Claims

[Scope of utility model registration request]

An electrical signal obtained by pressing any one of the plurality of range select buttons is applied to the controller, so that the controller automatically controls the transmission in the shift range for which the button is operated. In a push-button automatic transmission, a selection type automatic transmission is activated by pressing a reverse range select button, which is one of the range select buttons, and is mechanically held as long as no other range select button is pressed. A second switch of an automatic return type, which is activated by pressing a safety button provided separately from each of the range select buttons, is connected in series to one switch, and which is activated by the operation of both of the switches. A self-holding third switch is connected to the second switch, and the third switch is electrically held while the first switch is activated and cooperates with the first switch to apply a reverse range electrical signal to the controller. An operating device for a push-button automatic transmission characterized by being connected in parallel to the push-button automatic transmission.
