Le premier élément métallique (1-1) et le second élément métallique (2) sont parallèles l'un à l'autre, et il y a un espace entre eux, et l'espace est rempli d'un matériau diélectrique (7) ayant une constante diélectrique élevée. Lorsque le bouton de commutation (3) est pressé, un signal est envoyé à la carte de commande électrique (4) lorsque la capacité entre le premier élément métallique (1-1) et le second élément métallique (2) détecté par la puce de détection de capacité (14) atteint un seuil prédéfini, et la carte de commande électrique (4) commande le fonctionnement du dispositif électronique. Les problèmes d'une structure de commutation compliquée, d'un grand volume et de coûts élevés de dispositifs électroniques dans l'état de la technique sont résolus. Un commutateur destiné à un dispositif électronique est mis en œuvre, tandis que les coûts et l'investissement sont réduits, et le volume du dispositif électronique est réduit, facilitant le transport et le placement, et améliorant l'expérience utilisateur.
