Technical support:
Refer to inside back cover.
Boldface sockets are normally maintained in stock for immediate delivery.
For KHAU, KHU Relays.
Relays with solder terminals are required for use with sockets.
Printed Circuit Terminals
With Grounding Lug
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.
