PROBLEM TO BE SOLVED: To save the power of a load switch, through which a current always flow for holding the throw operation. SOLUTION: A load switch used, in combination with a controller for the power system, is provided with a throw coil CC to change over a switch 6, when the operation power supply is applied from the controller in order to energize a control relay to turn ON the switch, contacts 5 to operate, after the throwing the switch in, in conjunction with a mechanical part for canceling energization of the throw coil and a latch canceling coil TC for detection by detecting the nonvoltage condition, when the operation voltage from the controller disappears. |
