Hi Gary,
For the symbol with the arrow pointing into the house, I would say that the wall wart is intended to be used indoors, not outdoors. As to the symbols origin, I have no idea. But, you might want to check out ISO7000. There's many, many symbols in my 1989 copy (many I'm sure that you'd recognize) and I'm sure that more have been added since then. As for the "C" symbol, I have have no idea. However, let's wait and see if any of our learned colleagues might know. IHTH. Best regards, Ron Pickard [email protected] Gary.McInturff@worldwide packets.com To: [email protected] Sent by: cc: owner-emc-pstc@majordomo Subject: strange symbols (to me anyway) .ieee.org 01/02/2003 03:42 PM Please respond to Gary.McInturff I have a small double insulated wall wart type power supply. 120 Vac in, 12 Vdc out has a symbol of a house with an arrow pointing inside the house. What is that symbol and whence did it come. This one is going to be tough to describe, and is on a little wireless device. A nearly closed "C". The upper half has a horizontal "lightning bolt" separating top and bottom. In the bottom portion of this symbol is what appears to be a capacitor with horizontal plates. (both plates are represented by flat lines rather than 1 flat and one an arc). Thanks Gary This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
