    • A switch device with a greatly strengthened limit structure where damage in the limit structure can be quickly detected and the structure can be easily replaced. The switch device includes a housing; a rotating shaft supported inside the housing and rotatable around its axis; a sway rod outside the housing, which is mounted at the end of the rotating shaft and configured to sway around the rotating axis of the rotating shaft by an external force applied outside the housing; a movable part outside the housing, which is configured to rotate together with the sway rod around the rotating axis of the rotating shaft; and a limit bearing part outside the housing and fixed relative to the housing, when the movable part is abutted on the limit bearing part, the swaying of the sway rod is limited, and the rotating shaft stops rotating.
    • 具有大大加强的极限结构的开关装置,可以快速检测限位结构的损坏,并且可以容易地更换结构。 开关装置包括壳体; 旋转轴,其支撑在壳体内并可围绕其轴线旋转; 壳体外部的摆动杆,其安装在旋转轴的端部并且构造成通过施加在壳体外部的外力围绕旋转轴的旋转轴线摆动; 壳体外部的可移动部件,其构造成与所述摇摆杆一起围绕所述旋转轴的旋转轴线旋转; 以及限制轴承部分,并且相对于壳体固定,当可动部分抵靠在极限轴承部分上时,摇摆杆的摆动受到限制,旋转轴停止转动。
