Abstract (en)
[origin: EP2565888A1] PROBLEMS In a contact member provided with a plurality of protrusions in a curved portion and a switch device using the contact member, deterioration of an operating sensation is caused not to occur even though a pressing point is deviated from the center. SOLVING MEANS A dome-shaped curved portion 12 is formed in a contact member 10 formed of a metal leaf spring material, and three protrusions 13a, 13b, and 13c protrude toward a substrate at the periphery of a center O1. The extension direction of the leaf spring material that forms the contact member 10 is the X direction. The protrusions 13b and 13c are disposed at positions where the circular contours thereof do not overlap with a vertical center line Ox extending in the extension direction. Therefore, the positions of the protrusions may be displaced with respect to a direction in which an operating sensation is deteriorated due to the influence of the extension direction of the material, so that when a position distant from the center 01 is pressed, an area where the operating sensation is not deteriorated may be enlarged in a wide range in the X direction and the Y direction.
