Claims

[Scope of utility model registration request]

In a switch operation handle that is fork-connected to an opening/closing mechanism that opens and closes a contact device housed in a case with a two-part structure and swingably protrudes above the case, the case is divided into upper and lower parts, and an upper case is provided. an opening provided on the upper side through which the operating handle can be coupled to the opening/closing mechanism; and locking protrusions protruding from both inner walls of the opening parallel to the operating handle swinging direction and facing each other and having elasticity. a semi-cylindrical support shaft extending toward the string side, a semicircular recess that can be fitted into each of the support shafts from the outside of the opening, and the locking protrusion piece provided on the string side of the semicircular recess. An operating handle for a switch, characterized in that recesses that can be engaged with are provided on both sides of the boss.
