In the interest of product improvement, specifications are subject to change. Hints on Correct Use Single-winding type (G5AU) Example of low-power drive circuit 1. The figure below shows a drive circuit (JAPAN PAT. NO. 1239293) in which the latching relay can function like a general-purpose relay from a normal input pulse for switching. 2. Use a charging current of capacitor C to operate the latching relay, which flows suddenly through diode D1, capacitor C, latching relay, and diode D2, and the relay contacts will be put in the locked state. 3. Use a discharging current of capacitor C to release the latching relay, which flows through transistor TR, capacitor C, and the latching relay. 6 Notes: 1. When applying the relay for practical use, make sure of the set or reset state of the relay; then determine the circuit constraints. 2.
