徴とするメンブレンスイツチ。 An upper switch sheet and a lower switch sheet, each comprising a movable contact and a fixed contact constituting a contact portion, respectively formed on opposing parts of a flexible wiring sheet, are laminated with a spacer sheet holding the two contacts at a predetermined distance. In the membrane switch, the contact portion is made conductive by pressing down the upper switch sheet to send a contact signal, and the movable contact is configured to provide a click feeling when the movable contact is pushed onto the upper switch sheet. What is claimed is: 1. A membrane switch comprising: an operation sheet having a dome-shaped bulge formed thereon; and a ring-shaped stepped portion formed in the middle of the dome-shaped bulge of the operation sheet.
