Default Re: WARNING: Live heatsinks & single pole on/off switches in switching power supplies

Deer DR-250ATX[/url] from the early 2000's that's probably not the best PSU in the world... yet, it has a dual pole switch that disconnects both Live and Neutral. I've also seen many higher-end PSUs with a single pole switch. So again, the build quality of the PSU is not necessarily relevant to the type of switch used on the AC line.
I've seen those DPST switches in some higher end Allied-built Modecom units as well, though most of the others use the normal single pole switches, with the small note that they heatshrink them unlike the lower (bottom-of-the-barrel) units.
