Description

  The present invention relates to a push button, and more particularly to a push button capable of displaying a pressing state and a manufacturing method thereof.

  A conventional push button mainly includes a base and a movable button. When the button is squeezed, the yin and yang electrodes inside the base are brought into contact with each other and become conductive, thereby turning on the power. Off operation is achieved.

However, in the above-described conventional push button, the one that is turned on and off by being touched lightly is a micro switch, its volume is small, and the moving stroke by pressing the button is not long, so that the button is surely pressed. It is difficult for the user to perceive whether or not the button is damaged by the inrush current, and the final product may be damaged.
For this reason, in order to be able to confirm the pressing state of the button from the outside, the push button has been improved, and a stepped feedback structure or a light emitting module has been installed inside. Once the button is pressed, the internal light emitting module emits light, and the translucent button is transmitted and displayed outside to indicate that the button has been pressed reliably.
However, a conventional button having an internal light emitting function has a light-transmitting button, but the manufacturing method is such that a pigment is injected together by an injection molding technique. In other words, if the translucency is insufficient after the button is molded, it cannot be corrected or changed, and it must be manufactured again, so that the manufacturing cost is too high. Also, the gloss and wear resistance of the button surface is limited by the raw material and technology being injection molded.

  Therefore, the present inventor considered that the above-mentioned drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at a proposal of the present invention that effectively improves the above-described problems by rational design.
