Only the launch push buttons are momentary. The toggle switches are standard. Two things drove my choice. One was the cost (standard toggles are considerably less expensive). The other was to facilitate drag races. This allows the user to select each of the active pads and then push the individual launch buttons to intiate launch. I felt that this could be done because of the additional monitors placed on the switch states allowing the user to assess the status of each of switches before final selections are made.
