This invention relates to a method of eliminating limitation (polarity) in a connecting direction inherent to electronic appliances, electronic components or electrical appliances in all kinds of connections during their production and their practical use. The present invention comprises connecting direction detection means and switching means. One of the terminals of the switching means is controlled to "insulation" and the other, to "conduction", depending on the connecting direction (front and back), an intended circuit is constituted by arbitrary connecting directions (front and back), and the circuit can be normally operated. |
