ることを特徴とする継電器の省電力駆動回路。 A second switching element is connected in series with a relay connected to a power source via a first switching element that is controlled on and off by a drive signal, and in parallel with a series circuit of the relay and the second switching element, In order to make the second switching element conductive for a predetermined period of time when the first switching element is conductive, a time constant circuit consisting of a resistor and a capacitor connected in series is connected to the relay in parallel with the second switching element to maintain operation. A holding current carrying resistor is connected in parallel with the resistor of the time constant circuit to transfer the charging energy charged in the capacitor of the time constant circuit when the first switching element is off to the holding current. A power-saving drive circuit for a relay, characterized by connecting a current-carrying resistor and a diode for discharging via the relay.
