and a second push button, and the switch case is provided with first and second fixed contact pieces and, alternatively, a movable contact piece that contacts each of these fixed contact pieces, The movable contact piece has a cam surface formed across the swinging fulcrum of the movable contact piece, and the first
Each of the push buttons is provided with an actuation piece that slides on the cam surface of the movable contact piece, and in conjunction with the pressing operation of the first push button, the contact position of the actuation piece with respect to the cam surface is adjusted to the pivot point. The movable contact piece is selectively switched to opposing positions where the movable contact piece is swung toward the first and second fixed contact sides, and the first push button is placed between the second push button and the movable contact piece. An interlocking mechanism that prevents the swinging of the movable contact piece at a neutral position when a single push button is pressed, and allows contact with the first fixed contact piece when the first and second push buttons are pressed. A switch that features a cam.
