ボタンスイツチ。 A switch case having a plurality of fixed contact pieces fixed to the bottom wall side, a conductive dome-shaped reversing spring disposed inside the switch case opposite to the fixed contact pieces, and the dome-shaped reversing spring It is equipped with one pair of two sets of support legs that are coupled to the reversal spring along the outer periphery and support the reversal spring in a tensioned state, and the first stage movement is achieved by the deformation of the support legs when subjected to a pushing operation. A push button switch characterized in that it is configured so that a second stage operation feeling is obtained by the reversal deformation of a dome-shaped reversing spring.
