I thought this would be a great first time project for me. I call it a switch bank.
Its kind of like the pushbuttons on an old casetteplayer, for example. The main function is that, if I press a button, it latches. When I press another button, the previous button de-latches, and the new button latches. Only one button can be pressed down at any given time. Another "bonus" would be that, if I press the already pressed button a second time, it unlatches.
This I would like to do with illuminated momentary switches.
Did I make myself understandable? Hope so.
