A disconnecting switch includes a contact part that includes a stationary contact and a movable contact, a shaft that moves the movable contact relative to the stationary contact, an open/close mechanism part that moves the shaft back and forth freely between a closed contact position at which the movable contact contacts with the stationary contact and an open contact position at which the movable contact is separated from the stationary contact, and a housing that houses at least the contact part and the shaft. The open/close mechanism part includes an operation lever, an arm that rotates according to an operation of the operation lever to move the shaft between the open contact position and the closed contact position, and a wheel rotatably attached to the housing. The arm has a rotation slot in which the wheel is placed so that the wheel moves when the arm rotates.

A circuit breaker includes a main body case, an operating handle having a base portion and a knob portion protruding outwardly through a handle window frame opened in a cover of the main body case; a first shutter arranged between the base portion of the operating handle and the handle window frame, and disposed on the base portion, the first shutter being formed with a loose-fit hole to loosely fit the knob portion therethrough; and a second shutter disposed on the first shutter to move along with the knob portion. At ON and OFF positions of the operating handle, the first shutter extends beyond a front/rear edge of the handle window frame in a front-back direction to close the handle window frame, and the second shutter extends beyond a front/rear edge of the loose-fit hole in the front-back direction to close the loose-fit hole.

An interface assembly is for a trip unit of an electrical switching apparatus including a housing, separable contacts, and an operating mechanism for opening and closing the separable contacts. The trip unit cooperates with the operating mechanism and includes an enclosure, a controller, and a cover member having a plurality of indicia. The interface assembly includes at least one adjustment knob assembly having a post member and a ring member, which includes a cutout. The post member has first and second opposing ends. The ring member is disposed on the second end. The adjustment knob assembly pivots among a plurality of positions to adjust the controller. Each position corresponds to a predetermined setting of the trip unit. The ring member substantially overlays all but one of the indicia, which is exposed by the cutout to indicate the adjustment knob assembly position and corresponding trip unit setting.
