Abstract

A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

First claim

What is claimed is:

1. A switch structure, comprising:
a light-emitting part configured to receive power from a vehicle and to radiate light;
a moving block located so as to surround the light-emitting part; and
a knob formed in an opening of the moving block, wherein the knob includes:
a light-transmissive part configured to allow light radiated from the light-emitting part to pass through the opening in the moving block; and
a film-printing layer located on a top surface of the light-transmissive part, the film-printing layer comprising a symbol;

wherein a top surface of the moving block is tapered in a height direction of the moving block and wherein the light-transmissive part is configured to surround the upper end of the moving block having a tapered shape;
wherein the side surface of the moving block adjacent to the top surface of the moving block is formed to protrude further than a respective side surface of the knob so as to form a stepped portion between the side surface of the moving block and the side surface of the knob;
wherein each of opposite ends on the film-printing layer is located inwards from an end of the moving block by 0.1 to 0.3 microns.

2. The switch structure of claim 1 , wherein the film-printing layer is formed to have a thickness ranging from 20 to 50 microns.

3. The switch structure of claim 1 , wherein the film-printing layer is configured to form a symbol at a position corresponding to the opening in the moving block such that light radiated from the light-emitting part passes therethrough.
