[Scope of Claim for Utility Model Registration] A switch box that houses a switch main body, a shaft hole into which a rotating shaft fixed to one side of the switch box and whose rotational position corresponds to the operating state of the actuator is inserted, and the rotating shaft. a head portion formed by intersecting a spring hole into which a return spring that engages with the shaft and returns the actuator to its initial position is supported on one side of the switch box so as to be able to reciprocate; The other end of the actuator engages with an operating button on the switch body to connect the two, and when the actuator returns to its initial position, it moves when pressed by the operating button that performs the return operation, and the rotating shaft and a flexible seal member interposed between the outer periphery of one end of the linking member and one side of the switchbox to isolate the switchbox and the head portion, the limit switch comprising: A communication hole is formed in the head portion to communicate the space formed by the shaft hole and the spring hole with the outside, and the communication hole is closed with a sealing member that has air permeability and can prevent the passage of liquid. Limit switch.
