I've been trying to design a latching relay driver circuit, with using a push-button switch. Basically when the circuit is powered on, first press in push-button switch make the relay SET, then the second press will make the relay RESET state.
I've searched online and find this normal relay driving solution. But I couldn't figure out how to implement this into single coil and/or dual coil latching relay. I guess dual coil latching relay is easier to drive than the single coil one.
Any help is appreciated. (if possible please provide falstad simulation)
