Abstract
A rotary switch permits the interrelation between the angle of rotation of a rotary switch knob and the angle of integral rotation of a rotor and a contact spring to be set as desired. A rotary switch knob and a rotor are respectively provided with a first gear and a second gear, and are linked together by these gears. The rotor carries a contact spring fixed thereto. When the ratio between the respective teeth numbers of the first and second gears is suitably set, the interrelation between the rotational angle of the rotary switch and that of the rotor and the integral contact spring can be set as desired.
