Claims

[Scope of utility model registration request]

The outer pattern consists of a contact pattern and a drawer pattern, and the drawer pattern consists of a rising part rising from the end of the contact pattern and an arc part extending from the rising part in the extending direction of the contact pattern. In a rotary switch consisting of a contact pattern and a pull-out pattern, and the pull-out pattern includes a rising part rising from an end of the contact pattern and an arcuate part extending from the rising part in the extending direction of the contact pattern, the inner pattern is arranged to be shifted from the outer pattern in the extension direction of the outer contact pattern, and the resist covering the inner drawer pattern is positioned in the space defined by the arc portion and the rising portion of the outer drawer pattern. Features rotary switch.
