I want to create an "andon" light/buzzer system for an assembly line. What I mean is at any station in the line I want to have a switch the operator can throw and a buzzer goes off momentarily, while simultaneously a light at his station turns on and stays on till the system is reset (switch turned off?). That is, there is one buzzer for the whole line, but each station has its own light and switch to push/flip on. Any suggestions on how to do this? The wiring, circuit logic that is. I can handle sourcing lights and buzzer of whatever type you guys suggest. The buttons can be momentary or not, whatever is needed for this to work. thanks!
