Claims

[Scope of utility model registration request]

A limit switch is a limit switch that is housed in a casing and opens and closes in conjunction with the rotation of a main shaft whose one end protrudes from the casing. An arm formed by bending the arm is attached by inserting the main shaft into the through holes formed in each of the legs so that the legs of the arm are parallel to the axis of the main shaft. The arm is fixed to the main shaft by the tip of the fixing screw screwed into the screw hole drilled in the leg piece coming into contact with the circumferential surface of the main shaft, and the screw head of the fixing screw protruding outward from the leg piece of the arm touches the circumferential surface of the main shaft. The Mitsutwitch has an indicator on the surface of the casing that indicates the range in which the switch can operate properly, corresponding to the range of movement as the main shaft rotates.
