Claims

[Scope of claims for utility model registration] (1) A casing having an opening and housing an internal mechanism;
It protrudes from the opening of this casing and is O from the outside of the casing.
An operating handle that can be operated in the N and OFF states, a link that is rotatably connected at one end to the operating handle and forms a toggle link mechanism together with the operating handle, and a link that is rotatably supported and has a fixed contact at one rotating end. a movable element having a movable contact placed opposite to the movable element, which is rotatably attached to the movable element, and the other end of the link is always held between the movable element and the link so that the movable element and the link are connected; When the locking lever is turned on and an overcurrent of more than a specified value flows,
In a circuit or disconnector equipped with an overcurrent tripping device that disconnects the link and the movable element to separate the movable contact from the fixed contact, the overcurrent tripping device disconnects the overcurrent. When the operation handle is removed, the operation handle is
A circuit switch or disconnector characterized in that the housing is provided with a stopper for preventing movement of the locking lever so that it is in an intermediate position between N and OFF. (2) The circuit breaker according to claim 1, wherein the stopper is made of an elastic body. (3) The circuit breaker or breaker according to claim 1 or 2 of the utility model registration claim, in which the stopper is integrally formed with the casing.
