Claims

[Scope of utility model registration request]

a housing having an opening and housing an internal mechanism; a housing that protrudes from the opening of the housing and is turned on from the outside of the housing;
An operating handle that can be turned OFF and always biased in the OFF direction by a first torsion spring, a link whose one end is rotatably connected to the operating handle, and which forms a toggle link mechanism together with the operating handle; It is movably supported and has a movable contact arranged opposite to the fixed contact at one rotating end, the other rotating end is always connected to the link, and the movable contact is connected to the fixed contact. A movable element that interlocks with the link so as to move toward and away from the link, and an overcurrent tripping element that disconnects the link and the movable element and separates the movable contact from the fixed contact when an overcurrent exceeding a predetermined value flows. the device and the operating handle, and is attached in the ON direction so that the operating handle is in an intermediate position between the ON and OFF when the overcurrent trip is caused by the overcurrent tripping device. a second torsion spring that biases the operating handle and prevents movement of the operating handle;
