An arcade controller is a collective set of input devices designed primarily for use in an arcade cabinet. A typical control set consists of a joystick and a number of push-buttons. Less common setups include devices such as trackballs or steering wheels. These devices are generally produced under the assumption that they will be used in commercial settings, such as in video arcades, where they may be heavily or roughly used. Durability is one of the distinguishing characteristics of "authentic" arcade parts when compared with numerous, low-cost arcade imitations designed for private use in the home.
