PROBLEM TO BE SOLVED: To provide a fluid pressure operating device which is for a switch for power and is capable of easily monitoring the drive force of an accumulator. SOLUTION: In the neighborhood of a control rod 47, a plurality of micro- switches 101 are stacked in stages in the direction parallel with the operating axis of a control rod 47 and securd by a plate from above using a stud 102 and nut 104. They 101 are arranged in rows in the circumferential direction of the control rod 47. A roller 101b capable of contacting with and separating from the side face in compliance with the movement of the rod 47 is attached to the tip of a knob 101a furnished on each micro-switch 101. An indicator needle 106 is installed at the tip of the rod 47 using a rotational pin 107, and near the tip of the needle 106, two scale plates 108 are fixed which are equipped with graduations in the direction parallel with the operating axis of the rod 47. |
