Latest Patents

Shinagawa holds a patent for a "Dome sheet unit and membrane switch having the same." This invention addresses the challenge of securely attaching an elastically deformable dome to a board. The design ensures that the dome remains attached even when the fixing sheet is thinner and smaller, thus maintaining a smaller footprint. The membrane switch features a dome that projects toward the surface and is dented toward the back surface through elastic deformation. A flexible fixing sheet with an adhesive face secures the dome in place, utilizing a stretching part that extends radially outward from the dome's outer rim. Additionally, slits in the fixing sheet prevent the stretching part from joining with the dome covering part, ensuring optimal functionality.
