Claim 15:
16. A safety switch having a lock mechanism for locking a bolt of an actuator including a transponder, comprising:
a casing having a shape elongated along a first direction;
a head coupled to a first end side of the casing in the first direction, and having a receiving space for receiving the bolt of the actuator, and a first attachment hole formed along a second direction orthogonal to the first direction;
a wireless circuit disposed in the casing to receive a wireless signal from the transponder;
