What is Kill switch?
[[File:Not-Aus Betätiger.jpg|thumb|A Kill switch]] A '''kill switch''', sometimes called an '''emergency stop''', is a part of a [[user interface]]. User interfaces allow people to operate [[machine]]s. The kill switch is there for [[security]]. Its purpose is to switch off the machine as quickly as possible, or to bring it into a state where it can no longer do harm. It is used in an [[emergency]]. In many ways, switching off the machine in an emergency is different from switching it off normally, as it has to avoid injury or harm '''at all costs'''. {{stub}} [[Category:Safety]] [[Category:Engineering]]
