A radio telephone device (1) is provided with a reed switch (13) arranged between a radio section (12) and a rod antenna (15) in a telephone set main body (10), which connects the radio section (12) and the rod antenna (15) with each other when the telephone set main body (10) is separated from a car kit (20). The car kit is provided with a magnet (27) which magnetically energizes the reed switch (13) when the telephone set main body (10) is placed on the car kit (20) so that the reed switch (13) is turned into a mode where the radio section (12) and an external antenna (26) are connected to each other. Hence it is possible to execute switching the antenna line between the rod antenna (15) of the telephone set main body (10) and the external antenna (26) of the car kit (20) without inviting any increase in the consumption of electric current and without making the circuits more complicated.
Un dispositif radiotéléphonique (1) est muni d'un commutateur à lames (13) disposé entre une section radio (12) et une antenne tige (15) dans un corps principal d'appareil téléphonique (10), qui connecte entre elles la section radio (12) et l'antenne tige (15) lorsque le corps principal d'appareil téléphonique (10) est séparé d'un support pour voiture (20). Le support pour voiture comprend un aimant (27) qui, lorsque le corps principal d'appareil téléphonique (10) est placé sur le support pour voiture (20), active magnétiquement le commutateur à lames (13) de sorte qu'il (13) connecte entre elles la section radio (12) et l'antenne extérieure (26). Il est ainsi possible de commuter la ligne d'alimentation d'antenne entre l'antenne tige (15) du corps principal d'appareil téléphonique (10) et l'antenne extérieure (26) du support pour voiture (20) sans consommation électrique supplémentaire et sans compliquer les circuits.
