Claims

[Scope of utility model registration request]

a plurality of fixed contacts exposed in the case; movable contact pieces arranged in parallel with each other and each corresponding to the fixed contact; and a surface facing the movable contact pieces serving as a cam surface, which is rotatable; and a rotor that selectively engages and disengages the locking portion of the cam surface with the locked portion of each movable contact piece, and by rotating the rotor, the movable contact piece is brought into contact with and separated from the corresponding fixed contact. In the rotary switch, a cam surface of the rotor is provided with a first locking portion having the same rotation radius and extending in the circumferential direction of the rotor, and a second locking portion extending in the radial direction of the rotor. ,and,
The plurality of movable contact pieces include at least a movable contact piece provided with a first locked part that engages and disengages the first locking part, and a second cover that engages and disengages the second locking part. A rotary switch comprising a movable contact piece provided with a locking part.
