Document Type and Number:
Japanese Patent JP2006324087
Kind Code:

Abstract:

To provide a safety switch capable of preventing certainly advance of an actuator into a switch body when such an abnormality that a lock mechanism of the safety switch in locking state cannot lock a drive cam, is generated.

When a lock 802d is broken by pulling an actuator forcibly while rotation of a drive cam 15 is in locked state and the drive cam 15 becomes rotatable, the top end 802j2 of a moving body 802j is locked to a locking part 15d and rotation of the drive cam 15 is prevented. Therefore, when the lock 802d is broken and such an abnormality that the drive cam 15 cannot be locked regularly, is generated, even if the actuator 3 is tried to be advanced into the operating part 5, advance of the actuator 3 into the switch body 1 can be certainly prevented.
