That depends, do you want high or a low side switch? There are valid reasons for either depending on what you’re doing.

One that is less likely to kill me. Low side switches leave a “floating” voltage that could leak to ground

I’ve left a floating load that leaked to the ground before.

I’m confused are you saying that negative voltage is more deadly than negative voltage? Just because electrons flow from negative to positive doesn’t mean it’s any more dangerous what moves the electrons is the voltage potential. If you were able to have electrons flow from a source through you to the ground your just as able to have electrons flow from the ground through you to a positive voltage source.

They just don’t know what they’re talking about. Mistook it for AC, where one usually wants the switch on the phase side.

I’m saying there is more shock risk…
