Abstract: A light illuminating type switch with a good click rate and having a desired click characteristic near to that of a single member of a metal dome. Fixed contacts 7a are provided on a base sheet 7. On an upper side of the base sheet 7, a dome shaped movable contact 8 capable of electrically connecting the fixed contacts 7a on the base sheet by being elastically deformed is arranged. The surface of the dome shaped movable contact 8 is attached with a flexible EL sheet E by using adhering agents 9a and 9b via an insulating member 6 over a peripheral portion of the dome shaped movable contact 8. The EL sheet E is formed with cut portions 10 partially at positions along an outer peripheral edge of the dome shaped movable contact 8. At least a pair of the cut portions 10 are formed at symmetrical positions centering on the movable contact 8.
