  • FIG. 15 by fixing the magnets 32 having opposite polarities to the adhesive base 16 and the knob base 25 and connecting the magnets 32 to each other, a structure in which the connecting force is suppressed can be realized.
  • the FPC 24 can be temporarily fixed to the adhesive base 16 to prevent disconnection of the FPC 24 when the knob assembly 17 comes off the adhesive base 16.
  • connection force between the adhesive base 16 and the knob assembly 17 is set so that the knob assembly 17 is detached from the adhesive base 16 before the knob assembly 17 affects the CID. It is possible to reliably prevent the CID 4 from being destroyed even when a large external force is applied.
  • the configuration may be such that the central portion of the switch device is closed.
  • the switch device may be provided on a display other than CID4.
  • the switch device may have a configuration capable of performing only a pressing operation, a configuration capable of performing a swinging operation or a sliding operation, or a configuration having a combination thereof.
