ELECTROSTATIC CAPACITY TYPE SWITCH

To provide an electrostatic capacity type switch having high-speed responsiveness and enabling stable two-stage input by one stroke.SOLUTION: An electrostatic capacity type switch comprises: a fixed electrode 17 including a first electrode 171 and a second electrode 172 arranged so as to be insulated from the first electrode 171; and a movable electrode 16 formed using a metal plate made of stainless steel or the like. The electrostatic capacity type switch further comprises a rubber member 11 that incudes a protrusion part and changes a distance between the movable electrode 16 and the fixed electrode 17 by displacing the protrusion part. The movable electrode 16 includes a first region P1 and a second region P2. The protrusion part has: a center protrusion part 113 that is displaced by a first pressing force, which is applied to the rubber member 11, to thereby set the first region P1 close to the fixed electrode 17; and a peripheral protrusion part 114 that is displaced by a second pressing force stronger than the first pressing force to thereby set the second region P2 close to the fixed electrode 17.SELECTED DRAWING: Figure 1 【課題】高速応答性を有し且つ１ストロークで安定した二段入力が可能な静電容量式スイッチを提供する。【解決手段】第１の電極１７１、及び第１の電極１７１とは絶縁して配置された第２の電極１７２からなる固定電極１７と、ステンレスなどの金属板で形成された可動電極１６とを有する。更に、突起部を備え、該突起部を変位させることにより可動電極１６と固定電極１７との間の距離を変化させるラバー部材１１を有する。可動電極１６は、第１の領域Ｐ１と第２の領域Ｐ２を備え、突起部は、ラバー部材１１の第１の押圧により変位して、第１の領域Ｐ１を固定電極１７に接近させる中央突起部１１３と、第１の押圧よりも大きい第２の押圧により変位して、第２の領域Ｐ２を固定電極１７に接近させる周囲突起部１１４を備える。【選択図】 図１
