    • A rotary switch (4) comprising a body (8) housing inside itself a rotating shaft (12) operatively connected to a valve or actuator. The switch (4) further comprises a cover (20), associated to the body (8) by threaded coupling means (36), provided with an indicator (28) swivelling integrally with the shaft (12), so that it enables visual signalling of the angular position and/or operating status of the shaft (12). The switch (4) comprises centering means (56), mechanically distinct from the threaded coupling means (36), which ensure the centering of the cover (20) in relation to the body (8) and the coaxial relation between the cover (20) and the rotating shaft (12).
    • 旋转开关(4)包括主体(8),壳体内部容纳有可操作地连接到阀或致动器的旋转轴(12)。 开关(4)还包括通过螺纹联接装置(36)与主体(8)相关联的盖(20),其设置有与轴(12)一体地旋转的指示器(28),使得其能够进行视觉信号 轴(12)的角位置和/或操作状态。 开关(4)包括与螺纹联接装置(36)机械地不同的定心装置(56),其确保盖(20)相对于主体(8)的定心和盖(20)之间的同轴关系 )和旋转轴(12)。
