SCHEMATIC DIAGRAM

Here we will look at the schematic diagram and its values.

FUNCTIONING

Initially we will see two LEDS, one OFF and the other ON, when we feed the PCB with 12VDC it will turn OFF and the output for DC motor control will be off, then when we press ON it will activate the relay and its contacts will change, but when you stop pressing this The relay that was already locked will change its output contacts, then it will activate the output for DC motors and the LED will now turn ON and now if we press OFF it will turn off and change contacts. So successively it will be activating and deactivating by interlocking the relay.

RELAY

Basically we could define the relay as an electrical switch that allows the passage of electrical current when it is closed and interrupts it when it is open, but that is actuated electrically, not manually.

The relay is made up of a coil connected to a current. When the coil is activated, it produces an electromagnetic field that causes the normally open relay contact to close and allows current to pass through a circuit to, for example, light a lamp or start a motor. When we stop supplying current to the coil, the electromagnetic field disappears and the relay contact opens again, leaving the electrical circuit that went to that lamp or motor without current.
