Abstract
A small movable contact unit and a panel switch which prevent peeling from an edge even though the width between the edge of a base sheet and a movable contact is narrowed. The movable contact unit includes the movable contact and base sheet. The movable contact has a round dome shape and is made of a resilient metal sheet. The base sheet is an insulating film which adheres a dome tip of the movable contact with an adhesive applied to its undersurface for holding the movable contact at a predetermined position. A supplementary adhesive is applied to a ring non-adhesive area of the movable contact disposed near the edge of the base sheet at a portion toward the edge of the base sheet. Accordingly, the movable contact disposed near the edge is adhered to and held by the base sheet using the adhesive including the supplementary adhesive.
