Compared with the prior art, the protrusion is provided on the protrusion. The embodiment of the present invention can be applied to electronic devices such as mobile phones, personal digital assistants, and notebook computers. Please refer to the key assembly 10 of the preferred embodiment of the present invention shown in FIGS. 2 and 3. The button assembly 1A includes a plurality of keycaps η, a plurality of pressing bodies 13, a light shielding sheet 15, a light guide plate 17, a casing 18, and a circuit board 19. The pressing body 13 is abutted against the circuit board 19, and the other end is fixed to the keycap 11 through the light guide plate 17. The light shielding sheet 15 is located between the light guide plate 17 and the keycap 11 for shielding light. The pressing body 13 is divided into a single pressing body 131 and a composite pressing body 132. Each of the single pressing bodies 131 includes a pressing portion 1311 and a fixing portion 1312 opposed to the pressing portion 1311. Each of the composite pressing bodies 132 includes a plurality of pressing portions 1321 and a plurality of fixing portions 1322 opposed to the pressing portions 1321. The pressing portion 1311 is protruded from the fixing portion 1312 on both sides of the single pressing body 131. The pressing portion 1321 protrudes from the fixing portion 1322 on one side of the composite pressing body 132. The pressing body 13 defines a plurality of protrusions 133 around the fixing portions 1312 and 1322. The protrusions 133 are used to support the light shielding sheet 15 so that the light shielding sheet 15 shields the keycap 11 from the housing 18. The gap is assembled to prevent light from being transmitted through the pressing gap of the pressing body 13 from the mounting gap between the keycap 11 and the housing 18 to cause light leakage. The visor 15 is made of a resilient and non-light permeable material that provides a resilient return to the return of the cap H. The light shielding sheet 15 is provided with a plurality of through holes 151 corresponding to the pressing body 13, that is, the single pressing body 131 and the composite pressing body 132. The pressing body 13 passes through the through hole 151 and the key cap. 11 contact. The light guide plate 17 is provided with a plurality of through holes 171' corresponding to the pressing body 13 through the through hole 171, and is in close contact with the hole wall of the through hole 171. The pressing body 13 can be fixed to the light guide plate 17 by double-shot molding. The light guide plate π is for guiding light to the keycap 11 to illuminate the keycap 11. A plurality of button holes 181 corresponding to the key cap 1:1 are disposed through the housing 18 for receiving the key cap 1:1. The circuit board 19 is provided with a plurality of trigger sensing sheets 191 and a plurality of illuminants 192. The trigger sensing piece 191 corresponds to the pressing portions 1311 and 1321. In the present embodiment, the illuminant 192 is a light emitting diode for providing a light source for the button assembly 10. When the button assembly 10 is assembled, the fixing body 1311 1321 of the pressing body 13 is first passed through the through hole 171 of the light guide plate 17, and the fixing portion 1311, 1321 and the pressing portion 1311 are 6 M377686. And 1321 are respectively located on both sides of the light guide plate 17; then, the light shielding sheet 15 is placed on the pressing body 13, and the protruding column 133 is supported by the light shielding sheet 15 and the fixing portions 13Π, 1321 are passed through. The through hole 151; then the key cap workers are respectively placed on the fixing portions 1312, 1322; finally, the housing 18 is closed and the key cap is passed through the button hole 181. The keycap u- is in close proximity to the light shielding sheet 15, that is, the group of the button assembly 1 is completed. The light shielding sheet 15 is located between the light guide plate 17 and the keycap 11, and the light shielding sheet 15 is supported by the protruding post 133 to effectively prevent light from leaking through the keyhole 181. When the button assembly 10 is used, when a certain keycap U is pressed, the light shielding sheet 15 can be deformed together with the keycap n, and accumulates - elastic force, and the pressing body 13 is also depressed, so that the pressing The portion 1312 or 1321 triggers the trigger sensing sheet 191 such that the trigger sensing sheet 191 is electrically conductively connected to the circuit board 19; when the keycap 11 is released, the shutter 15 returns to the original position, and the keycap n is reset, so that the triggering The sensing sheet 191 is electrically separated from the circuit board 19. Compared with the & technology, the button assembly of the present invention is provided with a stud 133 on the pressing body 13, and the stud 133 supports the visor 15 to shield the keycap n and the button A gap is formed between the holes 181, thereby preventing light leakage, and the spring connecting the pressing body 13 and the triggering sensing piece 191 is omitted, thereby simplifying the entire button assembly.
