Abstract

L'invention concerne un dispositif de commutation pourvu d'une unité de commutation qui est actionnée lors de l'actionnement d'une cible d'actionnement. Ce dispositif de commutation est pourvu d'une première antenne 33 qui est apte à une première communication sans contact avec une étiquette électronique à une fréquence prescrite, et une seconde antenne 34 qui communique avec une autre étiquette électronique différente de l'étiquette électronique susmentionnée dans une seconde communication sans contact à une fréquence différente de celle de la première communication sans contact. Les résultats de communication de la première communication sans contact et de la seconde communication sans contact sont un état pour l'actionnement de la cible d'actionnement. La première antenne et la seconde antenne sont toutes deux disposées dans l'unité de commutation.
