    • The present disclosure aims to provide a high-durability switch device. The switch device includes: a switch key top and a switch key bottom that are freely displaceable relative to each other, the switch key top including key top reception and transmitting coils that are connected to each other, and the switch key bottom including: a key bottom transmitting coil having a relative positional relationship with the key top receiving coil that changes according to a relative displacement operation with respect to the switch key top; a key bottom receiving coil having a relative positional relationship with the key top transmitting coil that changes according to the relative displacement operation with respect to the switch key top; a current supplier supplying current to the key bottom transmitting coil; and a determiner determining relative displacement with respect to the switch key top from induced current in the key bottom receiving coil.
    • 本公开旨在提供一种耐久性高的开关装置。 开关装置包括:可相对于彼此自由移动的开关键顶部和开关键底部,开关键顶部包括彼此连接的键顶接收和发送线圈,开关键底部包括:键 所述底部发射线圈与所述键顶接收线圈的相对位置关系根据相对于所述开关键顶部的相对位移操作而改变; 具有与所述键顶发送线圈的相对位置关系的按键底部接收线圈根据相对于所述开关键顶部的相对位移操作而变化; 供应给钥匙底部发射线圈的电流的当前供应商; 以及确定器,其确定相对于开关键顶部的关键底部接收线圈中的感应电流的相对位移。
