Title:
SAFETY SWITCH
Document Type and Number:
Japanese Patent JP3938275
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a safety switch capable of thinning a switch body with a simple structure.
SOLUTION: A pair of intermediate members 17 is rotatably provided axially with a driving cam 15 on both sides of the driving cam 15, and a pair of locking members 19 abutting on an engagement part 15d formed on the peripheral surface of the driving cam 15 to get engaged with it is provided. When the intermediate members 17 rotate around a rotational shaft 13 as an actuator 3 enters, the both intermediate members 17 open the locking member 19 to move it parallel to the rotational shaft 13. Thereby, the driving cam 15 is disengaged from the locking member 19 in order to make the driving cam 15 rotatable, a control rod 21 is protruded in the direction of an operating part 5 by a coil spring 51, and each normally closed contact 39-41 is switched on in order to make an industrial machine operable by supplying electric power to the industrial machine.
