Mar 24, 2020 at 7:32 comment added Pedro Almeida D Duck is spot on. In this case I'm working with a laser that I want to turn off under certain circumstances for safety reasons, and I would like to keep it off until the user presses a button.
Mar 22, 2020 at 10:00 comment added D Duck The standard reason for something like this is a machine tool - say a drill press. You press the start button and the drill turns. Press stop and it stops. But if you press the emergency stop, (or the mains power fails) when the power returns - you don't want to the drill to turn until you press start again.
