Summary:The push switch 1 includes a movable contact member 20 comprising a metal plate and having a bulging portion 20a that is operably invertible. The push switch 1 has a fixed contact member 10 provided with: a first fixed contact portion 10a capable of being in contact with and separated from the movable contact member 20; and a second fixed contact portion 10b provided on an outer edge portion of an internal bottom surface 51a. The push switch 1 is further provided with a vibration damping member 25 which is electrically conductive and elastically deformable by an operating force lower than the load for the inversion operation of the bulging portion 20a. The bulging portion 20a and the second fixed contact portion 10b are electrically connected through the vibration damping member 25. When the movable contact member 20 is operated from the initial state, the vibration damping member 25 is deflected due to elastic deformation while the operating force during the elastic deformation of the vibration damping member 25 changes so as to increase monotonically. When the movable contact member 20 returns from the bulging portion 20a being in an inverted state to the initial state, the vibration damping member 25 absorbs the vibrations from the movable contact member 20.
