。 A stem is attached to the main body case so as to be movable in and out of an opening provided in the main body case, and by operating a switch to move the stem in and out,
A switch element arranged in the main body case is turned on and off, and the switch element includes a frame body to which a fixed contact piece and a movable contact piece that comes into contact with and separates from the fixed contact piece are displaceably attached, and this movable contact piece. A spacer interposed between the contact piece and the fixed contact piece and having a communication hole, and a pressing part that causes the movable contact piece to approach and separate from the fixed contact piece through the communication hole by the switch operation. In the push button switch, a push button switch is provided with a presser plate and a presser plate stacked together as a unit, a gap is formed between the upper and lower edges of the movable contact piece and the communication hole, and a gap is formed between the upper and lower edges of the movable contact piece and the communication hole; A projecting piece extending below the main body case is provided, and a notch is formed in the frame body to closely face each other so that the projecting piece is fitted into the frame, and the projecting piece and the recessed step allow the opening to be removed from the opening. A push button switch characterized in that an air flow path communicating with the movable contact piece is formed on a surface thereof.
