Abstract
A push switchincludes a movable contact memberwith a bulging portion. The push switchhas a fixed contact memberwith a first fixed contact portionand a second fixed contact portion. The push switchincludes an electrically conductive vibration damping memberelastically deformable by an operating force lower than load for inversion operation of the bulging portion. When the movable contact memberis operated from the initial state, the vibration damping memberis deflected due to elastic deformation while the operating force during the elastic deformation of the vibration damping memberincreases monotonically. When the movable contact memberreturns from the bulging portionbeing in an inverted state to the initial state, the vibration damping memberabsorbs the vibrations from the movable contact member
