The present invention relates to a push switch with LED light, and in particular, to a thin structure to make small size switches with LEDs.
On a variety of electronic products, it is often seen that control buttons are used to generate signals to activate and control functions. However, there are many specifications, sizes, and types of switches, and application ranges of the switches are quite wide.
On some precision equipment, due to limitations of available space, it will need to be applied to switches with light having a very small size. For example, an overall thickness is only about a few mm, or even a switch with LED light having a size smaller than 3 mm will be needed.
In the technical field of the switches with light having small size, because the design of each institution has been very streamlined and well-established for years, it is not easy for a designer to achieve further streamlining and thinning through any structural change. It can be seen that there is a technical bottleneck in the prior art.
In this type of extremely small switch with light, we know that it is installed on a housing of an LED light. In order to ensure that a thickness of a metal wire of a power line does not affect an overall thickness, the metal wire is buried in a plastic outer housing, so as to ensure that a thickness of the metal wire does not increase the overall thickness. Therefore, it can be seen that a size that an integrated thickness of the outer housing and the metal wire can reach is limit of the technology.
In addition, for the above technology, not only the thickness is limited, if users expect to use a plurality of LED light sources, it will be difficult to make because of increase of the metal wires. This is a main technical bottleneck in an application of technologies. Furthermore, in conventional switches, it is necessary to connect to the outside through transmission pins. This part is difficult to simplify, and it is also a problem that cannot easily reduce space requirements.
Therefore, in view of the foregoing, an inventor of the present invention contemplates and designs a push switch with LED light, in order to improve a lack of current technologies, thereby enhancing an industrial implementation.
In view of aforesaid shortcomings of the prior art, the present invention is to design a push switch with LED light with patent elements such as novelty, inventive step, and industrial applicability, in order to overcome difficulties of the prior art.
In order to achieve the above objective, technical means adopted in the present invention is to design a push switch with LED light. The push switch with LED light comprises a substrate provided with a plurality of conductive elements thereon, wherein the plurality of conductive elements exposes an upper surface of the substrate and are separated with each other at a non-conductive state, and wherein the substrate is a printed circuit board, and the conductive element is a printed circuit on a surface of the substrate; at least one LED lamp correspondingly disposed on an upper side of the substrate and is electrically connected to one of the conductive elements; a conductive elastic sheet disposed on the substrate, wherein the conductive elastic sheet is a sheet material with elasticity and arc shape, and wherein the conductive elastic sheet corresponds to the non-conductive components, and a bottom wall of the conductive elastic sheet comprises conductive characteristics; and a pressing upper cover correspondingly covered and fixed on the substrate, wherein a pressing portion is provided at a center of the pressing upper cover, a pressing block extending downward is provided below the pressing portion, the pressing portion can be moved downward under pressure so that the pressing block presses the conductive elastic sheet, when the conductive elastic sheet contacts the conductive elements, the conductive elastic sheet and the conductive elements are turned on to drive the at least one LED lamp to emit light.
Wherein, the at least one LED lamp is arranged in a horizontal direction, and a refractive plate is disposed in front of the at least one LED lamp, which is made of a material with light guiding characteristics.
Wherein, a thickness of the substrate ranges from 0.3 mm to 1 mm.
Wherein, a bottom of the substrate is provided with a welding portion.
Wherein, a height from an upper surface of the pressing portion to a bottom wall surface of the substrate ranges from 1.5 mm to 2 mm.
Wherein, a light transmitting portion is provided on the pressing portion.
The design of the push switch with LED light of the present invention is mainly through a subversive design, and further, the printed circuit board is used as a carrier for the LED lamp. By replacing the metal wires with the characteristics of extremely thin printed circuits, it is possible to create a very thin thickness in the use of space, thereby improving the conventional technology that it is impossible to place a plurality of LED lamps on a switch with light that is minimized to a thickness of 2 mm or less, for example. In addition, the bottom of the substrate is fixed and conductive through welding, which can save the space required by conventional technology to use pins for transmission, and can further achieve a purpose of thinning, which is beyond the reach of the current technology.
