(54) Rotary switch device


(57) The wave-shaped guide portion (18) is arranged in the knob (12), and the contact holders (19, 20) are arranged so that they can be individually, linearly moved together with the movable contacts (23, 24) by the protrusions (21, 22) moved in the guide portion (18) according to the rotation of the knob (12). Due to the foregoing, a different state of connection of the movable contacts (23, 24) with the fixed contacts (26 to 28) is successively realized by a linear reciprocating motion of the plurality of individual contact holders (19, 20) according to the rotation of the knob (12).
