摘要： A cam (22) of a safety switch (1) rotates about a rotational shaft (221) in accordance with an operation of inserting an actuator (10) into an opening (213) and an operation of withdrawing the actuator (10). A switch part (32) includes an operation rod (321) that reciprocates according to a rotation angle of the cam (22), and detects an insertion state where the actuator (10) is inserted in the opening (213). In the insertion state, a locking member (25) locks the actuator (10) upon engagement with a part of the cam (22). When the operation of withdrawing the actuator (10) is performed in a locked state of the actuator (10), the cam (22) pushes the locking member (25) in one direction, and the locking member (25) pushes a part of a head case (21) in the one direction. This improves locking strength of the safety switch (1).

摘要： When an initial position of an enabling switch is given as a first position (301), a position of the enabling switch in which a movable member is most pressed is given as a third position (303), and a rising start position of a maximum rise of a load is given as a second position (302), the rising start position being between the first position (301) and the third position (303), a minor peak (341) of the load appears between the first position (301) and the second position (302). An ON switching position (311) is between a falling start position (323) of the minor peak (341) and the second position (302). A maximum load during the minor peak (341) is greater than or equal to the load in the ON switching position (311) and less than or equal to the load in an OFF switching position (312).

摘要： In an actuator unit, a slide base can be not only locked easily relative to a fixed base but also made a secure locking state in which the slide base cannot move relative to the fixed base by an operation from the outside. The actuator unit (2) includes a fixed base (2A) to be fixed at a movable door (D), a slide base (2B) having an actuator (20) and provided slidable at the fixed base (2A) , a first locking means (26C 1 , 27) that locks the slide base (2B) in a first locking state relative to the fixed base (2A) in a retreat position of the actuator (20), an unlocking means (26A, 26B, 26C) that can unlock the first locking state, and a lock or a second locking means (22) that causes the slide base (2B) to be unable to move relative to the fixed base (2A) by an operation of a key (22a).

摘要： A cam (22) of a safety switch (1) rotates about a rotational shaft (221) in accordance with an operation of inserting an actuator (10) into an opening (213) and an operation of withdrawing the actuator (10). A switch part (32) includes an operation rod (321) that reciprocates according to a rotation angle of the cam (22), and detects an insertion state where the actuator (10) is inserted in the opening (213). In the insertion state, a locking member (25) locks the actuator (10) upon engagement with a part of the cam (22). The locking member (25) includes a coupling part (26, 52) that is coupled to and moves with the rod (321). The unlocking part unlocks actuator upon movement of the rod (321) that is independent of rotation of the cam (22). This improves locking strength of the safety switch (1).
