SAFETY SWITCH

摘要

A safety switch capable of securely switching the opening/closing states of switches installed in a lock mechanism in association with the movement of a lock body between a lock position and an unlock position. The safety switch comprises a link body (81d) directly and simultaneously switching the opening/closing states of normally open and normally closed switches (85) and (86) according to the movement of the lock body (80). Accordingly, the safety switch can securely switch the opening/closing states of the normally open and normally closed switches (85) and (86) in association with the movement of the lock body (80) between the lock position and the unlock position. As a result, for example, by monitoring the opening/closing states of the normally open and normally closed switches (85) and (86), a user can discriminate to which of the lock position and the unlock position, the lock body (80) is moved, namely, in which of the lock state and unlock state, a drive cam (15) is rotated.
