Abstract: PURPOSE:To provide a driving circuit for a two-winding latching relay suppressing the generation of the counter electromotive voltage when the coil current is cut off and preventing the operating time from being prolonged. CONSTITUTION:Diodes 3, 4 are connected in the opposite direction to the coil excitation polarity between two coils 1, 2 exciting the iron core of a two- winding latching relay in the opposite direction, and Zener diodes 7, 8 are connected in series to the diodes 3, 4 in the same direction as the coil excitation polarity.
