Hello! I'm not that great at electrical stuff but I recently got this gig for an Escape Room puzzle where I need to make a 12 volt electromagnet stop working by having 3 buttons pressed at the same time.
Now, the opposite (starting the magnet upon pressing the 3 buttons) is really easy to do, just link the 3 buttons and when they are all pressed, the circuit closes and the magnet works.
But I want the magnet to *stop* when 3 buttons are pressed at the same time, what would the easiest way of doing that be? Simply using NC buttons won't work because just pressing one will open the circuit and it needs to open when all 3 are closed. And I can't use switches either, it has to be a button.
