摘要： A circuit interrupter comprising a pair of separable contacts at least one of which is movable, and an operating mechanism operatively connected to the movable contacts for opening and closing the contacts. The operating mechanism includes a movable contact arm having mounted thereon the movable contact, a latch lever pivotally mounted on the movable contact arm, and a toggle link mechanism connected at its one end to an operating handle and the other end of which is directly engageable with the movable contact arm and the latch lever. The movable contact arm has a latch surface, and the latch lever has a latching end which, in cooperation with the latch surface, releasably catches the other end of the toggle link mechanism. The movable contact arm further has formed thereon a stop surface for preventing the movement of the other end of the toggle link mechanism beyond the point at which the toggle link mechanism is partly collapsed when the contacts are welded to each other. A roller may be mounted on the other end of the second toggle link for quick and smooth operation of the operating mechanism.
