If you realized RESPECTIVELY was so important, then why did you miss it in your last post >> Yes, Kiddo, "each switch is connected to one 100 watt, 60 watt, 40 watt."

Your use of "Each" is not a proper use grammatically. You cannot use the word "each" there and claim it is not an ambiguous question. If you still think it is, then read the question just above this post. Ur questions are good though, keep 'em coming. Just trying to annoy u and correct ur grammer.
