More Information
Summary:A push switch 1 includes a movable contact member 20 with a bulging portion 20a. The push switch 1 has a fixed contact member 10 with a first fixed contact portion 10a and a second fixed contact portion 10b. The push switch 1 includes an electrically conductive vibration damping member 25 elastically deformable by an operating force lower than load for inversion operation of the bulging portion 20a. 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 increases 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.
