1. 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 metal 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;
a lock pin in the lock mechanism, configured to regulate pull-out of the bolt from the receiving space by disposing at a lock position in a lock state, and configured to allow pull-out of the bolt from the receiving space by disposed at an unlock position in an unlock state, the lock pin being switchable between the lock position and the unlock position; and
