Abstract
An actuator of the present invention comprises an operation key 2 to be inserted into a key insertion hole formed in the safety switch, and a base 3. The operation key 2 is held on the base 3 and capable of freely swinging in two orthogonal directions. The actuator also comprises means (e.g. a guide stopper 4 and engagement spaces 34) for selectively restricting the swinging movement of the operation key 2 to either of the two directions.
Claims5
