エータ用スイッチング装置。A position limit switch that has an input shaft into which changes in the operating position of the valve actuator body are input, and detects whether or not the operating position has reached a set limit position set at both ends of the stroke based on the movement of the input shaft. a torque limit switch mechanism that rotates a switch pusher in either direction to switch the corresponding switch when the torque acting on the valve actuator body reaches a set limit value; a rotating surface that is provided so as to be able to rotate in forward and reverse directions and has retaining portions at both ends in the rotation direction; and a rotating surface that is provided in elastic contact with this rotating surface and when the switch pusher is rotated to a switch switching position. a locking pawl that engages with the engaging portion to prevent the switch pusher from returning; and a locking pawl that is provided on the input shaft via a slipping clutch so that the input shaft is opposite to the direction of the switching operation by the switch pusher. 1. A switching device for a valve actuator, comprising: a reset mechanism that temporarily follows the input shaft to detach the retaining pawl from the retaining portion when the input shaft is rotated in the direction of rotation.
