An external reset switch interrupts power to the relay which turns it off.
Push button latching relay circuit.
Push on connectors will do for the power relay but the latching relay is.
An electrically latched relay is a standard relay with one of its own contacts wired into its coil circuit.
The diagram above shows how such a relay can be used to make a latching relay circuit the circuit has two buttons one is a push to make which closes when pressed but is otherwise open and the other is a push to break which opens when pressed but is otherwise closed.
An external switch initially turns the relay on then it is kept on by its own contact.

I ve searched online and find this normal relay driving solution.
I found promising looking one button two relay circuit.
To stop just press the button connected to relay 2 and the load will turn off and stay off until you push the 1st button again.
Here relay is 24 v dc operated.
At other times the only current drain on the 12v supply is the leakage current of one 22µf capacitor which is very low.
It works as follows.
Step 2 when supply comes to relay coil relay should be on.
These two step we see in following picture relay latching circuit using push button.
When the push to make button is pressed 12v goes across the coil energising the relay.
I ve been trying to design a latching relay driver circuit with using a push button switch.

This circuit has one over on the stock kill switch pushbutton because it keeps the ignition permanently disabled so if the engine is unintentionally cranked via another means it cannot start.
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.
When we press push button relay should be on it means we use normally open type push button because when we press this switch supply goes forward.
This circuit allows an spst momentary pushbutton to act as a push on push off switch using a dpdt latching bi stable relay.
Simple soft power latching circuit for a microcontroller.
The relay only draws current when it is being switched.
Per relay datasheet observe coil polarity.
Single push button relay with reset.
