I ve been trying to design a latching relay driver circuit with using a push button switch.
Push button latching relay circuit.
This circuit allows an spst momentary pushbutton to act as a push on push off switch using a dpdt latching bi stable relay.
When the push to make button is pressed 12v goes across the coil energising the relay.
Active 2 years 6 months ago.
Here relay is 24 v dc operated.
Step 2 when supply comes to relay coil relay should be on.
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.
In this video i will show you how to make touch on touch off switch with relay on off switch latching relay the correct schematic diagram of this circuit htt.
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.
An external switch initially turns the relay on then it is kept on by its own contact.
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.
There are two kinds of latching relays.
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.

It works as follows.
An electrically latched relay is a standard relay with one of its own contacts wired into its coil circuit.
Push on connectors will do for the power relay but the latching relay is.
To use this latching relay circuit just press the button connected to relay 1 and the load will stay on even if the button is released.
An external reset switch interrupts power to the relay which turns it off.
I ve searched online and find this normal relay driving solution.
Single push button relay with reset.
Simple soft power latching circuit for a microcontroller.
The relay only draws current when it is being switched.
These two step we see in following picture relay latching circuit using push button.
Per relay datasheet observe coil polarity.
