Switch (Donkey Kong)

Switches are lever-like objects that appear in Donkey Kong for the Game Boy. They are used to control conveyor belts, moving platforms, and elevators. They can also be used to make bridges appear and disappear, as well as opening and closing gates. To operate a switch, the player must hold while Mario is near the switch, then move the  Control Pad either left or right to push and pull the switch. In some boss stages, Donkey Kong Jr. also operates switches to hinder Mario's progress.

Similar objects, known as Direction Switches and conveyor switches, appear in games from the Mario vs. Donkey Kong series.
