Two switches, A (first) and B (second). Make = circuit is made; Break = circuit is broken
A and B both are released.
If A is pushed before B, Make
When B is pushed, Break
When A is released and pushed again, Make
etc.
Question, what happens if B is held while A is released and then pushed again?
If B is pushed before A, ignore A always until B is released.
Is this correct?
The "released and pushed again" part means tis probably will take at lease one flip flop.
What is the voltage range of the signal being made and broken?
What power is available to run the logic circuit?
Does this have to be industrially rugged (lots of interference, big motors arc welders in the area, etc.)?
