DC Switch on Positive or Negative or Does it Matter?
Hi All. I've set up a few lights on DC circuits and am wondering if it matters if the switch for a given light is on the positive side or the negative. I know with AC you don't want the switch on the negative (non hot) because you could potentially hurt yourself when switching out a light bulb or something, but with DC I would think it wouldn't matter because there is no alternating current. Let me know if I need to rewire my circuit. Thanks!
