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.
