Le dispositif de commutation comprend un boîtier, un composant de flambage et un module de transformation de tension ; le composant de flambage est disposé sur le boîtier ; le composant de flambage comprend une première boucle et une deuxième boucle ; une rainure est formée au niveau d'une extrémité libre de la première boucle ; la deuxième boucle est pourvue d'une partie crochet, et la partie crochet est disposée au niveau d'une extrémité libre de la deuxième boucle ; un trou de connexion de câble d'attache et une interface de sortie de tension sont formés sur le boîtier ; le module de transformation de tension est disposé dans le boîtier ; une extrémité de connexion de câble d'attache est disposée sur le module de transformation de tension ; le module de transformation de tension est connecté à l'interface de sortie de tension ; le trou de connexion de câble d'attache est en communication avec l'extrémité de connexion de câble d'attache ; et l'ouverture de la rainure fait face à l'interface de sortie de tension. En adoptant la structure décrite, le dispositif de commutation peut être monté et démonté rapidement ; et en montant ou démontant le dispositif, la commutation entre un mode captif et un mode non-captif de l'aéronef sans pilote est mise en œuvre.
