Description

Take push switch of LED lamp

Technical Field

The invention relates to a push switch with an LED lamp; and more particularly, to a switch having a thinned structure to make a switch with an LED in a slim size.

Background

In various electronic products, it is often seen that the control button generates a signal to start and control functions, and the size and variety of the switch are very various, and the application range is quite wide.

In some sophisticated devices, due to the limited space available, it may be desirable to apply the switch with light to very small dimensions, such as a thickness of only a few mm or so, or even less than 3mm in size.

In the field of this type of small switch with light, since the design of each mechanism is very simple and easy for years, how to achieve further simplification and thinning by any structural change is not easy, and there is a technical bottleneck in the prior art.

In this type of tiny light-carrying switch, we can know that the thickness of the metal wire of the power circuit does not affect the overall thickness of the switch, and the metal wire is embedded in the plastic casing, so that the thickness of the wire does not increase the overall thickness, and it is seen that the size of the integrated thickness of the casing and the metal wire is the limit of the technology.

Furthermore, for the above-mentioned technologies, not only the thickness is limited, but if the user desires to use a plurality of LED light sources, the manufacturing process is difficult due to the increase of the metal wires, which is a major technical bottleneck in the technical application; furthermore, in the conventional switch, the Pin pins need to be transmitted to make external connection, which is difficult to simplify and reduce the space requirement.

In view of the foregoing, the inventor of the present invention has devised and designed a push switch with LED lamp to overcome the shortcomings of the prior art and to enhance industrial application.
