Abstract
A simple-structured, highly dustproof movable contact unit having positive tactile response, and a panel switch using the same, and each manufacturing method. The movable contact unit contains movable contact (3), base film (11), and separator (4). The movable contact, which is made of a conductive metallic sheet having resiliency, is formed into a bottom-open dome-like shape. The base film holds the movable contact through adhesive layer (12) formed under the film. The base film has projections (13) corresponding to each movable contact, which are formed into a shape conforming to the dome-like movable contact. The upper surface of the separator, which has been subjected to a release treatment, is affixed with the adhesive layer beneath the base film. The root portion of the each projection conforming to the shape of the movable contact is tightly affixed to the separator through the adhesive layer under the base film.
