ABSTRACT:
A combination switch device having a rotating connector (2) containing a spirally wound flexible wire (1), a cancel cam (3) arranged about a central axis of the rotating connector (2), and a combination switch main body (4). The cancel cam (3) is movable in an axial direction between a first position (S) and a second position (R). When the cancel cam (3) moves to the first position (S), a bear (31) of the cancel cam (3) engages with a claw (41) of the combination switch main body (4). At the same time, a convex portion (32) of the cancel cam (3) engages with a concave portion (23) of a rotor attachment (22) attached to a rotor (21), whereby the rotor (21) is held at a neutral position. Thus, the rotating connector can be held at a neutral position without requiring special parts by modifying an existing structure of a combination switch device having a rotating connector.
