  • Card edge connector with switching contacts
    Patent number: 5098306
    Abstract: A card edge connector having spring contacts that are partially movable by insertion of a circuit board into the connector. The contacts include two contacts that electrically contact each other when a circuit board is not connected to the connector. The two contacts are moved by insertion of a circuit board into the connector which results in disconnection of the electrical contact between the two contacts. This allows a signal contact to be contacted and grounded by a ground contact while the connector is not in use and, nonetheless allows independent ground and signal functions of the two contacts when a circuit board is connected to the connector.
