Hello,
I need some help picking a switch for a project.
I have a single consumer that needs to be powered by one of two available sources (both sources are 3V dc wires).
So:
position1 = source 1 to load
position 2 = off;
position 3 = source 2 to load
Is it acceptable to take a normal DPDT switch and put the DC sources on the "end" pins and the consumer in the middle (which is essentially backwards from the examples shown) since we're just talking about directing current?
The goal is to have a small project box power the consumer by the USB power source, but if that should be unavailable, then the 2xAA would be the backup.
Thank you for taking a moment to read and apologies if the simple answer is staring me in the face.
