发明名称 Multi-directional operating switch and multi-directional operating device using the same
摘要 A multi-directional operating switch includes: a case made of resin having a generally square opening on top, provided on a bottom surface thereof with a central stationary contact, an outer stationary contact and peripheral stationary contacts disposed at each corner of the opening; a dome-like circular movable contact disposed in a manner to stay in contact with the outer stationary contact; a manipulation body having a flange, an upper surface and a lower surface of which are electrically conductive, 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 stationary contact and the outer stationary contact when the shaft is depressed, and between any adjacent two of the peripheral stationary contact and the electrically conductive cover, covering the opening of the case, when the same shaft is tilted.
