To improve stability regarding an operational feeling.SOLUTION: A push switch 1 comprises a case 2, a fixed contact member 3, a movable contact member 4, a first pressing member 5, and a second pressing member 6. The movable contact member 4 is disposed in a recess 23 of the case 2 and has a movable contact 40 which is brought into contact with a fixed contact 30 of the fixed contact member 3 by a pressing operation. The first pressing member 5 has one surface 50 which is a surface on a side to be pressed by the pressing operation. The second pressing member 6 is disposed between the first pressing member 5 and the movable contact member 4, and has a facing surface 60 which faces the movable contact member 4. The second pressing member 6 applies pressing force received from the one surface 50 side to the movable contact member 4 via the facing surface 60. The one surface 50 is larger than the facing surface 60.SELECTED DRAWING: Figure 5 【課題】操作感に関する安定性の向上を図ること。【解決手段】プッシュスイッチ１は、ケース２と、固定接点部材３と、可動接点部材４と、第１押圧部材５と、第２押圧部材６と、を備える。可動接点部材４は、ケース２の凹部２３に配置され、押圧操作により固定接点部材３の固定接点３０に接触する可動接点４０を有する。第１押圧部材５は、押圧操作による押圧を受ける側の面である一面５０を有する。第２押圧部材６は、第１押圧部材５と可動接点部材４との間に配置されて、可動接点部材４と対向する対向面６０を有する。第２押圧部材６は、一面５０の側から受けた押圧を、対向面６０を通じて可動接点部材４に与える。一面５０は、対向面６０よりも面積が大きい。【選択図】図５
