Механизм содержит расположенный внутри корпуса, подпружиненный в направлении выключения ручной исполнительный вороток, с которым с возможностью поворота шарнирно соединен рычаг. На него при включении опирается против усилия пружины поворачивающийся вокруг оси контактный рычаг. Он воздействует на неподвижный контакт и напрягается в положении замыкания с самофиксацией против усилия пружины. Целью изобретения является упрощение опорного соединения между рычагом и контактным рычагом для достижения равномерных усилий срабатывания с небольшим разбросом в пределах одного типа выключателя. Для этой цели между воротком и контактным рычагом расположен образованный выпрямляющим рычагом и хомутом коленчато-шарнирный рычаг, который в стабильном положении почти выпрямлен и за счет формы выпрямляющего рычага занимает точно определенное положение за мертвой точкой обоих своих плеч. Рычаг действует при включении и во включенном положении как жесткий рычаг. За счет нагрузки его шарнира приблизительно под прямым углом расщепляющим рычагом в направлении мертвой точки рычаг попадает в нестабильное положение под действием контактного рычага, поворачивающегося обратно за счет усилия пружины. Это устраняет жесткое соединение между воротком и контактным рычагом, в результате чего плечо со стороны контакта может повернуться в свое разомкнутое положение. Механизм согласно изобретению особенно пригоден для автоматов дифференциальной защиты и линейных защитных автоматов.The mechanism contains a manual executive knob located inside the housing, spring-loaded in the direction of shutdown, with which the lever is pivotally connected. When switched on, it is supported against the force of the spring by a rotating lever pivoting around an axis. It acts on the fixed contact and is strained in the closed position with self-locking against the spring force. The aim of the invention is to simplify the reference connection between the lever and the contact lever to achieve uniform tripping forces with a small variation within the same type of switch. For this purpose, between the crank and the contact lever there is a crank-hinged lever formed by a straightening lever and a yoke, which is almost straightened in a stable position and, due to the shape of the straightening lever, occupies a precisely defined position beyond the dead point of both its shoulders. The lever acts when switched on and in the on position as a rigid lever. Due to the load of its hinge approximately at right angles by the splitting lever in the direction of the dead point, the lever falls into an unstable position under the action of a contact lever turning back due to the spring force. This eliminates a rigid connection between the driver and the contact arm, with the result that the shoulder on the contact side can turn to its open position. The mechanism according to the invention is particularly suitable for automata differential protection and linear circuit breakers.
