Abstract: A movable contact point according to the present invention includes a dome-shaped portion protruded upwardly at its center portion and at least three protrusions formed, on the dome-shaped portion, to protrude downwardly at positions which are evenly spaced apart from the center position of the dome-shaped portion, wherein the protrusions are formed to have a quadrangular-pyramid shape protruding downwardly and having a spherical-shaped apex portion.

Abstract: A movable contact unit includes a first movable contact stuck on an adhesive layer beneath a lower face of an insulating film, and a second movable contact placed on the insulating film such that it is overlaid on the first movable contact via the insulating film in between. The movable contact unit has greater repulsive force and is excellent in durability.

Abstract: A movable contact is made of a resilient and electrically conductive thin metal plate so that a depressing operation onto the top thereof allows turning over of the central section thereof. The movable contact is shaped like a dome bowing upward and open downward, and includes at least three projections radially placed at the center where the turn-over occurs. A top view of the projection shows a long and narrow shape extending in the radial direction. The downward protruding amount of the respective projections increases along the radial direction from the center to the outer side, and the respective projections each have a flat face having a given width along the circumferential direction. When the movable contact is in operation, the movable contact touches the object at an outer section of the flat face and along the circumferential direction.

Abstract: Provided are a movable contact element used in a panel switch on the operation panel of various electronic devices and a panel switch using the movable contact element, which provide excellent operation feeling and simplify the production and integration processes. Between base sheet and the center of the outer surface of domed part of movable contact point is disposed spacer piece. Base sheet has a small protrusion swollen upward on its top surface, and the small protrusion serves as pressed part. This structure can eliminate the detachment of spacer piece from base sheet, and can also both simplify and improve reliability of the production and integration processes of the movable contact element and the panel switch. Providing pressed part ensures that the center of movable contact point is fully pressed down to a predetermined level, thus providing the user with excellent operation feeling.

Abstract: An insulating film 3 is provided with an opening 4 whose size is substantially equivalent to or slightly smaller than the outer configuration of electronic component 5. A conductive pattern 2 is formed on insulating substrate 1. After forcibly inserting the main body of electronic component 5 into said opening 4, terminals 6 are put between insulating film 3 and insulating substrate 1 and disposed in such a manner that terminals 6 are brought into contact with conductive pattern 2. Then, insulating film 3 is connected with insulating substrate 1 by fusing them in a region surrounding terminals 6, thereby firmly fixing terminals 6 of electronic component 5 on conductive pattern 2.
