Abstract
A multi-directional operating switch comprises: a case made of resin having generally a square opening on top, provided on a bottom surface thereof with a central contact, an outer contact, and peripheral contacts disposed at each corner of the opening; a dome-like circular movable contact disposed within the opening in a manner to rest in contact with the outer contact; a manipulation body having a flange and a contact plate under the flange, placed above the dome-like circular movable contact; and a cover for covering the opening and having a shaft of the manipulation body penetrating therethrough. Switching operation is made between the central contact and the outer contact when the shaft is depressed, and between any adjacent pair of the peripheral contacts, as the dome-like circular movable contact is being deformed, when the shaft is tilted.
