摘要

There is provided a housing comprising an electrically powered device and electrical connecting means. The (electrical connecting means of the) housing fits an interface means of an electrical power supply. The housing is provided with one or more protruding elements movable between an idle position and a depressed position. In the idle state the one or more protruding elements prevent an electric current from passing between the electrical connecting means and the electrically powered device. The interface means comprise a front side which interacts with the one or more protruding elements by pushing the one or more protruding elements into the depressed state, thereby enabling an electric current to pass between the electrical connecting means and the electrically powered device exclusively when the housing has been properly installed.
