1. A rotary switch device for a vehicle, the rotary switch device comprising:
a rotary dial module including a plurality of sensors and a material configured to react to a magnetic force; and
a base module configured to generate a magnetic force greater than or equal to a threshold value to enable the rotary dial module to be attached to the base module and transmit detection results from the plurality of sensors included in the rotary dial module to an electronic device inside the vehicle when the rotary dial module is attached to the base module;
wherein the base module comprises a magnetic coil configured to generate the magnetic force according to a received current; and
wherein the rotary dial module is detached from the base module when the magnetic force generated by the magnetic coil is less than the threshold value.
