摘要： 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 through hole is an independent through hole being not electrically connected to a circuit of the substrate.

摘要： A switch device includes a substrate having at least one fixed contact and an inflow/outflow section provided with at least one through-hole, and a rubber contact to cover the substrate. The rubber contact includes at least one moving section disposed facing the respective at least one fixed contact, the moving section elastically deforming such that moving contacts corresponding to the respective fixed contacts are capable of contacting/separating, an in/out section disposed facing the inflow/outflow section and configured to form a space with the inflow/outflow section, a flow path section configured to form a flow path to connect the in/out section and the at least one moving section, and at least one chamber section having a space larger than a space occupying along representative length of the flow path section on a portion of the flow path section, and having strength such that a shape of the space is maintained.
