Title:
SAFETY SWITCH
Document Type and Number:
WIPO Patent Application WO/2018/155335
Kind Code:
A1
Abstract:
Provided is a safety switch (1), a cam (22) of which rotates about a rotation shaft (221) when triggered by an actuator (10) being inserted into or removed from an opening (213). A switch unit (32) has an operation rod (321) that moves back and forth in accordance with the rotation angle of the cam (22), and detects an inserted state in which the actuator (10) is inserted into the opening (213). In the inserted state, a lock member (25) locks the actuator (10) by engaging with a portion of the cam (22). If removal of the actuator (10) is carried out while the actuator (10) is in the locked state, the cam (22) presses the lock member (25) in a first direction, and the lock member (25) presses a portion of a head case (21) in the first direction. Due to this configuration, the locking strength of the safety switch (1) can be improved.
