Claims

[Scope of utility model registration request]

a dome-shaped movable contact whose top part flips over when pushed in a predetermined stroke; an outer fixed contact that is always in contact with the annular base of the dome-shaped movable contact; and a dome-shaped movable contact that is located inside the outer fixed contact. an inner fixed contact facing the top of the base, and a base on which the dome-shaped movable contact is mounted, with the outer fixed contact and the inner fixed contact formed on one side;
In a device in which both fixed contacts are electrically connected by inverting the top of the dome-shaped movable contact and bringing it into contact with the inner fixed contact, an upright portion is provided on the base for regulating the position of the base of the dome-shaped movable contact. A switch structure characterized in that the base is provided with a recess facing a part of the base, and a lead line of the inner fixed contact is formed along the surface of the recess.
