I am making vacuum lifts, and I want to put a little safety light on them.
My question is how to do it best to work off battery power (3vdc). Both switches you see are mechanically activated contacts.
What I want-
Initial state shall have no switch activated, and have no parasitic draw (for battery life when not in use). No lights shall be on.
When both the High Pressure switch and the Vacuum switch are triggered, the green light shall be ON. This means it is OK to lift.
When either the High Pressure switch, or the Vacuum switch is cut off, the green light should go OFF, and the red light should come ON. This means the lift lost source pressure, but is still holding vacuum by the reserve tank.
When both switches are cut off, the circuit returns to initial state. (both lights off).
Is this feasible with basic components? I have been racking my brain on this, and not sure if I am over thinking it.
