As shown in fig. 2 to 9, the present invention provides a push button switch with a light-transmitting effect, comprising: a base 100; a light emitting assembly 200 mounted on the base 100, wherein the light emitting assembly 200 includes a plurality of light emitting sources 210; a pressing plate 300, which is located above the light emitting assembly 200 and detachably connected to the base 100, wherein a light blocking part 310 is disposed on the pressing plate 300 and corresponds to the positions of the plurality of light emitting sources 210; the button 400 is located above the pressing plate 300 and detachably connected to the base 100, wherein the button 400 includes a cover 410, and an opaque film 420 covering the surface of the cover 410 and integrally disposed with the cover 410, and a transparent region corresponding to the position of the light source 210 is disposed on the opaque film 420.

In this embodiment, the opaque film 420 is made of a UV film, which can achieve the effect of blocking ultraviolet light and short wavelength visible light, wherein the transparent area is a pattern or a character, if the button switch is applied to a doorway of a hotel, a hotel or a room, characters on the opaque film can be written with characters such as "do not disturb", "please wait for a short time", "please clear up" and the like, and the characters are printed on the back of the film by a "silk screen printing" method, and the characters or the pattern are made of a transparent material, such that the opaque film 420 can be set in such a way that the area provided with the characters and the patterns can transmit light under the irradiation of the light source 210, and the area provided with the characters and the patterns can not transmit light to form the transparent area but the area without the characters and the patterns, so as to form the opaque area. In addition, the thin film printed with characters and patterns and the housing 410 are injection molded through a nano-imprint mold to form an integrated structure.

In this embodiment, according to the material that the film chooseed for use, make can effectually prevent greasy dirt or fingerprint at film surface shaping, and according to the material and the silk screen printing characters of film, the technology of pattern, make button switch under the on-state, its characters, the pattern region can the printing opacity, and not set up the characters, the pattern region can not realize the printing opacity, in addition, through the technology of moulding plastics, make film and housing 410 form the integral type structure, thereby button switch's assembly efficiency has been improved, and dustproof, waterproof effect, and the cost of button switch accessories management has been reduced.

According to the button switch with the light transmission effect, the light blocking part 310 is arranged on the pressing plate 300, so that the irradiation range of the light source 210 is limited, the phenomena of light channeling and light leakage are avoided, in addition, the integral structure arrangement of the film and the housing 410 is adopted, the light leakage phenomenon is avoided, the assembly efficiency is improved, the dustproof and waterproof functions are improved, and the management cost of the button switch spare and accessory parts is reduced.

In order to improve the appearance of the surface of the button switch, the surface of the film can be imprinted with micro-grains through the literary grinding tool, so that a high-gloss mirror surface effect is formed on the surface of the film.

In order to further improve the light transmittance, the thickness of the cover 410 corresponding to the light-transmitting region (the position where the text and the pattern are located) is reduced, i.e. the thickness of the cover 410 corresponding to the light-transmitting region is thinner than the thickness of the cover 410 corresponding to the light-blocking region, so that the light-emitting source 210 can be more effectively projected.

In order to further avoid the phenomena of light leakage and light channeling, an accommodating cavity 411 is formed in the housing 410, and the positions of the accommodating cavity 411 correspond to the position of the light emitting source 210 and the position of the light blocking portion 310, respectively, wherein the accommodating cavity 411 and the light blocking portion 310 form a closed space.
