Is it possible (or is there a trick …) to use 1 of the 4 relays on the VMB4RY as a normally-closed connection?
So I always want the relay to be on, except if I press a button (as long as I hold it or just for let say a 10th of second).
I know it’s possible with a VMB1RY, but a have a spare VMB4RY relay so I’m looking for the cheapest sollution.
It would also be nice to (re) start the relay as normally-closed again after a power breakdown.
Any hints are welcome
