としたスイツチ。 The first button is pressed separately into the switch case.
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 first push button moves the movable contact piece to the second push button.
The contact between the second push button and the movable contact piece is connected so as to be switchable from contact with the fixed contact piece to contact with the first fixed contact piece, and an individual pressing operation of the first push button is provided between the second push button and the movable contact piece. An interlocking mechanism is provided which prevents the movable contact piece from swinging at a neutral position when the movable contact piece is in a neutral position, and allows the swinging until it comes into contact with the first fixed contact piece when the first and second push buttons are pressed. A switch that is characterized by the fact that it becomes
