Abstract

A switch including a waterproof and light leak prevention structure is disclosed. The switch according to an embodiment of the present invention is a switch including a light emitting member and a push switch on a mount, and includes a switch including a cover plate provided on the mount and configured to cover the light emitting member and the push switch, and the cover plate comprises includes a rubber dome disposed at a position corresponding to the push switch, a light emitting member cover configured to cover the light emitting member at a predetermined distance from an upper surface of the light emitting member, and a light leak prevention protrusion configured to surround a periphery of the light emitting member and to extend upward up to a predetermined height.

First claim

What is claimed is:

1. A switch including a light emitting member and a push switch on a mount, comprising: a cover plate provided on the mount and configured to cover the light emitting member and the push switch, wherein the cover plate comprises: a rubber dome disposed at a position corresponding to the push switch; a light emitting member cover configured to cover the light emitting member at a predetermined distance from an upper surface of the light emitting member; and a light leak prevention protrusion configured to surround a periphery of the light emitting member and to extend upward up to a predetermined height, the light leak prevention protrusion and the rubber dome being formed into a single piece made of a same material, the light leak prevention protrusion having a height substantially the same as the rubber dome; wherein the light emitting member cover is joined together with an inside of the light leak prevention protrusion.

2. The switch as claimed in claim 1 , wherein the cover plate is made of a flexible material having a predetermined elastic restoring force.

3. The switch as claimed in claim 2 , wherein a material of the cover plate is made of rubber.

4. The switch as claimed in claim 1 , wherein the rubber dome, the light emitting cover and the light leak prevention protrusion are integrated together.

5. The switch as claimed in claim 1 ,
wherein the rubber dome comprises:
a pressing contact portion configured to be displaced downward by receiving a push operation of a user and having a predetermined area in a plan view;
a support portion extending by a predetermined height from an upper surface of the cover plate and is joined with an outer peripheral surface of the pressing contact portion; and
a pressing projection portion projecting by a predetermined length from a lower surface of the pressing contact portion, and configured to push the push switch along with the downward displacement of the pressing contact portion, thereby implementing a switching operation.

6. The switch as claimed in claim 5 , wherein the pressing contact portion and the support portion are joined together, and a sealed space is formed inside the rubber dome.

7. The switch as claimed in claim 1 , wherein the light emitting member cover is made of a transparent material.

8. The switch as claimed in claim 1 , wherein the light leak prevention protrusion is formed at a height corresponding to a height of the rubber dome protruding upward.

9. The switch as claimed in claim 1 , further comprising:
a bent portion configured to surround at least part of both ends of the mount and formed at both ends of the cover plate.
