This might be a bit of a n00b question, but it's something that gave me a lot of thinking lately, as I purchased some pretty nice pedals and the fear of damaging them has grown. Long story short: I see no PSUs with an on/off switch, so in order to turn power off one just pulls the plug, right? But I have seen some accessory connector (like those by Temple Audio) which feature a switch. So I was wondering: does pulling off the plug cause any harm to the pedals and/or the PSU itself? Is the use of a switch "safer"? From an ignorant point of view, pulling the plug seems brutal to me, but the complete absence of dedicated switches on the PSUs leaves me wondering.
