They're designed to enhance electrical safety in industrial applications, but can also be used in commercial environments. It features a mechanical interlock that prevents the switch from closing if the plug is not inserted and also prevents the extraction of the plug if the switch is closed, and the opening of the socket outlet cover if the switch is closed.
