<p>An apparatus for housing a power supply comprises a top member (4) and pairs of opposed end and side walls (10, 12, 6, 8). A compartment (20) is formed within and of one piece construction with the top member. A mounting means (25) is formed in the compartment to which a power supply switch transistor can be secured. A cover for the compartment comprises a substantially planar member and a plurality of flanges extending away from the planar member along its edges. Each flange has a dome-shaped projection extending outwardly from the surface of the flange which provides a positive point to point electrical contact with the walls of the compartment when the cover is secured to the top member.</p> |
