Abstract: There is disclosed a printed circuit card with pin connector elements along one edge thereof. With two parallel rows of pins which pass through the card and extend out of each side, the same female-type connector element cannot be attached to either side; the two rows of pins are transposed relative to the connector on the two sides of the card. In the invention, however, three parallel rows of pins are provided. The pins of the middle row extend out of each side of the card, while the pins in only one of the outer rows extend out of each side of the card. The same-positioned pins in the outer rows are connected to each other through the circuit card. In this way, the same connector can be disposed on either side of the card and connected to the two rows of pins which extend from that side for establishing an identical electrical connection to the printed circuit.
