Claims

[Scope of utility model registration request]

A torque limit switch mechanism that operates one of the corresponding torque switch suppressors to switch the corresponding main limit switch when the torque acting on the output shaft of the valve actuator body reaches one of the set limit values. a position limit switch mechanism that operates a corresponding position switch pusher to switch a sub-limit switch when the operating position of the output shaft reaches any set limit position; The position switch is provided between each child switch pusher of the switch mechanism and the corresponding switch and pusher of the torque limit switch mechanism, and when the position switch pusher is operated to the switch switching position, the torque switch a pusher engagement/disengagement switchable between a state in which it engages with a pusher and allows the torque switch pusher to follow the position switch pusher and a state in which it cannot engage with the torque switch pusher; What is claimed is: 1. A switching device for an actuator, characterized by comprising a mechanism.
