I'm working on a project that will incorporate several test circuits into one instrument case. The circuits are simple (e.g., 555 astables, etc.). I'd like to use one power supply to run the whole thing.
Because no two circuits would ever be in use at the same time, I'm assuming it will be possible to run the circuits in parallel as long as I connect a diode between each circuit's ground/negative lead and the power supply's ground, as presented below:
(-) Lead -> (A) Diode (K) -> (-) Battery
Am I on the right track here? I'd like to avoid using a six/deuce rotary switch or anything like that to switch power from circuit to circuit.
Thanks.
