In this embodiment, the button 3 is made of a material having an anti-glare effect, and is integrally formed by injection molding, and the anti-glare material is preferably a light diffusion material. The light diffusion material is made by PC, light diffusion powder, microelement mixture, has the effect of soft light for button 3 made by the light diffusion material is in the use, and the light that light source subassembly 2 sent can not cause dazzling after seeing through button 3 to the user, improves user's experience and feels. Through integrative injection moulding, can improve the production efficiency of button 3 to reduce button 3's manufacturing cost.

EXAMPLE III

As shown in fig. 1, the button 3 includes: a light-shielding region covered with a light-shielding layer; and a light-transmitting area forming the prompt pattern.

In this embodiment, the button 3 includes a light-shielding region and a light-transmitting region, and the light-shielding region is covered with a light-shielding layer for blocking light from passing through; the shape of the light-transmitting area is the shape of the prompting pattern, and when the light emitted by the light-emitting source component 2 penetrates through the light-transmitting area, the prompting pattern can be formed. There are various methods for processing the prompt pattern of the button 3, and the method one: firstly, coating a shading layer on the surface of the button 3, then engraving by laser, removing the shading layer according to the shape of the prompt pattern to form a light-transmitting area in the shape of the prompt pattern, and forming a luminous prompt pattern on the surface of the button 3 when light passes through the light-transmitting area; the second method comprises the following steps: firstly, a model pattern which is the same as the prompt pattern is placed in the prompt pattern area on the surface of the button 3, then the surface of the button 3 is coated with a light shielding layer, and after the light shielding layer is coated, the model pattern is removed, and a light transmitting area of the prompt pattern is formed on the surface of the button 3.
