摘要： A switch case includes a first metal plate, a dome shape metal plate, and a second metal plate. The first metal plate includes a first ring in which a plurality of first recesses are arranged along the first ring shape, and a second ring in which a plurality of second recesses are arranged along the second ring shape. The second metal plate includes a third ring in which a plurality of third recesses are arranged along the third ring shape, and a fourth ring in which a plurality of fourth recesses are arranged along the fourth ring shape. A direction along a line passing through a center of the first ring and a center of the second ring is different from a direction along a line passing through a center of the third ring and a center of the fourth ring.

摘要： A switch case includes a metal plate having a first surface and a second surface that is at a side opposite to the first surface, and a resin case embedding a part of the metal plate. The resin case includes a housing portion having an opening disposed on a surface of the resin case. The metal plate includes a terminal portion, a contact portion, and an intermediate portion positioned between the terminal portion and the contact portion. The terminal portion is exposed from the surface of the resin case, and the intermediate portion is embedded in the resin case. The intermediate portion is provided with first and second through-hole each penetrating the first surface and the second surface. A hole diameter of the first through-hole at the second surface is larger than a hole diameter of the first through-hole at the first surface.

摘要： The switch case includes a metal plate having a first surface and a second surface that is at a side opposite to the first surface, and a resin case embedding a part of the metal plate. The resin case includes a housing portion having an opening formed on a surface of the resin case. The metal plate includes a terminal portion, a contact portion, and an intermediate portion positioned between the terminal portion and the contact portion. The terminal portion is exposed from the surface of the resin case, and the intermediate portion is embedded in the resin case. The intermediate portion is provided with at least one through-hole penetrating the first surface and the second surface. The contact portion includes a part of the first surface exposed to the housing portion of the resin case. In the at least one through-hole, the hole diameter of the at least one through-hole at the second surface is larger than the hole diameter of the at least one through-hole at the first surface.
