I would need to configure a relay so that it doesn’t change state. That is, with one press it stays active until I press again (without a timer). Is that possible?

Hi @Luisma and welcome to our forum.
To me, this sounds like you need a latching relay:
A latching relay is simply a type of switching relay that keeps its last condition or position, even after the activating signal has been removed. In other words, it remains either “On” or “Off” without the power supply. That’s why it’s called a latching relay; its position latches in once activated.
