Push button capable of prompting pressing state and its preparation method

The present invention relates to a push switch, and more particularly to a push switch capable of prompting a pressed state and a method of manufacturing the same.

According to the switch, the specifications and size of the switch are very wide, and the application range is quite wide. The electronic switches commonly used in general precision equipment, small equipment or small appliances are mostly called smart switches, micro switches or tact switches. Since such switches are relatively short and light in size, they can be used in electronic devices or instruments where space is limited or only small or micro switches can be provided, such as industrial applications such as 3C electronic products or microcomputers.

The traditional push switch is mainly composed of a base and a movable button, and the action mode is a push button, so that the positive and negative electrodes inside the base are in contact with each other to be turned on, and the power is turned on and off, however, due to the foregoing The light touch relationship refers to the micro switch, which has a small volume and the pressing movement of the button is not long, so that the user is not easy to know whether the switch is actually pressed. For example, one of the more frequently occurring conditions is that the switch is mistaken. It has been pressed, but in fact it is not the same, the function that the switch wants to start or execute cannot be completed; the other situation is that the switch has actually been pressed, but it is considered that there is no pressing success, and immediately press it again, so that the original The function being executed is turned off or re-executed, and the instantaneous current caused by continuous pressing of the switch easily damages the switch, even the application product. Therefore, in order to let the outside world know the pressing state of the switch, the pressing-opening relationship is improved, and the internal position feedback structure or the light-emitting module is provided inside, and once the switch is pressed, the internal light-emitting module emits light and transmits through the permeable light. The button is displayed outside to indicate that the switch has been pressed. However, the conventional switch with internal illumination function has a light-transmissive button, but it is manufactured by injection molding together with injection molding technology. In other words, if the light is not well formed after the button is formed, That is, the change cannot be corrected, it is necessary to reproduce, and the manufacturing cost is quite expensive, and the gloss and wear resistance of the button surface are limited by the raw materials and technology of injection molding.

SUMMARY OF THE INVENTION An object of the present invention is to provide a push switch capable of indicating a pressed state by internal light emission and having a wear-resistant and gloss-increasing cap, and a method of manufacturing the same.

Another object of the present invention is to provide a push switch that ensures a straight up and down movement after the switch is pressed, thereby actually turning the switch on.

In order to achieve the foregoing objective, the present invention may provide a push switch in a pressed state, comprising: a cap that is transparent to light and includes a surface layer, the surface layer is sequentially sprayed with a first UV ink layer and a half transparent chrome layer. And a second UV ink layer; a pedestal having an accommodating space therein, and one end of the accommodating space forms an opening. A connecting seat is sleeved on the bottom of the cap, and the connecting seat is permeable to light and completely covers the opening of the receiving space. A movable seat includes a body, a connecting end disposed at one end of the body, and a limiting portion disposed at the other end of the body, the limiting portion extending laterally out of the body and located at the body In the space, the connecting end is connected to the connecting seat, and the movable seat can be displaced by the pressing of the cap.

In a specific implementation, the fixing walls 82 can be embedded in the corresponding wall surfaces of the base 4 by the embedded card structure.

Referring to the fifth figure, when the push switch 1 of the present invention is not pressed, the limiting portion 33 of the movable seat 3 abuts against the bottom edge of the frame portion 81 by the pushing of the elastic member 6, so as to limit the longitudinal displacement of the movable seat 3. The purpose. As shown in the sixth figure, after the cap 2 is pressed, and the contact terminal group 71 of the circuit unit 7 electrically contacts the signal terminal group 72, the push switch 1 is turned on, and the light emitted from the light-emitting element 51 is directly transmitted through the cap 2 Display, so that the outside can easily recognize the pressing state of the switch. In addition, since the guide groove 331 is flush with the outer surface of the body 31 (as shown in the fourth figure), the body 31 can smoothly enter and exit the accommodating space 40 when the movable seat 3 is displaced. In another implementation, an image layer 25 (shown in Figures 5 and 6) may be additionally disposed between the cap 2 and the connector 24, and an image or text, or image and image may be printed thereon. The combination of characters, the image layer 25 may be a single separate light transmissive film, or directly formed on the top surface of the connecting seat 24 by lightning or printing, whereby the cap 2 transmits the inner light emitting element 51. The illumination can display an image or text of the image layer 25 (as shown in the first figure) to assist in explaining the switch pressing state or the function corresponding to the switch; when the light emitting element 51 does not emit light, the image layer 25 cannot be The outside is displayed through the cap 2.

Please refer to the seventh figure for a block diagram of a method for manufacturing a push switch capable of prompting a pressing state, comprising the step S1: providing a light transmissive cap 2; and step S2: using a medicament to the surface layer 20 of the cap 2 For wiping cleaning, the agent may be white electric oil, that is, a component containing n-hexane; step S3: performing a dry dust removal step to make the surface layer 20 of the cap 2 dry and dust-free; step S4: spraying the first UV ink layer 21 in the surface layer 20 of the cap 2 and curing the first UV ink layer 21; Step S5: vacuum plating the semi-transparent chrome plating layer 22 on the surface of the cured first UV ink layer 21; Step S6: spraying The second UV ink layer 23 is on the translucent chrome layer 22, and the second UV ink layer 23 is cured; Step S7: providing a light transmissive connection seat 24, which is sleeved on the bottom of the cap 2; Step S8: providing a The inside is a hollow movable seat 3, one end of which is connected to the connecting seat 24 to connect the cap 2 to the movable seat 3; and step S9: a base 4 is provided, and a receiving space 40 is formed therein, and the receiving space is formed therein. An opening 401 is formed at one end of the 40, and a light emitting module 5 is disposed in the accommodating space 40. At least one elastic member 6, and a circuit unit 7, the movable holder 3 by the opening line 401 into the accommodating space 40, and slidably connected to the base 4, base 24 may be connected to the opening 401 in the cover.
