Abstract
Abstract An enclosure and mounting member for printed circuit boards has a first housing member defining the outer front of the enclosure and may have an aperture therein for exposing a front control panel. A second housing member defines the outer rear surface of the enclosure. A front control panel and each of the printed circuit boards held within the enclosure have irregularities such as shallow recesses in opposite outer edges. At least two mounting members are provided, each having a stem portion connectable to the first housing member and a flange portion extending perpendicularly from the stem portion connectable to the second housing member. The stem portions each have spaced irregularities such as pairs of notches which are congruent with and/or otherwise mated to respectively corresponding irregularities of the front panel and each of the printed circuit boards. The irregularities of the mounting members cooperate with the mated irregularities of the front control panel and the printed circuit boards for holding the front control panel and the printed circuit boards in substantially parallel, spaced, planes.
