摘要： PROBLEM TO BE SOLVED: To provide a safety switch that can realize small size of a switch body by a simple structure. SOLUTION: The safety switch is provided with a first driving cam 17 which is held in free rotation by a case member 13 and a second driving cam 21 which is contacted by the first driving cam 17 by the energized force of a torsion coil spring 25 at the initial state and of which rotation is locked engaged with a second step part 13b and which is held in free rotation by the case member 13. And when an actuator 3 enters between the both driving cam 17, 21 and the second driving cam 21 is separated from the first driving cam 17, the engagement state of the second cam 21 and the second step 13b is released, and the second driving cam 21 is brought to a state capable of rotation. Then, following that, the first driving cam 17 is rotated interlocked with the entry of the actuator 3, and following this the second driving cam 21 is rotated. By the concurrent rotation of the both driving cams 17, 21 an operating rod 23 moves to an operating part 5 side and contact points 39, 40, 41 of a switch part 7 are changed over.

摘要： PROBLEM TO BE SOLVED: To provide a push button switch capable of reliably performing ON- OFF operation of the push button switch even when one contact is failed while using the push button switch, and a teaching pendant using the same. SOLUTION: Two c-contacts 9a and 9b having a snap action are provided in a switch case 3, and switching mechanisms 11a and 11b for opening/closing the c-contacts 9a and 9b are provided. When a push button 5 is pushed in, the c-contacts 9a and 9b are simultaneously opened/closed by the switching mechanisms 11a and 11b to turn ON/turn OFF the push button switch 1.

摘要： PROBLEM TO BE SOLVED: To provide an actuator for safety switch, which can be used in a rotating door having a small rotation radius, and can selectively convert a moving direction of an operation key into either of a horizontal direction or a vertical direction. SOLUTION: An operating key 2 is held in a base 3 in such a manner that it can be shaken in two directions orthogonal to each other (horizontal and vertical directions). Also, there is provided a means for selectively controlling the shaking of the operating key 2 to either of the two directions (e.g. a guide stopper 4 and a fitting portion 34).

摘要： PROBLEM TO BE SOLVED: To provide an enable device for a teach pendant capable of canceling an ON state before both push button switches become a first OFF state, even if the other push button switch is in an ON state when one push button switch is made in a second OFF state by either one hand. SOLUTION: When a left hand operating push button switch is in an ON state, a second relay RL2 is degaussed, a normally closing contact RL2-1 of the second relay RL2 is made ON, a relay contact circuit RC is made ON, and in this state, when the left hand operating push button switch becomes the second OFF state, a normally closing contact R3-1 of the left hand operating push button switch is made ON, and a third relay RL3 is not degaussed until a right hand operating and left hand operating push button switches return to a first OFF state, and thereby, power supply to first and second circuits is cut off.

摘要： 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.
