Abstract: An operating mechanism for a combined interrupter and disconnect switch (10, 11) comprises an operating linkage (17) and an interrupter support housing (41) rotated separately about a common pivotal axis. The interrupter switch (10) is part of a disconnect switch arm and is secured to the support housing. The interrupter contacts are operated by a linearly movable rod (40) which has an end connected to a lever (56) extending from the operating crank (55) and is movable thereby. A linearly movable operating shaft (21) is connected to and moves a crank arm (57). A spring biased latch lever (80) is pivotally mounted to the interrupter support housing and releasably engages the free end of the crank arm lever (56) so that the housing rotates with the crank and closes the disconnect switch (11). When the disconnect switch closes, the latch lever (80) releases and the crank (57) rotates relative to the housing to operate the linearly movable rod (40) which operates the interrupter switch (10).

Abstract translation: 用于组合式断路器和断开开关（10,11）的操作机构包括操作联动装置（17）和围绕公共枢转轴线分别旋转的断流器支撑壳体（41）。 断路器开关（10）是断开开关臂的一部分并被固定到支撑壳体上。 断路器触点由线性可动的杆（40）操作，该杆（40）的端部连接到从操作曲柄（55）延伸的杆（56），并且由此可移动。 线性移动的操作轴（21）与曲柄臂（57）连接并移动。 弹簧偏压的闩锁杆（80）枢转地安装到断续器支撑壳体上并且可释放地接合曲柄臂杆（56）的自由端，使得壳体与曲柄一起旋转并且关闭断开开关（11）。 当断开开关闭合时，闩锁杆（80）释放并且曲柄（57）相对于壳体旋转，以操作操作断续器开关（10）的线性可动杆（40）。
