ABSTRACT:
A latch-relay drive circuit includes a pair of switching devices for separately energizing the set and reset latch-relay coils. To prevent the latch-relay from remaining set once the power fails, an energy storage device, such as a capacitor charged from the power supply, is automatically switched across the reset coil by a switching circuit once the power supply voltage drops below a predetermined voltage thereby automatically resetting the relay.
