<P>PROBLEM TO BE SOLVED: To provide a device for breaking an input of a power supply input of a robot system which can elongate a life tremendously by suppressing a circuit cut failure at emergency and the generation of a heat loss at usual operation, and also eliminating the deterioration of a switch with a contact thereby bringing the maintenance period of the switch with a contact close to its mechanical life. <P>SOLUTION: The device is equipped with a contactless switch 4 which is arranged between an input power supply 1 and the switch 2 with a contact and is electrically connected in series to the contact of the switch 2 with a contact, and a switch controller 5 which controls the switch so that the contactless switch 4 may be closed later than the switch 2 with a contact at the power-on of a robot controller 3 and that the contactless switch 4 may be opened earlier than the switch 2 with a contact at the power break of the robot controller 3. <P>COPYRIGHT: (C)2007,JPO&INPIT |
