Abstract
A switch device includes a substrate provided with at least one first contact and including at least one through hole, and a contact rubber, being an elastic sheet covering the substrate, provided with a dome-shaped cavity configured to make a second contact portion including a second contact corresponding to the first contact elastically deformable to be capable of contacting to and separating from the first contact, a vent cavity portion provided corresponding to the through hole, and an air groove communicating with the cavity and the vent cavity portion between the substrate and the elastic sheet. The air groove includes a non-linear path.

A switch device, comprising:
- a substrate provided with at least one first contact and including at least one through hole;
- and
- a contact rubber, being an elastic sheet covering the substrate, provided with a dome-shaped cavity configured to make a second contact portion including a second contact corresponding to the first contact elastically deformable to be capable of contacting to and separating from the first contact, a vent cavity portion provided corresponding to the through hole, and an air groove communicating with the cavity and the vent cavity portion between the substrate and the elastic sheet,
- wherein the air groove comprises a non-linear path,
- wherein the vent cavity portion the cavity are on a same side of the substrate, and
- wherein the through hole pierces the substrate so as to allow air to flow therethrough, and wherein the cavity portion is larger than the air groove in a thickness direction of the switch device.
