ッチ。[Claim for Utility Model Registration] In a rotary switch that can be switched in multiple stages, a cam that operates a movable switch contact piece is formed integrally with an operating shaft,
A key-shaped protrusion that abuts against the outside of the base (casing) is provided on the peripheral surface of the operating shaft, and a protruding stopper is formed on the outer periphery of the cam. Further, an operating shaft fitting hole is provided in the base, a key groove into which the key-shaped protrusion can be inserted is formed at a position outside the predetermined rotation angle range of the operating shaft, and the cam A stopper protrusion is provided on the inner surface of the part corresponding to the outer periphery protrusion-like stopper, and the key-shaped protrusion of the operating shaft is inserted through the operating shaft fitting hole key groove, and the corresponding stopper is rotated while being bent to a predetermined position. A rotary switch that can be easily assembled into the desired position.
