Abstract
Incorrect pairing of subsidiary printed circuit boards on opposite sides of a main circuit board is prevented by providing a key or orientation insert on each subsidiary circuit board which projects more than half way through an aperture in the main circuit board. Only subsidiary circuit boards with orientation inserts that complement one another in the main circuit board aperture can be mounted opposite one another on the main circuit board.
