ABSTRACT OF THE DISCLOSURE Device for indicating the positions of printed circuit cards with respect to their connectors, said cards belonging to an operational system in which each of them carries logic components and has a terminal surface carrying conductor elements able to come into contact with the corresponding conductor elements of an electrical connector, the corresponding conductors of the connector and of the card being able to occupy three relative positions: a first or safe contact position between the corresponding conductor elements of the connector and of the card, the card being correctly positioned relative to its connector, a second inter- mediate or non-safe contact position between the corre- sponding conductor elements of the connector and of the card, when the latter is being inserted or removed with respect to its connector, and a third or contact break position between the corresponding conductor elements of the connector and the card, when the card is completely withdrawn from its connector, wherein the device has means sensitive to the positions of the cards in order to supply a position indication logic signal having a first logic state when the cards occupy the first position or when at least one card occupies the third position, the signal having a second logic state when at least one card occupies the second intermediate position.
