Caution: Printed circuit sockets manufactured with "floating" (Loose) terminals. This permits them align with holes circuit board with relay terminals. During mounting soldering socket, vertical float should eliminated terminals seated board. (This accomplished inserting dummy relay socket.) Failure eliminate float cause fracture solder joint separation copper conductor from printed circuit board when relay inserted socket after soldering.
