of the fixing member 150 to penetrate therethrough. Next, the assembled pressure switch key top 50 is inserted into the key top storage portion 153 from the lower surface side of the fixing member 150, and at this time, the pair of guide protrusions 105 of the key top body 100 are inserted into the key top storage portion 153. Inserted into the pair of guide grooves 155 so as to be movable up and down. The mounting plate 10 on which the first ground board 40 and the switch circuit board 20 are placed is disposed on the lower surface of the case 230, and each insertion of the case 230 that passes through each insertion hole 163 of the fixing member 150 at that time. The protrusion 237 and the locking portions 161 of the fixing member 150 are connected to the insertion portions 41, 42, 43, 44 of the first ground substrate 40 and the insertion portions 25, 26, 27, 28 of the switch circuit substrate 20, respectively. It inserts in each engaging part 11, 12, 13, 14 of the attachment board 10, and fixes the front-end | tip of each insertion protrusion 237 of the said case 230 which protruded on the lower surface of the attachment board 10 with heat caulking.

  As a result, the swingable electronic component 1 with illuminated pressing electronic component shown in FIG. 1 is completed. As shown in FIG. 1, the illumination mechanism of the key top 50 for the pressure switch in the oscillating electronic component 1 with the illumination-type pressure electronic component includes a pressure plate 60 that presses the pressure switch 21 on the central pressure switch 21. By installing the light emitting element 77 on the pressing plate 60, attaching the translucent key top body 100 covering the upper part of the light emitting element 77, and attaching the shielding member 120 to the center of the upper surface of the key top body 100. It is configured. Here, the shielding member 120 is attached to the key top main body 100 by inserting the locking portion 121 provided on the shielding member 120 into the opening 109 penetrating in the vertical direction provided on the upper surface 103 of the key top main body 100. Has been done. Further, a ground plate 90 for grounding static electricity entering the key top body 100 is installed at a position surrounding the light emitting element 77 on the pressing plate 60 (specifically, an upper position around the light emitting element 77). More specifically, in addition to the ground plate 90, the ground mechanism is installed at a position surrounding the light emitting element 77 on the pressing plate 60 (specifically, a substantially same plane position surrounding the light emitting element 77). A ground substrate 80 provided with a ground pattern on the surface thereof is provided. In addition, the swinging electronic component 1 with the illumination type pressing electronic component is provided with a swinging knob 190 having an opening 191 through which the key top body 100 is inserted, and operating (swinging) the swinging knob 190. By providing an electrical function part (consisting of a pressing part 193 and a pressing switch 23) that changes the electrical output (on / off output), a central pressing switch 21 (or a pressing switch key top 50 on the pressing switch 21) is provided. In addition, another electronic component (oscillating electronic component) is installed around the illumination type pressing electronic component including

  In the swingable electronic component 1 with the illumination-type pressing electronic component configured as described above, if the upper surface of the pressing switch key top 50 (that is, the upper surface of the shielding member 120) is pressed, the entire pressing switch key top 50 is provided. Is lowered, and the pressing portion 61 provided on the pressing plate 60 presses the pressing switch 21 to reverse the reversing plate 23A to turn it on. When the pressing to the pressing switch key top 50 is released, the reversing plate 23A automatically returns to its original shape, and the pressing switch 21 is turned off. On the other hand, since the swing knob 190 is supported so as to be swingable in each direction with respect to the fixed member 150 via the connecting member 210, when a predetermined portion on the upper surface of the swing knob 190 is pressed, a pressure just below the pressed portion is pressed. The part 193 presses one of the pressure switches 23 facing the part 193 to reverse the reversing plate 23A and turn it on. When the pressing on the swing knob 190 is released, the reversing plate 23A automatically returns to its original shape, and the pressing switch 23 is turned off.

  On the other hand, when the light emitting element 77 emits light, the light is irradiated into the key top body 100 through the opening 96 provided in the ground plate 90, and the upper surface of the key top body 100 around the shielding member 120 not covered by the shielding member 120. The key top body 100 is brightly illuminated like a ring.

