An improved edge design for a printed circuit board used with a connector having spring biased contact members. The printed circuit board has a nose piece bonded thereon which is made of a lubritious, insulating material for deflecting the spring biased contact members without causing damage to the members or the electrical contacts thereon. In a preferred embodiment, each spring biased member is fixed in the connector at one end and has a bent portion with an electrical contact on the bent portion. The electrical contact is in an impact protected position when its spring biased member is undeflected, and moves to a contact making position for contact with an input/output tab on the printed circuit board as the spring biased member is deflected around its fixed end during the plugging in operation of the printed circuit board.
