The Germans had it the wrong way. It is an old sanskrit symbol. Ironically you can actually find it on some ancient Jewish synagogues. Unfortunately because of its association with the Nazis (who, as I mentioned, had it backwards) it has forever been tainted. Sort of like inverted pentagrams which used to be a common Christian symbol until it became associated with Satanism in the late 19th century.

Its actually a very common symbol. In its connection to gammadia it was significant in Judaism and especially early Christianity.
