Latching Relay Circuit Momentary Switch

The latching relay maintains its position after the actuating switch has been released so it performs a basic memory function.

Latching relay circuit momentary switch.

This circuit will change a momentary pushbutton switch into a always on switch. This circuit allows an spst momentary pushbutton to act as a push on push off switch using a dpdt latching bi stable relay. This circuit allows an spst momentary pushbutton to act as a push on push off switch using a dpdt latching bi stable relay. It works as follows.

Step 2 when supply comes to relay coil relay should be on. With less than 5 dollars in parts you can do what is needed to convert a pulsed momentary output into a latched one instantly. These two step we see in following picture relay latching circuit using push button. It is controlled by two momentary acting switches or sensors one that sets the relay and the other resets the relay.

Figure 1 circuit converts momentary action push switch into latching power switch. Latching locking relay circuit. To understand how the circuit operates assume that the dc power supply v s has just been applied capacitor c1 is initially uncharged and q1 is off. It was originally intended to allow a single pushbutton switch on the dash of a vintage car to provide a latched function.

What will i think of next. A latching relay is a two position electrically actuated switch. Other methods of operating can be used i used an automotive car remote control central door lockin. A general purpose relay switch is designed to function as a bridge on one or more connected devices or circuits receiving an input signal from one source and transmitting an on off set reset output to another.

If you would like to turn it off you will need another switch. The relay only draws current when it is being switched. 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. Here relay is 24 v dc operated.

The relay only draws current when it is being switched.
