The first light guiding portion 51 has a trapezoidal plate shape, and the free end is disposed directly above the light emitting member 20, and an arc-shaped light incident opening 511 is further provided on the end surface of the free end. In the present embodiment, the first light guiding portion form number A0101 4th/15 pages 0992018458-0 201135783 ❹ 51 intersects the second light guiding portion 52 to form a reflecting surface toward the free end of the first light guiding portion 51. 512 'Reflecting surface 51 2 reflects the light beam entering the first 'light portion 51 from the light entrance 511 to the second light guiding portion 52; please refer to FIG. 3 together, the first V light portion 52 and the third light guiding portion The intersection of the 53 faces forms a reflection surface 523 facing the reflection surface 512, and the reflection surface 523 reflects the light beam incident from the first light guiding portion 51 into the second light guiding portion 52 to the third light guiding portion 53. In order to reduce the beam path of the beam as much as possible and reduce the loss of the beam incident on the reflecting surfaces 51, 523, the first light guiding portion 51 and the second light guiding portion 52, the second light guiding portion 52 and The three light guiding portions 53 are orthogonal to each other, and the reflecting surfaces 512 and 523 are formed 45 with the second light guiding portion 52, respectively. Angle and polished. The second light guiding portion 52 is further provided with a positioning hole 521 which cooperates with the positioning post 641. The second light guiding portion 53 has an elongated plate shape conforming to the shape of the through hole 63 on the button 60, and the first light guiding portion 53 is away from the first A bearing portion 531 extends vertically in the direction of a light guiding portion 51. During assembly, the positioning post 641 passes through the positioning hole 521, the third light guiding portion 53 passes through the through hole 63 of the button 60 and abuts against the pressing portion 62, and the receiving portion 531 extends into the receiving cavity 621 and is opposite to the reinforcing rib 622. The second light guiding portion 52 is pressed against the fixing portion 61, and the button 60 and the light guiding member 50 are assembled by a hot melt connection between the positioning post 641 and the positioning hole 521. In order to enable the light guiding member 5 to guide light, the material of the light guiding member 50 is polycarbonate (p〇iyear>bc)nate, referred to as PC) or polymethyl methacrylate (PMMA). . The base 40 has a plate shape and includes a fixing portion 41 and a support block 42 extending perpendicularly from the surface of the fixing portion 41_. The fixing portion 41 is provided with a positioning hole 413 which cooperates with the positioning post 641 and a positioning hole 414 which cooperates with the positioning jaw 642. The branch block 42 is disposed at the center of the fixing portion 41, and the support block 42 faces the positioning hole 413 099110476 A0101 ^ 5 15 1 0992018458-0 201135783] The support slope 45 of the surface t is 45 degrees. Referring to FIG. 4 together, a contact 43 is vertically extended from the middle of the other surface of the fixing block 441 away from the support block 42 for smoothly resisting the switch 30. When assembling, position 杈641, 642 knife another! The over-clamping hole Mg, 414, the brace block 42 is inserted into the accommodating cavity 621 to abut against the bearing portion 531, the supporting bevel 421 abuts against the reflecting surface 523, and the fixing portion 41 respectively abuts the fixing portion 61 and the second light guiding portion 52. The positioning posts 641 and 642 are respectively assembled with the light guides 50 and the light guides 50 on the base 40 by means of a heat fusion connection with the positioning holes 413 and 414, respectively. In the present embodiment, in order to reduce the contact surface of the base 40 in contact with the light guiding member 50, the light beam transmitted from the light guiding member 5 is lowered. The base 4 is made of a light color material to enhance the reflection f\ effect. Referring to FIG. 5, a housing 70 is covered around the indicating switch 1A. A corner of the housing 70 is provided with a button hole 71. The housing 70 is mounted on an electronic device (not shown). The pressing portion 62 and the third light guiding portion 53 pass through the button hole 71 and are slidably disposed in the button hole 71 to closely match the button hole 71. [0011] When pressed, the pressing portion 62 of the button 60 is pressed, so that the bearing portion 531 of the light guiding member 50 presses against the supporting block 42 of the base 40, the contact 43 presses the switch 30, and the opening and closing 30 conducts the electronic device. In the working state, the illuminating member 20 emits light to indicate the working state of the electronic device.