  By the way, when a charged finger or the like approaches or touches the upper surface of the key top 50 for the pressing switch or the swing knob 190, the static electricity is generated between the shielding member 120 and the upper surface 103 of the key top body 100 and between the locking portion 121 and the opening. Through a slight gap between 109, the light reaches the light receiving element 77 inside the key top body 100. However, the static electricity is discharged to the ground plate 90 located above the light emitting element 77 and led out to the ground through the ground pattern of the ground substrate 80 to be grounded. Therefore, there is no possibility that the static electricity enters the light emitting element 77 and the circuit pattern on the circuit board 70 connected thereto. Note that static electricity that attempts to enter the outer peripheral portion of the circuit board 70 along the outer peripheral surface of the key top body 100 from the gap between the opening 191 of the swing knob 190 and the key top main body 100 is surrounded by the outer peripheral upper surface of the circuit board 70. Therefore, the static electricity does not directly enter the circuit pattern of the circuit board 70. In addition, static electricity that enters from the gap between the opening 191 of the swing knob 190 and the key top body 100 or the gap between the opening 235 of the case 230 and the swing knob 190 toward the switch circuit board 20 is generated by the switch circuit board 20. Since it is grounded by the ground pattern of the ground substrate 40 covering the top, static electricity does not enter the circuit pattern on the switch circuit board 20.

  In the above embodiment, the shielding member 120 that covers the center of the upper surface is attached as a separate component from the key top main body 100. As described above, the material of the transparent key top main body 100 (for example, PMMA resin) is directly deposited by sputtering. This is because it cannot be performed well due to the nature of the material. For this reason, a shielding member 120 made of a material (for example, ABS resin) that can be easily deposited is attached separately. In this embodiment, in order to ensure that the shielding member 120 is attached to the key top body 100, the locking portion 121 provided in the shielding member 120 is provided in the opening 109 penetrating vertically in the upper surface 103 of the key top body 100. It is structured to insert and attach. With such a structure, there is a risk that static electricity may enter from the gap of the opening 109 as described above, but a ground mechanism is provided to eliminate this inconvenience. In order to prevent a gap from being formed in the opening 109, the key top main body 100 is formed in a mold that incorporates the shielding member 120 by changing two parts, that is, a part of the mold in which the shielding member 120 is molded. A method of forming the film may be used. If comprised in this way, between the keytop main body 100 and the shielding member 120 will be closely_contact | adhered, a clearance gap will not arise, and static electricity will not penetrate | invade between both. However, when two-material molding is used, after the two-material molding is performed and the key top body 100 and the shielding member 120 are integrally molded, a vapor deposition process by sputtering is separately performed only on the surface of the shielding member 120. Compared with the step of mechanically attaching the surface of the single shielding member 120 formed in advance to the key top main body 100 as in the embodiment, the entire manufacturing process becomes complicated. Moreover, the metal mold | die used for two-material shaping | molding is expensive. Therefore, in the above embodiment, the shielding member 120 is mechanically attached to the key top main body 100 without using the two-material molding, and instead enters the key top main body 100 through the gap of the opening 109. The configuration is such that static electricity is removed by an earth mechanism constituted by the earth plate 90 or the like. In the above embodiment, the attachment structure in which the locking portion 121 provided in the shielding member 120 is attached to the opening 109 provided in the key top main body 100 by heat caulking is shown. Mounting structure by so-called snap-in engagement, etc., in which a claw is provided at the tip and the claw at the tip of the locking part 121 inserted into the opening 109 of the key top body 100 is locked to the lower surface of the opening 109, etc. Various mounting structures may be used.

For example, in the above-described embodiment, the main body 91 made of a ring-shaped flat plate of the ground plate 90 is placed above the light emitting element 77 on the pressing plate 60 by a predetermined dimension so as to surround the light emitting element 77 in a ring shape. The shape of the plate 90 can be variously modified. For example, the outer periphery of the main body 91 made of a ring-shaped flat plate may be extended downward in a cylindrical shape to provide a side wall. The point is that the ground plate 90 may have any shape and structure that allows the static electricity entering the key top body 100 to enter and ground.
