description 1 Field of the Invention A mobile telephone including a housing () containing an electrical circuit () and carrying a cover () fastened to the housing in an articulated manner. The telephone also comprises a microphone and rotary contacts incorporated in one of the two joints connecting the cover () to the housing (), in order to make electrical connections between the electrical circuit () and the microphone. One of the joints () articulating the housing on the cover comprises three contacts integral with the housing, namely two lateral contacts () and () and a central contact (), each comprising a contact arm (), () and (). The central contact () bears permanently on a conductive element (), while the ends of the two lateral contact arms () and () bear elastically on two conductive plates (). The plates are separated by an insulating material () and incorporated in the part () of the joint of the cover (), in such a way that, when the cover is rotated, the ends of the two contact arms (), () ensure that the electrical connection between the electrical circuit () and the microphone is switched.
