Hello, Varatharajan.M, A 4-way cross can be hard to distinguish from a 4-way connection, especially if one is in a hurry or not perfectly attentive. If the schematic is photocopied or faxed, the dot can become too small and become "lost". This caused numerous problems in the history of engineering. Thus the preference for showing a 4-way cross as a two 3-way intersection. - Lynne "IBIS training when you need it, where you need it."
