摘要： PROBLEM TO BE SOLVED: To surely switch the power supply to one of two oil windings only when the current becomes approximate to the holding current sufficient to continuously hold a moving magnetic circuit at the holding position. SOLUTION: This power feed circuit is provided with a switching means 10 controlling the excitation of the first semiconductor element T2 allowing the current feed/cutoff to a secondary winding B2 and a voltage adjusting circuit 11 arranged between a primary winding B1 and the first semiconductor element T2 and connected to the second semiconductor element T1, the primary winding B1, and the controller of the second semiconductor element T1. The second semiconductor element T1 is connected to the controller of the first semiconductor element T2 to release the first semiconductor element T2 when the voltage between the controller and output section of the second semiconductor element T1 reaches the voltage threshold value larger than the value corresponding to the closing action start time of an electromagnet.
