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.

Push button latching relay circuit.

Active 2 years 6 months ago. I ve searched online and find this normal relay driving solution. Step 2 when supply comes to relay coil relay should be on. I ve been trying to design a latching relay driver circuit with using a push button switch.

I found promising looking one button two relay circuit. 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. 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. At other times the only current drain on the 12v supply is the leakage current of one 22µf capacitor which is very low. 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. The relay only draws current when it is being switched.

Single push button relay with reset. 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. These two step we see in following picture relay latching circuit using push button. An external reset switch interrupts power to the relay which turns it off.

Per relay datasheet observe coil polarity. Here relay is 24 v dc operated. 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. An external switch initially turns the relay on then it is kept on by its own contact.

When the push to make button is pressed 12v goes across the coil energising the relay. 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. There are two kinds of latching relays.
