Abstract

PURPOSE:To achieve cost down, by using the first winding latching relay which can be switched to both the latch state and return state by the direction of current flowing to the coil. CONSTITUTION:The capacitor 15 is charged ith the positive DC power supply 1 according to the application of the power supply 2, and the capacitor 33 is charged with the negative DC power supply 31. Further, the H signal is output from the delay circuit 21, differentiation charge waveform is obtained at the differentiation circuit 46 to turn on the transistor 41. Further, Latch state is made by feeding the positive DC power supply 31 to the coil A of the one winding latching relay. Next, when the power supply 2 is off, the output of the delay circuit 2 is L signal after a given delay time to turn on the transistor 42 through the differentiation discharge waveform with the differentiation circuit 46. The coil A is excited by taking the capacitor 33 as the power supply with turning-on of the transistor 42, causing it into return state.
