Un mode de réalisation de la présente invention concerne une structure de touche de fonction, ladite structure de touche de fonction comprenant une base (10), une touche de fonction (20), un premier ensemble de détection (30), un élément élastique (40), et un second ensemble de détection (50), la base (10) comprenant une cavité de réception (101) ; la touche de fonction (20) comprenant une partie d'actionnement (201) et un arbre rotatif (202) qui s'étend à partir de la partie d'actionnement (201) vers la base (10), et la partie d'actionnement (201) entraîne l'arbre rotatif (202) pour tourner ou effectuer un mouvement axial vers la base (10) ; le premier ensemble de détection (30) est disposé autour de l'arbre rotatif (202) et utilisé pour acquérir des informations d'état de rotation de l'arbre rotatif (202) ; et l'élément élastique (40) et le second ensemble de détection (50) sont disposés dans la cavité de réception (101), l'élément élastique (40) fournit une force de support et de restauration pour la touche de fonction (20), et le second ensemble de détection (50) détecte le mouvement axial. La structure de touche de fonction fournie dans le mode de réalisation de la présente invention met en œuvre les fonctions de sélection et de confirmation qui sont obtenues au moyen de la même touche de fonction, a une structure compacte, occupe moins d'espace, et améliore simultanément l'expérience d'opération d'un utilisateur. En outre, selon un autre mode de réalisation, la présente invention concerne un dispositif électronique qui utilise la touche de fonction.
