How do I wire a toggle switch for an HF amplifier power supply ?

"Edison developed direct current -- current that runs continually in a single direction, like in a battery or a fuel cell. During the early years of electricity, direct current (shorthanded as DC) was the standard in the U.S.

But there was one problem. Direct current is not easily converted to higher or lower voltages.

Tesla believed that alternating current (or AC) was the solution to this problem. Alternating current reverses direction a certain number of times per second -- 60 in the U.S. -- and can be converted to different voltages relatively easily using a transformer.

Edison, not wanting to lose the royalties he was earning from his direct current patents, began a campaign to discredit alternating current. He spread misinformation saying that alternating current was more dangerous, even going so far as to publicly electrocute stray animals using alternating current to prove his point."

So which do you guys believe is more dangerous when it comes to electrocution, AC or DC?

My personal experience confirms the theory that it's much harder to let go of a given DC voltage than an AC one . . .

Having grabbed hold of 250 - 300V DC a number of times over the years, it hurts a lot more than touching our 240V AC Mains !

I've read your posts in this thread and have come to two conclusions (1) Yes, you have touched your mains many times. (2) You're the only one that thinks it hasn't affected you.

Seeing this thread pop back up I had to read it again.
Noticed one great man that Roger failed to mention.
