Caution:
Printed circuit sockets are manufactured with "floating" (Loose) terminals. This
permits them to align with holes in the circuit board and with the relay terminals. During
the mounting and soldering of the socket, vertical float should be eliminated and the
terminals seated on the board. (This may be accomplished by inserting a dummy relay in
the socket.) Failure to eliminate float may cause fracture of the solder joint or separation of
the copper conductor from the printed circuit board when a relay is inserted in the socket
after soldering.
