Abstract
An electrostatic discharge protection device is disclosed which automatically connects selected connector pins of a semiconductor chip package ("SCP") or connectors on printed circuit boards such that the connector pins are held at a common voltage until insertion of the SCP into a receptor or until insertion of a cable into the connector which overcomes an internal resilient bias of the electrostatic discharge protection device causing the common connection to be removed. Removal of the SCP from the receptor or the cable from its connector removes the force which overcomes the bias, thereby reestablishing the common electrical connection thus automatically moving the electrostatic discharge protection device between inoperative and operative positions.
